Roman Divacky 9d760ae5c6 This patch corrects logic in PPCFrameLowering for save and restore of ... nonvolatile condition register fields across calls under the SVR4 ABIs. * With the 64-bit ABI, the save location is at a fixed offset of 8 from the stack pointer. The frame pointer cannot be used to access this portion of the stack frame since the distance from the frame pointer may change with alloca calls. * With the 32-bit ABI, the save location is just below the general register save area, and is accessed via the frame pointer like the rest of the save areas. This is an optional slot, so it must only be created if any of CR2, CR3, and CR4 were modified. * For both ABIs, save/restore logic is generated only if one of the nonvolatile CR fields were modified. I also took this opportunity to clean up an extra FIXME in PPCFrameLowering.h. Save area offsets for 32-bit GPRs are meaningless for the 64-bit ABI, so I removed them for correctness and efficiency. Fixes PR13708 and partially also PR13623. It lets us enable exception handling on PPC64. Patch by William J. Schmidt! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163713 91177308-0d34-0410-b5e6-96231b3b80d8		2012-09-12 14:47:47 +00:00
