Juergen Ributzka d24494d672 [FastISel] ... Currently instructions are folded very aggressively for AArch64 into the memory operation, which can lead to the use of killed operands: %vreg1<def> = ADDXri %vreg0<kill>, 2 %vreg2<def> = LDRBBui %vreg0, 2 ... = ... %vreg1 ... This usually happens when the result is also used by another non-memory instruction in the same basic block, or any instruction in another basic block. This fix teaches hasTrivialKill to not only check the LLVM IR that the value has a single use, but also to check if the register that represents that value has already been used. This can happen when the instruction with the use was folded into another instruction (in this particular case a load instruction). This fixes rdar://problem/18142857. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216634 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-28 00:09:46 +00:00
