David Majnemer 8a55c2ecd4 X86: Bad peephole interaction between adc, MOV32r0 ... The peephole tries to reorder MOV32r0 instructions such that they are before the instruction that modifies EFLAGS. The problem is that the peephole does not consider the case where the instruction that modifies EFLAGS also depends on the previous state of EFLAGS. Instead, walk backwards until we find an instruction that has a def for EFLAGS but does not have a use. If we find such an instruction, insert the MOV32r0 before it. If it cannot find such an instruction, skip the optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182184 91177308-0d34-0410-b5e6-96231b3b80d8		2013-05-18 01:02:03 +00:00
