Spotted while crosscompiling musl from x86_64 to aarch64 - looks like something
that will happen on a native aarch64 compiler as well.
-frounding-math is needed.
Test case can be reduced to a one-liner.
$ echo 'float a() { return 0; }' >test.c
$ clang -target aarch64-openmandriva-linux-gnu -frounding-math -o test.o -c
test.c
clang:
