Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 7c52c4f9 by John Paul Adrian Glaubitz at 2026-02-10T13:52:43-05:00 rts: Switch prim to use modern atomic compiler builtins The __sync_*() atomic compiler builtins have been deprecated in GCC for a while now and also don't provide variants for 64-bit values such as __sync_fetch_and_add_8(). Thus, replace them with the modern __atomic_*() compiler builtins and while we're at it, also drop the helper macro CAS_NAND() which is now no longer needed since we stopped using the __sync_*() compiler builtins altogether.
