* locale/newlocale.c (__newlocale): If setting all categories to "C",
just return &_nl_C_locobj instead of copying it. * locale/freelocale.c (__freelocale): Check for &_nl_C_locobj. * locale/duplocale.c (__duplocale): Likewise. 2002-10-07 Roland McGrath <roland@frob.com> * config.h.in (HAVE_I386_SET_GDT): New #undef. * sysdeps/mach/configure.in: Define it with new check for i386_set_gdt. * sysdeps/mach/configure: Regenerated. 2002-10-06 Franz Sirl <Franz.Sirl-kernel@lauterbach.com> * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h (INLINE_SYSCALL): Add all necessary register outputs for syscall-clobbered registers. 2002-10-02 David Mosberger <davidm@hpl.hp.com> * sysdeps/ia64/bzero.S: Rewritten by Sverre Jarp to tune for Itanium 2 (and Itanium). Fix unwind directives and make it fit in 80 columns. * sysdeps/ia64/memset.S: Ditto. * sysdeps/ia64/memcpy.S: Ditto. Move jump table to .rodata section. 2002-10-03 Roland McGrath <roland@frob.com> * sysdeps/mach/hurd/i386/init-first.c (_hurd_stack_setup): Add clobbers to asm.
