Hi guys, here's a start on the entry hook API along with a test for it. Note
that as-is this will test only the non-optimized codegen, I'd appreciate
some
tips on how to also cover the optimized path.
I made the entry hook function an uintptr_t to emphasize that this you can't
really pass in any old void (*)() - an entry hook really needs to be
implemented
in asm. If there's a better or more appropriate way to express this in
V8isms,
please let me know.
Description:
Implements a new API to set a function entry hook for profiling.
Exposes a new API; V8::SetFunctionEntryHook.
If a non-NULL function entry hook is set, the code generator(s) will invoke
on
the entry hook at the very start of each generated function.
