Subject: Test double_compare_and_swap in test_atomic
X-Git-Tag: libatomic_ops-7_4_0~108
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3acfd853578e81707cae75e3c1561d53a2d847c7;p=libatomic_ops

Test double_compare_and_swap in test_atomic

* tests/test_atomic_include.template (test_atomicXX): Define old_w
and new_w local variables (only if AO_HAVE_double_compare_and_swapXX);
add tests for AO_double_compare_and_swapXX if available.
