[llvm-commits] CVS: llvm/lib/Target/IA64/IA64ISelDAGToDAG.cpp

[Duraid Madina]

Changes in directory llvm/lib/Target/IA64:

IA64ISelDAGToDAG.cpp updated: 1.7 -> 1.8
---
Log message:

oops, forgot to load GP for indirect calls, though the old code now commented
out failed (e.g. methcall) - now the code compiles, though it's not quite
right just yet (tm) ;)

would fix this but it's 3am! :O
