[llvm-commits] CVS: llvm/lib/AsmParser/llvmAsmParser.y

[Chris Lattner]

Changes in directory llvm/lib/AsmParser:

llvmAsmParser.y updated: 1.91 -> 1.92

---
Log message:

Recently changed getelementptr to use 'long' indexes for sequential types 
instead of uints.  This adds a translation scheme to be backwards compatible 
with old .ll files.
