Problem reported by Mickey Gabel <mickey@monfort.co.il>.

* src/base/ftobjs.c (FT_Get_FSType_Flags): Move to...
* src/base/ftfstype.c: This new file.

* modules.cfg (BASE_EXTENSION): Add ftfstype.c.

* docs/INSTALL.ANY: Updated.

* builds/mac/*.txt, builds/amiga/*makefile*,
builds/win32/{visualc,visualce}/freetype.*, builds/symbian/*:
Updated.

Werner Lemberg ce33a312da FT_USE_MODULE declares things as:
extern const FT_Module_Class

(or similar for C++).  However, the actual types of the variables
being declared are often different, e.g., FT_Driver_ClassRec or
FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)

This works with most C compilers (since those structs begin with an
FT_Module_Class struct), but technically it's undefined behavior.

To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
paragraph 2:

  All declarations that refer to the same object or function shall
  have compatible type; otherwise, the behavior is undefined.

(And they are not compatible types.)

Most C compilers don't reject (or even detect!) code which has this
issue, but the GCC LTO development branch compiler does.  (It
outputs the types of the objects while generating .o files, along
with a bunch of other information, then compares them when doing the
final link-time code generation pass.)

Patch from Savannah bug #25133.

* src/base/ftinit.c (FT_USE_MODULE): Include variable type.

* builds/amiga/include/freetype/config/ftmodule.h,
include/freetype/config/ftmodule.h, */module.mk: Updated to declare
pass correct types to FT_USE_MODULE.

Werner Lemberg 288ce14303 * builds/amiga/*: Added copyright notes, reworked some comments. 2005-06-08 11:56:55 +00:00
Werner Lemberg 92aa527a1c * builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk
(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove
-fno-strict-aliasing.


Say you have `(Foo*)x' and want to assign, pass, or return it as
`(Bar*)'.  If you simply say `x' or `(Bar*)x', then the C compiler
would warn you that type casting incompatible pointer types breaks
strict-aliasing.  The solution is to cast to `(void*)' instead which
is the generic pointer type, so the compiler knows that it should
make no strict-aliasing assumption on `x'.  But the problem with
`(void*)x' is that seems like in C++, unlike C, `void*' is not a
generic pointer type and assigning `void*' to `Bar*' without a cast
causes an error.  The solution is to cast to `Bar*' too, with
`(Bar*)(void*)x' as the result -- this is what the patch does.

* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),
include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove
cast on lvalue, use a temporary pointer instead.
Cast temporarily to (void*) to not break strict aliasing.

* include/freetype/internal/ftmemory.h (FT_MEM_ALLOC,
FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE),
src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*)
to not break strict aliasing.

* src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information.

* builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing.

* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c --
it is currently loaded from ttsbit.c.
