sgjesse@chromium.org	44b7c59eb5	Extend the maximum size map space On 32-bit the maps are now aligned on a 32-byte boundary in order to encode more maps during compacting GC. The actual size of a map on 32-bit is 28 bytes making this change waste 4 bytes per map. On 64-bit the encoding for compacting GC is now using more than 32-bits and the maps here are still pointer size aligned. The actual size of a map on 64-bit is 48 bytes and this change does not intruduce any waste. My choice of 16 bits for kMapPageIndexBits for 64-bit should give the same maximum number of pages (8K) for map space. As maps on 64-bit are larger than on 32-bit the total number of maps on 64-bit will be smaller than on 32-bit. We could consider raising this to 17 or 18. I moved the kPageSizeBits to globals.h as the calculation of the encoding really depended on this. There are still an #ifdef/#endif in objects.h and this constant could be moved to globaks.h as well, but I kept it together with the related constants. All the tests run in debug mode with additional options --gc-global --always-compact as well (except for a few tests on which also fails before this change when run with --gc-global --always-compact).

kmillikin@chromium.org	0672938b88	Fix a crash caused by garbage collection during generation of a callback load (or keyed load) IC. The problem was that the IC code calls a stub, which can allocate and thus trigger a GC if the stub is not already generated. Problem is solved by adding the ability to "try" to call a stub, trying to generate the stub code if necessary but signaling an allocation failure if generating the code is not possible.

sgjesse@chromium.org	fc713930ed	Remove the last context dependent reference from the Script object For scripts originating from a call to eval the Script object used to hold a reference to the function from where the eval was called together with the code offset within that function of the eval call. This is used by the stack trace and is part of the debugger protocol. In order to avoid storing the function the script, the position within the script and the name of the function calling eval is stored instead. This avoids holding context dependent objects in the script object. The calculation of the position of the eval in the script holding the eval is now done when the eval script is compiled as it is not possible to postpone this unless a reference is kept to the generated code for the function calling eval.

fschneider@chromium.org	d9d18b30f5	Implement IS_OBJECT and IS_FUNCTION as inlined runtime functions. Summary: This change fixes a performance regression introduced by the special handling of regular expressions in typeof expressions. As a result we regain ~8% speedup on 3d-raytrace and ~13% on boyer (vs bleeding edge) Description: The macros IS_OBJECT and IS_FUNCTION are frequently used in the JS runtime functions. By introducing new inlined runtime functions %_IsFunction and %_IsObject we avoid invoking the more expensive %_ClassOf function plus comparing its result to a string.

fschneider@chromium.org	53bee811ad	Re-enable using push instructions for syncing the virtual frame. This change fixes the problem with the original version of this approach (r3032) that may lead to a corrupted stack if we would invoke spilling during syncing a large SMI constant (unsafe SMIs) in the virtual frame. The new code for storing unsafe SMI constants does not use an extra temporary register. This prevents the compiler from ever having to spill during a virutal frame sync operation. For storing a large SMI constant we previously generated: mov ecx, (large_smi & 0x0000ffff) xor ecx, (large_smi & 0xffff0000) push ecx we now generate: push (large_smi & 0x0000ffff) or [esp], (large_smi & 0xffff0000) Not using a temporary register avoids spilling within an nvocation of VirtualFrame::SyncRange.

sgjesse@chromium.org	41d6cae46d	Fix issue 493: Infinite loop when debug break is set when entering function.apply. In the generated code for function.apply there was a loop checking the stack limit for interruption. This loop would call into the runtime system to handle interuption and keep running until there was no interruption. However if the interuption was debug break the runtime system would never clear the interruption as debug break is prevented in builtins are prevented and the assumption here was that returning with the debug break flag set would move execution forward. Renamed initial_jslimit and initial_climit to real_jslimit and real_climit. Renamed a few external references related to the stack limit as well. Exposed the real stack limit to generated code to make the stack check when entering function.apply use the real stack limit and not the stack limit which is changed to signal interruption. Added the real stack limit to the roots array.

