From 1ea339b69725cb2f30b5a84cb7ca96111c9a637b Mon Sep 17 00:00:00 2001 From: Torvald Riegel Date: Sat, 18 Oct 2014 01:02:59 +0200 Subject: Add arch-specific configuration for C11 atomics support. This sets __HAVE_64B_ATOMICS if provided. It also sets USE_ATOMIC_COMPILER_BUILTINS to true if the existing atomic ops use the __atomic* builtins (aarch64, mips partially) or if this has been tested (x86_64); otherwise, this is set to false so that C11 atomics will be based on the existing atomic operations. --- sysdeps/i386/i486/bits/atomic.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'sysdeps/i386') diff --git a/sysdeps/i386/i486/bits/atomic.h b/sysdeps/i386/i486/bits/atomic.h index 76e0e8e2e3..739d3846f2 100644 --- a/sysdeps/i386/i486/bits/atomic.h +++ b/sysdeps/i386/i486/bits/atomic.h @@ -54,6 +54,9 @@ typedef uintmax_t uatomic_max_t; # endif #endif +#define __HAVE_64B_ATOMICS 0 +#define USE_ATOMIC_COMPILER_BUILTINS 0 + #define atomic_compare_and_exchange_val_acq(mem, newval, oldval) \ __sync_val_compare_and_swap (mem, oldval, newval) -- cgit 1.4.1
