Dale Johannesen 4150d83abe Make the implicit inputs and outputs of target-independent ... ADDC/ADDE use MVT::i1 (later, whatever it gets legalized to) instead of MVT::Flag. Remove CARRY_FALSE in favor of 0; adjust all target-independent code to use this format. Most targets will still produce a Flag-setting target-dependent version when selection is done. X86 is converted to use i32 instead, which means TableGen needs to produce different code in xxxGenDAGISel.inc. This keys off the new supportsHasI1 bit in xxxInstrInfo, currently set only for X86; in principle this is temporary and should go away when all other targets have been converted. All relevant X86 instruction patterns are modified to represent setting and using EFLAGS explicitly. The same can be done on other targets. The immediate behavior change is that an ADC/ADD pair are no longer tightly coupled in the X86 scheduler; they can be separated by instructions that don't clobber the flags (MOV). I will soon add some peephole optimizations based on using other instructions that set the flags to feed into ADC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72707 91177308-0d34-0410-b5e6-96231b3b80d8		2009-06-01 23:27:20 +00:00
