Behdad Esfahbod 6c15ddfe2b Renamed DEBUG to something else 
Some infrastructures use DEBUG as a generic symbol.

Behdad Esfahbod 00b93f6610 Fix icu linking by requesting the library searchpath from icu-config 
This is not ideal as we don't like -L/usr/lib in our linker line.
But this is only relevant to environments that don't have pkgconfig
files for ICU...

Behdad Esfahbod 06a44e8593 Remove unneeded code 
We always push a pause at the end such that each lookup falls in exactly
one pause_map_t.  Now, only if I can find a better name for that...

Behdad Esfahbod 0dc3a4e034 Obssesive optimization 
Not measurable by any means, but conceptually this is faster since
the mask matches more often than the digest.
 2013-04-17 23:04:03 -04:00
Behdad Esfahbod f9a6110267 Remove HB_DEBUG_SET_DIGESTS 
Wasn't correct with the new combiner.  I should add it back somehow,
but for now the digests seem to be working very well...

Behdad Esfahbod 0d5798a137 Improve hb_set_digest_t 
Make Amiri rendering faster a whopping 45% again!  Speends up pretty
much anything I tested.

Behdad Esfahbod 02e5e58368 Speed up Speed up hb_set_digest_common_bits_t calcs 
Correctly this time.
 2013-04-16 23:13:10 -04:00
Behdad Esfahbod 893991fc9d Initialize set digests 
We were not initializing the digests properly and as a result they were
being initialized to zero, making digest1 to never do any useful work.

Speeds up Amiri shaping significantly.

Behdad Esfahbod 1357c2dd12 Revert "Speed up hb_set_digest_common_bits_t calcs" 
This reverts commit 3d1b66a35e.

The calculations were buggy.  It's not worth optimizing right now.

Behdad Esfahbod 08677c2507 [old] Speed up Unicode properties access in hb-old shaper 
Just to be sure it's not punishing the old shaper performance
numbers.  Doesn't seem to have a measurable effect.

Behdad Esfahbod 587e5753e0 Add note re Hangul shaping 2013-04-05 12:38:58 -04:00
Behdad Esfahbod 269de14dda Don't compose Hangul jamo 
See thread "an issue regarding discrepancy between Korean and Unicode
standards" on the mailing list for the rationale.  In short: Uniscribe
doesn't, so fonts are designed to work without it.

Behdad Esfahbod 1f97060985 Put back MemoryBarrier fallback implementation on MINGW32 
This almost reverts 2761e8a632,
but only if under MINGW32, so it doesn't affect MSVC.
 2013-04-04 15:02:03 -04:00
Behdad Esfahbod f368ba4a9e [Arabic] Zero marks by GDEF, not Unicode category 
Testing shows that this is closer to what Uniscribe does.

Reported by Khaled Hosny:

"""
commit 568000274c
...
This commit is causing a regression with Amiri, the string “هَٰذ” with
Uniscribe and HarfBuzz before this commit, gives:

	[uni0630.fina=3+965|uni0670.medi=0+600|uni064E=0@-256,0+0|uni0647.init=0+926]

But now it gives:

	[uni0630.fina=3+965|uni0670.medi=0+0|uni064E=0@-256,0+0|uni0647.init=0+926]

i.e. uni0670.medi is zeroed though it has a base glyph GDEF class.
"""

The test case is U+0647,U+064E,U+0670,U+0630 with Amiri.
