Some x86-32 calls pop values off the stack, and we need to readjust the stack pointer after the call. This happens when ADJCALLSTACKUP is eliminated. It could happen that spill code was inserted between the CALL and ADJCALLSTACKUP instructions, and we would compute wrong stack pointer offsets for those frame index references. Fix this by inserting the stack pointer adjustment immediately after the call instead of where the ADJCALLSTACKUP instruction was erased. I don't have a test case since we don't currently insert code in that position. We will soon, though. I am testing a regalloc patch that didn't work on Linux because of this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134113 91177308-0d34-0410-b5e6-96231b3b80d8
