[llvm-commits] CVS: llvm/include/llvm/Transforms/Utils/Local.h

[Chris Lattner]

Changes in directory llvm/include/llvm/Transforms/Utils:

Local.h updated: 1.24 -> 1.25
---
Log message:

Change constant folding APIs to take an optional TargetData, and change
ConstantFoldInstOperands/ConstantFoldCall to take a pointer to an array
of operands + size, instead of an std::vector.

Diffs of the changes:  (+6 -3)
