From 57977c4bf379c7f0b3dcf8b9a97a76214bfdf677 Mon Sep 17 00:00:00 2001 From: Will Newton Date: Fri, 4 Jul 2014 16:10:15 +0100 Subject: ARM: Fix compiler warnings from atomic.h __arch_compare_and_exchange_bool_*_int return a boolean so in the dummy implementations for 8, 16 and 64 bits return zero rather than oldval. Zero is used rather than TRUE or FALSE to avoid needing to including any headers for these dummy functions. ChangeLog: 2014-07-17 Will Newton * sysdeps/arm/bits/atomic.h (__arch_compare_and_exchange_bool_8_int): Evaluate to zero. (__arch_compare_and_exchange_bool_16_int): Likewise. (__arch_compare_and_exchange_bool_64_int): Likewise. --- sysdeps/arm/bits/atomic.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'sysdeps/arm') diff --git a/sysdeps/arm/bits/atomic.h b/sysdeps/arm/bits/atomic.h index c2d5be5..88cbe67 100644 --- a/sysdeps/arm/bits/atomic.h +++ b/sysdeps/arm/bits/atomic.h @@ -96,10 +96,10 @@ void __arm_link_error (void); For all "bool" routines, we return FALSE if exchange succesful. */ # define __arch_compare_and_exchange_bool_8_int(mem, newval, oldval, model) \ - ({__arm_link_error (); oldval; }) + ({__arm_link_error (); 0; }) # define __arch_compare_and_exchange_bool_16_int(mem, newval, oldval, model) \ - ({__arm_link_error (); oldval; }) + ({__arm_link_error (); 0; }) # define __arch_compare_and_exchange_bool_32_int(mem, newval, oldval, model) \ ({ \ @@ -109,7 +109,7 @@ void __arm_link_error (void); }) # define __arch_compare_and_exchange_bool_64_int(mem, newval, oldval, model) \ - ({__arm_link_error (); oldval; }) + ({__arm_link_error (); 0; }) # define __arch_compare_and_exchange_val_8_int(mem, newval, oldval, model) \ ({__arm_link_error (); oldval; }) -- cgit v1.1
