[diagnostics] Support --turbo-profiling for builtins Currently, if d8 is run with the --turbo-profiling flag, it prints info about every TurboFan-compiled function. This info includes the number of times that each basic block in the function was run. It also includes text representations of the function's schedule and code, so that the person reading the output can associate counters with blocks of code. The data about each function is currently stored in a BasicBlockProfiler::Data instance, which is attached to a list owned by the singleton BasicBlockProfiler. Each Data contains an std::vector<uint32_t> which represents how many times each block in the function has executed. The generated code for each block uses a raw pointer into the storage of that vector to implement incrementing the counter. With this change, if you compile with v8_enable_builtins_profiling and then run with --turbo-profiling, d8 will print that same info about builtins too. In order to generate code that can survive being serialized to a snapshot and reloaded, this change uses counters in the JS heap instead of a std::vector outside the JS heap. The steps for instrumentation are as follows: 1. Between scheduling and instruction selection, add code to increment the counter for each block. The counters array doesn't yet exist at this point, and allocation is disallowed, so at this point the code refers to a special marker value. 2. During finalization of the code, allocate a BasicBlockProfilingData object on the JS heap containing data equivalent to what is stored in BasicBlockProfiler::Data. This includes a ByteArray that is big enough to store the counters for each block. 3. Patch the reference in the BuiltinsConstantsTableBuilder so that instead of referring to the marker object, it now refers to this ByteArray. Also add the BasicBlockProfilingData object to a list that is attached to the heap roots so it can be easily accessed for printing. Because these steps include modifying the BuiltinsConstantsTableBuilder, this procedure is only applicable to builtins. Runtime-generated code still uses raw pointers into std::vector instances. In order to keep divergence between these code paths to a minimum, most work is done referring to instances of BasicBlockProfiler::Data (the C++ class), and functions are provided to copy back and forth between that type and BasicBlockProfilingData (the JS heap object). This change is intended only to make --turbo-profiling work consistently on more kinds of functions, but with some further work, this data could form the basis for: - code coverage info for fuzzers, and/or - hot-path info for profile-guided optimization.

Profile-guided optimization of builtins Design doc: https://docs.google.com/document/d/1szInbXZfaErWW70d30hJsOLL0Es-l5_g8d2rXm1ZBqI/edit?usp=sharing V8 can already collect data about how many times each basic block in the builtins is run. This change enables using that data for profile-guided optimization. New comments in BUILD.gn describe how to use this feature. A few implementation details worth mentioning, which aren't covered in the design doc: - BasicBlockProfilerData currently contains an array of RPO numbers. However, this array is always just [0, 1, 2, 3, ...], so this change removes that array. A new DCHECK in BasicBlockInstrumentor::Instrument ensures that the removal is valid. - RPO numbers, while useful for printing data that matches with the stringified schedule, are not useful for matching profiling data with blocks that haven't been scheduled yet. This change adds a new array of block IDs in BasicBlockProfilerData, so that block counters can be used for PGO. - Basic block counters need to be written to a file so that they can be provided to a subsequent run of mksnapshot, but the design doc doesn't specify the transfer format or what file is used. In this change, I propose using the existing v8.log file for that purpose. Block count records look like this: block,TestLessThanHandler,37,29405 This line indicates that block ID 37 in TestLessThanHandler was run 29405 times. If multiple lines refer to the same block, the reader adds them all together. I like this format because it's easy to use: - V8 already has robust logic for creating the log file, naming it to avoid conflicts in multi-process situations, etc. - Line order doesn't matter, and interleaved writes from various logging sources are fine, given that V8 writes each line atomically. - Combining multiple sources of profiling data is as simple as concatenating their v8.log files together. - It is a good idea to avoid making any changes based on profiling data if the function being compiled doesn't match the one that was profiled, since it is common to use profiling data downloaded from a central lab which is updated only periodically. To check whether a function matches, I propose using a hash of the Graph state right before scheduling. This might be stricter than necessary, as some changes to the function might be small enough that the profile data is still relevant, but I'd rather err on the side of not making incorrect changes. This hash is also written to the v8.log file, in a line that looks like this: builtin_hash,LdaZeroHandler,3387822046 Bug: v8:10470 Change-Id: I429e5ce5efa94e01e7489deb3996012cf860cf13 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2220765 Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Reviewed-by: Tobias Tebbi <tebbi@chromium.org> Cr-Commit-Position: refs/heads/master@{#69008}

[heap] Share RO_SPACE pages with pointer compression This allows the configuration v8_enable_shared_ro_heap and v8_enable_pointer_compression on Linux and Android, although it still defaults to off. When pointer compression and read-only heap sharing are enabled, sharing is achieved by allocating ReadOnlyPages in shared memory that are retained in the shared ReadOnlyArtifacts object. These ReadOnlyPages are then remapped into the address space of the Isolate ultimately using mremap. To simplify the creation process the ReadOnlySpace memory for the first Isolate is created as before without any sharing. It is only when the ReadOnlySpace memory has been finalized that the shared memory is allocated and has its contents copied into it. The original memory is then released (with PC this means it's just released back to the BoundedPageAllocator) and immediately re-allocated as a shared mapping. Because we would like to make v8_enable_shared_ro_heap default to true at some point but can't make this conditional on the value returned by a method in the code we are yet to compile, the code required for sharing has been mostly changed to use ifs with ReadOnlyHeap::IsReadOnlySpaceShared() instead of #ifdefs except where a compile error would result due to the absence of a class members without sharing. IsReadOnlySpaceShared() will evaluate CanAllocateSharedPages in the platform PageAllocator (with pointer compression and sharing enabled) once and cache that value so sharing cannot be toggled during the lifetime of the process.

[heap] Add object start bitmap for conservative stack scanning With conservative stack scanning enabled, a snapshot of the call stack upon entry to GC will be used to determine part of the root-set. When the collector walks the stack, it looks at each value and determines whether it could be a potential on-heap object pointer. However, unlike with Handles, these on-stack pointers aren't guaranteed to point to the start of the object: the compiler may decide hide these pointers, and create interior pointers in C++ frames which the GC doesn't know about. The solution to this is to include an object start bitmap in the header of each page. Each bit in the bitmap represents a word in the page payload which is set when an object is allocated. This means that when the collector finds an arbitrary potential pointer into the page, it can walk backwards through the bitmap until it finds the relevant object's base pointer. To prevent the bitmap becoming stale after compaction, it is rebuilt during object sweeping. This is experimental, and currently only works with inline allocation disabled, and single generational collection.

[heap] Add object start bitmap for conservative stack scanning With conservative stack scanning enabled, a snapshot of the call stack upon entry to GC will be used to determine part of the root-set. When the collector walks the stack, it looks at each value and determines whether it could be a potential on-heap object pointer. However, unlike with Handles, these on-stack pointers aren't guaranteed to point to the start of the object: the compiler may decide hide these pointers, and create interior pointers in C++ frames which the GC doesn't know about. The solution to this is to include an object start bitmap in the header of each page. Each bit in the bitmap represents a word in the page payload which is set when an object is allocated. This means that when the collector finds an arbitrary potential pointer into the page, it can walk backwards through the bitmap until it finds the relevant object's base pointer. To prevent the bitmap becoming stale after compaction, it is rebuilt during object sweeping. This is experimental, and currently only works with inline allocation disabled, and single generational collection.

Add initial support for Wasm debugging with LLDB: implements a GDB-remote stub This is the first piece of the wasm debugging prototype (besides the changes to add/remove breakpoints in WasmModuleObject made with https://chromium.googlesource.com/v8/v8.git/+/e699f39caed9a23f8e20bd3a0386a3236e272737). This changelist adds the infrastructure for a GDB-remote stub that will be used to manage debugging sessions via the gdb-remote protocol. It enables the creation and termination of debugging sessions over TCP connections that are managed in a separate thread. The logic to actually send, receive and decode GDB-remote packets will be part of a future changelist. Build with: v8_enable_wasm_gdb_remote_debugging = true Run with: --wasm-gdb-remote Enables Wasm debugging with LLDB (default: false) --wasm-gdb-remote-port TCP port to be used for debugging (default: 8765) --wasm-pause-waiting-for-debugger Pauses the execution of Wasm code waiting for a debugger (default: false) --trace-wasm-gdb-remote Enables tracing of Gdb-remote packets (default: false) Note that most of this code is "borrowed" from the code of the Chromium NaCL GDB-remote stub (located in Chromium in src\native_client\src\trusted\debug_stub). Implementation details: - class GdbServer acts as a singleton manager for the gdb-remote stub. It is instantiated as soon as the first Wasm module is loaded in the Wasm engine. - class GdbServerThread spawns the worker thread for the TCP connection. - class Transport manages the socket connection, in a portable way. - class Session represents a remote debugging session. - class Target represents a debugging target and it’s the place where the debugging packets will be processed and will implement the logic to debug a Wasm engine.

