option:
--enable-arm-neon=always will stop the run-time checks. New checks
within arm/arm_init.c will cause the code not to be compiled unless
__ARM_NEON__ is set. This should make it fail safe (if someone asks
for it on then the build will fail if it can't be done.)
Fixed ALIGNED_MEMORY support.

Changes since the last public release (1.6.0):
|
|
|
|
Version 1.6.1beta01 [February 16, 2013]
|
|
Made symbol prefixing work with the ARM neon optimizations. Also allow
|
|
pngpriv.h to be included for preprocessor definitions only, so it can
|
|
be used in non-C/C++ files. Back ported from libpng 1.7.
|
|
Made sRGB check numbers consistent.
|
|
Ported libpng 1.5 options.awk/dfn file handling to 1.6, fixed one bug.
|
|
Removed cc -E workround, corrected png_get_palette_max API Tested on
|
|
SUN OS cc 5.9, which demonstrates the tokenization problem previously
|
|
avoided by using /lib/cpp. Since all .dfn output is now protected in
|
|
double quotes unless it is to be macro substituted the fix should
|
|
work everywhere.
|
|
Enabled parallel tests - back ported from libpng-1.7.
|
|
scripts/pnglibconf.dfa formatting improvements back ported from libpng17.
|
|
Fixed a race condition in the creation of the build 'scripts' directory
|
|
while building with a parallel make.
|
|
Use approved/supported Android method to check for NEON, use Linux/POSIX
|
|
1003.1 API to check /proc/self/auxv avoiding buffer allocation and other
|
|
library calls (ported from libpng15).
|
|
|
|
Version 1.6.1beta02 [February 19, 2013]
|
|
Use parentheses more consistently in "#if defined(MACRO)" tests.
|
|
Folded long lines.
|
|
Reenabled code to allow zero length PLTE chunks for MNG.
|
|
|
|
Version 1.6.1beta03 [February 19, 2013]
|
|
Fixed ALIGNED_MEMORY support.
|
|
Allow run-time ARM NEON checking to be disabled. A new configure option:
|
|
--enable-arm-neon=always will stop the run-time checks. New checks
|
|
within arm/arm_init.c will cause the code not to be compiled unless
|
|
__ARM_NEON__ is set. This should make it fail safe (if someone asks
|
|
for it on then the build will fail if it can't be done.)
