[llvm-commits] CVS: llvm/lib/CodeGen/AsmPrinter.cpp

[Chris Lattner]

Changes in directory llvm/lib/CodeGen:

AsmPrinter.cpp updated: 1.107 -> 1.108
---
Log message:

If a target uses a GOT, put it in the jt data section, not the text 
section.  This will fix alpha when Andrew implements 
AlphaTargetMachine::getTargetLowering().
