Jouk Jansen ba7eb5be 2025-08-30T20:34:36 Clean up OpenVMS support. This avoids cluttering the source code with VMS-specific changes. * include/freetype/internal/ftcalc.h [__VMS], src/base/ftcalc.c [vms_auto64_source]: Remove. * builds/vms/patch_ftcalc.sed: New file. * vms_make.com: Change macro definitions while this script is running; we use `GNU sed` to inject the necessary preprocessor code on the fly.
Jouk Jansen aa2ee67b 2025-08-05T17:34:09 Improvements to OpenVMS support. * include/freetype/internal/ftcalc.h [__VMS]: Undefine `FT_MulFix`. * src/base/ftcalc.c [vms_auto64_source]: Define `FT_MulFix`. * vms_make.com: Also create 32bit version of the FreeType library.
Werner Lemberg e07e56c7 2025-05-26T17:20:12 [gxvar] Speed up handling of deltas in `ItemVariationStore`. (3/3) * src/base/ftcalc.c (FT_MulAddFix): Removed, no longer needed. * include/freetype/internal/ftcalc.h: Updated.
Behdad Esfahbod 8eae0399 2025-05-26T08:16:53 Lift `FT_Int64` type to global (internal) FreeType use. * src/base/ftcalc.c (FT_Int64) [!FT_INT64]: Move declaration to... * include/freetype/config/integer-types.h: ... this file. (FT_UInt64) [!FT_INT64]: New structure. (FT_INT64_ZERO): New macro.
Alexei Podtelezhnikov 4fad257a 2025-04-17T22:32:21 * src/base/ftcalc.c (ft_corner_orientation) [!FT_INT32]: Fix up.
Alexei Podtelezhnikov 0a650e8c 2025-04-16T22:54:54 * src/base/ftcalc.c: Miscellaneous cleanups.
Alexei Podtelezhnikov 8f67545d 2025-04-09T13:37:23 [base] Update FT_MulFix inlining. Resolves inconsistencies in 64-bit multiplication discussed in !355. Importantly, FT_MulFix arguments and return value is FT_Long, whatever sizeof FT_Long is on 64-bit platforms: 8 bytes on Linux or 4 bytes on Windows. * include/freetype/internal/ftcalc.h (FT_MulFix_x86_64): Removed. (FT_MulFix_64): Generalize and prioritize the inline implementation for all 64-bit platforms ifdef FT_INT64. * src/base/ftcalc.c (FT_MulFix)[FT_INT64]: Call 'FT_MulFix_64'. * src/base/ftbase.c: Include 'ftcalc.c' after the FT_MulFix callers to enable its inlining.

Alexei Podtelezhnikov 95b0fe2a 2023-09-19T22:26:32 [base] Reintroduce `FT_SqrtFixed`. The general square root calculations are not necessary in FreeType. For vector normalization or length, FreeType uses special functions. It is, however, required in the legacy CFF specifications. * src/base/ftcalc.c (FT_SqrtFixed): New function that uses either Babylonian or bit-wise algorithm, whichever is faster for the given situation. * include/freetype/internal/ftcalc.h (FT_SqrtFixed): Declare it.

Dominik Röttsches bec4ef41 2022-07-01T12:04:28 [base] Round values in `FT_MulAdd_Fix`. This avoids regressing Blink layout tests and makes `FT_MulAdd_Fix` delta retrieval implementation consistent with the previous implementation, which used `FT_fixedToInt` and included rounding. * src/base/ftcalc.c (FT_MulAdd_Fix): Implement it. Also fix remaining `temp` initialization compilation issue. Fixes #1169.
Dominik Röttsches 0607e0e9 2022-06-30T10:55:50 Fix initialisation of temp variable in new FT_MulAddFix src/truetype/ttgxvar.c (FT_MulAddFix): Initialise `temp`.
Dominik Röttsches 15fef219 2022-06-29T11:48:10 New function `FT_MulAddFix` to compute the sum of fixed-point products. This function, based on the code of `FT_MulFix`, uses 64-bit precision internally for intermediate computations. * include/freetype/internal/ftcalc.h, base/ftcalc.c (FT_MulAddFix): Implement it.

David Turner e1339133 2020-06-08T13:31:55 Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

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 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.

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.

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

Werner Lemberg fb09a51f 2013-08-04T18:24:02 Add comments to `ft_corner_is_flat'.
Werner Lemberg b112fa41 2013-05-12T07:29:04 Fix Savannah bug #38967. * src/base/ftcalc.c (FT_DivFix) [FT_LONG64]: Fix cast.
Werner Lemberg f6aa089f 2013-05-10T07:58:47 */* [FT_CONFIG_OPTION_OLD_INTERNALS]: Remove macro and guarded code.
Werner Lemberg d135e27c 2013-05-05T10:44:21 Fix 64bit compilation issues. * include/freetype/config/ftconfig.h [FT_LONG64]: Typedef `FT_Int64' here. * src/base/ftcalc.c: Remove typedef of `FT_Int64'. (FT_DivFix): Fix cast. * src/base/fttrigon.c: Remove typedef of `FT_Int64'.
Werner Lemberg 94152819 2013-05-04T16:40:12 More fixes for clang's `sanitize' feature. * src/base/ftcalc.c (FT_DivFix): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate, FT_Vector_Length, FT_Vector_Polarize): Ditto. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify. * src/cff/cffload.c (cff_subfont_load): Fix constant. * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed, cff_parse_fixed_dynamic): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/cid/cidload.c (cid_get_offset): Ditto. * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto.
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.
