2024-08-14Issue/legalize resource (#4769)kaizhangNV
* Fix the issue that NonUniformResourceIndex is ignored Fix the issue that after `specializeFunctionCalls`, `NonUniformResourceIndex` is ignored in the generated specialized function. The reason is that if the function has a non-uniform resource parameter, we will legalize it by replacing the resource parameter with a index, and indexing of the resource will be moved inside the specialized function. e.g. ``` void func(ResourceType resource) { ... } func(resource[NonUniformResourceIndex(0)]) ``` will be specialized into ``` void func(int index) { resource[index]; } func(0); ``` In this case, inside the function, we will loose the information about whether the resource is a non-uniform. So we add the handling for this corner case by adding insert a `NonUniformResourceIndex` into the specialized function: ``` void func(int index) { int nonUniformIdx = NonUniformResourceIndex(index); resource[nonUniformIdx]; } ``` * Fix the issue that arguments mismatch after specilization callsite specializeCall() call could cause arguments mismatch with the parameters of the specialized function. For example, if the function parameter contains a resource type ``` void func(ResourceType res) { ... } int index = ... func(resources[index]); ``` This will be specialized into ``` void func(int index) { resources[index] } int index = ... func(index); ``` However, if we have more than 1 call sites, and the other call site doesn't use `int` as the index, e.g. ``` uint index = ... func(resources[index]); ``` this call site will be specialized into ``` uint index = ... func(index); ``` this will be invalid, because the argument doesn't match the parameter. so we just add the data type of the new arguments into the function key such that For the uniformity info, we add a new attribute "IROp_NonUniformAttr", so we will form a IRAttributedType that encodes both uniformity and data type, and use it as the key of call info. So if there is call site using the different data type for the resource index, we will specialize a new function for this. * Handle the intCast and uintCast operation Since after intCast/uintCast of nonuniformIndex, it's still a nonuniformIndex. So we will handle this case as well. Also, add a new test to cover this.
2024-08-13GitHub action benchmark (#4804)venkataram-nv
Adds a new Github CI action for benchmarking the slangc compiler on the MDL shaders. For now, the results are only dumped to the output of the CI, which can be later viewed through raw logs. The next step is to use github-action-benchmark to push these results into a page which will show the benchmark results over time as commits are pushed.
2024-08-13FIx issue with specializing witness tables (#4839)Sai Praveen Bangaru
2024-08-13Do not add carrage return to shell scripts (#4811)Jay Kwak
This commit prevents GIT from adding carrage return characters to shell script files whose file extension is ".sh". Currently git automatically adds a carrage return characters to all lines in text files, which makes them Windows text file. This causes a trouble when a shell script is submitted and it is ran on WSL, because bash on WSL expects the script files in a unix text file format. Co-authored-by: Yong He <yonghe@outlook.com>

2024-08-12Warn when inout parameter is never written (#4777)venkataram-nv
Addresses #4698 as one approach to diagnose the potential problem. Emit warnings when a user marks a parameter as `inout` but never writes to it in the function. A new intrinsic function `unmodified(out T)` has been added to explicitly indicate that an `inout` variable will not be modified in the function. This is only one way to address the specific validation error in #4698. In general it seems that DXC does some more extensive checks on actual struct fields (as opposed to observing arbitrary struct writes), so that will be the next step.
2024-08-07Reduce dependency on std library (#4785)skallweitNV
2024-08-07More reflection API features. (#4740)Sai Praveen Bangaru
* More reflection API features. + Lookup methods and members (by string) on types + Fix issue with looking up non-static members through the scope operator '::' + `GenericReflection`: Cast a decl to generic to access unspecialized generic parameter names and constraints + `GenericReflection`: Use `getGenericContainer()` from function, variable or type to access the 'nearest' generic parent along with specialization info + `GenericReflection::getConcreteType` and `GenericReflection::getConcreteIntVal`: to get the concrete type of a param in the context of the reflection object + `GenericReflection::getOuterGenericContainer` to go up one level and get the outer generic declarations (if there are more than one enclosing generic scopes) + `DeclReflection::getParent`: go to parent declaration. + Change `VariableReflection` to be a `DeclRef` rather than a decl (allows us to return properly substituted types for methods, members, and more) * Fix Falcor issue

Some debug code was left in by accident which called DXC to disassemble the DXIL it produced.
2024-08-06Support an Upper-case variant of [NumThreads] and [Shader] (#4780)Jay Kwak
Closes #4746. This commit adds a support for "NumThreads" and "Shader" attribute keyword, which is in CamelCasing starting with an upper case letter. The attribute keywords in HLSL are case-insensitive. As an example, one of D3D documents says, "The attribute name "Shader" is case insensitive." https://microsoft.github.io/DirectX-Specs/d3d/WorkGraphs.html Slang, however, doesn't support the case-insensitivity. They should be all lower-case or CamelCasing starting with an upper case.
2024-08-05Initial support for precompiled DXIL in slang-modules (#4755)cheneym2
* Add embedded precompiled binary IR ops Add IR operations to embed precompiled DXIL or SPIR-V blobs into IR. Adds a BlobLit literal that is mostly identical to StringLit except for its inability to be displayed, e.g. in dumped IR. In the future, the blob might be dumped as hexadecimal, but for now it is summarized as "<binary blob>". * EmbeddedDXIL and SPIR-V options The options, '-embed-dxil' and '-embed-spirv' in slangc, will cause a target dxil or spirv to be compiled and stored in the translation unit IR when written to a slang-module. Subsequent changes actually implement the options. * Per-translation unit DXIL precompilation When -embed-dxil is specified, perform a precompilation to DXIL of each TU, linked only with stdlib. Embed the resulting DXIL for the TU in a IR op. Being part of IR, the precompiled DXIL can be serialized to disk in a slang-module. Upon loading slang-modules, the new IR op will be searched for and the precompiled DXIL blob is saved with the loaded Module. During linking, if all the Modules have precompiled blobs they will be sent to the downstream compile commands as libraries instead of source, skipping the downstream compilation, using DXC only for linking. Fixes Issue #4580 * Remove placeholder embedded SPIRV support Code was added only to sketch out how other precompiled bins will be supported. * Remove the rest of the SPIRV placeholder support * Fix warnings, test error on non-windows * Remove lib_6_6 hack, add dxil_lib capability * Allocate blob value from irmodule memarena * Add null check after memarena allocation * Restore the request->e2erequest code path for generatewholeprogram * Update capability handling, move EmbedDXIL enum to end to preserve abi * Remove lib_6_6 hack * Move ICompileRequest functions to end

2024-07-31Feature/replayer (#4750)kaizhangNV
* record/replay: Implement the json consumer Finish the implementation of json consumer. Fix some bug in the block processing as Tailer is not a necessary block so if the Magic bit is "HEAD", we should keep processing. * record/replay: Implement the replayer component Implement the replayer consumer, and also finish the slang-replay standalone app that will run the while replayer. It can take an option "--convert-json | -cj" which will convert the record binary file to a human readable json file. If there is no option provided, it will replay the record file by default.
