* Embed default prelude for CUDA
Slang supports the notion of a "prelude" that gets prepended to the source code we generate in language. For some targets, a prelude is not necessary (e.g., we compile to HLSL/GLSL and then on to DXBC/DXIL/SPIR-V just fine without a prelude), but some targets have been implemented in a way that makes a prelude necessary (notably CPU and CUDA). For the targets that require a prelude, the Slang codebase includes usable preludes under the `prelude/` directory.
Prior to this change, if a user was compiling for such a target (whether via command-line or API), there had to take responsibility for specifying the prelude to use (usually by passing in the contents of the prelude file(s) already included in the Slang distribution).
It is reasonable for a user to expect an out-of-the-box experience where compilation to CUDA PTX or native CPU code should Just Work, similarly to how compilation to SPIR-V Just Works. This change is a step in the direction of providing a user experiene that Just Works for common cases.
The main addition here is a tool called `slang-embed` that we run during our build to turn the `prelude/*.h` files into `prelude/*.h.cpp` files that embed the contents of the original `.h` file as a `const` variable.
By compiling and linking in the generated `.h.cpp` file for the CUDA prelude, we are then able to set the default prelude to use for CUDA at the time a session/linkage is created. That default prelude will be used unless the user manually specifies their own prelude (which current users of the CUDA back-end must be doing).
This change only sets up a default prelude for CUDA because of the way that the CPU prelude is split across multiple files. A strategy that provides a good default prelude for CPU may take more work, but that work might also be unnecessary if we switch to a strategy of using LLVM to generate native code.
The implementation of the `slang-embed` tool is intentionally simple, and it will likely run into issues if/when we need to embed binary files or larger text files. The assumption being made here is that we can address those issues when they arise, and there is no reason to over-engineer the tool right now.
The way that `slang-embed` is integrated into our build process is likely to require some iteration to make sure that it works across all platforms. I expect that this change will have multiple follow-up fixes related to trying to get the build to work as expected across all targets on CI.
* fixup: trying to ensure that embedded prelude gets compiled into slang
* fixup: properly clean up allocations in slang-embed
* fixup: fix double free introduced by previous change
* fixup: off-by-one allocation error

There was a small but non-trivial amount of code across `IRModule`, the `ObjectScopeManager`, and `StringRepresentationCache` that had to do with managing the lifetimes of `RefObject`s that might be referenced by IR instructions (and thus need to be kept alive for the lifetime of the IR module).
We have long since migrated to a model where IR instruction do not include owned references to `RefObject`s, so these facilities weren't actually needed. This streamlines `IRModule`'s declaration, and trims code that we aren't actually using.
One note for the future is that the `StringRepresentationCache` no longer does what its name implies (it is not a cache of `StringRepresentation`s), so we should consider giving it a more narrowly scoped name. I didn't include that in this change because I wanted to keep the diffs narrow and easy to review.
A follow-on renaming change should be trivial if/when we can agree on what the type should be called at this point. Alternatively, we could simply bake the functionality of `StringRepresentationCache` into he IR deserialiation logic itself, since that is the only code using it.

* Enable use of pre-built glslang binaries
This change uses an updated version of the `slang-binaries` submodule that includes pre-built versions of `slang-glslang.dll` and `libslang-glslang.so`, and enables the build of the main Slang project to rely on these binaries instead of building them from source.
An option to the premake build file can be used to generate the appropriate project files for `slang-glslang`, which should enable us to build updated binaries as needed. The default option is to *not* build those projects, so that we can reduce build times in the common case (and on CI).
* fixup: different copy commands per platform
* fixup
* fixup
* fixup: remove stray line added to premake file by accident

* Added extractLine line parsing to StringUtil. Use for matching lines instead of calcLines. calcLines uses extractLine to extract lines.
Fixed problems found in output of some tests- due to how a how final line is handled. Now a final line has a \r or \n\r combination, but nothing else after it, it is considered the last line (not the line after it).
* Use StringUtil::extractLine in slang-generate.
* Improved comment on extractLine
* Remove test code from StringUtil::extractLine
* Made StringUtil::extractLine act as if line terminators are 'separators'.
Added unit-test-string.cpp - to check behavior.

* Hack to output start of tests.
* WIP parsing CPPCompiler output.
* Make extractLine return a bool.
* First attempt at Visual Studio output parsing.
* Add handling for checking error returning from CPPCompiler.
* First pass parsing output of Gcc/Clang.
* Split out VisualStudioCompilerUtil and GCCCompilerUtil.
Simplified parsing of versions.
* Simplify CPPCompiler::Output interface.
* Fix problem with cpp-compiler on linux targets.

