079a724833 [libpng16] Fixed some nits in contrib/arm-neon/README and comments in 
contrib/examples/*.c

0b61d10ad4 [libpng16] Fixed /proc/cpuinfo ARM NEON __linux__ parsing 2014-02-16 14:07:49 -06:00
John Bowler
dba54b8888 [libpng16] Moved OS dependent code from arm/arm_init.c, to allow the included 
implementation of the ARM NEON discovery function to be set at
build-time and provide sample implementations from the current code in the
contrib/arm-neon subdirectory. The __linux__ code has also been changed to
compile and link on Android by using /proc/cpuinfo, and the old linux code
is in contrib/arm-neon/linux-auxv.c.  The new code avoids POSIX and Linux
dependencies apart from opening /proc/cpuinfo and is C90 compliant.

1fc0171278 [libpng16] Revised pngvalid.c to support libpng 1.5, which does not support the 
PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in
pngvalid.c

0f6303301f [libpng16] Fixed pngvalid 'fail' function declaration on the Intel C Compiler. 
This reverts to the previous 'static' implementation and works round
the 'unused static function' warning by using PNG_UNUSED().

503a49458b [libpng16] Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder. 2013-11-22 15:16:04 -06:00
Glenn Randers-Pehrson
c912050a7b [libpng16] Fixed 'minimal' builds. Various obviously useful minimal 
configurations don't build because of missing contrib/libtests test programs
and overly complex dependencies in scripts/pnglibconf.dfa. This change adds
contrib/conftest/*.dfa files that can be used in automatic build
scripts to ensure that these configurations continue to build.

a7f0bcb3a6 [libpng16] Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile 2013-11-18 17:07:26 -06:00
John Bowler
08b0620202 [libpng16] Fixed #include in filter_neon_intrinsics.c and ctype macros. The 
ctype char checking macros take an unsigned char argument, not a signed char.

9e9977e153 [libpng16] Revised pngvalid to generate size images with as many filters as 
it can manage, limited by the number of rows.

236e105170 [libpng16] Simplified error message code in pngunknown. The simplification has 
the useful side effect of avoiding a bogus warning generated by the latest
version of the Intel C compiler (it objects to
condition ? string-literal : string-literal).
 2013-10-04 20:28:33 -05:00
John Bowler
5b1df53a82 [libpng16] Cleaned up (char*) casts of zlib messages. The latest version of 
the Intel C compiler complains about casting a string literal as (char*), so
copied the treatment of z_const from the library code into pngfix.c
 2013-10-04 20:13:17 -05:00

cc93d89e43 [libpng16] Updated pngunknown.c 2013-09-30 13:07:58 -05:00
John Bowler
8f381901e3 [libpng16] Avoid up-cast warnings in pngvalid.c. On ARM the alignment 
requirements of png_modifier are greater than that of png_store and as a
consequence compilation of pngvalid.c results in a warning about increased
alignment requirements because of the bare cast to (png_modifier*). The code
is safe, because the pointer is known to point to a stack allocated
png_modifier, but this change avoids the warning.

  Fixed default behavior of ARM_NEON_API. If the ARM NEON API option was
    compiled without the CHECK option it defaulted to on, not off.

  Check user callback behavior in pngunknown.c. Previous versions compiled
    if SAVE_UNKNOWN was not available but did nothing since the callback
    was never implemented.

  Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes
 2013-09-30 11:24:17 -05:00
John Bowler
15a80443de [libpng16] Allow HANDLE_AS_UNKNOWN to work when other options are configured 
off. Also fixed the pngminim makefiles to work when $(MAKEFLAGS) contains stuff
which terminates the make options (as by default in recent versions of Gentoo).

b4ec1f8451 [libpng16] Unified pngfix.c source with libpng17. 2013-07-02 23:47:57 -05:00
John Bowler
f5f1206778 [libpng16] Fixed undefined behavior in contrib/tools/pngfix.c and added new 
strip option. pngfix relied on undefined behavior and even a simple change from
gcc to g++ caused it to fail.  The new strip option 'unsafe' has been
implemented and is the default if --max is given.  Option names have
been clarified, with --strip=transform now stripping the bKGD chunk,
which was stripped previously with --strip=unused.
Added all documented chunk types to pngpriv.h

573c9d434f [libpng16] Change "png-fix-too-far-back" to "pngfix" inside pngfix.c

correctly.

3f2b5a6670 libpng16] Updated contrib/pngminus/pnm2png.c (Paul Stewart):

Initialize dimension values so if sscanf fails at least we have known
   invalid values.