[torque] Generate instance types Design doc: https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit Changes from the design doc: - Changed to use 'class' declarations rather than 'type' declarations for things that need instance types but whose layout is not known to Torque. These declarations end with a semicolon rather than having a full set of methods and fields surrounded by {}. If the class's name should not be treated as a class name in generated output (because it's actually a template, or doesn't exist at all), we use the standard 'generates' clause to declare the most appropriate C++ class. - Removed @instanceTypeName. - @highestInstanceType became @highestInstanceTypeWithinParentClassRange to indicate a semantic change: it no longer denotes the highest instance type globally, but only within the range of values for its immediate parent class. This lets us use it for Oddball, which is expected to be the highest primitive type. - Added new abstract classes JSCustomElementsObject and JSSpecialObject to help with some range checks. - Added @lowestInstanceTypeWithinParentClassRange so we can move the new classes JSCustomElementsObject and JSSpecialObject to the beginning of the JSObject range. This seems like the least-brittle way to establish ranges that also include JSProxy (and these ranges are verified with static assertions in instance-type.h). - Renamed @instanceTypeValue to @apiExposedInstanceTypeValue. - Renamed @instanceTypeFlags to @reserveBitsInInstanceType. This change introduces the new annotations and adds the ability for Torque to assign instance types that satisfy those annotations. Torque now emits two new macros: - TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the InstanceType enumeration - TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String parts of INSTANCE_TYPE_LIST The design document mentions a couple of other macro lists that could easily be replaced, but I'd like to defer those to a subsequent checkin because this one is already pretty large.

[torque] generate C++ class definitions per Torque file This CL splits the class definitions per .tq file, to realize the following relationship: A class defined in src/objects/foo.tq has a C++ definition in src/objects/foo.h. Torque then generates: - torque-generated/src/objects/foo-tq.inc An include file (no proper header) to be included in src/objects/foo.h containing the Torque-generated C++ class definition. - torque-generated/src/objects/foo-tq-inl.inc An include file (no proper header) to be included in src/objects/foo-inl.h containing inline function definitions. - torque-generated/src/objects/foo-tq.cc A source file including src/objects/foo-inl.h that contains non-inline function definitions. Advantages of this approach: - Avoid big monolithic headers and preserve the work that went into splitting objects.h - Moving a definition to Torque keeps everything in the same place from a C++ viewpoint, including a fully Torque-generated C++ class definition. - The Torque-generated include files do not need to be independent headers, necessary includes or forward declarations can just be added to the headers that include them. Drive-by changes: A bunch of definitions and files had to be moved or created to realize a consistent 1:1 relationship between .tq files and C++ headers.

[torque] generate C++ class definitions per Torque file This CL splits the class definitions per .tq file, to realize the following relationship: A class defined in src/objects/foo.tq has a C++ definition in src/objects/foo.h. Torque then generates: - torque-generated/src/objects/foo-tq.inc An include file (no proper header) to be included in src/objects/foo.h containing the Torque-generated C++ class definition. - torque-generated/src/objects/foo-tq-inl.inc An include file (no proper header) to be included in src/objects/foo-inl.h containing inline function definitions. - torque-generated/src/objects/foo-tq.cc A source file including src/objects/foo-inl.h that contains non-inline function definitions. Advantages of this approach: - Avoid big monolithic headers and preserve the work that went into splitting objects.h - Moving a definition to Torque keeps everything in the same place from a C++ viewpoint, including a fully Torque-generated C++ class definition. - The Torque-generated include files do not need to be independent headers, necessary includes or forward declarations can just be added to the headers that include them. Drive-by changes: A bunch of definitions and files had to be moved or created to realize a consistent 1:1 relationship between .tq files and C++ headers.

[embedded handlers] Store the handlers without gaps Previously the builtins table had a value for every single OperandScale/Bytecode combination regardless of whether it was valid. This change makes it so that only valid bytecode handlers are stored in the builtins table. This prevents placeholders being serialized into the snapshot (and embedded into the binary) saving 9KB in CODE_SPACE/OLD_SPACE and 2.5KB in the embedded data as well as 66 entries in the builtins table. To do this, it generates a new header file bytecodes-builtins-list.h which is created from the BYTECODE_LIST and OPERAND_SCALE_LIST macros. Since list macros cannot be used to conditionally generate elements in the C-preprocessor, this is done by generator executable, compiled from interpreter/generate-flat-headers.cc. Additionally the generator creates the flat bytecode list so that it is transposed from the previous result, i.e. the results are grouped by bytecode and then operand scale rather than operand scale then bytecode. This should give better locality for commonly used bytecodes and may allow less commonly used ExtraWide bytecodes to never be mapped into memory at all. The cost to storing the handlers densely is that looking up a handler now requires a binary search through the builtins table, but this should only happen during debugging. It is also fixable at least for non-wide handlers and could be improved for wide ones if the need arises.

[embedded handlers] Store the handlers without gaps Previously the builtins table had a value for every single OperandScale/Bytecode combination regardless of whether it was valid. This change makes it so that only valid bytecode handlers are stored in the builtins table. This prevents placeholders being serialized into the snapshot (and embedded into the binary) saving 9KB in CODE_SPACE/OLD_SPACE and 2.5KB in the embedded data as well as 66 entries in the builtins table. To do this, it generates a new header file bytecodes-builtins-list.h which is created from the BYTECODE_LIST and OPERAND_SCALE_LIST macros. Since list macros cannot be used to conditionally generate elements in the C-preprocessor, this is done by generator executable, compiled from interpreter/generate-flat-headers.cc. Additionally the generator creates the flat bytecode list so that it is transposed from the previous result, i.e. the results are grouped by bytecode and then operand scale rather than operand scale then bytecode. This should give better locality for commonly used bytecodes and may allow less commonly used ExtraWide bytecodes to never be mapped into memory at all. The cost to storing the handlers densely is that looking up a handler now requires a binary search through the builtins table, but this should only happen during debugging. It is also fixable at least for non-wide handlers and could be improved for wide ones if the need arises.

[diagnostics] Support --turbo-profiling for builtins Currently, if d8 is run with the --turbo-profiling flag, it prints info about every TurboFan-compiled function. This info includes the number of times that each basic block in the function was run. It also includes text representations of the function's schedule and code, so that the person reading the output can associate counters with blocks of code. The data about each function is currently stored in a BasicBlockProfiler::Data instance, which is attached to a list owned by the singleton BasicBlockProfiler. Each Data contains an std::vector<uint32_t> which represents how many times each block in the function has executed. The generated code for each block uses a raw pointer into the storage of that vector to implement incrementing the counter. With this change, if you compile with v8_enable_builtins_profiling and then run with --turbo-profiling, d8 will print that same info about builtins too. In order to generate code that can survive being serialized to a snapshot and reloaded, this change uses counters in the JS heap instead of a std::vector outside the JS heap. The steps for instrumentation are as follows: 1. Between scheduling and instruction selection, add code to increment the counter for each block. The counters array doesn't yet exist at this point, and allocation is disallowed, so at this point the code refers to a special marker value. 2. During finalization of the code, allocate a BasicBlockProfilingData object on the JS heap containing data equivalent to what is stored in BasicBlockProfiler::Data. This includes a ByteArray that is big enough to store the counters for each block. 3. Patch the reference in the BuiltinsConstantsTableBuilder so that instead of referring to the marker object, it now refers to this ByteArray. Also add the BasicBlockProfilingData object to a list that is attached to the heap roots so it can be easily accessed for printing. Because these steps include modifying the BuiltinsConstantsTableBuilder, this procedure is only applicable to builtins. Runtime-generated code still uses raw pointers into std::vector instances. In order to keep divergence between these code paths to a minimum, most work is done referring to instances of BasicBlockProfiler::Data (the C++ class), and functions are provided to copy back and forth between that type and BasicBlockProfilingData (the JS heap object). This change is intended only to make --turbo-profiling work consistently on more kinds of functions, but with some further work, this data could form the basis for: - code coverage info for fuzzers, and/or - hot-path info for profile-guided optimization.

