1. MergeGepUse for cbuffer and temp gep created when flatten.
2. When flatten alloca, always keep order by size of type.
So we can make sure big alloca flattened first, then small alloca can easier remove memcpy.
3. For global variable which has zero init value, replace use of zero initializer if possible.
4. In ResourceToHandle::ReplaceResourceWithHandle only assert when has user.
5. MergeGepUse for input output in collectInputOutputAccessInfo.
Avoid inserting other insts before allocas in several passes.
- Improve code that creates allocas/non-allocas to keep allocas first
- Add helper functions to dxilutil
- Use name AllocaBuilder for CreateAlloca for clarity
Fix HoistConstantArray pass to recognize more complex load & store patterns.
Previously it was expecting no nesting and just a simple list of GetElementPtr's that fed loads or stores. Now it can accept a tree (DAG) of GetElementPtrs that feed leaf node loads or stores.
These patterns cannot be directly derived from HLSL, however they can occur due to previous optimizations that transform the array accesses (like a partial CSE or similar).
- Improve code that creates allocas/non-allocas to keep allocas first
- Add helper functions to dxilutil
- Use name AllocaBuilder for CreateAlloca for clarity
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
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.
* 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.
