There were multiple early-out `if` cases that accidentally fell through to the fallback path, so that symbol names would end up being excessively long. * Fix type conversion cost lookup cache, by allowing single-element vectors (e.g., `vector<float,1>`) and single row/column matrix types to be distinguished from types of lower rank.

389d21d Theresa Foley 11 August 2021, 19:24:43 UTC Handle unexpected character in mangled names (#1919) This change is related to a case where a user saw a `/` character printed as part of a structure field name in output HLSL (which obviously broke downstream compilation). The root cause in that case was that a module that was `import`ed was found via a file system directory path, and thus the module name that the Slang compiler formed included a `/`. Due to other factors the structure field was emitted based on its mangled name (missing name hint), and that meant the bare `/` escaped into the output. That situation implies some other things maybe are questionable: * Could we have avoided a `/` ending up in the module name to begin with? Maybe, but we kind of want to support non-ASCII characters in names in the long run. * Could we have fixed whatever was causing the name hint to be dropped? Maybe, but we don't ever want name hints to be *required* for valid compilation (hence why they are "hints"). Even if we investigate these other issues, it is important that the name mangling scheme only ever produce output that uses a constrained subset of ASCII that we expect most compilation targets can support (GLSL being an annoying outlier because of its rules around `_`). This change adds a path where when mangling a `Name` as part of a mangled symbol name we check for the presence of bytes that aren't allowed and then produce an escaped form instead if needed. Note that the code is still byte-oriented for now aothough in the long-run it might want to be oriented around Unicode code points or extended grapheme clusters. 11 August 2021, 19:24:43 UTC
4323a15 Theresa Foley 11 August 2021, 18:00:16 UTC Fix a few issues around opaque types as outputs (#1918) * Fix a few issues around opaque types as outputs Slang and HLSL support opaque types (textures, buffers, samplers, etc.) as members of `struct`s, mutable local variables, function results, and `out`/`inout` parameters. GLSL and SPIR-V do not. In order to translate Slang code over to GLSL/SPIR-V we use a variety of passes that seek to eliminate all of the above use cases and produce code that only uses opaque types in the limited ways that GLSL/SPIR-V allow. This change relates to the passes that deal with function results and `out`/`inout` parameters. There are two basic changes here: 1. The `specializeResourceOutputs` pass was only dealing with resource (texture/buffer) types. This change updates it to process sampler types as well. 2. The sequencing of the passes made it possible that an opaque-typed local variable might be left around after `specializeResourceOutputs`, which would mean the code is still invalid for GLSL/SPIR-V. This change adds an additional SSA-formation pass which would eliminate any opaque-type local variables whose lifetimes were made simple enough by the optimizations. Together these changes fix a problem-case user shader that was failing to compile for Vulkan. * Update slang-emit.cpp Fix typo 'reuslt' * Update slang-emit.cpp Comment change to re-trigger CI build.

