From 2ff16e041a767bfedec01b6f614ecffb3fb0f653 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 20 Mar 2003 11:40:51 +0000 Subject: * sysdeps/powerpc/bits/atomic.h (atomic_exchange): Remove unused variable. Remove superfluous memory clobber. * include/atomic.h: Syntax braino fix. * posix/tst-nice.c (do_test): Use %m formats instead of printing errno in decimal. Don't bail if niced at start. Just check that nice call bumps the total at all. --- sysdeps/powerpc/bits/atomic.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'sysdeps/powerpc/bits') diff --git a/sysdeps/powerpc/bits/atomic.h b/sysdeps/powerpc/bits/atomic.h index 13001cb3c0..956272c482 100644 --- a/sysdeps/powerpc/bits/atomic.h +++ b/sysdeps/powerpc/bits/atomic.h @@ -111,14 +111,14 @@ typedef uintmax_t uatomic_max_t; #define atomic_exchange(mem, value) \ ({ if (sizeof (*mem) != 4) \ abort (); \ - int __val, __tmp; \ + int __val; \ __asm __volatile (__ARCH_REL_INSTR "\n" \ "1: lwarx %0,0,%2\n" \ " stwcx. %3,0,%2\n" \ " bne- 1b" \ : "=&r" (__val), "=m" (*mem) \ : "r" (mem), "r" (value), "1" (*mem) \ - : "cr0", "memory"); \ + : "cr0"); \ __val; }) -- cgit v1.2.3
