Update.

2000-07-31  Jes Sorensen  <jes@linuxcare.com>

	* sysdeps/ia64/elf/initfini.c: Kill dummy section since align and
	endp statements have already been added.

2000-04-18  David Mosberger  <davidm@hpl.hp.com>

	* sysdeps/unix/sysv/linux/ia64/sysdep.h: Include
	<sysdeps/ia64/sysdep.h>.

	* sysdeps/ia64/_mcount.S: New file.

	* sysdeps/ia64/elf/initfini.c (_init): Preserve gp around call to
	__gmon_start__.  Fix up extraneous whitespace.

2000-01-12  H.J. Lu  <hjl@gnu.org>

	* sysdeps/ia64/elf/initfini.c: New file.

2000-07-31  Jes Sorensen  <jes@linuxcare.com>

	* sysdeps/unix/sysv/linux/ia64/clone.S: Add stop bit to avoid WAW
	dependency between branch and ar.pfs write.
