Behdad Esfahbod	333173103b	Fix sign of shift operators This one: map->mask = (1 << (next_bit + bits_needed)) - (1 << next_bit); before the fix, the shift was done as an int, causing overflow if it ever got to 1 << 31. Sprinkle 'u's around. Fixes https://bugs.chromium.org/p/chromium/issues/detail?id=634805	2016-08-08 17:28:14 -07:00

Behdad Esfahbod	e4b6d503c5	Don't use atomic ops in hb_cache_t We don't care about linearizability, so unprotected int read/write are enough, no need for expensive memory barriers. It's a cache, that's all.	2012-05-27 10:11:13 -04:00
Behdad Esfahbod	20fdb0f41d	Add a lock-free cache type for int->int functions To be used for cmap and advance caching if desired.	2012-05-17 22:04:45 -04:00