* Improving GCC/Clang parsing output.
* Make cpp compiler parsing function able to return a SlangResult.
* Handling for 'info' on clang
* Add expected result for c-compile-shared-library-error.c
* * Add flags such that link errors on shared libraries are supported.
* Added StringUtil::join
* Turn off the link shared library unfound symbol option on MacOS because it causes an error (and it's not needed on that target).
* Add natvis inclusion back to visual studio projects.
* Display message to try and determine crash problem on travisbuild.
* Fix bug in handling continuations for clang.
Disabled output of exception text.

* Start exposing a new COM-lite API
This change is mostly about exposing a new API to the Slang compiler that allows more fine-grained control over the compilation flow. The basic concepts in the new API are:
* An `IGlobalSession` is the granularity at which we load/parse the Slang stdlib, and therefore gives applications a way to amortize startup cost for the library across multiple compiles. This is a concept that might be able to go away in a future version of Slang.
* An `ISession` owns all the code that gets loaded/compiled/generated. Any `import`ed modules are shared across everything in a session (we don't re-parse/-check the code when we see another `import` for the same module). Any generic- or interface-based code in the session can be specialized using types from the same session (but not necessarily across sessions).
* An `IModule` is the unit of code loading and scoping. It doesn't expose any API in this change, but would be the right scope for looking up types or entry points by name.
* An `IProgram` is a "linked" combination of modules and entry points from which code can be generated and reflection information queried.
This change re-uses the existing reflection API types, rather than introduce a new API that duplicates that functionality. That will probably change in a future revision.
There are two major pieces of functionality added here that aren't related to the new API:
* We now have an API concept of "entry point groups" which are one or more entry points that are intended to be used together so that they need to have non-overlapping parameters. For now this is being used to handle "hit groups" and local root signatures for ray tracing, but I'm not sure this is a concept we will keep in the long run.
* We have a very special-case (client-application-specific) flag that ascribes special meaning to the `shared` keyword, so that it can be attached to global parameters to indicate that they are actually to be part of the local root signature rather than the global one for DXR.
None of the API design (including naming) here is finalized; the only reason to check in the changes at this point to avoid having a long-running branch that leads to merge pain. Clients should *not* try to depend on the new API just yet, since it is still a work in progress.
* fixup: clang warning
* fixup: try to detect clang C++11 support
* fixup
* fixup
* fixup
* fixup
* fixup: review feedback

* Add a warning on missing return, and initial SCCP pass
The user-visible feature added here is a diagnostic for functions with non-`void` return type where control flow might fall off the end. This *sounds* like a trivial diagnostic to add as part of the front-end AST checking, but that can run afoul of really basic stuff like:
```hlsl
int thisFunctionisOkay(int a)
{
while(true)
{
if(a > 10) return a;
a = a*2 + 1;
}
// no return here!
}
```
This function "obviously" doesn't need to have a `return` statement at the end there, but realizing this fact relies on the compiler to understand that the `while(true)` loop can't exit normally, and doesn't contain any `break` statement. One can write "obvious" examples that need more and more complex analysis to rule out.
The answer Slang uses for stuff like this is to do the analysis at the IR level right after initial code generation (this would be before serialization, BTW, so that attached `IRHighLevelDeclDecoration`s can be used).
When lowering the AST to the IR, we always emit a `missingReturn` instruction (a subtype of `IRUnreachable`) at the end of its body if it isn't already terminated. The IR analysis pass to detect missing `return` statements is then as simple as just walking through all the functions in the module and making sure they don't contain `missingReturn` instructions.
For that simple pass to work, we first need to make some effort to remove dead blocks that control flow can never reach. This change adds a very basic initial implementation of Spare Conditional Constant Propagation (SCCP), which is a well-known SSA optimization that combines constant propagation over SSA form with dead code elimination over a CFG to achieve optimizations that are not possible with either optimization along.
For the moment, we don't actually implement any constant *folding* as part of the SCCP pass, so we can eliminate the dead block in a case like the function above (and those in the test case added in this change), but will not catch things like a `while(0 < 1)` loop. Handling more "obvious" cases like that is left for future work.
* fixup: warning on unreachable code
* Handle case where user of an inst isn't in same function/code
The code as assuming any instruction in the SSA work list has to come from the function/code being processed, but this misses the case where an instruction in a generic has a use inside the function that the generic produces.
This change adds code to guard against that case.