In exception handling, we need to be able to compare addresses into the JavaScript portion of the stack with the address of a C++ handler on the stack. Since the stacks are separate on the simulator, we need a JavaScript stack address corresponding to a C++ try catch handler in order to perform valid address comparisons. On the simulator, we now link the C++ try catch handlers indirectly through the JS stack and use the JS stack indirection address for comparisons. JS C++ handler [C++ address] <------ next_ \ \ \----> handler [C++ address] <------ next_ On actual hardware the C++ try catch handlers continue to be directly linked.

kmillikin@chromium.org	ab3e85eeb4	Initial implementation of top-level compilation of expressions in test context. Test contexts are used for the left subexpressions of short-circuited boolean operators. The right subexpressions inherit their expression context from the binary op expression. Compilation of short-circuited operations in effect and test context is straightforward: effect(e0 \|\| e1) = test(e0, L0, L1) L1: effect(e1) L0: test(e0 \|\| e1, L0, L1) = test(e0, L0, L2) L2: test(e1, L0, L1) Because the value of the first subexpression may be needed as the value of the whole expression in a value context, we introduce a hybrid value/test contest (the value is needed if true, but not if false). value(e0 \|\| e1) = value/test(e0, L0, L1) L1: value(e1) L0: The compilation of value/test and test/value (introduced by boolean AND) is: value/test(e0 \|\| e1, L0, L1) = value/test(e0, L0, L2) L2: value/test(e1, L0, L1) test/value(e0 \|\| e1, L0, L1) = test(e0, L0, L2) L2: test/value(e1, L0, L1) Boolean AND is the dual. The AST nodes themselves (not their parents) are responsible for producing the proper result (effect, value, or control flow) depending on their context.

kmillikin@chromium.org	6a83cb0ced	In the toplevel compiler, shift the responsibility of assigning a location to an Expression AST node from the node's parent to the node itself. This allows an inherited code generation context from a parent node to be passed arbitrarily far down the tree (eg, the subexpression of a unary not is in the same context as the unary expression itself, the then and else subexpressions of the ternary operator are in the same context as the whole expression, and so forth). We do not yet take advantage of this in the backend (eg, the right subexpression of short-circuited OR is still compiled by using the parent's destination location, rather than the subexpression's itself).

kmillikin@chromium.org	76e1e22f15	Eliminate the constant location used for literals in the AST. Literals now have a location of temporary by default and are responsible for moving themselves into their location like all other expressions. The constant location turned out not to allow us to avoid checking subexpressions in AST interior nodes, and it turned out to require checking after some normal calls to Visit (like for the arguments to a call). With this change do not have to check after a call to Visit that we got our result in the expected location.

kmillikin@chromium.org	e82a07c0bd	Simple toplevel code generator support for short-circuited boolean OR in a non-test (ie, value or effect) context. (It is implicitly not in a test context because the code generator does not support expressions in a test context yet.) Compilation is essentially the same as in the optimized code generator. The expression (e0 \|\| e1) is compiled as if it were (let (temp = e0) temp ? temp : e1). On ia32 and x64 a single shared ToBoolean stub is used to convert a value to a flag. The inlined checks assumed by the stub are reordered to compare to undefined (the common case in toplevel code?) first. On ARM a call to the runtime is used.

kbr@chromium.org	46e6297e3e	Added infrastructure for optimizing new CanvasArray types in WebGL specification under development. The optimizations are patterned after those previously done for CanvasPixelArray. This CL adds all of the necessary framework but continues to use the generic KeyedLoadIC and KeyedStoreIC code, to create a baseline for benchmarking purposes. The next CL will add the optimized ICs to ic-ia32.cc and ic-x64.cc. These new CanvasArray types have different semantics than CanvasPixelArray; out-of-range values are clamped via C cast semantics, which is cheaper than the clamping behavior specified by CanvasPixelArray. Out-of-range indices raise exceptions instead of being silently ignored. As part of this work, pulled FloatingPointHelper::AllocateHeapNumber up to MacroAssembler on ia32 and x64 platforms. Slightly refactored KeyedLoadIC and KeyedStoreIC. Fixed encoding for fistp_d on x64 and added a few more instructions that are needed for the new ICs. The test cases in test-api.cc have been verified by hand to exercise all of the generated code paths in the forthcoming specialized ICs.

