2021-03-23libpng: optimize for speed on Arm platformsHEADlineage-18.1Jonathan Wright
Change libpng build configuration to optimize for speed on Arm platforms. This allows the compiler to inline some of the NEON filter functions and significantly increase performance. Binary size increase is minimal (<10KB increase in normalized Android APK size.)

(Modelled after libjpeg-turbo in I12305d5136ef98b2e768ddfdc4b60b8d3c088965.) This will help us to automatically update this library to newer releases upstream using tools/external_updater. Remove README.version, which is redundant and no longer used. Update README.android to be less redundant and include other additions.

2019-04-10pngminus: Use the system zlib by defaultCosmin Truta
If a zlib source tree exists besides the libpng source tree in the same parent directory, the pngminus build may fail, unless the zlib tree is built fully. In order to avoid this failing scenario, do not use the custom-built zlib by default. (The custom-built zlib is still necessary on platforms that lack a system-built zlib.)
2019-04-10pngminus: Change license to MIT, etc.Willem van Schaik
Change the license to MIT. Move the license text from the source files to a LICENSE file. Move the change log from the source files to a CHANGES file. Delete the Turbo C makefile and simplify the Linux makefile heavily. Create explicitly named static and shared executables in the makefile. Refresh the README file a bit from the twenty year old one.

2019-04-07arm: Partially revert "Fix a memory leak in the riffled palette [...]"Cosmin Truta
The memory leak remains fixed, but the associated refactoring is being reverted. Moving the initialization of the riffled palette from png_do_read_transformations to png_init_palette_transformations has caused a regression in some of the test programs. Although png_init_palette_transformations is the proper place to perform this initialization, and the test programs are technically incorrect to fail, we are still undoing that refactoring for the time being.

2019-02-03Call png_image_free_function without guarding it with png_safe_executeCosmin Truta
png_image_free_function (or any other destructor) should never fail. Destructors need not and must not be executed under png_safe_execute. Reference: CVE-2019-7317, use-after-free in png_image_free
2019-02-03Fix a memory leak in pngtest.cCosmin Truta
Ensure that row_buf is deallocated not only after a read error, but also after a write error. Use the format "%p" instead of "0x%08lx" for printf-ing row_buf in a portable manner.
2019-02-03Fix a memory leak in the riffled palette optimization on ARM; refactorCosmin Truta
Move deallocation of riffled_palette from png_write_destroy to png_read_destroy. The reader (not the writer) is the owner of riffled_palette. Move allocation and initialization of riffled_palette from png_do_read_transformations to png_init_palette_transformations. Allow riffled_palette inside png_struct only if the ARM Neon optimizations are enabled. Rename png_riffle_palette_rgba to png_riffle_palette_rgba8, etc., to better indicate the strict applicability of these routines. Fix an unused parameter warning in the build configurations where riffled palette optimization is not enabled. Fix indentation.
