Subject: [PATCH] Fix GCC 5.x compatibility for AArch64 double-wide primitives
|
|
|
|
Small change to make aarch64 support work with gcc 5.x. Otherwise it
|
|
demands gcc -latomic and still fails test_stack.
|
|
|
|
* src/atomic_ops/sysdeps/gcc/aarch64.h (AO_double_load,
|
|
AO_double_load_acquire, AO_double_store, AO_double_store_release,
|
|
AO_double_compare_and_swap, AO_double_compare_and_swap_acquire,
|
|
AO_double_compare_and_swap_release, AO_double_compare_and_swap_full):
|
|
Use assembly implementation even for GCC v5+ (not just GCC 4.x).