Profile-guided optimization of builtins Design doc: https://docs.google.com/document/d/1szInbXZfaErWW70d30hJsOLL0Es-l5_g8d2rXm1ZBqI/edit?usp=sharing V8 can already collect data about how many times each basic block in the builtins is run. This change enables using that data for profile-guided optimization. New comments in BUILD.gn describe how to use this feature. A few implementation details worth mentioning, which aren't covered in the design doc: - BasicBlockProfilerData currently contains an array of RPO numbers. However, this array is always just [0, 1, 2, 3, ...], so this change removes that array. A new DCHECK in BasicBlockInstrumentor::Instrument ensures that the removal is valid. - RPO numbers, while useful for printing data that matches with the stringified schedule, are not useful for matching profiling data with blocks that haven't been scheduled yet. This change adds a new array of block IDs in BasicBlockProfilerData, so that block counters can be used for PGO. - Basic block counters need to be written to a file so that they can be provided to a subsequent run of mksnapshot, but the design doc doesn't specify the transfer format or what file is used. In this change, I propose using the existing v8.log file for that purpose. Block count records look like this: block,TestLessThanHandler,37,29405 This line indicates that block ID 37 in TestLessThanHandler was run 29405 times. If multiple lines refer to the same block, the reader adds them all together. I like this format because it's easy to use: - V8 already has robust logic for creating the log file, naming it to avoid conflicts in multi-process situations, etc. - Line order doesn't matter, and interleaved writes from various logging sources are fine, given that V8 writes each line atomically. - Combining multiple sources of profiling data is as simple as concatenating their v8.log files together. - It is a good idea to avoid making any changes based on profiling data if the function being compiled doesn't match the one that was profiled, since it is common to use profiling data downloaded from a central lab which is updated only periodically. To check whether a function matches, I propose using a hash of the Graph state right before scheduling. This might be stricter than necessary, as some changes to the function might be small enough that the profile data is still relevant, but I'd rather err on the side of not making incorrect changes. This hash is also written to the v8.log file, in a line that looks like this: builtin_hash,LdaZeroHandler,3387822046 Bug: v8:10470 Change-Id: I429e5ce5efa94e01e7489deb3996012cf860cf13 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2220765 Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Reviewed-by: Tobias Tebbi <tebbi@chromium.org> Cr-Commit-Position: refs/heads/master@{#69008}

[diagnostics] Support --turbo-profiling for builtins Currently, if d8 is run with the --turbo-profiling flag, it prints info about every TurboFan-compiled function. This info includes the number of times that each basic block in the function was run. It also includes text representations of the function's schedule and code, so that the person reading the output can associate counters with blocks of code. The data about each function is currently stored in a BasicBlockProfiler::Data instance, which is attached to a list owned by the singleton BasicBlockProfiler. Each Data contains an std::vector<uint32_t> which represents how many times each block in the function has executed. The generated code for each block uses a raw pointer into the storage of that vector to implement incrementing the counter. With this change, if you compile with v8_enable_builtins_profiling and then run with --turbo-profiling, d8 will print that same info about builtins too. In order to generate code that can survive being serialized to a snapshot and reloaded, this change uses counters in the JS heap instead of a std::vector outside the JS heap. The steps for instrumentation are as follows: 1. Between scheduling and instruction selection, add code to increment the counter for each block. The counters array doesn't yet exist at this point, and allocation is disallowed, so at this point the code refers to a special marker value. 2. During finalization of the code, allocate a BasicBlockProfilingData object on the JS heap containing data equivalent to what is stored in BasicBlockProfiler::Data. This includes a ByteArray that is big enough to store the counters for each block. 3. Patch the reference in the BuiltinsConstantsTableBuilder so that instead of referring to the marker object, it now refers to this ByteArray. Also add the BasicBlockProfilingData object to a list that is attached to the heap roots so it can be easily accessed for printing. Because these steps include modifying the BuiltinsConstantsTableBuilder, this procedure is only applicable to builtins. Runtime-generated code still uses raw pointers into std::vector instances. In order to keep divergence between these code paths to a minimum, most work is done referring to instances of BasicBlockProfiler::Data (the C++ class), and functions are provided to copy back and forth between that type and BasicBlockProfilingData (the JS heap object). This change is intended only to make --turbo-profiling work consistently on more kinds of functions, but with some further work, this data could form the basis for: - code coverage info for fuzzers, and/or - hot-path info for profile-guided optimization.

[async-iteration] implement AsyncGenerator - Introduce new struct AsyncGeneratorRequest, which holds information pertinent to resuming execution of an AsyncGenerator, such as the Promise associated with the async generator request. It is intended to be used as a singly linked list, and holds a pointer to the next item in te queue. - Introduce JSAsyncGeneratorObject (subclass of JSGeneratorObject), which includes several new internal fields (`queue` which contains a singly linked list of AsyncGeneratorRequest objects, and `await_input` which contains the sent value from an Await expression (This is necessary to prevent function.sent (used by yield*) from having the sent value observably overwritten during execution). - Modify SuspendGenerator to accept a set of Flags, which indicate whether the suspend is for a Yield or Await, and whether it takes place on an async generator or ES6 generator. - Introduce interpreter intrinsics and TF intrinsic lowering for accessing the await input of an async generator - Modify the JSGeneratorStore operator to understand whether or not it's suspending for a normal yield, or an AsyncGenerator Await. This ensures appropriate registers are stored. - Add versions of ResumeGeneratorTrampoline which store the input value in a different field depending on wether it's an AsyncGenerator Await resume, or an ordinary resume. Also modifies whether debug code will assert that the generator object is a JSGeneratorObject or a JSAsyncGeneratorObject depending on the resume type.

Profile-guided optimization of builtins Design doc: https://docs.google.com/document/d/1szInbXZfaErWW70d30hJsOLL0Es-l5_g8d2rXm1ZBqI/edit?usp=sharing V8 can already collect data about how many times each basic block in the builtins is run. This change enables using that data for profile-guided optimization. New comments in BUILD.gn describe how to use this feature. A few implementation details worth mentioning, which aren't covered in the design doc: - BasicBlockProfilerData currently contains an array of RPO numbers. However, this array is always just [0, 1, 2, 3, ...], so this change removes that array. A new DCHECK in BasicBlockInstrumentor::Instrument ensures that the removal is valid. - RPO numbers, while useful for printing data that matches with the stringified schedule, are not useful for matching profiling data with blocks that haven't been scheduled yet. This change adds a new array of block IDs in BasicBlockProfilerData, so that block counters can be used for PGO. - Basic block counters need to be written to a file so that they can be provided to a subsequent run of mksnapshot, but the design doc doesn't specify the transfer format or what file is used. In this change, I propose using the existing v8.log file for that purpose. Block count records look like this: block,TestLessThanHandler,37,29405 This line indicates that block ID 37 in TestLessThanHandler was run 29405 times. If multiple lines refer to the same block, the reader adds them all together. I like this format because it's easy to use: - V8 already has robust logic for creating the log file, naming it to avoid conflicts in multi-process situations, etc. - Line order doesn't matter, and interleaved writes from various logging sources are fine, given that V8 writes each line atomically. - Combining multiple sources of profiling data is as simple as concatenating their v8.log files together. - It is a good idea to avoid making any changes based on profiling data if the function being compiled doesn't match the one that was profiled, since it is common to use profiling data downloaded from a central lab which is updated only periodically. To check whether a function matches, I propose using a hash of the Graph state right before scheduling. This might be stricter than necessary, as some changes to the function might be small enough that the profile data is still relevant, but I'd rather err on the side of not making incorrect changes. This hash is also written to the v8.log file, in a line that looks like this: builtin_hash,LdaZeroHandler,3387822046 Bug: v8:10470 Change-Id: I429e5ce5efa94e01e7489deb3996012cf860cf13 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2220765 Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Reviewed-by: Tobias Tebbi <tebbi@chromium.org> Cr-Commit-Position: refs/heads/master@{#69008}

