--- Comment #3 from Dave Love <fx at gnu dot org> ---
Apologies; this isn't the compiler.  It seems the glibc that Advanced Toolkit
gcc 8 uses is responsible for the difference between that and 10.  I tried to
test that with LD_LIBRARY_PATH, but find you have to build with AT's ld64.so.2
to see the effect.

It looks as though sincos in ppc64le glibc-2.17 is just sin+cos, though I can't
immediately find my way in the source to check.  I'd assumed it was optimized.
