From: Ulrich Drepper <drepper@redhat.com>
Date: Mon, 1 Oct 2001 00:14:14 +0000
Subject: 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.
