Jim Grosbach fa85eb6237 Fix PR6696 and PR6663 When a frame pointer is not otherwise required, and dynamic stack alignment is necessary solely due to the spilling of a register with larger alignment requirements than the default stack alignment, the frame pointer can be both used as a general purpose register and a frame pointer. That goes poorly, for obvious reasons. This patch brings back a bit of old logic for identifying the use of such registers and conservatively reserves the frame pointer during register allocation in such cases. For now, implement for X86 only since it's 32-bit linux which is hitting this, and we want a targeted fix for 2.7. As a follow-on, this will be expanded to handle other targets, as theoretically the problem could arise elsewhere as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100559 91177308-0d34-0410-b5e6-96231b3b80d8		2010-04-06 20:26:37 +00:00
