[llvm-commits] CVS: llvm/include/llvm/CodeGen/MachineInstr.h

[Chris Lattner]

Changes in directory llvm/include/llvm/CodeGen:

MachineInstr.h updated: 1.199 -> 1.200
---
Log message:

setOperand should not zap the operand list or add implicit operands to an 
instruction.  Doing so breaks the FP stackifier, the alpha branch selector
the sparc fpmover.

This fixes PR1012: http://llvm.org/PR1012  and CodeGen/X86/fp-stack-compare.ll
