      Notify CPU profiler when calling native getters · c4224f09
      yurys@chromium.org authored 
      This change modifies code produced by BaseLoadStubCompiler::GenerateLoadCallback so that instead of calling AccessorGetter direcly it calls InvokeAccessorGetter which changes VM state and calls the actual callback. This way CPU profiler knows which external callback is being executed in this case. Indirect call happens only if CpuProfiler::is_profiling() is true.

This is exactly same change as r15116 with a build fix for test-api.cc

Broke compilation on the bots with an error that doesn't occur locally:

      Make the arm port build cleanly with Clang. · 23ee3f28
      ulan@chromium.org authored 
      This fixes the following two warnings, so that "make all" builds cleanly
with Clang:

  src/arm/macro-assembler-arm.h:1410:7: error: private field
  'instructions_' is not used
        [-Werror,-Wunused-private-field]
          int instructions_;  // Number of instructions of the expected patch size.

        condition is false [-Werror,-Wsometimes-uninitialized]

  ../src/arm/simulator-arm.cc:407:21: note: uninitialized use occurs here
          end = cur + words;
                      ^~~~~
  ../src/arm/simulator-arm.cc:402:16: note: remove the 'if' if its condition is always true
          } else if (argc == next_arg + 1) {

      Allow uint32 value on optimized frames if they are consumed by safe operations. · f476d4d4
      vegorov@chromium.org authored 
      Safe operations are those that either do not observe unsignedness or have special support for uint32 values:

- all binary bitwise operations: they perform ToInt32 on inputs;
- >> and << shifts: they perform ToInt32 on left hand side and ToUint32 on right hand side;
- >>> shift: it performs ToUint32 on both inputs;
- stores to integer external arrays (not pixel, float or double ones): these stores are "bitwise";
- HChange: special support added for conversions of uint32 values to double and tagged values;
- HSimulate: special support added for deoptimization with uint32 values in registers and stack slots;
- HPhi: phis that have only safe uses and only uint32 operands are uint32 themselves.
