Changes in directory llvm/lib/CodeGen/SelectionDAG:
SelectionDAGISel.cpp updated: 1.289.2.1 -> 1.289.2.2
---
Log message:
Make some simplifications for ConstantInt:
1. Get rid of getRawValue, replace with getZExtValue
2. Single constructor (uint64_t) and get method (int64_t)
3. Canonicalize the constant to a zero extended unsigned 64-bit integer when
it is created.
4. Adjust getZExtValue() to be a do-nothing (just returns the already
canonicalized value).
5. Compensate for above changes everywhere else.
