Behdad Esfahbod c7378294 2025-02-06T01:42:25 [OT] Remove likely() from coverage check Not that it matters, but because of the set-digest, this path is not very likely() anymore.

Behdad Esfahbod 31949636 2023-05-04T16:29:48 Revert "[layout] Cache subtable coverages in hb_map_t" This reverts commit 7a715d74e06720c17d28ba7b4c3da0b583f8d1d3.
Behdad Esfahbod 7a715d74 2023-05-04T16:28:11 [layout] Cache subtable coverages in hb_map_t Proof-of-concept. Going to revert. Memory consumption is more than I like. It does speed up Roboto shaping another 15% though. Perhaps if we could add logic to choose which subtables to cache, this might be a useful approach.
