      dav1dplay: Add -lm for llround() support · 58cb4cf0
      Emmanuel Gil Peyrot authored
      Neither --buildtype=plain nor --buildtype=debug set -ffast-math, so
      llround() is kept as a function call and isn’t optimised out into
      cvttsd2siq (on amd64), thus requiring the math lib to be linked.
      
      Note that even with -ffast-math, it isn’t guaranteed that a call to
      llround() will always be omitted (I have reproduced this on PowerPC), so
      this fix is correct even if we ever decide to enable -ffast-math in
      other build types.

      arm64: looprestoration: Rewrite the wiener functions · 2e73051c
      Martin Storsjö authored
      Make them operate in a more cache friendly manner, interleaving
      horizontal and vertical filtering (reducing the amount of stack
      used from 51 KB to 4 KB), similar to what was done for x86 in
      78d27b7d.
      
      This also adds separate 5tap versions of the filters and unrolls
      the vertical filter a bit more (which maybe could have been done
      without doing the rewrite).
      
      This does, however, increase the compiled code size by around
      3.5 KB.

      build: Fix ninja warning message on Windows · 69268d3a
      Henrik Gramner authored
      We currently run 'git describe --match' to obtain the current version,
      but meson doesn't properly quote/escape the pattern string on Windows.
      
      As a result, "fatal: Not a valid object name .ninja_log" is printed
      when compiling on Windows systems. Compilation still works, but the
      warning is annoying and misleading.
      
      Currently we don't actually need the pattern matching functionality
      (which is why things still work), so simply remove it as a workaround.

      arm64: warped motion: Various optimizations · a3b8157e
      Kyle Siefring authored
      - Reorder loads of filters to benifit in order cores.
      - Use full 128-bit vectors to transpose 8x8 bytes. zip1 is called in the
         first stage which will hurt performance on some older big cores.
      - Rework horz stage for 8 bit mode:
          * Use smull instead of mul
          * Replace existing narrow and long instructions
          * Replace mov after calling with right shift
