kmillikin@chromium.org	4d1b2b1d38	Change the Hydrogen representation of uses. Rather than representing a use as a pointer to an HValue and then searching for the specific (ambiguous) operand, we now represent a use as a pair of an HValue and the input operand index. Additionally, use a linked list instead of a growable array list since we never use random access. This allows us to remove a bunch of similarly named and subtly different functions from the HValue API. The cost in extra zone allocation per use is partially offset by reusing use list nodes when replacing a use of one value with another.

This is the first patch on the way to removing the classic code generator from the system. This time with no removal of the crankshaft flag. --nocrankshaft is not at all the same as --always-full-compiler which I had used instead for testing. That was what caused timeouts on the buildbots because of repeated attempts to optimize hot functions.

fschneider@chromium.org	8066271fd2	Optimize calls to object literal properties that are initialized with a function literal. This allows fast calls and inlining of functions like: var o = {f: function() { return "foo"; }} o.f(); Object literals that contain function literals are initially created a dictionary mode object and only transformed to fast properties once all properties are computed and added. This allows us to create constant function properties for functions declared inside the object literal.

fschneider@chromium.org	17da434b29	Remove instruction summaries. Instead of constructing a temporary container for all LOperands of each instruction, the register works directly on the LIR instructions that provide an abstract interface for input/output/temp operands. This saves allocation of zone memory and speeds up LIR construction, but makes iterating over all uses in the register allocator slightly more expensive because environment uses are stored in a linked list of environments. We can fix this by using a flat representation of LOperands.

kmillikin@chromium.org	f1149734fc	Partial fix for V8 issue 1079. Record a safepoint with a deoptimization id for throw in optimized code. We don't seem to much care what the AST ID is because we will not be using it for lazy deoptimization (throw doesn't return to the point of throw). For hygiene we use the actual ID of the throw expression. Throw is no longer a control-flow instruction, but it's followed by an unconditional abnormal exit. This is required to insert a simulate between the throw and the exit. Make our optimized treatment of Function.prototype.apply act like a call and have side effects. This ensures that it will get a lazy deoptimization environment. Use that deoptimization ID in the safepoint for the call. Deleting a property was also missing a deoptimization ID, though there was a deoptimization environment assigned to the instruction. Record the environment and use the deoptimization ID at the safepoint.

sgjesse@chromium.org	161d631b5e	Change ARM exit frame layout and alingment handling Change the ARM exit frame to have the same layout as the IA32 exit frame. This basically re-arranges the order of fp and sp and changes the sp location of the entry frame to hold the sp used by the gc and not the sp for popping the arguments. This removes the option of tearing down the frame and returning using one ldm instruction. The main motivation for this is to avoid pushing an alignment word before generating the entry frame. The GC handling of optimized frames process the registers pushed as part of a safepoint and asumes that these are at the top of the frame, so if an alignment word is pushed this processing will be one off. The alignment handling in the C entry stub have also been simplified. Now the value of lr is stored to a stack slot already reserved avoiding pushing it and keeping track of "frame skew". This does result in more instructions in the exit frame on ARM, but we can look into improving this later.

It returned the global context if the slot was not found or if it was found in a function's context or arguments object. This is not the correct object to use for 'delete'. Since this lookup function is only ever used when deleting LOOKUP slots (those that have to go through a with or a scope with eval), it is simply replaced with a Runtime_DeleteContextSlot function that does the appropriate thing for all kinds of context lookups. This fixes Chromium bug 70066. http://code.google.com/p/chromium/issues/detail?id=70066 Review URL: http://codereview.chromium.org/6280013 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@6442 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2011-01-24 14:03:30 +00:00

kbr@chromium.org	cbc1c0fca6	Truncate rather than round to nearest when performing float-to-integer conversions for external array types, which implement the Typed Array spec. (Revision of http://codereview.chromium.org/6315004 .) Prefer SSE2 code path on x86 processors. Non-SSE2 processors now make a slow runtime call for float-to-int conversions. Use SSE3 for 32-bit signed and unsigned int array types where possible. The movement of code from ic-arm.cc to stub-cache-arm.cc caused the VFP3 code path to be tested for the first time. Fixed bugs in the register usage and in the constant value stored into integer arrays for NaN and +/-Infinity. Added new truncation test to test-api.cc. Storage of NaN and +/-Inf was already covered. Ran unit tests on x86, x64 and ARM simulator. Tested ia32 and x64 code in Chromium on Mac and Linux respectively with Typed Array unit tests and WebGL content.

