* zlib: Use relative paths in pkg-config metadata fileJeffery To2019-05-171-0/+14
| | | | | | | | | | | | | | The buildroot pkg-config (in staging_dir/host/bin) overrides the prefix and exec_prefix variables in *.pc files, to supply the correct (buildroot) paths for callers. If other variables are not defined relative to prefix and exec_prefix, then the returned values will be incorrect. The default zlib.pc file generated by cmake contains absolute paths. This patches the file to use relative paths (relative to ${prefix} and ${exec_prefix}). Signed-off-by: Jeffery To <jeffery.to@gmail.com>
* package/libs/zlib: Add ARM and NEON optimizationsDaniel Engberg2018-01-023-0/+2764
This adds two optimizations for ARM: NEON optimized Adler(-)32 checksum algorithm (ARMv7 and newer NEON CPUs) ARM(v7+) specific optimization for inflate I've also connected inflate optimization to the build using the following source as template. https://github.com/mirror/chromium/commit/0397489124ce7e6aced020f8b85f5034c7d5f49b#diff-a62ad2db6c83dbc205d34bb9a8884f16 Additional info: https://codereview.chromium.org/2676493007/ https://codereview.chromium.org/2722063002/ Sources: https://github.com/madler/zlib/pull/251 (only the first commit) https://github.com/madler/zlib/pull/256 Signed-off-by: Daniel Engberg <daniel.engberg.lists@pyret.net>
