Hi,
There is a build failure for SH during compiling stdlib/strtold_l.c:
strtold_l.c:61: error: 'strtold_l' aliased to undefined symbol '__strtold_l'
In Aug 6 Roland's change, libc_hidden_proto (__strtold_l) is added
to include/stdlib.h and weak_alias (__STRTOLD, STRTOLD) is added to
stdlib/strtold_l.c. It seems that libc_hedden_def is needed also
for __strtold_l just before the above weak_alias statement. Is it
right? x86 uses sysdeps/ieee754/ldbl-96/strtold_l.c which includes
stdlib/strtod_l.c instead of stdlib/strtold_l.c and the corresponding
libc_hedden_def was added to stdlib/strtod_l.c at that time.
The attached patch works for me, though I suspect that I've missed
something.
Regards,
kaz

I believe you should match what has been added to strtod_l.c, i.e.:
{
return INTERNAL (__STRTOD) (nptr, endptr, 0, loc);
}
+#if defined _LIBC
+libc_hidden_def (__STRTOLD)
+libc_hidden_ver (__STRTOLD, STRTOLD)
+#endif
weak_alias (__STRTOLD, STRTOLD)
otherwise calls to strtold_l from within libc.so will go through
PLT. stdlib/strtold_l.c is only used on
sizeof (double) == sizeof (long double) arches, which I'm afraid
I don't have access to any.

I've tried your patch and got
In file included from wcstold_l.c:32:
../stdlib/strtold_l.c:60: error: 'wcstold_l' undeclared here (not in a function)../stdlib/strtold_l.c:60: warning: type defaults to 'int' in declaration of '__EI_wcstold_l'
../stdlib/strtold_l.c:60: warning: type defaults to 'int' in declaration of '__EI_wcstold_l'
So perhaps, is the patch
{
return INTERNAL (__STRTOD) (nptr, endptr, 0, loc);
}
+#if defined _LIBC && !defined USE_WIDE_CHAR
+libc_hidden_def (__STRTOLD)
+libc_hidden_ver (__STRTOLD, STRTOLD)
+#endif
weak_alias (__STRTOLD, STRTOLD)
ok?

Either stdlib/strtold_l.c, or wcsmbs/wcstold_l.c then needs to
#include <wchar.h>

Ah, I see. With copying
#if defined _LIBC || defined HAVE_WCHAR_H
# include <wchar.h>
#endif
lines from stdlib/strtod_l.c to strtold_l.c, the error went away.
Thanks for your suggenstions! The attached patch is the revised
one. Uli, does it look Ok?
