The fxc compiler evaluates both operands before performing the
token-pasting operation. But the default Clang way is to follow
C standard, which token-pastes operands as-is, without any
pre-expanding.
This commit adds support for the fxc behavior via the command
line option: -flegacy-macro-expansion.
Fixes https://github.com/Microsoft/DirectXShaderCompiler/issues/1005
2. Not SROA on resource.
3. avoid unpack for resource.
4. Use value type for createHandleForLib.
5. Move all scalar global resource load to the beginning of function.
This will stop other pass do optimizations on the loads of scalar global resource.
6. Not remove local resource for lib.
- Keep track of patch constant functions for later identification
- functions that require input/output signature processing identified
with IsEntryThatUsesSignatures
- update lib_rt.hlsl intrinsics and naming
Two new Vulkan specific intrinsic resource types, SubpassInput and
SubpassInputMS, are introduced to provide a way to use subpass inputs
in Vulkan. Their signatures:
template<typename T>
class SubpassInput {
T SubpassLoad();
};
template<typename T>
class SubpassInputMS {
T SubpassLoad(int sample);
};
T can be a scalar or vector type.
If compiled without ENABLE_SPIRV_CODEGEN, the compiler will report
unknown type name for SubpassInput(MS). If compiled with SPIR-V
CodeGen and trying to use SubpassInput(MS) in DXIL CodeGen, the
compiler will report an error saying the type is Vulkan-specific.
A new Vulkan-specific attribute, vk::input_attachment_index is
introduced to provide a way to set the input attachment index for
SubpassInput(MS) objects.
- 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.
