Commit Message

Fix data race in disclaim_weakmap_test statistic counters update
(fix of commit 6eba4218a)

Issue #239 (bdwgc).

The stat_* variables need to be atomically updated, since the locking
of the map is granular (cf WEAKMAP_MUTEX_COUNT) to allow parallelism
between different key hashes.

* tests/disclaim_weakmap_test.c [!AO_CLEAR] (AO_t): Define.
* tests/disclaim_weakmap_test.c [!AO_HAVE_fetch_and_add1]
(AO_fetch_and_add1): Define.
* tests/disclaim_weakmap_test.c (stat_added, stat_found, stat_removed,
stat_skip_marked, stat_skip_locked): Change type back from unsigned to
volatile AO_t.
* tests/disclaim_weakmap_test.c (weakmap_add, weakmap_disclaim):
Update stat_* counters using AO_fetch_and_add1(); move counters update
outside weakmap_lock/unlock block.
* tests/disclaim_weakmap_test.c (main): Cast stat_* counters to
unsigned type in printf() call.
