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

[Alkis Evlogimenos]

Changes in directory llvm/include/llvm/CodeGen:

MachineBasicBlock.h updated: 1.21 -> 1.22

---
Log message:

Refactor rewinding code for finding the first terminator of a basic
block into MachineBasicBlock::getFirstTerminator().

This also fixes a bug in the implementation of the above in both
RegAllocLocal and InstrSched, where instructions where added after the
terminator if the basic block's only instruction was a terminator (it
shouldn't matter for RegAllocLocal since this case never occurs in
practice).
