================
Comment at: llvm/test/CodeGen/X86/sqrt-fastmath-mir.ll:115
 
-attributes #0 = { "unsafe-fp-math"="true" "reciprocal-estimates"="sqrt:2" }
-attributes #1 = { nounwind readnone }
+attributes #0 = { "unsafe-fp-math"="true" "reciprocal-estimates"="sqrt:2" "denormal-fp-math"="ieee,ieee" }
+attributes #1 = { "unsafe-fp-math"="true" "reciprocal-estimates"="sqrt:2" "denormal-fp-math"="ieee,preserve-sign" }
----------------
Double-check my understanding: we have the "ieee,ieee" attribute here, but we would never expect to see that in practice?
