- Update to 1.6.0:
* Changes
+ Replaced the rANS codec SIMD gathers with simulated gathers
via scalar memory fetches. This helps AMD Zen4, but
importantly it also fixes a disastrous performance regression
caused by Intel's DownFall microcode fix.
+ There is an impact on pre-DownFall speeds, but we should
focus on patched CPUs as a priority.
+ A small speed up to the rans_F_to_s3 function used by
order-0 rans decode.
+ Small speed up to SIMD rans32x16 order-1 encoder by reducing
cache misses. Also sped up the rans4x8 order-1 encoder,
particularly on AMD Zen4.
+ Now supports building with "zig cc"
* Bug fixes
+ Improve robustness of name tokeniser when given non 7-bit
ASCII and on machines where "char" defaults to unsigned.
+ Also fixed a 1 byte buffer read-overrun in name tokeniser.
+ Fix name tokeniser encoder failure with some duplicated
streams.
+ Fixed rans_set_cpu to work multiple times, as well as
reinstating the ability to change decode and encode side
independently (accidentally lost in commit 958032c). No
effect on usage, but it improves the test coverage.
+ Added a round-trip fuzz tester to test the ability to
encode. The old fuzz testing was decode streams only.
+ Fixed bounds checking in rans_uncompress_O0_32x16_avx2,
fixing buffer read overruns.
+ Removed undefined behaviour in transpose_and_copy(),
fixing zig cc builds.
