[llvm-dev] [Unsafe-fp-math] Merge attribute for inlining

Hello dev,

I have a question about unsafe-fp-math function attribute. Currently LLVM merges this attribute for inlining with logical AND. That means if caller has this attribute set but callee has not, LLVM will reset this attribute on caller. But shouldn't we respect this attribute on caller? If caller wants to perform unsafe fp operation, any code that gets inlined should be allowed to do unsafe fp operation, right? Thanks!
