Subject: Update.
X-Git-Tag: upstream/2.30~19236
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7661d9f7838cedc4e35bf86b83cd4d27e41c8e4d;p=external%2Fglibc.git

Update.

2003-05-26  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/x86_64/pthread_cond_broadcast.S: Fix
	typo in register name.
	* sysdeps/unix/sysv/linux/x86_64/pthread_cond_signal.S: Use parameters
	correctly.  Actually use requeue.  Little optimization.
	* sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S: Store
	mutex address early.  Handle cancellation state as 32-bit value.
	* sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S: Likewise.
	Remove unnecessary label.
