Please take a look.
This is the first CL in a series towards having count-based profiling. It
adds a
"self-optimization" header to primitive functions, and propagates a few
bits of
information about compilation and IC patching events to the runtime
profiler.
The most interesting changes are:
full-codegen-{arm,ia32,x64}.cc: generating the self-optimization header
runtime-profiler.{h,cc}: new behavior if FLAG_counting_profiler; old code
moved
to "else {...}" sections.
ic-inl.h: Mark functions on the stack as not-yet-stable (in the type
information
sense) when an IC is patched.
Description:
Count-based profiling for primitive functions (hidden behind a flag)
