Subject: Forced inlining of some GC-related methods.
X-Git-Tag: upstream/4.7.83~15045
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=54b4b1ecc2b023e6104a867d04d34effa424734d;p=platform%2Fupstream%2Fv8.git

Forced inlining of some GC-related methods.

The selection of methods were driven by GCC's -Winline plus some benchmarking.
On ia32, the additional amount of code is roughly 63kB (= 0.07% of Chrome ;-).

BUG=v8:1607
