* 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.
1. Support empty struct as call arg.
2. Define _ATL_DECLSPEC_ALLOCATOR for older atlbase.h
3. Fix typo in SROA_Parameter_HLSL::preprocessArgUsedInCall for use AllocaBuilder when need RetBuilder.
1. Don't check hasMulticomponentUAVLoads for lib.
2. Skip mem2reg for unpromotable handle alloca for lib.
3. Support find resource attribute from function call.
4. Avoid unpack for dxil types.
5. Add resource attribute for fieldAnnotation.
* Fix ViewID state for flow control and consistent ViewID detection
1. Different ways of determining ViewID usage led to assert or crash.
Use DxilModule flag to guarantee consistency. But this required
splitting DxilEmitMetadata pass into two passes, one that finalizes
the module and computes flags run before ComputeViewIdState, and one
that simply writes the metadata.
2. storeOutput in flow control with values not dependent on that flow,
such as literals, would not pick up control flow dependence.
Fix by picking up control flow dependence on storeOutput instructions,
not just the value being written.
* Fix control depenence computation
There was a bug in the implementation of the control dependence algorithm.
We were incorrectly iterating over all descendents in the postdom tree where
the algorithm should only iterate over immediate children.
This change is to support preserve denorm operations. We do this by creating dxc options and propagate them all the way to dxil metadata so that drivers can see how it should handle floats.
Currently we support three modes: any(default), preserve, and ftz
Denorm option will be of per function flag. We store this information at function annotation metadata. This means that for DXIL 1.2 we have a new structure for function annotation. The change in structure is documented on DXIL.rst
Supporting a custom allocator for dxcompiler.
Adds recovery for exceptions and out-of-memory handling.
Add custom allocator support to linker.
Fix for release-only test failure.
Removes assertion about presence of command-line option registration
1. Save signatures for each entry.
2. Lower signatures and strip parameters for each entry.
3. Don't save function props for patch constant function.
4. Erase value from vectorEltsMap once it is used in SROA_Parameter_HLSL::replaceCastArgument and SROA_Parameter_HLSL::replaceCastParameter.
5. Remove unused member of DxilGenerationPass.
6. Fix typo when clear semantic for cloned return annotation.
2. Clone shader entry to be called by other functions.
3. Skip ComputeViewIdState for library profile.
4. Change HLFunctionProps to DxilFunctionProps for DxilModule to use.
5. Don't add .flat to flattened function name.
- Fixed potential null pointer access
- make existence of external directory optional
- add DxilContainerAssembler change missing from ViewID Validation changes
- fix in ShaderOpTest.h for other build tools.
1. Don't require entry function for flattenGlobal.
2. Don't check bForParam for flattenArgument.
3. Don't clone and remove return when replace return value with alloca.
1. Generate memcpy in EmitHLSLFlatConversionAggregateCopy if type is match.
2. If value is used as Src of memcpy, mark load instead of store.
3. Do not do replace on GEP and bitcast.
4. Delete inst instead of push into DeadInsts when safe.
This will prevent same inst added into DeadInsts more than once.
* Update PSV with ViewID data structures
* Update PSV with signature element data and gate PSV1 on SM 6.1
* Unwrap array on primitive when assigning semantic indexes
- fix semantic index assignment for matrix and primitives
- fix some tests
- disable two tests due to AssembleToContainer fail:
ValidationTest::SigOutOfRangeFail
ValidationTest::SimpleGs1Fail
1. Add ResourceToHandle pass to lower resource to handle.
2. Don't performPromotion in SROA_HLSL.
3. Add Option support for DynamicIndexingVectorToArray.
4. Fix bug in GetPassOption.
5. Replace GEP ptr, 0 with ptr in DynamicIndexingVectorToArray::ReplaceStaticIndexingOnVector.
6. Run mem2reg before DxilGenerationPass.
7.Legalize EvalOperations before change vector to array.
1. Try to propagate if the pointer is only write once by the memcpy.
2. Use correct size for memcpy created in AppendBuffer::Append.
3. Ignore unused Constant user of Matrix value.
4. Replace Constant with Inst on the Instruction version of Constant.
5. When match size of memcpy, go deeper if struct only has 1 element.
Doing this will leave memcpy be lowered at deeper level.
6. Do not replace when SimplePtrCopy, cannot decide replace is safe or not.
1. Keep major for matrix pointers.
2. Change matrix values to row major to match hlsl.
Only ColMatLoad, RowMatrixToColMatrix and col matrix value parameter for entry function are col major matrix value.
And should only used by ColMatStore and ColMatrixToRowMatrix.
This commit adds a new pass to hoist arrays from local to global scope
when the array only contains constant values. A local array will use
alloca and stores for initialization, but a global array uses a global
variable with a constant initializer.
The idea is that a global array with constant initializer will allow the
backend compilers to produce better code because it is much easier to see
that the array is fully constant.
This change modifies dxil constant folding to use the opcode class when
deciding if a dxil function can be constant folded. We now require a
DxilModule to be available when constant folding dxil functions.
To ensure that the dxil module is available we add a new pass that loads a
dxil module from metadata if it does not exist. We use the new pass in the
dxopt tests for constant folding.
* Lower resource to createHandle at clang code gen.
1. A HL createHandle will have 1 or 2 parameters.
For uav/srv/sampler, 1 parameter. 1 is the resource load from resource ptr.
For cbuffer, 2 parameter. 1 is the same. 2 is for dynamic indexing on array of cbuffers.
uav/srv/sampler don't have 2 is because all the use of them is on builtin methods. Resource on methods is scalar.
createHandle function will have metadata to save the resource information like class/kind/type/...
2. Added 2 more passes DxilLegalizeResourceUsePass DxilLegalizeStaticResourceUsePass to remove load/store on local/static resource.
Also make sure HL createHandle don't have phi operand.
3. For DxilGenerationPass, Dxil createHandle will be generated after GenerateDxilOperations.
And HLObjectOperationLowerHelper now get RK/RC from MetadataAsValue argument of HL createHandle.
* Save imm initializer when possible.
* Remove UpdateHLSLIncompleteArrayType which already done in SemaInit.
* Take care parent record in AddMissingCastOpsInInitList and HLSLExternalSource::GetNumBasicElements.
* Support nest init list in CaculateInitListArraySizeForHLSL.