* Update glslang version
* Fix build for new glslang
The latest glslang required a few changes to our manual build for their code (because we are *not* taking a dependency on CMake).
* Rebuild project files using premake, which picks up a few files added to glslang, but also a few diffs in Slang's own project files in cases where they were edited manually instead of using premake.
* Fix up the declaration our our device limits (which are inentionally set to *not* limit what code passes through our glslang), because the underlying structure definition in glslang has changed. This is a kludgy bit of glslang's design, but it doesn't make sense for us to invest in a more serious workaround.
* Remove the "hack sampler" workaround
When the `GL_KHR_vulkan_glsl` spec was introduced to allow GLSL to be compiled for Vulkan SPIR-V, it made an annoying mistake by leaving a few builtins as taking `sampler2D`, etc. when the equivalent SPIR-V operations only require a `texture2D`, etc. The relevant builtins are:
* `textureSize`
* `textureQueryLevels`
* `textureSamples`
* `texelFetch`
* `texelFetchOffset`
This means that shader code that wanted to use those operations needed to conspire to have a `sampler` handy so they could write, e.g.:
```glsl
vec4 val = texelFetch(sampler2D(myTexture, someRandomSampler), p, lod);
```
when what they really wanted was this:
```glsl
vec4 val = texelFetch(myTexture, p, lod);
```
That is annoying but probably something each to work around for a GLSL programmer, but when cross-compiling from HLSL, you might have an operation like:
```hlsl
float4 val = myTexure.Load(p);
```
in which case a cross-compiler needs to manufacture a sampler out of thin air. If the shader happened to use a sampler for something else you could snag that, but in the worse case you had to cross-compile to GLSL that declared a new sampler.
Slang did this by declaring a sampler called `SLANG_hack_samplerForTexelFetch` (because `texelFetch` is the operation that first surfaced the issue). For complex reasons we *always* define this sampler, even if we turn out not to need it in a particular output kernel. This choice has a bunch of annoying consequences:
* There is *always* a sampler defined in descriptor set zero, because that's where we put the hack sampler, so a user-defined parameter block always has a set number of 1 or greater (see #646).
* The hack sampler shows up in reflection output because users need to size their descriptor sets appropriately to pass along this sampler that won't actually be used if they don't want to get debug spew from the validation layers.
We filed an issue on glslang about this problem, and eventually some kind folks from the gamedev community (who also saw the same problem) defined an extension spec (`GL_EXT_samplerless_texture_functions`) to fix the underlying issue and contributed a patch to glslang to make it support that extension.
This change just backs the hack out of Slang now that we have a glslang version that supports the extension to get past the defect in the original GLSL-for-Vulkan definition. Besides yanking out the code for the hack, we also change the relevant builtins to declare that they require this new GLSL extension (so that we properly request it from glslang when the builtins are used), and fix some reflection test cases that exposed the existence of the "hack sampler."
* Fixup: syntax error in stdlib generator files
* Remove more code for hack sampler
There was logic to ensure we always have a "default" register space/set when cross-compiling, because the hack sampler would need it. This is no longer necessary once we remove the hack sampler.
* Fix expected test output.
Fixing the root cause of issue #646 means that one of our test cases that tickles that issue now produces different output (luckily it can now be used as a regression test for the issue).

