	gcc/ * builtins.c (fold_builtin_atomic_always_lock_free): Make "lock-free" conditional on existance of a fast atomic load. * optabs-query.c (can_atomic_load_p): New function. * optabs-query.h (can_atomic_load_p): Declare it. * optabs.c (expand_atomic_exchange): Always delegate to libatomic if no fast atomic load is available for the particular size of access. (expand_atomic_compare_and_swap): Likewise. (expand_atomic_load): Likewise. (expand_atomic_store): Likewise. (expand_atomic_fetch_op): Likewise. * testsuite/lib/target-supports.exp (check_effective_target_sync_int_128): Remove x86 because it provides no fast atomic load. (check_effective_target_sync_int_128_runtime): Likewise. libatomic/ * acinclude.m4: Add #define FAST_ATOMIC_LDST_. auto-config.h.in: Regenerate. * config/x86/host-config.h (FAST_ATOMIC_LDST_16): Define to 0.
