[llvm-commits] CVS: llvm/lib/Support/APInt.cpp
Changes in directory llvm/lib/Support:
APInt.cpp updated: 1.32 -> 1.33
---
Log message:
1. Make internal functions take const arguments where they should, just
to be safe.
2. Make internal functions that return a carry/borrow return bool instead
of uint64_t because the carry/borrow can only be in range [0,1].
3. Assert that the pointers to KnuthDiv are all different so that the
result and operands can't overlap.
4. Add debug output to KnuthDiv function.
5. Fix a problem with KnuthDiv by separating the b's complement operation
from the subtraction borrow operation. This fixes a wide range of
division problems, but alas, not all of them.
