(build_call_expr_internal_loc_array): ... this. Fix up type of last argument. * internal-fn.def (ATOMIC_COMPARE_EXCHANGE): New internal fn. * predict.c (expr_expected_value_1): Handle IMAGPART_EXPR of ATOMIC_COMPARE_EXCHANGE result. * builtins.h (expand_ifn_atomic_compare_exchange): New prototype. * gimple-fold.h (optimize_atomic_compare_exchange_p, fold_builtin_atomic_compare_exchange): New prototypes. * gimple-fold.c (optimize_atomic_compare_exchange_p, fold_builtin_atomic_compare_exchange): New functions.. * tree-ssa.c (execute_update_addresses_taken): If optimize_atomic_compare_exchange_p, ignore &var in 2nd argument of call when finding addressable vars, and if such var becomes non-addressable, call fold_builtin_atomic_compare_exchange.
