Fortran never uses the _finite names because it never uses the C header
that can declare the functions to use those asm names.

Well, finite-only entry points avoid wrappers for the scalar functions -
it's just that suitable optimized implementations could avoi

There are static-only wrappers in libmvec_nonshared.a to work around the
GCC limitation (not included in the shared library, so less efficient th

This is a proposed GCC patch that allows targets to modify the names of
the libmvec routines that get called. Currently, if you build ToT GCC
on Aarch64 and include this glibc patch:
https://sourceware.org/ml/libc-alpha/2019-03/msg00106.html
And then compile a call to expf which gets vec
