Ben Wagner 7819aeb6 2017-06-28T22:57:41 Avoid Microsoft compiler warnings (#51331). While clang's sanitizer recommends a cast to unsigned for safe negation (to handle -INT_MIN), both MSVC and Visualc emit warning C4146 if an unsigned value gets negated. * include/freetype/internal/ftcalc.h (NEG_LONG, NEG_INT32), src/base/ftcalc.c (FT_MOVE_SIGN): Replace negation with a subtraction.
Werner Lemberg dde8f5ab 2017-06-27T06:16:04 [truetype] Integer overflows. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2384 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2391 * src/base/ftcalc.c (FT_MulDiv, FT_MulDiv_No_Round, FT_DivFix): Use NEG_LONG. * src/truetype/ttinterp.c (Ins_SxVTL): Use NEG_LONG.

Werner Lemberg dcd8de27 2017-06-09T11:21:58 */*: Remove `OVERFLOW_' prefix. This increases readability.
Werner Lemberg fbe2fe4c 2017-05-29T13:29:28 Handle some integer overflow run-time errors (#46149, #48979). This commit (mainly for 32bit CPUs) is the first of a series of similar commits to handle known integer overflows. Basically, all of them are harmless, since they affect rendering of glyphs only, not posing security threats. It is expected that fuzzying will show up more overflows, to be fixed in due course. The idea is to mark places where overflows can occur, using macros that simply cast to unsigned integers, because overflow arithmetic is well defined in this case. Doing so suppresses run-time errors of sanitizers without adding computational overhead. * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, ft_corner_orientation): Use new macros. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros.
Werner Lemberg 93572190 2017-05-28T07:20:09 Fix negation of INT_MIN and LONG_MIN (#46149). * src/base/ftcalc.c (FT_MOVE_SIGN): Add argument to pass unsigned value, to be used as the result. (FT_MulDiv, FT_MulDiv_No_Round, FT_DivFix, FT_MulFix, FT_Vector_NormLen): Updated.

Alexei Podtelezhnikov 7e6c321a 2015-08-03T23:26:13 [base] Fix `ft_corner_orientation'. Remove casting from `FT_Long' to `FT_Int' that might change the sign of the return value and make it faster too. * src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay with 32-bit arithmetic when safe.

Alexei Podtelezhnikov 884e4e67 2015-06-29T22:32:05 [base] Implement fast vector normalization. The function uses Newton's iterations instead of dividing vector components by its length, which needs a square root. This is, literally, a bit less accurate but a lot faster. * src/base/ftcalc.c (FT_Vector_NormLen): New function.

This optimization is especially noticeable for smaller dividends that barely use the high register. * src/base/ftcalc.c (ft_div64by32): Updated.

Alexei Podtelezhnikov 7f49111f 2014-09-25T22:54:38 [base] Avoid unnecessary long division. This applies to `FT_MulDiv' but not to `FT_DivFix', where overflows or lack thereof are predicted accurately. * src/base/ftcalc.c (ft_div64by32): Improve readability. (FT_MulDiv, FT_MulDiv_No_Round) [!FT_LONG64]: Use straight division when multiplication stayed within 32 bits.

Werner Lemberg 059bc335 2013-03-14T10:27:35 */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
Werner Lemberg 30f1e6ca 2013-02-01T14:50:08 Fix Savannah bug #38221. This complements commit 83c0ebab. * src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with `TT_USE_BYTECODE_INTERPRETER'.

Also provide an assembler implementation for ARM architectures. this is done to speedup FreeType a little (on x86 3% when loading+hinting, 10% when rendering, ARM savings are more important though). Disable this by undefining FT_CONFIG_OPTION_INLINE_MULFIX in ftconfig.h

It is used to provide global hinting data for both the top-font and all subfonts (with proper scaling). * src/cff/cffobjs.c (cff_make_private_dict): New function, using code from `cff_size_init'. (cff_size_init, cff_size_done, cff_size_select, cff_size_request): Use CFF_Internal and handle subfonts. (cff_face_init): Handle top-dict and subfont matrices correctly; apply some heuristic in case of unlikely matrix concatenation results. This has been discussed with people from Adobe (thanks goes mainly to David Lemon) who confirm that the CFF specs are fuzzy and not correct. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument. * src/cff/cffgload.c (cff_builder_init): Updated.

Werner Lemberg 913a3650 2006-11-19T09:19:17 Because FT_Load_Glyph expects CID values for CID-keyed fonts, the test for a valid glyph index must be deferred to the font drivers. This patch fixes Savannah bug #18301. * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c (FNT_Load_Glyph): Check validity of `glyph_index'.
Werner Lemberg 111b5aef 2006-11-03T09:40:12 * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'. Formatting
David Turner effd15de 2006-11-02T17:21:02 - merging af_corner_XXX and psh_corner_XXX functions into ft_corner_XXX versions in ftcalc.c - more auto-fitter debugging support
David Turner 6aa260ce 2006-08-25T22:45:13 support for "automatic unpatented hinting" added we still need to determine the list of "trick" CJK fonts that are going to toggle the bytecode interpreter instead of the auto-hinter
Werner Lemberg 545c4e56 2006-05-17T22:55:04 * src/truetype/ttgload.c (TT_Load_Composite_Glyph) [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again. Formatting, documentation fixes.
David Turner 281679de 2006-05-17T13:34:21 * include/freetype/internal/tttypes.h, src/autofit/afangles.c, src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c, src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c, src/type1/t1gload.c: this is a major patch used to drastically improve the performance of loading glyphs. This both speeds up loading the glypn vector themselves and the auto-fitter. note that we've started using inline assembler with GCC to implement FT_MulFix, given that this function is so damn important for the engine's performance. the resulting speed-up is about 25%.
Werner Lemberg 8e6f8c4d 2006-02-17T08:07:09 Formatting, copyright years, documentation improvements.
