Frank Barchard c28ebdd357 [libyuv] Rewrite LoongArch LSX/LASX kernels in compact inline asm ... Reduce loop unrolling across LoongArch LSX (128-bit) and LASX (256-bit) 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) | 0 | 68 | 4 | 20 LSX | 0 | 68 | 4 | 20 LASX | 0 | 68 | 4 | 0 Removes 1,935 macro/helper lines from loongson_intrinsics.h (-99.3%) and reduces total LoongArch compiled .text size by 9,246 bytes (-24.3% overall, -36.9% row_lsx.cc, -52.7% scale_lsx.cc, -31.2% rotate_lsx.cc, -2.8% row_lasx.cc while adding +25 LASX functions): File | Before | After | Change -------------------|----------|----------|-------- scale_lsx.cc.o | 6,102 B | 2,888 B | -52.7% row_lsx.cc.o | 16,704 B | 10,544 B | -36.9% rotate_lsx.cc.o | 1,488 B | 1,024 B | -31.2% row_lasx.cc.o | 13,168 B | 12,800 B | -2.8% rotate_lasx.cc.o | 544 B | 1,504 B | +176.5% TOTAL .text | 38,006 B | 28,760 B | -24.3% R=wtc@google.com, yuanhecai@loongson.cn Test: qemu-loongarch64 -cpu la464 libyuv_unittest (LASX and LIBYUV_DISABLE_LASX=1) Change-Id: I11c1143ad2aad0399f10b2c3fc9bc4c02c740c59		2026-10-12 18:39:22 -07:00
