Update.
2001-09-29 Jes Sorensen <jes@trained-monkey.org>
* sysdeps/unix/sysv/linux/ia64/bits/sigcontext.h (struct sigcontext):
Add sc_loadrs and sc_rbs_bas to match current kernel.
2001-09-27 Jakub Jelinek <jakub@redhat.com>
* sysdeps/sparc/sparc64/fpu/libm-test-ulps: Update.
* sysdeps/ieee754/ldbl-128/s_erfl.c (__erfcl): Fix erfc(-inf).
2001-09-27 Jakub Jelinek <jakub@redhat.com>
* elf/dl-open.c (dl_open_worker): If l_opencount of freshly loaded
object has been bumped because of relocation dependency, avoid
duplicates in l_scope.
(show_scope): Fix typos.
* elf/Makefile: Add rules to build and run reldep6.
* elf/reldep6.c: New file.
* elf/reldep6mod0.c: New file.
* elf/reldep6mod1.c: New file.
* elf/reldep6mod2.c: New file.
* elf/reldep6mod3.c: New file.
* elf/reldep6mod4.c: New file.
2001-09-26 Jakub Jelinek <jakub@redhat.com>
* sysdeps/sparc/sparc64/dl-machine.h (elf_machine_fixup_plt): Call
sparc64_fixup_plt.
(sparc64_fixup_plt): Moved from elf_machine_fixup_plt. Optimize
near jumps and 0xfffff800XXXXXXXX target addresses, no thread safety
for non-lazy binding. Fix .plt[32768+] handling.
(elf_machine_plt_value): Don't add addend.
(elf_machine_rela): Call sparc64_fixup_plt instead of
elf_machine_fixup_plt.
(elf_machine_runtime_setup, TRAMPOLINE_TEMPLATE): Optimize for
dynamic linker at 0xfffff800XXXXXXXX.
* sysdeps/sparc/sparc32/fpu/libm-test-ulps: Update.
