Quoting Christian Bruel <christian.br...@st.com>:
Edited to apply on top of latest Joern's patch. Certainly not optimal but it fixes the QNaNs checks for builtins and inlined unordered comparisons for -mieee or -fno-inite-math-only.
You are still on the wrong track; as I said in my earlier message, we should not emit the library call for SH4 in the first place. Please try the attached patch instead.
