Hi,

I just noticed that the upstream LLVM is no longer capable of compiling musl 1.2.0 (and possibly more recent versions too) when -frounding-math is in use. I bisected the LLVM commit to https://reviews.llvm.org/D87822, and pointed the problem there.

Just reporting in case someone else also has issues with this.

Best,
Joao.
