danno@chromium.org b49dd13c90 MIPS: Branch delay slot and other optimizations. ... List of changes: -added a minor optimization to the Simulator that quickly skips nops in the delay slot -slightly re-worked CEntryStub to save a few instructions CEntryStub now expects the following values: -s0: number of arguments including receiver -s1: size of arguments excluding receiver -s2: pointer to builtin function Two new MacroAssembler functions were added to make usage more convenient: -PrepareCEntryArgs(int num_args) to set up s0 and s1 -PrepareCEntryFunction(const ExternalReference&) to set up s2 -removed branch delay slot nops from the most frequently used code areas -reorganized some code to execute fewer instructions -utilized the delay slot of most Ret instructions This does not cover all Rets, only the most obvious cases. Also added a special version of DropAndRet that utilizes the delay slot. -added some comments to code areas where explanation of the register/delay slot usage may be needed -added an optimization to Jump so it doesn't always pre-load the target register BUG= TEST= Review URL: https://chromiumcodereview.appspot.com/9699071 Patch from Daniel Kalmar <kalmard@homejinni.com>. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@11099 ce2b1a6d-e550-0410-aec6-3dcde31c8c00		2012-03-21 08:41:16 +00:00
