Description

5 years ago
JSOP_NEWOBJECT should use the MacroAssembler's getNewObject() path where possible. In terms of benchmarks, this only affects v8-splay, which hits the LNewObject callVM() path 508,999 times.

Inline allocation for JSOP_NEWOBJECT.

Easy, since all the existing machinery can be reused.
Makes v8-splay ~25% faster locally on x86. (125ms -> 95ms.)
