clang-p2996/llvm/test/Transforms/Attributor/denormal-fp-math.ll
Matt Arsenault 850ec7bbb1 Attributor: Try to propagate concrete denormal-fp-math{-f32} 
Allow specialization of functions with "dynamic" denormal modes to a
known IEEE or DAZ mode based on callers. This should make it possible
to implement a is-denormal-flushing-enabled test using
llvm.canonicalize and have it be free after LTO.
