Bug ID: 37761
Summary: [SelectionDAG] Generalise
SelectionDAG::computeOverflowKind to support other
opcodes
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Common Code Generator Code
Assignee: unassignedb...@nondot.org
Reporter: llvm-...@redking.me.uk
CC: deadal...@gmail.com, lebedev...@gmail.com,
llvm-bugs@lists.llvm.org, spatel+l...@rotateright.com
SelectionDAG::computeOverflowKind is currently only to be used for additions;
it'd be useful for it to also handle signed/unsigned ISD::SUB and ISD::MUL (to
cover all the SADDO/UADD, SSUBO/USUBO and SMULO/UMULO nodes).
