You mean sysdeps/x86_64/fpu/svml_finite_alias.S and test-libmvec-alias-mod.c?

So concretely, does this mean the strong aliases need to have a #if around it
like:
#if SHLIB_COMPAT (libm, GLIBC_2_15, GLIBC_2_30)
strong_alias (__ieee754_cosh, __cosh_finite)
#endif
Do the abi lists need to be changed too?