23d406f Theresa Foley 21 July 2021, 19:52:08 UTC Work to mitigate SPIR-V bloat (#1914) * Work to mitigate SPIR-V bloat SPIR-V is not an especially compact format, but some patterns in how Slang generates code and then runs it through `spirv-opt` lead to many redundant field-by-field copy operations being emitted. This change attempts to address some of the resulting bloat from the Slang side of things. Note: experimentation shows that the bloat is less pronounced when running either *no* SPIR-V optimizations or *full* SPIR-V optimizations, so it is also likely that the bloat should be addressed by changing which `spirv-opt` passes the Slang compiler runs in default (`-O1`) builds. Such changes should come as a distinct pull request. This change primarily does two things: First, the code generation strategy for passing arguments to `out` and `inout` parameters has been changed. In the past, the compiler would *always* copy the argument value into a temporary, then pass the address of the temporary, and then write back the value after the call. The new code generation strategy attempts to identify when an argument value already has a simple address in memory and passes that address directly when possible. This eliminates many copy operations that occur before/after calls to functions with `out`/`inout` parameters. Second, we introduce an IR optimization pass that detects call sites where the entire contents of a buffer (usually a constant buffer) is being passed to a callee function, such that many bytes are loaded and then passed even if only very few are used in the callee. The pass moves the load operations from the caller to a specialized version of the the callee where possible (e.g., when the constant buffer in question is a global shader parameter). Doing this eliminates another major category of copies. Notes: * The IR lowering logic is complicated by the fact that several kinds of l-values (values that are usable as the desitnation of assignment, or for `out`/`inout` arguments) are not actually addressable. An easy example is a non-contiguous swizzle like `v.xwz` on a `float4`, where the value occupies 12 bytes, but not 12 consecutive bytes with a single address. There are many more corner cases like that and the IR lowering pass carries a lot of complexity to deal with them. A more systematic overhaul is due some time soon. * The IR representation of `out` and `inout` parameters deserves some careful scrutiny when making these kinds of changes. The official semantics of `inout` in HLSL has been "copy in copy out" (and `out` is just "copy out") which is observably different from any solution that passes in the address of an l-value directly. By making this change we are saying that Slang's semantics are not precisely those of legacy HLSL, and that our semantics for `inout` parameters are closer to those of `inout` in Swift or of a mutable borrow in Rust. In the Swift case the implementation can freely pass the underlying storage of an l-value or the address of a temporary, and valid programs may not observe the different. It is thus illegal to observe the value in a storage local while a mutation to that location is "in flight." All of this is way more detailed and technical than 99% of Slang users will ever care about, but importantly it gives us semantic cover to eliminate these copies in the IR, and also to emit output C++ code that implements `out` and `inout` as by-reference parameter passing. * There was an exsting generic pass for specializing functions based on call sites that uses a "template method" style of pattern to customize its behavior. That pass needed to be generalized to handle this use case because it had previously operated on the assumption that the "desire" to specialize a callee function must be driven by the parameter declarations of that function, and not on the argument values passed in. The code has been slightly refactored to allow the policy for specialization to consider both parameters and arguments. * Unsurprisingly, a bunch of the GLSL (and thus SPIR-V) generated has changed with this work, so several baseline `.slang.glsl` files needed to be updated. * This change is incomplete in that it does not address broader cases of buffer loads, including both partial loads from constant buffers (just loading one field, but a field that uses a "large" structure type), and loads from multi-element buffers (a lot from a structured buffer where the element type is "large"). The main question in each of those cases is how to define how "large" a structure needs to be before we decide to try and sink loads into callee functions like this. In the worst case, sinking loads in this way may actually create *more* memory traffic (because the same values get loaded in multiple callee functions). * fixup: run premake * fixup: typo 21 July 2021, 19:52:08 UTC

