3.7
f48cc27

The 3.7 release contains another round of performance optimizations, including significant improvements to the command line front-end (faster PNG loader) and the arm64 build of the codec (faster NEON implementation).

Change log

General:

  • Feature: The command line tool PNG loader has been switched to use the Wuffs library, which is significantly faster than the current implementation.
  • Feature: Support for non-invariant builds returns. Opt-in to slightly faster, but not bit-exact, builds by setting -DNO_INVARIANCE=ON for the CMake configuration. This improves performance by around 2%.
  • Optimization: Changed SIMD select() so that it matches the default NEON behavior (bitwise select), rather than the default x86-64 behavior (lane select on MSB). Specialization select_msb() added for the one case we want to select on a sign-bit, where NEON needs a different implementation. This provides a significant (>25%) performance uplift on NEON implementations.
