[llvm-commits] CVS: llvm/lib/Target/SparcV8/SparcV8ISelDAGToDAG.cpp

[Chris Lattner]

Changes in directory llvm/lib/Target/SparcV8:

SparcV8ISelDAGToDAG.cpp updated: 1.54 -> 1.55
---
Log message:

Silly Sparc is big endian.  If we have to load args out of incoming stack slots
that are smaller than an int, make sure to adjust the frame pointer to take
this into consideration.