This change adds a new array of block IDs in BasicBlockProfilerData, so that block counters can be used for PGO. - Basic block counters need to be written to a file so that they can be provided to a subsequent run of mksnapshot, but the design doc doesn't specify the transfer format or what file is used. In this change, I propose using the existing v8.log file for that purpose. Block count records look like this: block,TestLessThanHandler,37,29405 This line indicates that block ID 37 in TestLessThanHandler was run 29405 times. If multiple lines refer to the same block, the reader adds them all together. I like this format because it's easy to use: - V8 already has robust logic for creating the log file, naming it to avoid conflicts in multi-process situations, etc. - Line order doesn't matter, and interleaved writes from various logging sources are fine, given that V8 writes each line atomically. - Combining multiple sources of profiling data is as simple as concatenating their v8.log files together. - It is a good idea to avoid making any changes based on profiling data if the function being compiled doesn't match the one that was profiled, since it is common to use profiling data downloaded from a central lab which is updated only periodically. To check whether a function matches, I propose using a hash of the Graph state right before scheduling. This might be stricter than necessary, as some changes to the function might be small enough that the profile data is still relevant, but I'd rather err on the side of not making incorrect changes. This hash is also written to the v8.log file, in a line that looks like this: builtin_hash,LdaZeroHandler,3387822046 Bug: v8:10470 Change-Id: I429e5ce5efa94e01e7489deb3996012cf860cf13 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2220765 Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Reviewed-by: Tobias Tebbi <tebbi@chromium.org> Cr-Commit-Position: refs/heads/master@{#69008}

Reland "[compiler] Optionally apply an offset to stack checks" This is a reland of 4a16305b6555c0661645f8f2c9d890798f8d5e84 The original CL adjust only one part of the stack check, namely the comparison of the stack pointer against the stack limit in generated code. There is a second part: Runtime::kStackGuard repeats this check to distinguish between a stack overflow and an interrupt request. This second part in runtime must apply the offset just like in generated code. It is implemented in this reland by the StackCheckOffset operator and a new StackGuardWithGap runtime function. Original change's description: > [compiler] Optionally apply an offset to stack checks > > The motivation behind this change is that the frame size of an optimized > function and its unoptimized version may differ, and deoptimization > may thus trigger a stack overflow. The solution implemented in this CL > is to optionally apply an offset to the stack check s.t. the check > becomes 'sp - offset > limit'. The offset is applied to stack checks at > function-entry, and is set to the difference between the optimized and > unoptimized frame size. > > A caveat: OSR may not be fully handled by this fix since we've already > passed the function-entry stack check. A possible solution would be to > *not* skip creation of function-entry stack checks for inlinees. > > This CL: 1. annotates stack check nodes with the stack check kind, where > kind is one of {function-entry,iteration-body,unknown}. 2. potentially > allocates a temporary register to store the result of the 'sp - offset' > in instruction selection (and switches input registers to 'unique' > mode). 3.

[embedded handlers] Store the handlers without gaps Previously the builtins table had a value for every single OperandScale/Bytecode combination regardless of whether it was valid. This change makes it so that only valid bytecode handlers are stored in the builtins table. This prevents placeholders being serialized into the snapshot (and embedded into the binary) saving 9KB in CODE_SPACE/OLD_SPACE and 2.5KB in the embedded data as well as 66 entries in the builtins table. To do this, it generates a new header file bytecodes-builtins-list.h which is created from the BYTECODE_LIST and OPERAND_SCALE_LIST macros. Since list macros cannot be used to conditionally generate elements in the C-preprocessor, this is done by generator executable, compiled from interpreter/generate-flat-headers.cc. Additionally the generator creates the flat bytecode list so that it is transposed from the previous result, i.e. the results are grouped by bytecode and then operand scale rather than operand scale then bytecode. This should give better locality for commonly used bytecodes and may allow less commonly used ExtraWide bytecodes to never be mapped into memory at all. The cost to storing the handlers densely is that looking up a handler now requires a binary search through the builtins table, but this should only happen during debugging. It is also fixable at least for non-wide handlers and could be improved for wide ones if the need arises.

Profile-guided optimization of builtins Design doc: https://docs.google.com/document/d/1szInbXZfaErWW70d30hJsOLL0Es-l5_g8d2rXm1ZBqI/edit?usp=sharing V8 can already collect data about how many times each basic block in the builtins is run. This change enables using that data for profile-guided optimization. New comments in BUILD.gn describe how to use this feature. A few implementation details worth mentioning, which aren't covered in the design doc: - BasicBlockProfilerData currently contains an array of RPO numbers. However, this array is always just [0, 1, 2, 3, ...], so this change removes that array. A new DCHECK in BasicBlockInstrumentor::Instrument ensures that the removal is valid. - RPO numbers, while useful for printing data that matches with the stringified schedule, are not useful for matching profiling data with blocks that haven't been scheduled yet. This change adds a new array of block IDs in BasicBlockProfilerData, so that block counters can be used for PGO. - Basic block counters need to be written to a file so that they can be provided to a subsequent run of mksnapshot, but the design doc doesn't specify the transfer format or what file is used. In this change, I propose using the existing v8.log file for that purpose. Block count records look like this: block,TestLessThanHandler,37,29405 This line indicates that block ID 37 in TestLessThanHandler was run 29405 times. If multiple lines refer to the same block, the reader adds them all together. I like this format because it's easy to use: - V8 already has robust logic for creating the log file, naming it to avoid conflicts in multi-process situations, etc. - Line order doesn't matter, and interleaved writes from various logging sources are fine, given that V8 writes each line atomically. - Combining multiple sources of profiling data is as simple as concatenating their v8.log files together. - It is a good idea to avoid making any changes based on profiling data if the function being compiled doesn't match the one that was profiled, since it is common to use profiling data downloaded from a central lab which is updated only periodically. To check whether a function matches, I propose using a hash of the Graph state right before scheduling. This might be stricter than necessary, as some changes to the function might be small enough that the profile data is still relevant, but I'd rather err on the side of not making incorrect changes. This hash is also written to the v8.log file, in a line that looks like this: builtin_hash,LdaZeroHandler,3387822046 Bug: v8:10470 Change-Id: I429e5ce5efa94e01e7489deb3996012cf860cf13 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2220765 Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Reviewed-by: Tobias Tebbi <tebbi@chromium.org> Cr-Commit-Position: refs/heads/master@{#69008}

[offthread] Change OffThreadIsolate to LocalIsolate This patch introduces a new LocalIsolate and LocalFactory, which use LocalHeap and replace OffThreadIsolate and OffThreadFactory. This allows us to remove those classes, as well as the related OffThreadSpace, OffThreadLargeObjectSpace, OffThreadHeap, and OffThreadTransferHandle. OffThreadLogger becomes LocalLogger. LocalHeap behaves more like Heap than OffThreadHeap did, so this allows us to additionally remove the concept of "Finish" and "Publish" that the OffThreadIsolate had, and allows us to internalize strings directly with the newly-concurrent string table (where the implementation can now move to FactoryBase). This patch also removes the off-thread support from the deserializer entirely, as well as removing the LocalIsolateWrapper which allowed run-time distinction between Isolate and OffThreadIsolate. LocalHeap doesn't support the reservation model used by the deserializer, and we will likely move the deserializer to use LocalIsolate unconditionally once we figure out the details of how to do this.

Reland "[heap] Skip ro-space from heap iterators, add CombinedHeapIterator." Code relocation info is now always allocated in old-space. Before relocation info allocated for placeholders and builtins (which get replaced with trampolines in nosnap builds) would become unreachable. Since read-only space is not GCed and ReadOnlyHeapIterator doesn't check for reachability, ValidateSnapshot would fail finding unreachable objects returned by ReadOnlyHeapIterator. Because trampoline relocation info gets replaced with canonical one, this only affects no-embdded-builtins nosnap builds, which don't get much benefit from read-only relocation info anyway. A new check has been added to the read-only deserializer to verify that every read-only object is reachable at mksnapshot-time. The CombinedHeapIterator iteration order was changed to iterate over read-only space first, because that's how HeapIterator worked.

