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

[Alkis Evlogimenos]

Changes in directory llvm/include/llvm/CodeGen:

MachineInstr.h updated: 1.120 -> 1.121

---
Log message:

When an instruction like: A += B had both A and B virtual registers
spilled, A was loaded from its stack location twice. This fixes the bug.
