From c648cefb27984db60474ec1747cbfde83c2856d0 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 20 May 2015 00:17:35 -0400 Subject: [PATCH] fix inconsistency in a_and and a_or argument types on x86[_64] conceptually, and on other archs, these functions take a pointer to int, but in the i386, x86_64, and x32 versions of atomic.h, they took a pointer to void instead. --- arch/i386/atomic.h | 8 ++++---- arch/x32/atomic.h | 8 ++++---- arch/x86_64/atomic.h | 8 ++++---- 3 files changed, 12 insertions(+), 12 deletions(-) diff --git a/arch/i386/atomic.h b/arch/i386/atomic.h index 4fe7bded..95fecbdc 100644 --- a/arch/i386/atomic.h +++ b/arch/i386/atomic.h @@ -50,16 +50,16 @@ static inline int a_cas(volatile int *p, int t, int s) return t; } -static inline void a_or(volatile void *p, int v) +static inline void a_or(volatile int *p, int v) { __asm__( "lock ; orl %1, %0" - : "=m"(*(int *)p) : "r"(v) : "memory" ); + : "=m"(*p) : "r"(v) : "memory" ); } -static inline void a_and(volatile void *p, int v) +static inline void a_and(volatile int *p, int v) { __asm__( "lock ; andl %1, %0" - : "=m"(*(int *)p) : "r"(v) : "memory" ); + : "=m"(*p) : "r"(v) : "memory" ); } static inline int a_swap(volatile int *x, int v) diff --git a/arch/x32/atomic.h b/arch/x32/atomic.h index 333098c3..b2014cc0 100644 --- a/arch/x32/atomic.h +++ b/arch/x32/atomic.h @@ -47,16 +47,16 @@ static inline int a_cas(volatile int *p, int t, int s) return t; } -static inline void a_or(volatile void *p, int v) +static inline void a_or(volatile int *p, int v) { __asm__( "lock ; or %1, %0" - : "=m"(*(int *)p) : "r"(v) : "memory" ); + : "=m"(*p) : "r"(v) : "memory" ); } -static inline void a_and(volatile void *p, int v) +static inline void a_and(volatile int *p, int v) { __asm__( "lock ; and %1, %0" - : "=m"(*(int *)p) : "r"(v) : "memory" ); + : "=m"(*p) : "r"(v) : "memory" ); } static inline int a_swap(volatile int *x, int v) diff --git a/arch/x86_64/atomic.h b/arch/x86_64/atomic.h index 333098c3..b2014cc0 100644 --- a/arch/x86_64/atomic.h +++ b/arch/x86_64/atomic.h @@ -47,16 +47,16 @@ static inline int a_cas(volatile int *p, int t, int s) return t; } -static inline void a_or(volatile void *p, int v) +static inline void a_or(volatile int *p, int v) { __asm__( "lock ; or %1, %0" - : "=m"(*(int *)p) : "r"(v) : "memory" ); + : "=m"(*p) : "r"(v) : "memory" ); } -static inline void a_and(volatile void *p, int v) +static inline void a_and(volatile int *p, int v) { __asm__( "lock ; and %1, %0" - : "=m"(*(int *)p) : "r"(v) : "memory" ); + : "=m"(*p) : "r"(v) : "memory" ); } static inline int a_swap(volatile int *x, int v) -- 2.40.0
