David Greene b87bc95db0 Add hasLoadFromStackSlot and hasStoreToStackSlot to return whether a ... machine instruction loads or stores from/to a stack slot. Unlike isLoadFromStackSlot and isStoreFromStackSlot, the instruction may be something other than a pure load/store (e.g. it may be an arithmetic operation with a memory operand). This helps AsmPrinter determine when to print a spill/reload comment. This is only a hint since we may not be able to figure this out in all cases. As such, it should not be relied upon for correctness. Implement for X86. Return false by default for other architectures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87026 91177308-0d34-0410-b5e6-96231b3b80d8		2009-11-12 20:55:29 +00:00
