      x86: Rewrite SGR AVX2 asm · fe2bb774
      Henrik Gramner authored
      The previous implementation did multiple passes in the horizontal
      and vertical directions, with the intermediate values being stored
      in buffers on the stack. This caused bad cache thrashing.
      
      By interleaving the all the different passes in combination with a
      ring buffer for storing only a few rows at a time the performance
      is improved by a significant amount.
      
      Also slightly speed up neighbor calculations by packing the a and b
      values into a single 32-bit unsigned integer which allows calculations
      on both values simultaneously.

      Add minor SGR optimizations · c290c02e
      Henrik Gramner authored
      Split the 5x5, 3x3, and mix cases into separate functions.
      
      Shrink some tables.
      
      Move some scalar calculations out of the DSP function.
      
      Make Wiener and SGR share the same function prototype to
      eliminate a branch in lr_stripe().

      x86inc: Add stack probing on Windows · c36b191a
      Henrik Gramner authored
      Large stack allocations on Windows need to use stack probing in order
      to guarantee that all stack memory is committed before accessing it.
      This is done by ensuring that the guard page(s) at the end of the
      currently committed pages are touched prior to any pages beyond that.

      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.
