ko1 0db407836b * include/ruby/ruby.h: use rb_gc_writebrrier() simply. ... For incremental GC, we need to get a pointer to the objspace. We can share this pointer for the following WB process. And considering icache hit ratio, prcess in the GC. * gc.c (rb_gc_writebarrier): added. * gc.c (gc_writebarrier_generational, gc_writebarrier_incremental): make them NOINLINE because inlining them into rb_gc_writebarrier() makes a prologue code of rb_gc_writebarrier() longer (storing callee save registers). This patch improve the performance of WB on micro-benchmarks. name ruby 2.1 trunk modified vm1_gc_wb_ary* 0.511 0.632 0.532 vm1_gc_wb_ary_promoted* 0.578 0.701 0.674 vm1_gc_wb_obj* 0.419 0.575 0.492 vm1_gc_wb_obj_promoted* 0.537 0.664 0.618 (sec) git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@49987 b2dd03c8-39d4-4d8f-98ff-823fe69b080e		2015-03-17 10:26:39 +00:00
