	* Remove old code paths from render-test Historically, the `render-test` tool was using three different code paths: * One based on `gfx` and manual (non-reflection-based) parameter setting, used for OpenGL, D3D11, D3D12, and Vulkan * One for CPU that used reflection-based parameter setting but shared no code with the first * One for CUDA that used reflection-based parameter setting and shared some, but not all, code with the CPU path Recently we've updated `render-test` to include a fourth option: * Using `gfx` and the "shader object" system it exposes for a unified reflection-based parameter-setting system taht works across OpenGL, D3D11, D3D12, Vulkan, CUDA, and CPU This change removes the first three options and leaves only the single unified path. A sa result, a bunch of code in `render-test` is no longer needed, and the codebase no longer relies on things like the `IDescriptorSet`-related APIs in `gfx`. Several existing tests had to be disabled to make this change possible. Those tests will need to be audited and either re-enabled once we fix issues in the shader object system, or permanently removed if they don't test stuff we intend to support in the long run (e.g., global-scope type parameters, which aren't a clear necessity). * fixup: CUDA detection logic

2020-05-26	Improvements around hashing (#1355)	jsmall-nvidia
	* Fields from upper to lower case in slang-ast-decl.h * Lower camel field names in slang-ast-stmt.h * Fix fields in slang-ast-expr.h * slang-ast-type.h make fields lowerCamel. * slang-ast-base.h members functions lowerCamel. * Method names in slang-ast-type.h to lowerCamel. * GetCanonicalType -> getCanonicalType * Substitute -> substitute * Equals -> equals ToString -> toString * ParentDecl -> parentDecl Members -> members * * Make hash code types explicit * Use HashCode as return type of GetHashCode * Added conversion from double to int64_t * Split Stable from other hash functions * toHash32/64 to convert a HashCode to the other styles. GetHashCode32/64 -> getHashCode32/64 GetStableHashCode32/64 -> getStableHashCode32/64 * Other Get/Stable/HashCode32/64 fixes * GetHashCode -> getHashCode * Equals -> equals * CreateCanonicalType -> createCanonicalType * Catches of polymorphic types should be through references otherwise slicing can occur. * Fixes for newer verison of gcc. Fix hashing problem on gcc for Dictionary. * Another fix for GetHashPos * Fix signed issue around GetHashPos
2020-01-29	Feature/test for double behavior (#1186)	jsmall-nvidia
	* Split out binding writing. * Pass in the entry type. * Take into account output type with -output-using-type Added GPULikeBindRoot Added dxbc-double-problem test. * Add the dxbc-double-problem test.
2020-01-17	Slang -> CUDA kernel runs correctly in test infrastructure (#1167)	jsmall-nvidia
	* First pass at BindLocation. * Added BindSet::init - for initializing with two input constant buffers. Needs better name, and perhaps should be another class. * Fix handling of constant buffer stripping. Improved initialization. * Trying to generalize BindLocation a little more. Split out CPULikeBindRoot. * More work to make BindLocation et al work with non uniform bindings. * Added parsing to a location. * WIP: Trying to get CPU working with BindLocation. * Describe problem of knowing the type of the reference point in the binding table. * More ideas on getBindings fix. * Remove BindSet as member of BindLocation. * Added BindLocation::Invalid * Made BindLocation able to be key in hash * Use BindLocation for bindings on BindingSet. * Added cuda and nvrtc categories to test infrastructure. Disabled CUDA synthetic tests by default. Fixed such that all tests now produce something in BindLocation style. * Use m_userIndex instead of m_userData on Resource. Move the binding setup out of cpu-compute-util (as no longer CPU specific) * Removed CPUBinding - used BindLocation/BindSet instead. Fixed some bugs around indexOf around uniform indirection. * Renamed BindSet::Resource -> BindSet::Value. * Document BindLocation. * Fixes for Clang/GCC Improve invariant requirement handling when constructing from BindPoints. * WIP: First attempt to run CUDA kernel. * Fix some issues around doing CUDA kernel launch. * Fix issues around use of cudaMemCpy . * Better cuda runtime error checking mechanism. * Fixed bug in passing parameters to cuda kernel launch. Simplified initialisation of context. * WIP: Fix CUDA runtime issues. * Add explicit CUDA synchronize so failures don't appear on implicit ones. * Fix problem emitting non shared variable on CUDA. * Fix some typos in CUDA layout. Use just a pointer for now for CUDA StucturedBuffer. * Arg order for CUDA launch was wrong. * First compute kernel runs on CUDA.
