Support strtof128 etc. aliases.
This patch adds support for building strtof128, wcstof128, strtof128_l
and wcstof128_l as aliases, in the case of __HAVE_FLOAT128 &&
!__HAVE_DISTINCT_FLOAT128.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by this patch. Also tested together with
changes to enable float128 aliases.
* stdlib/strtold.c: Include <bits/floatn.h>
[__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (strtof128): Define
and later undefine as macro. Define as weak alias if
[!USE_WIDE_CHAR].
[__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (wcstof128): Define
and later undefine as macro. Define as weak alias if
[USE_WIDE_CHAR].
* sysdeps/ieee754/ldbl-128/strtold_l.c [__HAVE_FLOAT128 &&
!__HAVE_DISTINCT_FLOAT128] (strtof128_l): Define and later
undefine as macro. Define as weak alias if [!USE_WIDE_CHAR].
[__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (wcstof128_l):
Define and later undefine as macro. Define as weak alias if
[USE_WIDE_CHAR].
* sysdeps/ieee754/ldbl-64-128/strtold_l.c: Include
<bits/floatn.h>.
[__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (strtof128_l):
Define and later undefine as macro. Define as weak alias if
[!USE_WIDE_CHAR].
[__HAVE_FLOAT128 && !__HAVE_DISTINCT_FLOAT128] (wcstof128_l):
Define and later undefine as macro. Define as weak alias if
[USE_WIDE_CHAR].
