So, here is a patch which splits the test into two, one tests just __int128 atomics, one tests long long atomics, on lp64 targets we can test both. And the effective targets are so that either the target has hw support of the atomics with no need of -latomic, or -latomic is available. 2026-09-30 Jakub Jelinek <[email protected]> PR middle-end/127492 * gcc.dg/pr127492.c: Require int128 effective target and either sync_int_128_runtime or libatomic_available. Drop the long long fallback, but define T only if it is not defined already. * gcc.dg/pr127492-2.c: New test.
