function from GNU inline assembly syntax (see #ifdef __GNUC__ block
above) to MASM syntax for Microsoft Visual C++.
 2011-02-14 08:32:24 +01:00

Werner Lemberg 18931a5a5d [truetype] FT_LOAD_PEDANTIC now affects `prep' and `fpgm' also. 
* src/truetype/ttgload.c (tt_loader_init): Handle
`FT_LOAD_PEDANTIC'.
* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep,
tt_size_init_bytecode, tt_size_ready_bytecode): New argument to
handle pedantic mode.
* src/truetype/ttobjs.h: Updated.
 2011-02-01 07:08:43 +01:00
Werner Lemberg f1a981b5ce [truetype] Protect jump instructions against endless loops. 
* src/truetype/interp.c (DO_JROT, DO_JMPR, DO_JROF): Exit with error
if offset is zero.
 2011-01-31 22:26:53 +01:00
Werner Lemberg d6a213f8ea [truetype] Improve handling of invalid references. 
* src/truetype/interp.c: Set even more TT_Err_Invalid_Reference
error codes only if pedantic hinting is active.  At the same time,
try to provide sane values which hopefully allow useful
continuation.  Exception to this is CALL and LOOPCALL – due to
possible stack corruption it is necessary to bail out.
 2011-01-31 18:51:07 +01:00
Werner Lemberg 96f0456483 [truetype] Improve handling of stack underflow. 
* src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP,
Ins_DELTAC): Exit with error only if `pedantic_hinting' is set.
Otherwise, try to do something sane.

LIU Sun-Liang c61b3596d4 [truetype]: Fix behaviour of MIAP for invalid arguments. 
* src/truetype/ttinterp.c (Ins_MIAP): Set reference points even in
case of error.
 2011-01-30 16:29:45 +01:00
Werner Lemberg 332da87d99 [autofit] Some formatting and clean-ups. 2011-01-23 12:42:23 +01:00
Werner Lemberg dcdb3167dc [truetype] Fix handling of MIRP instruction. 
Thanks to Greg Hitchcock who explained the issue.

* src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with
`>' since the description in the specification is incorrect.
This fixes, for example, glyph `two' in font `Helvetica Neue LT Com
65 medium' at 15ppem.
 2011-01-18 07:35:26 +01:00
suzuki toshiya 17f54bc66c Fix ARM assembly code in include/freetype/config/ftconfig.h. 
* include/freetype/config/ftconfig.h (FT_MulFix_arm):
Copy the maintained code from builds/unix/ftconfig.in.
Old GNU binutils could not accept the reduced syntax
`orr %0, %2, lsl #16'.  Un-omitted syntax like RVCT,
`orr %0, %0, %2, lsl #16' is better.  Reported by
Johnson Y. Yan.  The bug report by Qt developers is
considered too.

 2011-01-15 21:53:32 +09:00
Werner Lemberg 21bdca7907 [raster] Make bbox handling the same as with Microsoft's rasterizer. 
Right before B/W rasterizing, the bbox gets simply rounded to
integers.  This fixes, for example, glyph `three' in font `Helvetica
Neue LT Com 65 Medium' at 11ppem.

Thanks to Greg Hitchcock who explained this behaviour.

* src/raster/ftrend1.c (ft_raster1_render): Implement it.
 2011-01-15 09:46:13 +01:00
suzuki toshiya a2ef6647ae Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS. 
* builds/unix/configure.raw: Consider recent gcc-standard
flags to specify architecture in CFLAGS & LDFLAGS
harmonization.  Requested by Savannah bug #32114, to
support multilib feature of BuildRoot SDK correctly.
 2011-01-15 13:33:28 +09:00
suzuki toshiya c68a82d8fc Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer. 
* builds/unix/configure.raw: Some important options that
included in CFLAGS but not in LDFLAGS are copied to
LDFLAGS, but the last option in CFLAGS was not checked.
 2011-01-15 13:21:32 +09:00
Werner Lemberg 0039d0120e [raster] Add undocumented drop-out rule to the other bbox side also.
