Bug ID: 40376
Summary: TargetTransformInfo::getCmpSelInstrCost should
discriminate between comparison codes
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Common Code Generator Code
Assignee: unassignedb...@nondot.org

Some ISAs (e.g. SSE) have limited integer/float comparison modes, we need to
account for this in TTI::getCmpSelInstrCost calls so we can more accurately
model costs.
