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.

The second halves of the +// registers are rows 3 and 4. +// This only is designed to work for 4 or 8 output lines. +.macro do_8tap_4v type, idx1, idx2 +function \type\()_8tap_4v_\idx1\idx2 + sub x2, x2, x3, lsl #1 + sub x2, x2, x3 + ld1 {v0.8h}, [x6] +.ifc \type,avg + mov x7, x0 +.endif + + ld1 {v1.s}[0], [x2], x3 + ld1 {v2.s}[0], [x2], x3 + ld1 {v3.s}[0], [x2], x3 + ld1 {v4.s}[0], [x2], x3 + ld1 {v5.s}[0], [x2], x3 + ld1 {v6.s}[0], [x2], x3 + trn1 v1.2s, v1.2s, v3.2s + ld1 {v7.s}[0], [x2], x3 + trn1 v2.2s, v2.2s, v4.2s + ld1 {v26.s}[0], [x2], x3 + uxtl v17.8h, v1.8b + trn1 v3.2s, v3.2s, v5.2s + ld1 {v27.s}[0], [x2], x3 + uxtl v18.8h, v2.8b + trn1 v4.2s, v4.2s, v6.2s + ld1 {v28.s}[0], [x2], x3 + uxtl v19.8h, v3.8b + trn1 v5.2s, v5.2s, v7.2s + ld1 {v29.s}[0], [x2], x3 + uxtl v20.8h, v4.8b + trn1 v6.2s, v6.2s, v26.2s + uxtl v21.8h, v5.8b + trn1 v7.2s, v7.2s, v27.2s + uxtl v22.8h, v6.8b + trn1 v26.2s, v26.2s, v28.2s + uxtl v23.8h, v7.8b + trn1 v27.2s, v27.2s, v29.2s + uxtl v24.8h, v26.8b + uxtl v25.8h, v27.8b + + convolve v1, v2, v17, v18, v19, v20, v21, v22, v23, v24, v25, \idx1, \idx2, v3, v4 + do_store4 v1, v2, v5, v6, \type + + subs x4, x4, #4 + b.eq 9f + + ld1 {v1.s}[0], [x2], x3 + ld1 {v2.s}[0], [x2], x3 + trn1 v28.2s, v28.2s, v1.2s + trn1 v29.2s, v29.2s, v2.2s + ld1 {v1.s}[1], [x2], x3 + uxtl v26.8h, v28.8b + ld1 {v2.s}[1], [x2], x3 + uxtl v27.8h, v29.8b + uxtl v28.8h, v1.8b + uxtl v29.8h, v2.8b + + convolve v1, v2, v21, v22, v23, v24, v25, v26, v27, v28, v29, \idx1, \idx2, v3, v4 + do_store4 v1, v2, v5, v6, \type + +9: + ret +endfunc +.endm + +do_8tap_4v put, 3, 4 +do_8tap_4v put, 4, 3 +do_8tap_4v avg, 3, 4 +do_8tap_4v avg, 4, 3 + + +.macro do_8tap_v_func type, filter, offset, size +function ff_vp9_\type\()_\filter\()\size\()_v_neon, export=1 + uxtw x4, w4 + movrel x5, X(ff_vp9_subpel_filters), 256*\offset + cmp w6, #8 + add x6, x5, w6, uxtw #4 + mov x5, #\size +.if \size >= 8 + b.ge \type\()_8tap_8v_34 + b \type\()_8tap_8v_43 +.else + b.ge \type\()_8tap_4v_34 + b \type\()_8tap_4v_43 +.endif +endfunc +.endm + +.macro do_8tap_v_filters size +do_8tap_v_func put, regular, 1, \size +do_8tap_v_func avg, regular, 1, \size +do_8tap_v_func put, sharp, 2, \size +do_8tap_v_func avg, sharp, 2, \size +do_8tap_v_func put, smooth, 0, \size +do_8tap_v_func avg, smooth, 0, \size +.endm + +do_8tap_v_filters 64 +do_8tap_v_filters 32 +do_8tap_v_filters 16 +do_8tap_v_filters 8 +do_8tap_v_filters 4 |
