- Cleaning up execution test
- Generating xml test file from the script and hctdb
- Fixing hctdb categories for unsigned int
- Adding more execution tests (Fadd, FSub, FMul, FDiv, Add, Sub, SDiv)
Added a new command line option -fvk-ignore-unused-resources
to avoid emitting SPIR-V code for resources defined but not statically
referenced by the call tree of the entry point in question.
Uses the legalization pass recipe from SPIRV-Tools.
Also change -fcgl to disable both legalization and optimization.
Validation on some tests are turned off because of new image
instruction checking in SPIRV-Tools. Enabling them is a TODO.
-bump up dll version for fixed version
-show dxcompiler and dxil version number for dxc help message
-emit warnings for dxcompiler validator that container will not be signed
This change removes new Load variations (LoadHalf, LoadFloat, etc) for RWByteAddressBuffer/ByteAddressBuffer methods and add templated Load intrinsics. This templated Load only works on scalar or vector types, and its variations (Load2, Load3, Load4, etc) do not work with templates and work as it did before (only storing uints). For Store operation, you can store any scalar or vector types of up to 16 bytes, while prior to 2018 Store only supported storing uint scalar.
This change is to add fixed width scalar types in HLSL 2018.
These types are: int16_t, uint16_t, int32_t, uint32_t, float16_t, float32_t, and float64_t.
Prior HLSL versions do not support these fixed width types.
This change also renames /no-min-precision command line option to /enable-16bit-types. int16_t and uint16_t are only allowed with this mode.
This change is to introduce native precision types for shader model 6.2. With native half (float16) types, we will introduce native int16/uint16 types with same command line option. This means that one option will disable all min precision types. For now, int16/uint16 types will be exposed on HLSL level as int16_t and uint16_t.
This change also includes some constant buffer fixes for 16 bit types, as well as int64 types.
This change is an extension of float16 support. We are adding LoadHalf, LoadFloat, and LoadDouble method to byte address buffer so that users can access data from byte address buffer by these types. Also starting shader model 6.2, we are mapping byte address buffer and structure buffer load/store operations to RawBufferLoad/Store to differentiate raw buffer load from typed buffer load. Unlike BufferLoad for typed buffers, RawBufferLoad for min precision types will not have its min precision values as its return types, but their actual scalar size in buffer (i.e rawBufferLoad.i32 for min16int and rawBufferLoad.f32 for min16float). RawBufferLoad/Store contains additional parameters, where mask was required for correct status behavior for CheckAccessFullyMapped, and alignment is for relative alignment for future potential benefit for backend.
* byte offset, not element offset => multiply by sizeof(dword)
set uav to r/w
Re-emit meta-data becomes delete then emit
* update test
* re-compute view id state
This change is to update correct target data layout for DXIL. Now that we have a scalar type of size less than dwords, we need to correctly print string data layout to determine non-packed structure layout.
This change also fixes alignments issues with ConstantBuffer as it was having different CG path from cbuffer.
Added the following four command line options to shift register
number for Vulkan:
* -fvk-b-shift
* -fvk-t-shift
* -fvk-s-shift
* -fvk-u-shift
These options are used to avoid assigning the same binding
number to more than one resources.
Structure buffer alignment change for float16. Starting in shader model 6.2, the structure will match that of #pragma pack(8) alignment in C++
Removing padding for structure buffer. We will not have any padding in HLSL structure since load/store operation already handles offset as if padding exist in #pragma pack(8) mode in C++
Disable legacy alignment for non precision mode as it was only needed for min precision
* Adds support for pause/resume in pipeline.
* Adds 0.0 as the validator version to indicate no validation should occur.
* Moves module parsing from dxcompiler down to HLSL library.
* Adds support for optimizer to process a DXIL part.
* Adds a form with designer support for the interactive optimizer.
See the comment in DxilDebugInstrumentation.cpp for a summary of how this-all works. Basically: instrument all instructions to output "trace" info to a UAV so that a debugger can reconstruct the execution of the shader and offer a debugger-like experience.
* Add SV_Position index parameter, various minor tweaks to UAV setup
* Convert to raw buffer
* fix up unit tests, add a few names to variables
* CR feedback: check for pre-existing type; typo
This change is to enforce the new constraint on signature packing: pack signature elements by data width. Before we introduce fp16 type, every element was assumed to reserve 32 bits. Since we are introducing a new 16 bit data type, we need a new way to enforce signature rules.
After discussions we decided that it would be nice to pack elements based on data width. However, we are still enforcing the rule that each row contains up to 4 elements, regardless of the size. This way, depending on the hardware support drivers can optimize packing signatures, while on DXIL level we maintain the assumption that there are 4 elements per row. We are also still constraining on the total number of rows to be 32 for now. This can be changed in the future if people find this limit to be an issue.
