Jan Wassenberg	8c0a8834c1	Major compression update, arbitrary-len unpack + new Dot ... Compression: * Implement {any packed} x {bf16, f32} 'Load2' and DecompressAndZeroPad * New compression test for all packed formats, add to GEMMA_TEST_FILES, remove from sfp/nuq_test * Decompress->DecompressAndZeroPad, use PackedSpan for args with bounds checking * NUQ: support arbitrary-length enc/dec * New compression/shared, remove sfp.h and nuq.h * Move Store2 into Traits and provide Compress2 wrapper * Remove unused Decompress()-with-pool overload * Simplify CompressedArrayLen, rename to CompressedArrayElements * Remove unused DistortionStats b_l1_ Misc: * Add compensated and Kahan dot, support any length * Use same Dot function everywhere * Move exact arithmetic functions into fp_arith * use FloatPtr and MatPtr typedefs in tests; less stack usage * Rename args to packed/raw * Remove Traits::Name, instead TypeName<T>() * Move kMaxSFP and kClusters/kGroupSize into Sfp/NuqStream PiperOrigin-RevId: 672868468	2024-09-10 02:22:19 -07:00
Jan Wassenberg	c29e9752c7	Refactor/cleanup, remove even_odd ... * New compression/shared.h, remove sfp.h * Remove unused DistortionStats b_l1_ * Move exact arithmetic functions into fp_arith * Remove even_odd optimization for MatVec (mostly unused) * use BF16 typedef more widely * Add kMaxSFP constant PiperOrigin-RevId: 670996386	2024-09-04 09:25:13 -07:00
