SelectionDAG::computeKnownBits
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org
Reporter: llvm-...@redking.me.uk
CC: llvm-bugs@lists.llvm.org, matthew.arsena...@amd.com,
spatel+l...@rotateright.com
Classification: Unclassified
SelectionDAG.computeKnownBits is only testing for common known zero/one bits in
the integer min/max opcodes. This can be a lot better.