kmillikin@chromium.org	8a9eeaf8da	Reapply change to with/arguments interaction. This is svn r6415 with a bugfix. The bug was that we can have scopes with 0 heap slots (functions with such scopes do not need a local context) and scopes with at least Context::MIN_CONTEXT_SLOTS. The code generator only allocated a local context if there were strictly more than Context::MIN_CONTEXT_SLOTS. Before the change to with/arguments, it was impossible to actually get a function scope with exactly Context::MIN_CONTEXT_SLOTS because every such scope included a heap-allocated arguments (and arguments shadow) slot.

vitalyr@chromium.org	b4ff318e4b	Support StringCharCodeAt in hydrogen/lithium. This patch adds H- and L-variants of StringCharCodeAt and StringLength. StringCharCodeAt is used to inline a constant function call of String.prototype.charCodeAt and to implement the corresponding inline runtime function. It does not yet use the recently introduced extra IC state. (We can specialize on string encoding and avoid deopts because of out of bounds accesses.) StringLength needs more work because the stub version of it also supports strings wrappers and it matters in some cases. (We have to separate the string only case.)

kbr@chromium.org	27f0ae7aad	Truncate rather than round to nearest when performing float-to-integer conversions for external array types, which implement the Typed Array spec.

kmillikin@chromium.org	437914da90	Change the algorithm and generated code for parallel moves on IA32. Instead of spilling and then immediately restoring eax to resolve memory to memory moves, the gap move resolver now tracks registers that are known to be free and uses one if available. If not it spills but restores lazily when the spilled value is needed or at the end of the algorithm. Instead of using esi for resolving cycles and assuming it is free to overwrite because it can be rematerialized, the gap move resolver now resolves cycles using swaps, possibly using a free register as above. The algorithm is also changed to be simpler: a recursive depth-first traversal of the move dependence graph. It uses a list of moves to be performed (because it mutates the moves themselves), but does not use any auxiliary structure other than the control stack. It does not build up a separate list of scheduled moves to be interpreted by the code generate, but emits code on the fly.

kmillikin@chromium.org	ace6290452	Fix issue 974. When entering a finally block in unoptimized code, we unconditionally save the accumulator register in the stack in case it holds a return value or an exception. In the case of a break, continue, or falling off the end of the try or catch block, this value is unpredictable and not necessarily safe for GC.

fschneider@chromium.org	b93a0f5d9a	Second attempt: Improve our type feedback by recogizining never-executed IC calls for binary operations. This is an improved version of my earlier change r5970. It avoids degrading the non-optimized code. Initially we emit a conditional branch that is either always- or never-taken after a smi-check (depending on whether we test for smi for for non-smi) Since test-eax always sets the carry-flag to 0 we use jump-if-carry and jump-if-not-carry. The first invocation of the stub patches a jc with a jz and jnc with a jnz-instruction so that the code looks exactly as it was without patching. The only difference is the test- or nop-instruction after the IC-call.

ager@chromium.org	4c6f79ecec	Fix crashes during GC caused by partially initialized objects. The inline allocation code used the expected number of properties to calculate the number of inobject properties for an object instead of getting the actual number from the initial map. It is safer to use the inobject property count from the initial map in any case because that is the amount the instances will get. I think this disconnect got introduced when adding shrinking of objects. Unfortuntely I haven't been able to create a simple reproduction for a test case but this fixes the webpage that exhibits the crash. I'll see if I can create a reproduction tomorrow.

kmillikin@chromium.org	ea910460bd	More refactoring of class Compiler's interface. Change more functions used by the Compiler class to have a uniform interface: they get passed as argument an input/output pointer to a CompilationInfo that they mutate if they succeed, and they return a flag telling whether they succeeded. Also, remove some unnecessary timers. Review URL: http://codereview.chromium.org/3561012 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@5583 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2010-10-04 14:30:43 +00:00
kmillikin@chromium.org	bef3ae07db	Begin a more aggressive refactoring of the Compiler interface. The plan is to use the CompilationInfo class to communicate inputs and outputs to compilation pipeline phases, which each return a boolean success/failure flag. The intent is to make it easier to compose small pieces of the pipeline without having to grow a custom function each time, each taking a half dozen arguments. This change modifies the very front end (the parser).
