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/tile/tilepro/bits/atomic.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'sysdeps/tile/tilepro') diff --git a/sysdeps/tile/tilepro/bits/atomic.h b/sysdeps/tile/tilepro/bits/atomic.h index cbbf64cef1..c3865bee2f 100644 --- a/sysdeps/tile/tilepro/bits/atomic.h +++ b/sysdeps/tile/tilepro/bits/atomic.h @@ -21,6 +21,9 @@ #include +#define __HAVE_64B_ATOMICS 0 +#define USE_ATOMIC_COMPILER_BUILTINS 0 + /* 32-bit integer compare-and-exchange. */ static __inline __attribute__ ((always_inline)) int __atomic_cmpxchg_32 (volatile int *mem, int newval, int oldval) -- cgit 1.4.1
