	* Shader cache index integrated into RendererBase; Added test for cache eviction policy (which currently does not pass) * Restructured main if block in getEntryPointCodeFromShaderCache; Post-rebase cleanup * undo local testing only change * Fixed issues causing shader cache tests to fail * Edited gfx.slang to reflect structural changes to IDevice::Desc and to include ShaderCacheDesc; Modified how the cache is reading in the file from disk; Added a check to the cache eviction policy test that checks for correct order of entries in the cache as well as eight total expected output files for D3D12 and Vulkan * Removed line in gfx-unit-test.cpp for local testing * Edited .gitignore to ignore all shaders automatically generated by the shader cache tests and removed the test shaders that were previously added; Review changes, most notably with an overhaul of how the cache eviction policy test handles checking order of entries * Ran premake; Removed local testing specific line (again) * Removed expected comparison files from earlier commit; Ran premake * Edited premake5.lua to also ignore the auto-generated shader files from specific shader cache tests * Fixed weird indent in premake5.lua
2022-10-12	Shader caching (#2432)	lucy96chen
	* Changed all getEntryPointCode calls to use RendererBase::getEntryPointCodeFromShaderCache * Hashing hooked up, tests pass but need to add more to fully test functionality * checkpoint * Checkpoint: File system creation seems functional, saving is broken * checkpoint: Fixed filename generation from MD5 hash, shader blob might be going missing ahead of pipeline state creation * Fixed a lot of bugs related to hash code generation, shader cache is likely working but needs further testing * Added workaround for module loading by re-creating the test device, shader cache test functional * Vulkan shader caching bug fixed, checkpoint commit before more refinement * pre-ToT merge checkpoint * checkpoint commit, improving cache keys * Significantly expanded items included in the dependency hash for Module; Added dependency hash functions to SpecializedComponentType and RenamedEntryPointComponentType * Temporarily disable shader cache test * Mid cleanup changes, solution successfully builds * Added several helper update functions to slang-md5 to help simplify usage; Added a function under ISession to compute a hash for all linkage-related items; Function renames and cleaned up some comments * Ran premake.bat; Renamed getASTBasedHashCode to computeASTBasedHash * Added slang unit tests for Checksum and MD5; Extended gfx shader cache test to test with multiple shader files and one shader file with multiple entry points * Solution builds and shader cache tests pass, but at least a couple other tests now failing * ran premake.bat * More cleanup changes * Added shaderCachePath field to IDevice desc in gfx.slang, gfx-smoke.slang should be functional * ran premake * cleanup changes; Adding test printf to getEntryPointCodeFromShaderCache to see if output can be seen in CI * Removed debugging printfs; Added handling for getEntryPointCode() failing * Cleanup changes; Jonathan's fixes to SerialWriter to zero initialize otherwise uninitialized memory; Change to SwizzleExpr creation to zero initialize elementCount * Changed enable_if_t to enable_if * Fixed enable_if * Added test for import vs include and changes to included and imported files; Fixed build errors in CUDA; Renamed shader cache statistics fields * cleanup changes * Readd removed file * Restructured computeDependencyBasedHash calls, added computeDependencyBasedHashImpl to all classes dervied from ComponentType * Applied same restructuring to the AST hash functions * Cleanup changes; Moved HashBuilder out to slang-digest.h and added some helper functions to streamline the process of adding items to a hash * Cleanup; Fixed incorrect expected results for shader import and include test
