[llvm-commits] CVS: llvm/lib/Target/PowerPC/PPC32ISelPattern.cpp

[Nate Begeman]

Changes in directory llvm/lib/Target/PowerPC:

PPC32ISelPattern.cpp updated: 1.8 -> 1.9
---
Log message:

Fix that pesky floats in integer regs problem by assigning the f32 type to
the correct register class.  Also remove the loading of float data into int
regs part of varargs; it will need to be implemented differently later.


---
Diffs of the changes:  (+4 -8)
