- update to 2.2.3:
* This time we have two code fixes for potentially unsafe
access, although we have not had any bug-reports about these.
* It also contains several optimizations. Especially of note,
inflate has been optimized on various instruction sets and
also the generic C code has seen improvements, and we have
improvements for arches where unaligned accesses are not
possible (lacking instructions to handle unaligned access)
and also improvements on big endian.
* x86-64 AVX2: Inflate ~17.8% faster, Deflate unchanged. -4.6KB
library size.
* Aarch64: Inflate ~2.3% faster, Deflate unchanged. - 5.5KB
library size.
* We also took some time to do a comprehensive cleanup of the
now misleading UNALIGNED_OK option and of all the "unaligned"
functions. We have noticed that some distros have been
disabling these, fearing they are using potentially unsafe
unaligned pointers, but we already fixed that in 2.1.0-beta1.
Since then, these "unaligned" settings/functions have been
referring to using unaligned accesses in safe ways, like
utilizing unaligned intrinsics or memcpy to fix alignment for
example and selecting what safe method is optimal to the
arch. So disabling that instead disabled several safe
optimizations.
* Because this was obviously misleading certain distros into
disabling these optimizations, we have cleaned it up, removed
a lot of unnecessary preprocessor checks, and made detection
of optimal methods happen during compile instead of
configure. As a bonus, this cleaned up a lot of code and also
let us not compile in many extra variants of
compare256/longest_match, saving about 8-10KB of library
size.
* PS: s390x is currently potentially unsafe, CI reports a
failure on the MSAN test, this is pending investigation by
IBM. See #1845.
* Any Zlib-ng version on s390x built with VX-extensions enabled
compiled using a buggy Clang version will be unsafe.
