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

[Reid Spencer]

Changes in directory llvm/include/llvm:

DerivedTypes.h updated: 1.79 -> 1.80
---
Log message:

Provide an isPowerOf2ByteWidth method for the IntegerType class. This will
mostly be used by back ends that wish to distinguish between integer types
that fit evenly within a natural integer type and those that don't.
