Frank Barchard	378bc91324	[libyuv] Multi-platform ScaleUVAddCols3 for ScaleUVBox at 3x ... Based on Philipp Hancke's AVX2 column kernel for ScaleUVBox at 3x (https://crrev.com/c/8427347). Add ScaleUVAddCols3 for exact 3x horizontal downscaling (dx == 0x30000 and boxheight <= 85) in ScaleUVBox, plus ScaleAddRow_AVX512BW and ScaleAddRow_WASMSIMD dispatch, and port 3x/box scaling kernels in scale_win.cc to 32/64-bit C++ intrinsics matching scale_gcc.cc: - ScaleUVAddCols3_C (portable C) - ScaleUVAddCols3_AVX2 and ScaleUVAddCols3_Any_AVX2 (scale_gcc.cc and scale_win.cc) - ScaleUVAddCols3_AVX512VBMI (scale_gcc.cc and scale_win.cc) - ScaleAddRow_SSE2, ScaleAddRow_AVX2, ScaleAddRow_AVX512BW, ScaleAddCols1_AVX512BW, ScaleAddCols2_AVX512BW, ScaleRowDown38_SSSE3, ScaleRowDown38_2_Box_SSSE3, and ScaleRowDown38_3_Box_SSSE3 in scale_win.cc for 32/64-bit Visual C and LIBYUV_ENABLE_ROWWIN - ScaleUVAddCols3_NEON (32-bit ARM and 64-bit AArch64) and ScaleUVAddCols3_Any_NEON - ScaleUVAddCols3_SME (ARMv9 Streaming SVE with whilelt predicate tail) - ScaleUVAddCols3_RVV (RISC-V Vector vlseg3e32.v inline asm) - ScaleUVAddCols3_LSX and ScaleUVAddCols3_Any_LSX (LoongArch LSX) - ScaleAddRow_WASMSIMD, ScaleAddRow_Any_WASMSIMD, ScaleUVAddCols3_WASMSIMD, and ScaleUVAddCols3_Any_WASMSIMD - ScaleUVAddCols3_HVX (Hexagon HVX vrdelta + vmpy_VuhRuh) Co-authored-by: Philipp Hancke <philipp.hancke@googlemail.com> Bug: libyuv:564129034 R=rrwinterton@gmail.com Change-Id: Ib9e14f3efcb097842c3d0e9fc9b473b6e2f81871 Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/8596436 Reviewed-by: richard winterton <rrwinterton@gmail.com>	2026-10-19 15:56:38 -07:00
Frank Barchard	2404f9730e	[libyuv] Rewrite LoongArch LSX/LASX kernels in compact inline asm ... Reduce loop unrolling across LoongArch LSX (128-bit) and LASX (256-bit) compare, row, rotate, and scale kernels to match SSE2/SSSE3 and AVX2 (1-2 vectors per iteration), rewrite intrinsics/macro implementations into GCC/Clang inline assembly, update all _Any wrapper masks and IS_ALIGNED dispatch checks, and port all remaining LSX Convert (+19) and Rotate (+2) kernels to LASX for full parity: ISA | Compare | Convert | Rotate | Scale -----------------|---------|---------|---------|-------- MIPS/Loong (Any) | 1 | 68 | 4 | 20 LSX | 1 | 68 | 4 | 20 LASX | 1 | 68 | 4 | 0 Removes 1,935 macro/helper lines from loongson_intrinsics.h (-99.3%) and reduces total LoongArch compiled .text size by 9,799 bytes (-25.1% overall, -37.4% row_lsx.cc, -52.3% scale_lsx.cc, -31.2% rotate_lsx.cc, -4.9% row_lasx.cc while adding +25 LASX functions): File | Before | After | Change -------------------|----------|----------|-------- scale_lsx.cc.o | 6,055 B | 2,888 B | -52.3% row_lsx.cc.o | 17,252 B | 10,792 B | -37.4% rotate_lsx.cc.o | 1,488 B | 1,024 B | -31.2% row_lasx.cc.o | 13,740 B | 13,072 B | -4.9% rotate_lasx.cc.o | 544 B | 1,504 B | +176.5% TOTAL .text | 39,079 B | 29,280 B | -25.1% R=wtc@google.com, yuanhecai@loongson.cn Test: qemu-loongarch64 -cpu la464 libyuv_unittest (LASX and LIBYUV_DISABLE_LASX=1) Change-Id: I11c1143ad2aad0399f10b2c3fc9bc4c02c740c59 Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/8564659 Reviewed-by: richard winterton <rrwinterton@gmail.com>	2026-10-16 17:25:23 -07:00