The original goal here was to bring up a second example program: `model-viewer`.
While the existing `hello-world` example is enough to get somebody up to speed with the basics of the Slang API (as a drop-in replacement for `D3DCompile` or similar), it doesn't really show any of the big-picture stuff that Slang is meant to enable.
There wasn't any use of D3D12/Vulkan descriptor tables/sets, and there wasn't any use of interfaces, generics, or `ParameterBlock`s in the shader code.
The `model-viewer` example addresses these issues. Its shader code involves generics, interfaces, and multiple `ParameterBlock`s, and the host-side code demonstrates a few key things for working with Slang:
* There is an application-level abstraction for parameter blocks, that combines the graphics-API descriptor set object with Slang type information
* There is a shader cache layer used to look up an appropriate variant of a rendering effect by using parameter block types to "plug in" global type variables
* There is a clear separation between the phases of compilation: a first phase that does semantic checking and enables reflection-based allocation of graphics API objects, followed by one or more code generation passes for specialized kernels.
This example is certainly not perfect, and it will need to be revamped more going forward. In particular:
* The output picture is ugly as sin. We need a plan for how to get this to load better content, perhaps even popping up an error message to note that the required input data isn't present in the basic repository.
* The shader code is too simplistic. There isn't any real material variety, and the `IMaterial` abstraction is completely wrong.
* The use of parameter blocks is facile because there are no resource parameters right now. Fixing that will likely expose issues around interfacing with Slang's reflection API.
* The whole example exposes the issue that Slang's current APIs aren't really designed for the benefit of two-phase compilation (since our many client application has been stuck on one-phase compilation).
* Global type parameters are actually a Bad Idea that we only did for compatibility with existing codebases. We should not be showing them off in an example of the Right Way to use Slang, but the language support for type parameters on entry points is still not complete.
Of course, the majority of the changes here are *not* inside the example applications, and instead involve a major overhaul of the `Renderer` abstraction that is used for both tests and examples. The main thrust of the change is to make the abstraction layer be closer to the D3D12/Vulkan model than to a D3D11-style model. This is important for the `model-viewer` example, since it aspires to show how Slang can be incorporated into a renderer that targets a modern API. The most important bit is actually the use of descriptor sets and "pipeline layouts" a la Vulkan, since without these Slang's `ParameterBlock` abstraction won't make a lot of sense.
Implementation of the abstraction for the various APIs has very much been on an as-needed basis. The current implementation is just enough for the two examples to work, plus enough to get all the tests to pass in both debug and release builds on Windows.
A big missing feature in the API abstraction right now is memory lifetime management. The code had been trending toward something D3D11-like where a constant buffer could be mapped per-frame with the implementation doing behind-the-scenes allocation for targets like D3D12/Vulkan. I'd like to shift more toward a model of just exposing "transient" allocations that are only valid for one frame, because these are more representation of how an efficient renderer for next-generation APIs will work. That transition isn't actually complete, though, so there are problems with the existing examples where `hello-world` is actually scribbling into memory that the GPU might still be using, while `model-viewer` is doing full-on heavy-weight allocations on a per-frame basis with no real concern for the performance implications.
All together, there are a lot of things here that need more work, but this branch has been way too long-lived already, and so I'd like to get this checked in as long as all the tests pass.

* Generate Visual Studio projects using Premake
This change adds a `premake5.lua` file that allows us to generate our Visual Studio solution using Premake 5 (https://premake.github.io/).
The existing Visual Studio solution/projects are now replaced with the Premake-generated ones, and project contributors will be expected to update these by running premake after adding/removing files.
I have *not* changed the Linux `Makefile` build at all, because that file is also used for things like running our tests, so that clobbering it with a premake-generated `Makefile` would break our continuous testing.
Hopefully future changes can switch to a generated `Makefile` and perhaps even add an XCode project as well.
Notes:
* The `build/slang-build.props` file is no longer needed/used, so it has been removed.
* The `slang-eval-test` test fixture wasn't following our naming conventions for its directory path, so it was updated to streamline the Premake build configuration work. This required changes to the `Makefile` as well
* Some seemingly unncessary preprocessor definitions that were specified for `core` and `slang-glslang` have been dropped. We will see if anything breaks from that.
* Possible fixup for Premake vpath issue
Premake's `vpath` feature seems to be nondeterministic about the order it applies filters (because Lua isn't deterministic about the order of entries in a key/value table), and as a result we can end up in a weird case where it decides that a `foo.cpp.h` file matches the `**.cpp` filter (I'm not sure why) before it tests against the `**.h` filter.
This change uses an (undocumented) Premake facility to set `vpath` using a list of singleton tables, which seems to fix the order in which things get tested.
* Remove support for "single-file" build of Slang
The `hello` example was the only bit of code that uses the "single-file" way of building Slang, and this had already run up against limitations of the Visual Studio compilers in its Debug|x64 build.
Rather than mess with Premake to make it pass through the `/bigobj` linker flag that is needed to work around the issue, it makes more sense just to stop using/supporting the feature since we wouldn't want users to depend on it anyway (our documentation no longer refers to it).
While I was at it I went ahead and made sure that the `SLANG_DYNAMIC` flag doesn't need to be set manually, so that instead there is a non-default `SLANG_STATIC` option (not that we have a static-library build of Slang at the moment).