Reland "cppgc-js: Add snapshot for C++ objects" This reverts commit fba14bde5fa0ac26ee6732677acbc3f21e135c74. Reland fixes: - const vector<const string> -> const vector<string> Original message: The following implements a snapshotting algorithm for C++ objects that also filters strongly-connected components (SCCs) of only "hidden" objects that are not (transitively) referencing any non-hidden objects. C++ objects come in two versions. a. Named objects that have been assigned a name through NameProvider. b. Unnamed objects, that are potentially hidden if the build configuration requires Oilpan to hide such names. Hidden objects have their name set to NameProvider::kHiddenName. The main challenge for the algorithm is to avoid blowing up the final object graph with hidden nodes that do not carry information. For that reason, the algorithm filters SCCs of only hidden objects, e.g.: ... -> (object) -> (object) -> (hidden) -> (hidden) In this case the (hidden) objects are filtered from the graph. The trickiest part is maintaining visibility state for objects referencing other objects that are currently being processed. Main algorithm idea (two passes): 1. First pass marks all non-hidden objects and those that transitively reach non-hidden objects as visible. Details: - Iterate over all objects. - If object is non-hidden mark it as visible and also mark parent as visible if needed. - If object is hidden, traverse children as DFS to find non-hidden objects. Post-order process the objects and mark those objects as visible that have child nodes that are visible themselves. - Maintain an epoch counter (StateStorage::state_count_) to allow deferring the visibility decision to other objects in the same SCC. This is similar to the "lowlink" value in Tarjan's algorithm for SCC. - After the first pass it is guaranteed that all deferred visibility decisions can be resolved. 2. Second pass adds nodes and edges for all visible objects. - Upon first checking the visibility state of an object, all deferred visibility states are resolved. For practical reasons, the recursion is transformed into an iteration. We do not use plain Tarjan's algorithm to avoid another pass over all nodes to create SCCs. Follow ups: 1. Adding wrapper nodes for cpp objects that are wrappables for V8 wrappers. 2. Adding detachedness information.

[offthread] Add OffThreadFactory Introduce OffThreadFactory with initial string construction support. The OffThreadFactory shares with Factory a new CRTP base class, called FactoryBase. Methods in FactoryBase return a FactoryHandle<Factory, T> alias, which is Handle<T> for normal Factory and a new OffThreadHandle<T> for OffThreadFactory. OffThreadHandle<T> behaves like Handle<T>, except it stores the object in-line rather than needing external storage. Any shared factory methods are moved into FactoryBase, which uses CRTP to call the sub-class's AllocateRaw method (plus a few more customization points which need Isolate access on the main thread). Methods that used to take an Isolate or Factory, and are needed off the main thread, are now expected to be templated on the factory type and to use the appropriate handle. Once an OffThreadFactory has finished being used (e.g. off-thread compilation completed) its pages are "Published" into the main-thread Heap. To deal with string internalization without creating a bunch of ThinStrings, this is done in two stages: 1. 'FinishOffThread': The off-thread pages are walked to collect all slots pointing to "internalized" strings. After this is called it is invalid to allocate any more objects with the factory. 2. 'Publish': On the main thread, we transform these slots into <Handle to holder, offset> pairs, then for each saved slot re-internalize its string and update the slot to point to the internalized string.

[Interpreter] Optimize BytecodeArrayBuilder and BytecodeArrayWriter. This CL optimizes the code in BytecodeArrayBuilder and BytecodeArrayWriter by making the following main changes: - Move operand scale calculation out of BytecodeArrayWriter to the BytecodeNode constructor, where the decision on which operands are scalable can generally be statically decided by the compiler. - Move the maximum register calculation out of BytecodeArrayWriter and into BytecodeRegisterOptimizer (which is the only place outside BytecodeGenerator which updates which registers are used). This avoids the BytecodeArrayWriter needing to know the operand types of a node as it writes it. - Modify EmitBytecodes to use individual push_backs rather than building a buffer and calling insert, since this turns out to be faster. - Initialize BytecodeArrayWriter's bytecode vector by reserving 512 bytes, - Make common functions in Bytecodes constexpr so that they can be statically calculated by the compiler. - Move common functions and constructors in Bytecodes and BytecodeNode to the header so that they can be inlined. - Change large static switch statements in Bytecodes to const array lookups, and move to the header to allow inlining. I also took the opportunity to remove a number of unused helper functions, and rework some others for consistency. This reduces the percentage of time spent in making BytecodeArrays in CodeLoad from ~15% to ~11% according to perf. The CoadLoad score increase by around 2%.

This allows us to remove those classes, as well as the related OffThreadSpace, OffThreadLargeObjectSpace, OffThreadHeap, and OffThreadTransferHandle. OffThreadLogger becomes LocalLogger. LocalHeap behaves more like Heap than OffThreadHeap did, so this allows us to additionally remove the concept of "Finish" and "Publish" that the OffThreadIsolate had, and allows us to internalize strings directly with the newly-concurrent string table (where the implementation can now move to FactoryBase). This patch also removes the off-thread support from the deserializer entirely, as well as removing the LocalIsolateWrapper which allowed run-time distinction between Isolate and OffThreadIsolate. LocalHeap doesn't support the reservation model used by the deserializer, and we will likely move the deserializer to use LocalIsolate unconditionally once we figure out the details of how to do this.

[torque] generate C++ class definitions per Torque file This CL splits the class definitions per .tq file, to realize the following relationship: A class defined in src/objects/foo.tq has a C++ definition in src/objects/foo.h. Torque then generates: - torque-generated/src/objects/foo-tq.inc An include file (no proper header) to be included in src/objects/foo.h containing the Torque-generated C++ class definition. - torque-generated/src/objects/foo-tq-inl.inc An include file (no proper header) to be included in src/objects/foo-inl.h containing inline function definitions. - torque-generated/src/objects/foo-tq.cc A source file including src/objects/foo-inl.h that contains non-inline function definitions. Advantages of this approach: - Avoid big monolithic headers and preserve the work that went into splitting objects.h - Moving a definition to Torque keeps everything in the same place from a C++ viewpoint, including a fully Torque-generated C++ class definition. - The Torque-generated include files do not need to be independent headers, necessary includes or forward declarations can just be added to the headers that include them. Drive-by changes: A bunch of definitions and files had to be moved or created to realize a consistent 1:1 relationship between .tq files and C++ headers.

[torque] Generate instance types Design doc: https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit Changes from the design doc: - Changed to use 'class' declarations rather than 'type' declarations for things that need instance types but whose layout is not known to Torque. These declarations end with a semicolon rather than having a full set of methods and fields surrounded by {}. If the class's name should not be treated as a class name in generated output (because it's actually a template, or doesn't exist at all), we use the standard 'generates' clause to declare the most appropriate C++ class. - Removed @instanceTypeName. - @highestInstanceType became @highestInstanceTypeWithinParentClassRange to indicate a semantic change: it no longer denotes the highest instance type globally, but only within the range of values for its immediate parent class. This lets us use it for Oddball, which is expected to be the highest primitive type. - Added new abstract classes JSCustomElementsObject and JSSpecialObject to help with some range checks. - Added @lowestInstanceTypeWithinParentClassRange so we can move the new classes JSCustomElementsObject and JSSpecialObject to the beginning of the JSObject range. This seems like the least-brittle way to establish ranges that also include JSProxy (and these ranges are verified with static assertions in instance-type.h). - Renamed @instanceTypeValue to @apiExposedInstanceTypeValue. - Renamed @instanceTypeFlags to @reserveBitsInInstanceType. This change introduces the new annotations and adds the ability for Torque to assign instance types that satisfy those annotations. Torque now emits two new macros: - TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the InstanceType enumeration - TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String parts of INSTANCE_TYPE_LIST The design document mentions a couple of other macro lists that could easily be replaced, but I'd like to defer those to a subsequent checkin because this one is already pretty large.

[runtime] Move string table off-heap Changes the isolate's string table into an off-heap structure. This allows the string table to be resized without allocating on the V8 heap, and potentially triggering a GC. This allows existing strings to be inserted into the string table without requiring allocation. This has two important benefits: 1) It allows the deserializer to insert strings directly into the string table, rather than having to defer string insertion until deserialization completes. 2) It simplifies the concurrent string table lookup to allow resizing the table inside the write lock, therefore eliminating the race where two concurrent lookups could both resize the table. The off-heap string table has the following properties: 1) The general hashmap behaviour matches the HashTable, i.e. open addressing, power-of-two sized, quadratic probing. This could, of course, now be changed. 2) The empty and deleted sentinels are changed to Smi 0 and 1, respectively, to make those comparisons a bit cheaper and not require roots access. 3) When the HashTable is resized, the old elements array is kept alive in a linked list of previous arrays, so that concurrent lookups don't lose the data they're accessing. This linked list is cleared by the GC, as then we know that all threads are in a safepoint. 4) The GC treats the hash table entries as weak roots, and only walks them for non-live reference clearing and for evacuation. 5) Since there is no longer a FixedArray to serialize for the startup snapshot, there is now a custom serialization of the string table, and the string table root is considered unserializable during weak root iteration. As a bonus, the custom serialization is more efficient, as it skips non-string entries. As a drive-by, rename LookupStringExists_NoAllocate to TryStringToIndexOrLookupExisting, to make it clearer that it returns a non-string for the case when the string is an array index. As another drive-by, extract StringSet into a separate header.

