2001-07-06  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/i386/sigaction.c (RESTORE2): Put asm
	explicitly into .text section.

2001-04-16  Jes Sorensen  <jes@linuxcare.com>

	* sysdeps/unix/sysv/linux/ia64/bits/sigcontext.h (struct sigcontext):
	Add 16 longwords reserved for future use to match changes in the
	kernel.

2001-07-03  Jes Sorensen  <jes@trained-monkey.org>

	* sysdeps/ia64/strncpy.S: Call strnlen() when determining the
	string length rather than strlen(). Solves the performance problem
	of doing strlen on a 5MB string when strncpy was called with a
	length argument of 5 bytes.

2001-07-02  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/sparc/sparc32/dl-machine.h (elf_machine_rela): Handle
	R_SPARC_UA16 and R_SPARC_UA32.
	* sysdeps/sparc/sparc64/dl-machine.h (elf_machine_rela): Likewise.

2001-07-01  Stephen L Moshier  <moshier@mediaone.net>

	* sysdeps/ieee754/ldbl-96/e_acoshl.c (__ieee754_acoshl):
	acosh(x) = ln(2x) if x > 2^30.
	* sysdeps/ieee754/ldbl-128/e_acoshl.c (__ieee754_acoshl):
	acosh(x) = ln(2x) if x > 2^54.

	* sysdeps/hppa/dl-machine.h (elf_machine_rela): Handle relocs
