MIPS: Enable type feedback for branch statement and function call · 74026ea4

ulan@chromium.org authored Jan 07, 2013

Port r13288 (5fa2c889)

Original commit message:
This change associates TypeFeedbackIds with ToBoolean stubs in
full-compiled code on ARM, allowing their information to be used in
Crankshaft. This eliminates unnecessary checks, especially in
DoBranch.

Replaced a bailout ID assertion with quadratic time complexity by a linear one. · 8a2cca52

svenpanne@chromium.org authored Jan 04, 2013

This reduces the time to run our test suite in debug mode considerably (from
8:43 to 4:05 on my local workstation using 32 threads). Note that the assertion
is so fast now that it doesn't need to be hidden behind --enable-slow-asserts.
Furthermore, the bookkeeping of the set is not measurable in all our benchmarks,
so I intentionally avoided any #ifdef chaos to keep things simple.

Cleanup RelocInfo::NONE usage. · bb964397

ulan@chromium.org authored Jan 03, 2013

There are now NONE and NONE64 RelocInfo types, but only ARM uses them
both at the same time. They were added in:
  https://chromiumcodereview.appspot.com/11191029/

I'll rename NONE to NONE32 in a later CL.

This CL cleans up the RelocInfo::NONE usage by:
 - Using RelocInfo::IsNone when testing for NONE-ness.
 - Using NONE on 32-bit platforms (MIPS and IA32), and NONE64 on 64-bit
   platforms (x64).

This cleans up the code and prevents it from evolving bugs in the future
because NONE32 and NONE64 are used in misleading ways.
