> this might be a compiler bug, since -frounding-math should be supported whatever the optimization level (-O2 or -O3). You might want to investigate further and report the bug if any.

Hi, what's the target in the context? Or can you show the partial IR after `-frounding-math`? Currently only X86/SystemZ/PowerPC in LLVM has rather complete support for rounding-mode-aware float operations.
