Evan Cheng	794aaa79e2	Disable codegen prepare critical edge splitting. Machine instruction passes now break critical edges on demand. llvm-svn: 114633	2010-09-23 06:55:34 +00:00
Evan Cheng	d703df67ce	Do not force indirect tailcall through fixed registers: eax, r11. Add support to allow loads to be folded to tail call instructions. llvm-svn: 98465	2010-03-14 03:48:46 +00:00
Bill Wendling	00810c39da	revert r98270. llvm-svn: 98281	2010-03-11 19:50:31 +00:00
Evan Cheng	31fe835bf2	Bad bad bug. x86 force indirect tail call address into eax when it's meant to force it into a call preserved register instead. Change it to ecx for now. llvm-svn: 98270	2010-03-11 18:49:14 +00:00
Evan Cheng	40905b4302	Allow all types of callee's to be tail called. But avoid automatic tailcall if the callee is a result of bitcast to avoid losing necessary zext / sext etc. llvm-svn: 95195	2010-02-03 03:28:02 +00:00
Dan Gohman	40503396da	Eliminate more uses of llvm-as and llvm-dis. llvm-svn: 81290	2009-09-08 23:54:48 +00:00
Arnold Schwaighofer	796a271c5f	Change the calling convention used when tail call optimization is enabled from CC_X86_32_TailCall to CC_X86_32_FastCC. llvm-svn: 56436	2008-09-22 14:50:07 +00:00
Arnold Schwaighofer	33ad850d93	Add indirect tail call (function pointer) examples. llvm-svn: 56127	2008-09-11 22:24:28 +00:00
