Normally no changes to the programs are done; they decode +// into exactly same program as what was encoded. Optionally, debug information +// can be removed too. +// +// SPIR-V is a very verbose format, several times larger than same programs expressed in other +// shader formats (e.g. DX11 bytecode, GLSL, DX9 bytecode etc.). The SSA-form with ever increasing +// IDs is not very appreciated by regular data compressors either. SMOL-V does several things +// to improve this: +// - Many words, especially ones that most often have small values, are encoded using +// "varint" scheme (1-5 bytes per word, with just one byte for values in 0..127 range). +// See https://developers.google.com/protocol-buffers/docs/encoding +// - Some IDs used in the program are delta-encoded, relative to previously seen IDs (e.g. Result +// IDs). Often instructions reference things that were computed just before, so this results in +// small deltas. These values are also encoded using "varint" scheme. +// - Reordering instruction opcodes so that the most common ones are the smallest values, for smaller +// varint encoding. +// - Encoding several instructions in a more compact form, e.g. the "typical <=4 component swizzle" +// shape of a VectorShuffle instruction, or sequences of MemberDecorate instructions. +// +// A somewhat similar utility is spirv-remap from glslang, see +// https://github.com/KhronosGroup/glslang/blob/master/README-spirv-remap.txt +// +// +// ### USAGE: +// +// Add source/smolv.h and source/smolv.cpp to your C++ project build. +// Currently it might require C++11 or somesuch; I only tested with Visual Studio 2017/2019, Mac Xcode 11 and Gcc 5.4. +// +// smolv::Encode and smolv::Decode is the basic functionality. +// +// Other functions are for development/statistics purposes, to figure out frequencies and +// distributions of the instructions. +// +// There's a test + compression benchmarking suite in testing/testmain.cpp; using that needs adding +// other files under testing/external to the build too (3rd party code: glslang remapper, Zstd, LZ4). +// +// +// ### LIMITATIONS / TODO: +// +// - SPIR-V where the words got stored in big-endian layout is not supported yet. +// - The whole thing might not work on Big-Endian CPUs. It might, but I'm not 100% sure. +// - Not much prevention is done against malformed/corrupted inputs, TODO. +// - Out of memory cases are not handled. The code will either throw exception +// or crash, depending on your compilation flags. + +#pragma once + +#include +#include +#include + +namespace smolv +{ + typedef std::vector ByteArray; + + enum EncodeFlags + { + kEncodeFlagNone = 0, + kEncodeFlagStripDebugInfo = (1<<0), // Strip all optional SPIR-V instructions (debug names etc.) + }; + enum DecodeFlags + { + kDecodeFlagNone = 0, + kDecodeFlagUse20160831AsZeroVersion = (1 << 0), // For "version zero" of SMOL-V encoding, use 2016 08 31 code path (this is what happens to be used by Unity 2017-2020) + }; + + // Preserve *some* OpName debug names. + // Return true to preserve, false to strip. + // This is really only used to implement a workaround for problems with some Vulkan drivers. + typedef bool(*StripOpNameFilterFunc)(const char* name); + + // ------------------------------------------------------------------- + // Encoding / Decoding + + // Encode SPIR-V into SMOL-V. + // + // Resulting data is appended to outSmolv array (the array is not cleared). + // + // flags is bitset of EncodeFlags values. + // + // Returns false on malformed SPIR-V input; if that happens the output array might get + // partial/broken SMOL-V program. + bool Encode(const void* spirvData, size_t spirvSize, ByteArray& outSmolv, uint32_t flags = kEncodeFlagNone, StripOpNameFilterFunc stripFilter = 0); + + + // Decode SMOL-V into SPIR-V. + // + // Resulting data is written into the passed buffer.
