This is one cycle faster in total, and three instructions fewer.
Before:
vp9_loop_filter_mix2_v_44_16_neon: 123.2
After:
vp9_loop_filter_mix2_v_44_16_neon: 122.2
This is cherrypicked from libav commit
3bf9c48320.

// The main loop filter macro is templated and can produce filters for
|
|
// vectors of 8 or 16 bytes. The register mapping throughout the filter
|
|
// is close to identical to the arm version (please try to maintain this,
|
|
// if either is changed!). When the arm version uses e.g. d20 for the
|
|
// input variable p3, the aarch64 version uses v20.8b or v20.16b, depending
|
|
// on vector length.
|
|
//
|
|
// The number of elements in the vector is passed in via the macro parameter
|
|
// \sz, which is either .8b or .16b. For simple instructions that doesn't
|
|
// lengthen or narrow things, this can easily be templated like this:
|
|
// uabd v4\sz, v20\sz, v21\sz
|
|
//
|
|
// For instructions that lengthen or narrow content, the arm version would
|
|
// have used q registers. For these instructions, we have macros that expand
|
|
// into either a single e.g. uaddl instruction, or into a uaddl + uaddl2
|
|
// pair, depending on the \sz parameter. Wherever the arm version would have
|
|
// used a q register, these macros instead take two v registers, i.e. q3
|
|
// is mapped to v6+v7. For the case with 8 byte input vectors, such a
|
|
// lengthening operation is only stored in v6.8h (what was in q3 in the arm
|
|
// case), while the 16 byte input vectors will use v6.8h + v7.8h.
|
|
// Such a macro invocation would look like this:
|
|
// uaddl_sz v8.8h, v9.8h, v17, v18, \sz
|
|
//
|
|
// That is, in the 8 byte input vector case, the second register in these
|
|
// register pairs will be unused.
|
|
// Unfortunately, this makes the code quite hard to read. For readability,
|
|
// see the arm version instead.
