Unfortunatelly scripts/abilist.awk does not differentiate between default version
and compat version from objdump (line 52 removes the parentesis around it), so it does
not check if all the finite symbol indeed has been converted to compat ones. Maybe it
is something we might enhance in the future, although it would require some additional
metadata to parse what from the exported ABI is compatibility symbols.
So from checking the resulting binary I am seeing the patch does not address i386/x86_64
__exp10l_finite, __expl_finite, __log_finite, __exp_finite, and __logl_finite.
Neither m68k __exp10l_finite, __expl_finite, __log_finite, __coshl_finite,
__asinl_finite, __coshf_finite, __atanhl_finite, __expf_finite,__fmod_finite,
__log2l_finite, __log2f_finite, __sinhf_finite, __sinh_finite, __exp_finite,
__exp2f_finite, __acosf_finite, __exp10f_finite, __log10l_finite, __asin_finite,
__log2_finite, __logf_finite, __acos_finite, __acosl_finite, __remainderf_finite,
__exp10_finite, __fmodl_finite, __exp2_finite, __cosh_finite, __exp2l_finite,
__atanhf_finite, __atanh_finite, __log10_finite, __remainder_finite, __logl_finite,
__log10f_finite, __sinhl_finite, __sqrtl_finite, __fmodf_finite, __asinf_finite,
__sqrt_inline, and __sqrtf_inline.
So I have create a personal branch with reviewing suggestion below along with the
fixes for the aforement mentioned symbols [1]. What do you think.

I think it would be better to move the logic to whether create the finite
to its own headers, as we do for ldbl-opt. Something like:
--
$ cat sysdeps/ieee754/libm-alias-finite.h
#ifndef _LIBM_ALIAS_FINITE_H
#define _LIBM_ALIAS_FINITE_H
#include <first-versions.h>
#include <shlib-compat.h>
/* The -ffinite-math symbols were added on GLIBC 2.15 and moved to compat
symbol so newer architectures do not require to support it. */
#if SHLIB_COMPAT (libm, GLIBC_2_15, GLIBC_2_30)
# define libm_alias_finite(from, to) \
libm_alias_finite1(from, to)
# define libm_alias_finite1(from, to) \
compat_symbol (libm, \
from, \
to ## _finite, \
FIRST_VERSION_libm_ ## to ## _finite);
#else
# define libm_alias_finite(from, to)
#endif
#endif
--
And then on required implementation we do:
--
#include <libm-alias-finite.h>
type
__ieee754_symbol (...)
{
[...]
}
libm_alias_finite (__ieee754_symbol, __symbol)

Same as before we can rather define declare_mgen_finite_alias as:
--
#ifndef declare_mgen_finite_alias_x
#define declare_mgen_finite_alias_x(from, to) \
libm_alias_finite (from, to)

Another advantage of using the libm_alias_finite defined above is there is no
need to define to override the compat_symbol macro (the first-versions.h take
care of it). We just need to add the internal symbol on float128_private.h
so libm_alias_finite second argument can parse the minimal version based on
first-versions.h.

Same as before, you just need to redefine declare_mgen_finite_alias_x to call
libm_alias_finite.
