suzuki toshiya e2d2b1544f [ftrfork] Fix the face order difference between POSIX and Carbon.
The fragmented resources in Suitcase and .dfont should be reordered
when post resource for Type1 is being restored, but reordering of
sfnt resources induces the different face order.  Now the ordering
is restricted to post resource only, to prevent the different order
issue  (e.g. the face index in the fontconfig cache generated with
Carbon framework is incompatible with that by FreeType2 without
Carbon framework.)  Found by Khaled Hosny and Hin-Tak Leung.

Werner Lemberg 1924134710 Introduce `coverages'.
Coverages are the interface to the HarfBuzz library to access
OpenType features for handling glyphs not addressable by the cmap.

Right now, compilation of HarfBuzz is only added to the development
build.  A solution for standard build mode will be delayed until
HarfBuzz gets split into two libraries to avoid mutual dependencies
between FreeType and HarfBuzz.

Note that this is only a first step in handling coverages, basically
providing the framework only.  Code for handling selected OpenType
features (this is, actually using the data in `afcover.h') will
follow.

* devel/ftoption.h, include/config/ftoption.h
(FT_CONFIG_OPTION_USE_HARFBUZZ): New macro.

* src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h:
New files.

* src/autofit/afscript.h: Add HarfBuzz script name tags.

* src/autofit/afstyles.h: Add default coverage enumeration values.

* src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros.
(AF_Coverage): New enumeration (generated by `afcover.h').
(AF_StyleClassRec): New member `coverage'.
(AF_DEFINE_STYLE_CLASS): Updated.

* include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage
data.

* src/autofit/afglobal.h: Update use of `SCRIPT' and `STYLE' macros.
(AF_SCRIPT_FALLBACK): Renamed to ...
(AF_STYLE_FALLBACK): ... this.

* src/autofit/afglobal.c: Include `hbshim.c'.
Update use of `SCRIPT' and `STYLE' macros.
(af_face_globals_compute_style_coverage)
[FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'.
Update.

* src/autofit/afmodule.h (AF_ModuleRec):
s/fallback_script/fallback_style/.

* src/autofit/afmodule.c (af_property_set): Adapt handling of
`fallback-script' property to set a fallback style.
(af_property_get, af_autofitter_init): Updated.

* src/autofit/afpic.c: Update use of `SCRIPT' and `STYLE' macros.

* src/autofit/afranges.h: Update use of `SCRIPT' macro.

* src/autofit/autofit.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: Include

all libraries needed by FreeType.

function name correctly corresponds to what the macro framework
expects.

* src/psnames/rules.mk (PSNAMES_DRV_SRC_S): Use correct file name so

Werner Lemberg fae3820764 Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level.  Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.

Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like

  #include <ft2build.h>
  #include FT_FREETYPE_H
  ...

don't need any change to the source code.

* include/freetype/*: Move up to...
* include/*: ... this directory.

* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.

*/*: Essentially do `s@/freetype/@/@' where appropriate.

* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.

Chongyu Zhu 41632b58ef [arm] Fix thumb2 inline assembly under LLVM.
When using `ADD' with an immediate operand, the instruction is
actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the
immediate operand cannot exceed 4095.  It will fail to compile with
LLVM.

However, in GCC, due to some legacy compatibility considerations,
`ADD.W' will be automatically emitted when the immediate operand is
larger than 4095.
