Improve atomic store implementation on hppa-linux.
2021-12-27 John David Anglin <danglin@gcc.gnu.org>
gcc/ChangeLog:
* config/pa/pa-protos.h: Delete
pa_maybe_emit_compare_and_swap_exchange_loop() declaration.
* config/pa/pa.c (pa_expand_compare_and_swap_loop): Delete.
(pa_maybe_emit_compare_and_swap_exchange_loop): Delete.
* config/pa/pa.md (atomic_storeq): Use __sync_lock_test_and_set
instead of pa_maybe_emit_compare_and_swap_exchange_loop.
(atomic_storehi, atomic_storesi, atomic_storedi): Likewise.
