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.