[es2015] Introduce dedicated GetTemplateObject bytecode. Tagged templates were previously desugared during parsing using some combination of runtime support written in JavaScript and C++, which prevented some optimizations from happening, namely the constant folding of the template object in TurboFan optimized code. This CL adds a new bytecode GetTemplateObject (with a corresponding GetTemplateObject AST node), which represents the abstract operation in the ES6 specification and allows TurboFan to simply constant-fold template objects at compile time (which is explicitly supported by the specification). This also pays down some technical debt by removing the template.js runtime support and therefore should reduce the size of the native context (snapshot) a bit. With this change in-place the ES6 version microbenchmark in the referenced tracking bug is now faster than the transpiled Babel code, it goes from templateStringTagES5: 4552 ms. templateStringTagES6: 14185 ms. templateStringTagBabel: 7626 ms. to templateStringTagES5: 4515 ms. templateStringTagES6: 7491 ms. templateStringTagBabel: 7639 ms. which corresponds to a solid 45% reduction in execution time. With some further optimizations the ES6 version should be able to outperform the ES5 version. This micro-benchmark should be fairly representative of the six-speed-templatestringtag-es6 benchmark, and as such that benchmark should also improve by around 50%.

[torque] generate C++ class definitions per Torque file This CL splits the class definitions per .tq file, to realize the following relationship: A class defined in src/objects/foo.tq has a C++ definition in src/objects/foo.h. Torque then generates: - torque-generated/src/objects/foo-tq.inc An include file (no proper header) to be included in src/objects/foo.h containing the Torque-generated C++ class definition. - torque-generated/src/objects/foo-tq-inl.inc An include file (no proper header) to be included in src/objects/foo-inl.h containing inline function definitions. - torque-generated/src/objects/foo-tq.cc A source file including src/objects/foo-inl.h that contains non-inline function definitions. Advantages of this approach: - Avoid big monolithic headers and preserve the work that went into splitting objects.h - Moving a definition to Torque keeps everything in the same place from a C++ viewpoint, including a fully Torque-generated C++ class definition. - The Torque-generated include files do not need to be independent headers, necessary includes or forward declarations can just be added to the headers that include them. Drive-by changes: A bunch of definitions and files had to be moved or created to realize a consistent 1:1 relationship between .tq files and C++ headers.

[parser] Replacing ExpressionClassifier with ExpressionScope that knows what it's tracking Since it's explicit what we're tracking, we can immediately throw errors in certain cases, and ignore irrelevant errors. We don't need to use the classifier itself to track "let let", since we know whether we're parsing a "let". Errors that were previously (almost) always accumulated are now immediately pushed to the scopes that care (parameter initialization errors). This CL drops avoiding allocation of classified errors, at least for now, but that doesn't affect performance anymore since we don't aggressively blacklist anymore. Classified errors are even less likely with the more precise approach. ParseAssignmentExpression doesn't introduce its own scope immediately, but reuses the outer scope. Rather than using full ExpressionClassifiers + Accumulate to separate expressions/patterns from each other while keeping track of the overall error state, this now uses an explicit AccumulationScope. When we parse (async) arrow functions we introduce new scopes that track that they may be (async) arrow functions. We track StrictModeFormal parameters in 2 different ways if it isn't immediately certain that it is a strict-mode formal error: Either directly on the (Pre)ParserFormalParameters, or on the NextArrowFunctionInfo in the case we're not yet certain that we'll have an arrow function. In the latter case we don't have a FormalParameter object yet, and we'll copy it over once we know we're parsing an arrow function. The latter works because it's not allowed to change strictness of a function with non-simple parameters.

Sort import assertions by code point order of the keys Per https://tc39.es/proposal-import-assertions/#sec-assert-clause-to-assertions, import assertions should be sorted by the import assertion [[Key]]s, in order to prevent hosts from relying on a changing order of the assertions to determine behavior. Prior to this change, the assertions were being sorted by pointer. With this CL, the keys are sorted using a code point ordering so that the order of the assertions received by the host will be stable and non-surprising. This CL also switches the SourceTextModuleDescriptor's ModuleRequestMap, RegularExportMap, and RegularImportMap to use the code point order comparison rather than their former shortlex sort. This change will not be externally visible, but it seems best to make these consistent. In order to avoid #including the fairly large ast-value-factory.h into ast/modules.h, I changed ImportAssertions into a separate class definition rather than keeping it as a typedef. The alternative would be to define a common AstRawStringComparer in ast-value-factory.h and then #include ast-value-factory.h in both ast/modules.h and parsing/parser.h so that the ImportAssertions typedef would have a full, shared definition of the AstRawStringComparer type.

Implement DFA Unicode Decoder This is a separation of the DFA Unicode Decoder from https://chromium-review.googlesource.com/c/v8/v8/+/789560 I attempted to make the DFA's table a bit more explicit in this CL. Still, the linter prevents me from letting me present the array as a "table" in source code. For a better representation, please refer to https://docs.google.com/spreadsheets/d/1L9STtkmWs-A7HdK5ZmZ-wPZ_VBjQ3-Jj_xN9c6_hLKA - - - - - Now for a big copy-paste from 789560: Essentially, reworks a standard FSM (imagine an array of structs) and flattens it out into a single-dimension array. Using Table 3-7 of the Unicode 10.0.0 standard (page 126 of http://www.unicode.org/versions/Unicode10.0.0/ch03.pdf), we can nicely map all bytes into one of 12 character classes: 00. 0x00-0x7F 01. 0x80-0x8F (split from general continuation because this range is not valid after a 0xF0 leading byte) 02. 0x90-0x9F (split from general continuation because this range is not valid after a 0xE0 nor a 0xF4 leading byte) 03. 0xA0-0xBF (the rest of the continuation range) 04. 0xC0-0xC1, 0xF5-0xFF (the joined range of invalid bytes, notice this includes 255 which we use as a known bad byte during hex-to-int decoding) 05. 0xC2-0xDF (leading bytes which require any continuation byte afterwards) 06. 0xE0 (leading byte which requires a 0xA0-0xBF afterwards then any continuation byte after that) 07. 0xE1-0xEC, 0xEE-0xEF (leading bytes which requires any continuation afterwards then any continuation byte after that) 08. 0xED (leading byte which requires a 0x80-0x9F afterwards then any continuation byte after that) 09. 0xF1-F3 (leading bytes which requires any continuation byte afterwards then any continuation byte then any continuation byte) 10. 0xF0 (leading bytes which requires a 0x90-0xBF afterwards then any continuation byte then any continuation byte) 11. 0xF4 (leading bytes which requires a 0x80-0x8F afterwards then any continuation byte then any continuation byte) Note that 0xF0 and 0xF1-0xF3 were swapped so that fewer bytes were needed to represent the transition state ("9, 10, 10, 10" vs. "10, 9, 9, 9"). Using these 12 classes as "transitions", we can map from one state to the next. Each state is defined as some multiple of 12, so that we're always starting at the 0th column of each row of the FSM. From each state, we add the transition and get a index of the new row the FSM is entering. If at any point we encounter a bad byte, the state + bad-byte-transition is guaranteed to map us into the first row of the FSM (which contains no valid exiting transitions). The key differences from Björn's original (or his self-modified) DFA is the "bad" state is now mapped to 0 (or the first row of the FSM) instead of 12 (the second row). This saves ~50 bytes when gzipping, and also speeds up determining if a string is properly encoded (see his sample code at http://bjoern.hoehrmann.de/utf-8/decoder/dfa/#performance). Finally, I've replace his ternary check with an array access, to make the algorithm branchless. This places a requirement on the caller to 0 out the code point between successful decodings, which it could always have done because it's already branching.

