[llvm-commits] CVS: llvm/include/llvm/Constants.h

[Reid Spencer]

Changes in directory llvm/include/llvm:

Constants.h updated: 1.135 -> 1.136
---
Log message:

Add an isUnitValue method for comparison against 1. This just follows a
common pattern with isNullValue, isAllOnesValue, etc. It also helps to
prevent things like getZExtValue() == 1, which could assert for large 
bitwidths.