kmillikin@chromium.org	846688f825	Recognize in the fast-mode code generator when a subexpression is a constant known at compile time. Do not ever use the stack to materialize (non-function-argument) constants. Currently, constants are only the non-materialized, non-function literals in the AST. It is a known issue that there is no test coverage for the cases of assigning a non-literal to a variable and returning a literal. Those code paths are unreachable and tests will be added when they become reachable. For the code '.result = true', we had previously on ia32: 27 push 0xf5c28161 ;; object: 0xf5c28161 <true> 32 pop [ebp+0xf4] Now: 27 mov eax,0xf5c26161 ;; object: 0xf5c26161 <true> 32 mov [ebp+0xf4],eax ======== We had previously on x64: 25 movq r10,0x7fb8c2f78199 ;; object: 0x7fb8c2f78199 <true> 35 push r10 37 pop [rbp-0x18] Now: 25 movq r10,0x7fb131386199 ;; object: 0x7fb131386199 <true> 35 movq [rbp-0x18],r10 The generated code for ARM did not include the extra memory traffic.

kmillikin@chromium.org	f74e723599	Initial infrastructure for fast compilation of top-level code. The fast code generator is optimized for compilation time and code size. Currently it is only implemented on IA32. It is potentially triggered for any code in the global scope (including code eval'd in the global scope). It performs a syntactic check and chooses to compile in fast mode if the AST contains only supported constructs and matches some other constraints. Initially supported constructs are * ExpressionStatement, * ReturnStatement, * VariableProxy (variable references) to parameters and stack-allocated locals, * Assignment with lhs a parameter or stack-allocated local, and * Literal This allows compilation of literals at the top level and not much else. All intermediate values are allocated to temporaries and the stack is used for all temporaries. The extra memory traffic is a known issue. The code generated for 'true' is: 0 push ebp 1 mov ebp,esp 3 push esi 4 push edi 5 push 0xf5cca135 ;; object: 0xf5cca135 <undefined> 10 cmp esp,[0x8277efc] 16 jnc 27 (0xf5cbbb1b) 22 call 0xf5cac960 ;; code: STUB, StackCheck, minor: 0 27 push 0xf5cca161 ;; object: 0xf5cca161 <true> 32 mov eax,[esp] 35 mov [ebp+0xf4],eax 38 pop eax 39 mov eax,[ebp+0xf4] 42 mov esp,ebp ;; js return 44 pop ebp 45 ret 0x4 48 mov eax,0xf5cca135 ;; object: 0xf5cca135 <undefined> 53 mov esp,ebp ;; js return 55 pop ebp 56 ret 0x4 Review URL: http://codereview.chromium.org/273050 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@3067 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2009-10-14 19:30:50 +00:00

kmillikin@chromium.org	586f94f292	Split the AST LoopStatement type into separate types for do/while, while, and for loops. Previously they were distinguished by a type field, which required runtime asserts to avoid invalid nodes (since not all loop types have the same internal structure). Now they C++ type system is used to require well-formed loop ASTs. Because they do not share compilation code, we had very large functions in the code generators that merely did a runtime dispatch to a specific implementation based on the type.

sgjesse@chromium.org	8105ae3106	Optimize calls to GenericBinaryStub. The calls to GenericBinaryStub can now pass the arguments in registers instead of on the stack. It is supported for ADD, SUB, MUL and DIV. The convention in GenericBinaryStub is not changed so the left operand is passed in edx and the right one in eax. When the stub contains smi code arguments are always passed on the stack as the smi code has to have left and right operands on eax and ebx, so moving from edx,eax to eax,ebx is not worth it and the smi code also trashes the registers so if arguments where passed in registers they would have to be saved on the stack anyway. Added flags to disable the use of certain Intel CPU features to make it easier to test different code paths.
