Bug ID: 38086
Summary: InstCombiner::visitSelectInst incorrectly checks for
nsz on an fcmp
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations

nsz doesn't affect the result of an fcmp.
Not sure what the right solution is here... should we put fast-math flags on
selects? Check some function-global flag? Check if the result of the select is
used by an nsz operation?
