This helps SunSpider by 0.2% on MIPS. Thanks! Regards, Chao-ying 255052 1 62358 fu 2010-07-22 16:24:49 -0700 Created attachment 62358 Use div for MIPS op_mod The patch replaces X86Registers::eax/ecx/edx with regT0/regT2/regT1, so that MIPS can reuse source code to implement op_mod. The MIPS build was ok, while I didn't test x86 build. Thanks! 255521 2 kent.hansen 2010-07-23 12:55:19 -0700 (In reply to comment #1) > Created an attachment (id=62358) [details] > Use div for MIPS op_mod > > The patch replaces X86Registers::eax/ecx/edx with regT0/regT2/regT1, so that MIPS can reuse source code to implement op_mod. The MIPS build was ok, while I didn't test x86 build. Thanks! For X86 I'd ASSERT(regT0 == eax), etc., since the registers are implicit in the div instruction. It's important that this information is preserved, e.g. in case someone decides to change regT0 to r13 on x64. :) 255551 3 fu 2010-07-23 14:20:35 -0700 (In reply to comment #2) > (In reply to comment #1) > > Created an attachment (id=62358) [details] [details] > > Use div for MIPS op_mod > > > > The patch replaces X86Registers::eax/ecx/edx with regT0/regT2/regT1, so that MIPS can reuse source code to implement op_mod.

It's important that this information is preserved, e.g. in case someone decides to change regT0 to r13 on x64. :) Yes. You are right. I will update the patch to have ASSERT() for X86 and X86_64.

Although the whole code should be moved to their respective MacroAssembler header files, and refactor this code to be platform independent (This happened with other math functions as well, like the floating point division). 270213 6 62470 oliver 2010-08-26 16:53:05 -0700 Comment on attachment 62470 Assert x86 registers r=me 270411 7 62470 commit-queue 2010-08-27 04:12:28 -0700 Comment on attachment 62470 Assert x86 registers Rejecting patch 62470 from commit-queue.