[wasm] Initial signal handler This is basically the minimum viable signal handler for Wasm bounds checks. It includes the TLS check and the fine grained instructions checks. These two checks provide most of the safety for the signal handler. Future CLs will add code range and data range checks for more robustness. The trap handling code and data structures are all in src/trap-handler, with the code that actually runs in the signal handler confined to src/trap-handler/signal-handler.cc. This changes adds a new V8 API that the embedder should call from a signal handler that will give V8 the chance to handle the fault first. For hosts that do not want to implement their own signal handler, we include the option to install a simple one. This simple handler is also used for the tests. When a Wasm module is instantiated, information about each function is passed to the trap handler, which is used to classify faults. These are removed during the instance finalizer. Several future enhancements are planned before turning this on by default. Obviously, the additional checks will be added to MaybeHandleFault. We are also planning to add a two-level CodeObjectData table that is grouped by isolates to make cleanup easier and also reduce potential for contending on a single data structure.

Reland "[arm64] Protect return addresses stored on stack" This is a reland of 137bfe47c9af56dcf8466e2736579616e51b86df Original change's description: > [arm64] Protect return addresses stored on stack > > This change uses the Arm v8.3 pointer authentication instructions in > order to protect return addresses stored on the stack. The generated > code signs the return address before storing on the stack and > authenticates it after loading it. This also changes the stack frame > iterator in order to authenticate stored return addresses and re-sign > them when needed, as well as the deoptimizer in order to sign saved > return addresses when creating new frames. This offers a level of > protection against ROP attacks. > > This functionality is enabled with the v8_control_flow_integrity flag > that this CL introduces. > > The code size effect of this change is small for Octane (up to 2% in > some cases but mostly much lower) and negligible for larger benchmarks, > however code size measurements are rather noisy. The performance impact > on current cores (where the instructions are NOPs) is single digit, > around 1-2% for ARES-6 and Octane, and tends to be smaller for big > cores than for little cores. > > Bug: v8:10026 > Change-Id: I0081f3938c56e2f24d8227e4640032749f4f8368 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1373782 > Commit-Queue: Georgia Kouveli <georgia.kouveli@arm.com> > Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Cr-Commit-Position: refs/heads/master@{#66239} Bug: v8:10026 Change-Id: Id1adfa2e6c713f6977d69aa467986e48fe67b3c2 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2051958 Reviewed-by: Georg Neis <neis@chromium.org> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Commit-Queue: Georgia Kouveli <georgia.kouveli@arm.com> Cr-Commit-Position: refs/heads/master@{#66254}

[heap] Add object start bitmap for conservative stack scanning With conservative stack scanning enabled, a snapshot of the call stack upon entry to GC will be used to determine part of the root-set. When the collector walks the stack, it looks at each value and determines whether it could be a potential on-heap object pointer. However, unlike with Handles, these on-stack pointers aren't guaranteed to point to the start of the object: the compiler may decide hide these pointers, and create interior pointers in C++ frames which the GC doesn't know about. The solution to this is to include an object start bitmap in the header of each page. Each bit in the bitmap represents a word in the page payload which is set when an object is allocated. This means that when the collector finds an arbitrary potential pointer into the page, it can walk backwards through the bitmap until it finds the relevant object's base pointer. To prevent the bitmap becoming stale after compaction, it is rebuilt during object sweeping. This is experimental, and currently only works with inline allocation disabled, and single generational collection.

Add initial support for Wasm debugging with LLDB: implements a GDB-remote stub This is the first piece of the wasm debugging prototype (besides the changes to add/remove breakpoints in WasmModuleObject made with https://chromium.googlesource.com/v8/v8.git/+/e699f39caed9a23f8e20bd3a0386a3236e272737). This changelist adds the infrastructure for a GDB-remote stub that will be used to manage debugging sessions via the gdb-remote protocol. It enables the creation and termination of debugging sessions over TCP connections that are managed in a separate thread.

[wasm] Initial signal handler This is basically the minimum viable signal handler for Wasm bounds checks. It includes the TLS check and the fine grained instructions checks. These two checks provide most of the safety for the signal handler. Future CLs will add code range and data range checks for more robustness. The trap handling code and data structures are all in src/trap-handler, with the code that actually runs in the signal handler confined to src/trap-handler/signal-handler.cc. This changes adds a new V8 API that the embedder should call from a signal handler that will give V8 the chance to handle the fault first. For hosts that do not want to implement their own signal handler, we include the option to install a simple one. This simple handler is also used for the tests. When a Wasm module is instantiated, information about each function is passed to the trap handler, which is used to classify faults. These are removed during the instance finalizer. Several future enhancements are planned before turning this on by default. Obviously, the additional checks will be added to MaybeHandleFault. We are also planning to add a two-level CodeObjectData table that is grouped by isolates to make cleanup easier and also reduce potential for contending on a single data structure.

Reland "[arm64] Protect return addresses stored on stack" This is a reland of 137bfe47c9af56dcf8466e2736579616e51b86df Original change's description: > [arm64] Protect return addresses stored on stack > > This change uses the Arm v8.3 pointer authentication instructions in > order to protect return addresses stored on the stack. The generated > code signs the return address before storing on the stack and > authenticates it after loading it. This also changes the stack frame > iterator in order to authenticate stored return addresses and re-sign > them when needed, as well as the deoptimizer in order to sign saved > return addresses when creating new frames. This offers a level of > protection against ROP attacks. > > This functionality is enabled with the v8_control_flow_integrity flag > that this CL introduces. > > The code size effect of this change is small for Octane (up to 2% in > some cases but mostly much lower) and negligible for larger benchmarks, > however code size measurements are rather noisy. The performance impact > on current cores (where the instructions are NOPs) is single digit, > around 1-2% for ARES-6 and Octane, and tends to be smaller for big > cores than for little cores. > > Bug: v8:10026 > Change-Id: I0081f3938c56e2f24d8227e4640032749f4f8368 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1373782 > Commit-Queue: Georgia Kouveli <georgia.kouveli@arm.com> > Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Cr-Commit-Position: refs/heads/master@{#66239} Bug: v8:10026 Change-Id: Id1adfa2e6c713f6977d69aa467986e48fe67b3c2 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2051958 Reviewed-by: Georg Neis <neis@chromium.org> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Commit-Queue: Georgia Kouveli <georgia.kouveli@arm.com> Cr-Commit-Position: refs/heads/master@{#66254}

Unwind V8 frames correctly on Windows ARM64 On Windows ARM64, OS stack walking does not work because the V8 ARM64 backend doesn't emit unwinding info and also because it doesn't emit ABI compliant stack frames. This was fixed for Windows X64 (https://crrev.com/c/1469329) and documented below: https://docs.google.com/document/d/1-wf50jFlii0c_Pr52lm2ZU-49m220nhYMrHDi3vXnh0 This problem can be fixed similarly for Windows ARM64 by observing that V8 frames usually all have the same prolog which maintains a chain via frame pointer (fp or x29 register). stp fp, lr, [sp, ...] One exception is JSEntry which stops fp pointer chain and needs to be handled specially. So it is possible to define XDATA with UNWIND_CODE which specify how Windows should walk through V8 dynamic frames. The same as X64, since V8 Code objects are all allocated in the same code-range for an Isolate, it is possible to register at most 2 XDATA and a group of PDATA entries to cover stack walking for all the code generated inside that code-range. This is more than 1 PDATA/XDATA because according to the Windows ARM64 exeption handling document, 1 PDATA can cover less than 1MB code range (see below doc). https://docs.microsoft.com/en-us/cpp/build/arm64-exception-handling This PR implements stackwalk for Windows ARM64 to be on par with X64, including embedded builtins, jitted code and wasm jitted code, but not including register handler for handling exception only, because there is no backward compatibility to maintain for Windows ARM64 which was released since 1709 windows build.

