	68b78914	2023-07-07T17:07:11		[sanitize] Add "fastpath" for ArrayOfOffset16To<> objects with max size Unfortunately this doesn't speed up NotoNastaliq or Gulzar as I was hoping for. Their GSUB tables are not large enough for this to kick in...

	b57ea3b0	2022-08-05T14:29:27		Revert "[iter] Use && in uses of is_source_of" This reverts commit ccbba667a9bdc096f0053d5e3ee951a8b6298e8a.
	ccbba667	2022-08-05T11:51:51		[iter] Use && in uses of is_source_of
	91c60802	2022-07-18T22:24:28		[open-type] Fix overflow check Without the cast, the compiler is within its rights to reason that overflow didn't happen and optimize away the check, as clang was.
	f0707e23	2022-07-17T16:47:16		[atomic] Add compiler memory_r_barrier https://github.com/harfbuzz/harfbuzz/issues/3728
	f3151b65	2022-07-17T16:19:28		[ArrayOf family] Use memory barrier before accessing array Without it, the compiler was reordering and batching the read of array length and array[0] if the 0'th member was accessed constantly and function was inlined. This felt safe to the compiler because HB_VAR_ARRAY is 1, but could be unsafe actually. The memory barrier disallows that. This was found by afl/honggfuzz address sanitizers. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=49187
	9843f076	2022-07-15T16:03:55		[OffsetTo] Try catching nullable offsets to unbounded types Doesn't catch all cases; if type is not fully defined at OffsetTo time, we can't know. Fixes https://github.com/harfbuzz/harfbuzz/issues/1300 to the best we can do.

	7c4e9080	2022-07-11T14:01:52		[sanitize] Minor trace format fixup This likely() is unlikely to make a difference, and obscures the return_trace() message by writing out "something" instead of the true/false value.
	2c672617	2022-07-06T12:26:16		[open-type] Add HBGlyph24
	486555c6	2022-07-05T17:12:59		[open-type] Add Array24Of<> and SortedArray24Of<>
