Update.
2001-03-23  Jes Sorensen  <jes@linuxcare.com>

	* sysdeps/unix/sysv/linux/ia64/sysdep.h (ENTRY): Moved to ...
	* sysdeps/ia64/sysdep.h: ...here.

	* sysdeps/ia64/sysdep.h (LOCAL_ENTRY): Define.
	* sysdeps/ia64/sysdep.h (LOCAL_LEAF): Define.

	* sysdeps/ia64/_mcount.S (_mcount_ret_helper): Use LOCAL_LEAF() to
	declare instead of LEAF().  Suggestion from David Mosberger.

2001-03-21  David Mosberger  <davidm@hpl.hp.com>

	* sysdeps/unix/sysv/linux/ia64/sysdep.h (CALL_MCOUNT): Add unwind
	directives.
	(PSEUDO): Drop .psr and .lsb directives.

	* sysdeps/unix/sysv/linux/ia64/setjmp.S: Ditto.  Add unwind
	directives.
	* sysdeps/unix/sysv/linux/ia64/sysdep.S: Ditto.

	* sysdeps/ia64/elf/start.S: Misc cleanup: remove .psr and .lsb
	directives etc.
	* sysdeps/unix/sysv/linux/ia64/brk.S: Ditto.
	* sysdeps/unix/sysv/linux/ia64/__longjmp.S: Ditto.
	* sysdeps/ia64/_mcount.S: Remove .psr and .lsb directives (no
	longer needed).  Add unwind directives.

	* sysdeps/ia64/sysdep.h: Define ASM_UNW_PRLG_RP, ASM_UNW_PRLG_PFS,
	ASM_UNW_PRLG_PSP, ASM_UNW_PRLG_PR, and ASM_UNW_PRLG_GRSAVE.

2001-03-21  Paul Eggert  <eggert@twinsun.com>

	* posix/regex.h (RE_INVALID_INTERVAL_ORD): New macro.
	(RE_SYNTAX_POSIX_EGREP): Use it.
	* posix/regex.c (regex_compile): Implement it.

2001-03-21  Paul Eggert  <eggert@twinsun.com>

	* posix/regex.c (GET_UNSIGNED_NUMBER): Check for overflow.
	Rewrite to avoid duplicate code.

2001-03-21  H.J. Lu  <hjl@gnu.org>

	* elf/Makefile (tests): Don't depend on $(objpfx)tst-pathopt.out
	for cross-compiling.
	($(objpfx)tst-pathopt.out): Undo the last change.
