conversions for external array types, which implement the Typed Array spec. The new code paths are for SSE3 and SSE2 capable processors. The code for non-SSE2 processors is unchanged for now. The ARM port appears to already be correct. Moved the generation of the external array load and store intrinsics to the stub cache (on all platforms) so that they are generated at run time and can take advantage of CPU features. This functionality is covered by the array-unit-tests.html test in the WebGL conformance test suite: http://khronos.org/webgl/wiki/Testing/Conformance https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/array-unit-tests.html Manually verified all of the SSE3/SSE2/non-SSE2 code paths by enabling each in turn. Tested in Chromium on 32-bit Mac OS X and 64-bit Linux.

Extra IC state is only two bits and only supported for call IC-s for now. To change its extra state an IC stub jumps to a new miss stub that goes to runtime as usual but then instead of going megamorphic generates a monomorphic stub with the updated state.

is that the mozilla ones were caused by the safe-point table problem and the deoptimization ones are fixed by adding support for mod and div. Let's see if the buildbot agrees.

This change includes support for safepointtables and adding deoptimization info (but not for deoptimizing). Implemented crankshaft functions: CallCode GenerateSafepointTable RegisterEnvironmentForDeoptimization EmitGoto This change allows us to compile very simple functions with crankshaft: An empty function A function returning a constant. A function returning a parameter. There is 6 disabled tests that require us to be able to deoptimize which is currently not supported.

This change introduces the third template parameters for LIR instructions to specify the number of temp-operands. This is one step towards removing the instruction-summaries. I also added hydrogen-accessors in more places and refactored the LIR-branch instructions to have common super-classes to avoid code duplication. Added MUST_USE_RESULT to the functions that record uses and definitions so that all LOperands are stored in the LIR instructions (and not only in the summaries).

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.

When processing register contraints we used to add writable input operands also as temp operands to the same instruction. This does not seem necessary since we create a fresh virtual register for writable inputs and insert a definition in the gap before the instruction.
