[llvm-commits] CVS: llvm/lib/Target/PowerPC/PowerPCInstrInfo.td

[Chris Lattner]

Changes in directory llvm/lib/Target/PowerPC:

PowerPCInstrInfo.td updated: 1.49 -> 1.50
---
Log message:

Fix a problem where the PPC backend lost track of the fact that it had
to save and restore the LR register on entry and exit of a leaf function
that needed to access globals or the constant pool.  This should hopefully
fix oscar from sending the PPC tester spinning out of control.
