libhtscodecs2-1.5.0-bp156.1.4 RPM for ppc64le

From OpenSuSE Leap 15.6 for ppc64le

htscodecs provides an API to access CRAM codecs used for "EXTERNAL" block types.
These consist of two variants of the rANS codec (8-bit and 16-bit renormalisation,
with run-length encoding and bit-packing also supported in the latter),
a dynamic arithmetic coder, and custom codecs for name/ID compression
and quality score compression derived from fqzcomp.

Changelog

* Thu May 04 2023 Andrea Manzini <andrea.manzini@suse.com>
  - Update to 1.5.0:
    * Significant speed ups to the fqzcomp codec via code restructuring
      and use of memory prefetch instructions. Encode is 30-40% faster
      and decode 5-8% faster.
    * Remove unused ax_with_libdeflate.m4 file from build system
  - removed patch fix_ix86_build.patch already merged in upstream
  - Update to 1.4.0:
    * This is almost entirely minor bug fixing with a few small updates.
    * Optimise compression / speed of the name tokeniser
    * Improvements for Intel -m32 builds, including better AVX2 validation
    * Detect Neon capability at runtime via operating system APIs.
    * Update hts_pack to operate in line with CRAMcodecs spec, where the number of symbols > 16.
    * Fixed too-stringent buffer overflow checking in O1 rans decoder.
* Thu Sep 08 2022 Stefan Brüns <stefan.bruens@rwth-aachen.de>
  - Update to 1.3.0:
    * The primary change in this release is a new SIMD enabled
      rANS codec.
      There is a 32-way unrolled rANS implementation. This is accessed
      using the existing rans 4x16 API with the RANS_ORDER_X32 bit set.
    * Improved memory allocation via a new htscodecs_tls_alloc function.
    * Some external functions have been renamed, with the old ones
      still existing in a deprecated fashion.
    * Improved test framework with an "entropy" tool that iterates
      over all entropy encoders.
    * Reworked fuzzing infrastructure.
    * Small speed improvements to various rANS encoders and decoders.
    * Substantial memory reduction to the name tokeniser (tok3).
    * Fixed undefined behaviour in our use of _builtin_clz().
    * Fixed a few redundant #includes.
    * Work around strict aliasing bugs, uncovered with gcc -O2.
    * Fixed an issue with encoding data blocks close to 2GB in size.
    * Fix encode error with large blocks using RANS_ORDER_STRIPE.
  - Add fix_ix86_build.patch
* Wed Apr 20 2022 Ferdinand Thiessen <rpm@fthiessen.de>
  - Created initial package for libhts
