Enable type feedback for branch statement and function call · eb27eb03

ulan@chromium.org authored Dec 28, 2012

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.

Refactor and improve inlined double-aligned allocations · 17326e87

danno@chromium.org authored Dec 28, 2012

Change is performance neutral but generates smaller code and encapsulates double alignment in the macro-assembler rather than at the allocation site.