Reland "Add postmortem debugging helper library" This is a reland of 517ab73fd7e3fdb70220b9699bca4c69a32e212e Updates since original: now compressed pointers passed to the function GetObjectProperties are required to be sign-extended. Previously, the function allowed zero-extended values, but that led to ambiguity on pointers like 0x88044919: is it compressed or is the heap range actually centered on 0x100000000? Original change's description: > Add postmortem debugging helper library > > This change begins to implement the functionality described in > https://docs.google.com/document/d/1evHnb1uLlSbvHAAsmOXyc25x3uh1DjgNa8u1RHvwVhk/edit# > for investigating V8 state in crash dumps. > > This change adds a new library, v8_debug_helper, for providing platform- > agnostic assistance with postmortem debugging. This library can be used > by extensions built for debuggers such as WinDbg or lldb. Its public API > is described by debug-helper.h; currently the only method it exposes is > GetObjectProperties, but we'd like to add more functionality over time. > The API surface is restricted to plain C-style structs and pointers, so > that it's easy to link from a debugger extension built with a different > toolchain. > > This change also adds a new cctest file to exercise some basic > interaction with the new library. > > The API function GetObjectProperties takes an object pointer (which > could be compressed, or weak, or a SMI), and returns a string > description of the object and a list of properties the object contains. > For now, the list of properties is entirely based on Torque object > definitions, but we expect to add custom properties in future updates so > that it can be easier to make sense of complex data structures such as > dictionaries. > > GetObjectProperties does several things that are intended to generate > somewhat useful results even in cases where memory may be corrupt or > unavailable: > - The caller may optionally provide a type string which will be used if > the memory for the object's Map is inaccessible. > - All object pointers are compared against the list of known objects > generated by mkgrokdump.

[torque] Generate instance types Design doc: https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit Changes from the design doc: - Changed to use 'class' declarations rather than 'type' declarations for things that need instance types but whose layout is not known to Torque. These declarations end with a semicolon rather than having a full set of methods and fields surrounded by {}. If the class's name should not be treated as a class name in generated output (because it's actually a template, or doesn't exist at all), we use the standard 'generates' clause to declare the most appropriate C++ class. - Removed @instanceTypeName. - @highestInstanceType became @highestInstanceTypeWithinParentClassRange to indicate a semantic change: it no longer denotes the highest instance type globally, but only within the range of values for its immediate parent class. This lets us use it for Oddball, which is expected to be the highest primitive type. - Added new abstract classes JSCustomElementsObject and JSSpecialObject to help with some range checks. - Added @lowestInstanceTypeWithinParentClassRange so we can move the new classes JSCustomElementsObject and JSSpecialObject to the beginning of the JSObject range. This seems like the least-brittle way to establish ranges that also include JSProxy (and these ranges are verified with static assertions in instance-type.h). - Renamed @instanceTypeValue to @apiExposedInstanceTypeValue. - Renamed @instanceTypeFlags to @reserveBitsInInstanceType. This change introduces the new annotations and adds the ability for Torque to assign instance types that satisfy those annotations. Torque now emits two new macros: - TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the InstanceType enumeration - TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String parts of INSTANCE_TYPE_LIST The design document mentions a couple of other macro lists that could easily be replaced, but I'd like to defer those to a subsequent checkin because this one is already pretty large.

[tracing] Add a way to test perfetto traces. Add a new abstract class TraceEventListener which is just an interface for consuming trace events. This separates the V8-specific stuff that an actual perfetto consumer needs to do e.g. handling the has_more flag and signalling back to the controller with a semaphore. This is a change from the previous plan of making the PerfettoConsumer class sub-classable to implement custom consumption of trace events. This will be difficult when the consumer is created outside of the PerfettoTracingController as we can't hook up the consumer_finished_semaphore_ that belongs to the controller. Now the PerfettoTracingController is responsible for the Consumer life- cycle and hides it entirely from callers. We add the AddTraceEventListener() method to allow callers to register a listener either for testing or a JSON listener for real tracing. This lets us write tests that can store all the trace events in memory without first converting them to JSON, letting us write test more easily. There's an example test add to test-tracing - more tests using this style will follow.

Reland "Reland "cppgc, heap: Don't eagerly allocate worklist segments"" This is a reland of f25cb50a2fc5f51d7bd70e885fb7e6e4123d77dc Removed the problematic tests. The problem with the test was that we try to pop from an empty segment. GCC flags that as accessing beyond the array (i.e. index is uint16_t equivalent of -1). Preceding the actual pop is a DCHECK that asserts the segment isn't empty. In practice, since we have the DCHECK and access to the segment is always via a Local, this shouldn't be a problem. Unfortunately, GCC flags the access regardless. The DCHECK goes through a function pointer so GCC cannot determine that in our unittest the DCHECK would crash if index is 0 and the access would not happen (The indirection was added to allow for test DCHECK handlers that don't crash, so we can't mark the function pointer as noreturn). Drive-by: Segment::Pop and Segment::Push rely on the their Local counterparts checking of emptiness/fullness, so we should always access segments via Locals. Making the Segment ctor private.

[embedded handlers] Store the handlers without gaps Previously the builtins table had a value for every single OperandScale/Bytecode combination regardless of whether it was valid. This change makes it so that only valid bytecode handlers are stored in the builtins table. This prevents placeholders being serialized into the snapshot (and embedded into the binary) saving 9KB in CODE_SPACE/OLD_SPACE and 2.5KB in the embedded data as well as 66 entries in the builtins table. To do this, it generates a new header file bytecodes-builtins-list.h which is created from the BYTECODE_LIST and OPERAND_SCALE_LIST macros. Since list macros cannot be used to conditionally generate elements in the C-preprocessor, this is done by generator executable, compiled from interpreter/generate-flat-headers.cc. Additionally the generator creates the flat bytecode list so that it is transposed from the previous result, i.e. the results are grouped by bytecode and then operand scale rather than operand scale then bytecode. This should give better locality for commonly used bytecodes and may allow less commonly used ExtraWide bytecodes to never be mapped into memory at all. The cost to storing the handlers densely is that looking up a handler now requires a binary search through the builtins table, but this should only happen during debugging. It is also fixable at least for non-wide handlers and could be improved for wide ones if the need arises.

[embedded handlers] Store the handlers without gaps Previously the builtins table had a value for every single OperandScale/Bytecode combination regardless of whether it was valid. This change makes it so that only valid bytecode handlers are stored in the builtins table. This prevents placeholders being serialized into the snapshot (and embedded into the binary) saving 9KB in CODE_SPACE/OLD_SPACE and 2.5KB in the embedded data as well as 66 entries in the builtins table. To do this, it generates a new header file bytecodes-builtins-list.h which is created from the BYTECODE_LIST and OPERAND_SCALE_LIST macros. Since list macros cannot be used to conditionally generate elements in the C-preprocessor, this is done by generator executable, compiled from interpreter/generate-flat-headers.cc. Additionally the generator creates the flat bytecode list so that it is transposed from the previous result, i.e. the results are grouped by bytecode and then operand scale rather than operand scale then bytecode. This should give better locality for commonly used bytecodes and may allow less commonly used ExtraWide bytecodes to never be mapped into memory at all. The cost to storing the handlers densely is that looking up a handler now requires a binary search through the builtins table, but this should only happen during debugging. It is also fixable at least for non-wide handlers and could be improved for wide ones if the need arises.

[wasm] Syntax- and Type-aware Fuzzer This is the beginning of a new fuzzer that generates correct-by-construction Wasm modules. This should allow us to better exercise the compiler and correctness aspects of fuzzing. It is based off of ahaas' original Wasm fuzzer. At the moment, it can generate expressions made up of most binops, and also nested blocks with unconditional breaks. Future CLs will add additional constructs, such as br_if, loops, memory access, etc. The way the fuzzer works is that it starts with an array of arbitrary data provided by libfuzzer. It uses the data to generate an expression. Care is taken to make use of the entire string. Basically, the generator has a bunch of grammar-like rules for how to construct an expression of a given type. For example, an i32 can be made by adding two other i32s, or by wrapping an i64. The process then continues recursively until all the data is consumed. We generate an expression from a slice of data as follows: * If the slice is less than or equal to the size of the type (e.g. 4 bytes for i32), then it will emit the entire slice as a constant. * Otherwise, it will consume the first 4 bytes of the slice and use this to select which rule to apply. Each rule then consumes the remainder of the slice in an appropriate way. For example: * Unary ops use the remainder of the slice to generate the argument. * Binary ops consume another four bytes and mod this with the length of the remaining slice to split the slice into two parts. Each of these subslices are then used to generate one of the arguments to the binop. * Blocks are basically like a unary op, but a stack of block types is maintained to facilitate branches. For blocks that end in a break, the first four bytes of a slice are used to select the break depth and the stack determines what type of expression to generate. The goal is that once this generator is complete, it will provide a one to one mapping between binary strings and valid Wasm modules.
