	1c249be9	2024-12-02T15:51:19		Sidestep nontrivial-memaccess warning in Crap() With -Wnontrivial-memaccess, recent versions of clang flag the usage of memcpy in hb-null.hh with pointers to nontrivially-copyable types. Sidestep this warning by casting the problematic pointer to void*.
	56e8a290	2023-08-22T15:49:00		Fix static_size declaration I have a vague memory that it was intentionally written that way, but I can't recall :-(.
	60db1427	2023-07-24T20:49:32		[layout] Remove unused "max-size" cruft
	c91899be	2023-07-21T11:43:47		[gdef] Use set-digest for mark-filterint-sets Speeds up Noto Duployan-Regular.otf by 45% percent!
	2006d321	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...
	7a85663c	2023-07-07T19:21:18		Revert "[sanitize] Add "fastpath" for ArrayOfOffset16To<> objects with max size" This reverts commit 10f8556c73f3cf231c6b5a900a6a1903f9516f90. This was, unfortunately, wrong :(.
	10f8556c	2023-07-07T17:07:11		[sanitize] Add "fastpath" for ArrayOfOffset16To<> objects with max size

	8df9aba9	2022-05-26T03:59:21		Actually try to fix null-size undefined behavior Related to: https://github.com/harfbuzz/harfbuzz/pull/2067 https://bugzilla.mozilla.org/show_bug.cgi?id=1577584
	23a28f5a	2021-04-16T13:22:05		Avoid undefined-behavior If a struct had (because it's a union) sizeof that is larger than the null_size, we were providing only null_size bytes for its Null object. We know we'd never access beyond that, but is undefined-behavior nonetheless according to the standard. The alternative fix would have required use of flexible-arrays, which are not standard and have their own issues in various compiler. We've discussed that extensively in the follow Mozilla issue (currently locked; I've asked that it be opened): https://bugzilla.mozilla.org/show_bug.cgi?id=1577584 Part of https://github.com/harfbuzz/harfbuzz/pull/2067
	499248c5	2021-04-16T13:14:48		[blob] Use min_size, instead of null_size in .as<T>() Part of https://github.com/harfbuzz/harfbuzz/pull/2067
	53806e5b	2020-11-25T11:51:37		Tiny improvement on previous commit Functionally the same.
	bd8aa1b0	2020-04-21T22:19:46		Minor
	2dda6dd7	2020-04-20T14:12:45		minor, tweak spacing turn 8 spaces to tab, add space before Null/Crap
	3aceee25	2019-09-06T12:17:18		Revert "[null] Silence undefined-behavior complaints with too-small null bytes" This reverts commit 911c76abcdfe89770b252eb0d4eb621c0db00ad5. Broke tests. I'm not sure I understand why. At any rate, this was a bad way to fix. I'll look into understanding as well as better fix.

	60653a7a	2019-06-18T13:01:11		Remove HB_VECTOR_SIZE It was cumbersome to get it to work reliably, for dubious performance gain, mostly in the subsetter maybe... Life is easier without. It was disabled forever anyway.
	c0485e32	2019-05-10T21:03:14		Use hb_void_t<> the way it's supposed to be used
	5a171ed3	2019-05-10T20:11:29		[null] Modernize template work

	4c38a9f6	2019-03-29T20:23:07		Remove hb_assign() Not needed anymore. We just use operator= now.
	b986c6a3	2019-03-29T20:17:46		[C++11] Remove IntType::set() in favor of operator=
	ea281aa8	2019-03-26T16:18:03		Use class templates for Null objects This allows partial-instantiating custom Null object for template Lookup<T>. Before, this had to be handcoded per instantiation. Apparently I missed adding one for AAT::ankr.lookupTable, so it was getting the wrong (generic) null for Lookup object, which is wrong and unsafe. Fixes https://bugs.chromium.org/p/chromium/issues/detail?id=944346
	a030ce4f	2019-03-28T21:26:50		Merge branch 'master' into iter

	2737aa81	2018-11-22T01:44:27		Fix up recent change Fixes https://github.com/harfbuzz/harfbuzz/issues/1300
	f2b91d65	2018-11-22T01:10:22		Use Type::null_size for our structs in Null(), sizeof() for other types
	8d778877	2018-11-21T23:46:09		..
	55c66c7c	2018-11-11T16:09:38		Revert "Declare Null() constexpr" This reverts commit 442a72d95ab1fb3a47b486d8d1eb68e909d0ffb8. Doesn't make sense. No idea how my local compilers where happy with it!

	606bf574	2018-09-16T19:33:48		Revert forcing use of single-parameter static_assert() Some clang versions define static_assert as a macro apparently, so we cannot redefine it... This reverts commit 94bfea0ce6a7b4d5641c198d50751748a353df11. This reverts commit 4e62627831e7457ed60ff87712570065b14b200a.