First pass at fixing problems with Texture creation for dx12 - assertions were hit with 3d or array textures.
* Fixes to improve Dx12 setup shader resource views for cubemaps/arrays.
* Fixed d3d12 textureSamplingTest - problem was that cubemap/array textures were not being uploaded correctly.
* Changed the order of how binding of constant buffers (as just set on the Renderer) indexes. Previously they were given the lowest indices, but they clashed with the indices from the 'Binding'. Changing this means all tests run on d3d12.
* Add code to allow use of warp (although not command line switchable yet).
Fix problem setting up raw UAV - as identified by warp.
* Added RenderApiUtil - which can detect if a render api is potentially available.
* Moved render flag testing/parsing into RenderApiUtil.
* Fix signed/unsigned warning.
* Fixes around enums prefixed with k on the review of feature/dx12 compute branch.

* Fix signed/unsigned comparison warning.
* Split out d3d functions that will work across dx11 and 12.
* Improve slang-test/README.md around command line options.
* Make Guid comparison honor alignment for comparisons, such that mechanism work on architectures that can only do aligned accesses.
* Initial setup of D3D12 Renderer, with presentFrame and clearFrame.
* More support for D3D12
* Added FreeList
* Added D3D12CircularResourceHeap
* First attempt at createBuffer
* First pass at map/unmap.
* First pass binding vertex/constant buffers, and setting up InputLayout. Note that memory is not kept in scope on binding yet.
* First pass of D3DDescriptorHeap
* Small tidy up in render-d3d11. Added D3DDescriptorHeap to project.
* First pass at D3D12 bind state.
* Fix typos in D3D12Resource
* Tidy up Dx11 render binding a little to match more with Dx12 style.
* First pass at Dx12 BindingState
* Handling of the command list d3d12. Support for submitGpuWork and waitForGpu.
* First attempt at Dx12 capture of backbuffer to file.
* First attempt at D3D12 binding for graphics.
* D3D12 setup viewport etc - does now render triangle in render0.hlsl.
* First pass at support for compute on D3D12Renderer
* Use spaces over tabs in D3DUtil
* Tabs to spaces in D3D12DescriptorHeap
* Convert tab->spaces on render-d3d12.cpp

* Fixed some small typos in api-users-guide.md
* Fix some small typos in slang-test/main.cpp, render-test/render-d3d11.cpp
* Remove exit() calls from test code. Added Slang::Result, which works in the same way as COM HRESULT.
* FIx bug introduced when moving to Slang::Result - handling E_INVALIDARG on Dx11.
* Fix the testing of feature levels on Dx11 renderer.
* First attempt at README.md for slang-test.
* Tidied up the slang-test README.md file.
* Fix some small typos in tools/slang-test/main.cpp
* Fix spaces -> tabs problems.
Fix some small types.
* Refactor Renderer implementations such that:
* Class definition does not contain long implementation/s
* Removed unused globals
* Ordered implementation after class definition
* Made renderer specific classes child classes, and use Impl postfix to differentiate
* Converted tabs into spaces
* First pass at Slang::ComPtr. Added slang-defines.h which sets up some fairly commonly used defines such as SLANG_FORCE_INLINE, compiler detection, os detection, and some other cross platform features.

* First attempt at a Linux build
- Fix up places where C++ idioms were written assuming lenient behavior of Microsoft's compiler
- Add a few more alternatives for platform-specific behavior where Windows was the only platform accounted for.
- Add a basic Makefile that can at least invoke our build, even if it isn't going good dependency tracking, etc.
- Build `libslang.so` and `slangc` that depends on it, using a relative `RPATH` to make the binary portable (I hope)
- Add an initial `.travis.yml` to see if we can trigger their build process.
* Fixup: const bug in `List::Sort`
I'm not clear why this gets picked up by the gcc *and* clang that Travis uses, but not the (newer) gcc I'm using on Ubuntu here, but I'm hoping it is just some missing `const` qualifiers.
* Fixup: reorder specialization of "class info"
Clang complains about things being specialized after being instantiated (implicilty), and I hope it is just the fact that I generate the class info for the roots of the hierarchy after the other cases. We'll see.
* Fixup: add `platform.cpp` to unified/lumped build
* Fixup: Windows uses `FreeLibrary`
and not `UnloadLibrary`
* Fixup: fix Windows project file to include new source file
This obviously points to the fact that we are going to need to be generating these files sooner or later.

It is always easier to add back code when you need it, than it is to maintain code you aren't using.

Getting rid of more namespace complexity and stripping things down to the basics.
This also gets rid of some dead code in the "core" library.
|
| |
|
|
| |
All of this is just related to cruft left over from the old project setup.