9dfaabe Theresa Foley 25 June 2021, 22:50:29 UTC Fixes related to combined texture/sampler types (#1894) * Fixes related to combined texture/sampler types Work on #1891 Our intention has always been to support combined texture/sampler types in Slang, both targets like OpenGL where that is the only option available and for targets like Vulkan where it can be beneficial to performance. Because Slang's current users mostly focus on D3D12+Vulkan codebases, they strongly prefer separate textures and samplers, and the relevant support code in Slang has "bit-rotted" over many releases until the functionality that was there isn't useful any more. This change significantly overhauls the implementation of combined texture/sampler types and adds a test that uses them in the hopes of avoiding future regressions. The new combined texture/sampler types use the prefix `Sampler`, so where there is an existing standalone `Texture2D` type the equivalent combined texture/sampler type will be `Sampler2D`. The intention is that this naming mirrors the GLSL conventions (where the type is `sampler2d`) while following HLSL naming precedent (to the extent it exists). The operations available on a `Sampler2D` are intended to be those that are available on a `Texture2D`, and it is just that in cases where the `Texture2D` operation would take a separate sampler argument: Texture2D t = ...; SamplerState s = ...; float4 result = t.Sample(s, uv); the equivalent `Sampler2D` operation just elides that argument: Sampler2D s = ...; float4 result = s.Sample(uv); In terms of implementation, there are a lot of subtle details here: * I've tried to use the same metaprogramming logic that generates all the stdlib declarations for `Texture*` to also generate `Sampler*` in the hopes that this helps keep them in sync. * The big catch to the above is that it means that for certain operations the indidces of parameters depend on whether or not an explicit sampler parameter is used. Rather than try to tweak the indices in the stdlib generation logic (which is already complicated) I went and added Yet Another Hack to the logic that handles intrinsic definition strings. Basically, the special-case handling of `$p` has been modified so that it *also* applies a negative offset to future parameter references in the same intrinsic string. * Trying to actually bring this up in our test framework revealed that the "flat" reflection API was seemingly not reflecting combined texture/sampler types correctly at all (it was reflecting them as just plain textures). Other than that issue, the Vulkan path seems to work fine with combined texture/samplers. * I also had to add logic to the `TEST_INPUT` parsing to re-introduce handling of the combined types (that was something I consciously left out to reduce the amount of code in the earlier refactor there). Luckily, the architecture is such that a combined texture/sampler can leverage most of the existing logic for the separate cases. * fixup: reveiw feedback 25 June 2021, 22:50:29 UTC

8905125 Theresa Foley 16 June 2021, 21:35:25 UTC Initial support for variadic macros (#1887) This change adds support for variadic macros in the C-style preprocessor, e.g.: #define DEBUG(MSG, ...) print(__FILE__, __LINE__, MSG, __VA_ARGS__) Similar to the gcc preprocessor, this feature supports both named variadic macro parameters and unnamed ones (which then default to `__VA_ARGS__`. The implementation work is mostly straightforward, although there are a few subtle design choices worth mentioning: * A variadic macro is represented by it having a variadic *parameter* that is part of the ordinary parameter list. * Argument parsing does *not* detect whether the macro being invoked is variadic and collect/combine arguments to form a single argument value for the variadic parameter. This is motivated by the need for some extensions to differentiate a variadic parameter receiving a single empty argument vs. zero arguments. * Because any reference to the variadic parameter needs to expand to the comma-separated arguments that match it, the logic for turning a macro parameter reference into a list of tokens has been factored out into a subroutine that handles the details. * The choice in the earlier refactor to have a macro invocation collect all the argument tokens (including the intervening commas) into a single token list seems to pay off here, because it means that the tokens in the expansion of a variadic parameter reference were already stored contiguously. * The special-case logic for handling an empty argument list had to be tweaked again to ensure that an empty argument list is treated as having zero arguments for the variadic parameter. Note that historically C did not define the behavior of this case, and always required at least one argument for any variadic macro parameter. * The logic for checking whether the number of arguments to a macro invocation is valid needed to handle variadic and non-variadic macros as distinct cases. There really isn't much overlap in how the checks need to work, even if we tried to change the underling representation. The main missing feature here is any way to discard a comma in a macro body that appears before a variadic parameter reference, e.g.: #define DEBUG(...) print("debug:", __VA_ARGS__) In this case, an empty invocation list `DEBUG()` will expand to `print("debug:",)` - a call with a trailing comma in the argument list. If users end up needing a way to discard commas in cases like this, we have many options we can consider. This change does not implement any of them to keep the initial work as minimal as possible. 16 June 2021, 21:35:25 UTC

6cee1ee Yong He 08 June 2021, 14:44:05 UTC Various fixes to CUDA backend. (#1877) - Fix emitting `StructuredBuffer<ISomething>::Load`, which triggers emitting for `IROp_WrapExistential` that is previously unhandled. - Fix cuda layout around vectors, they should be aligned to 1,2,4,8,16 bytes instead of just using element type's alignment. That means `float4` has alignment of 16 instead of 4. - Fix `SLANG_CUDA_HANDLE_ERROR` macro definition. - Fix navis sometimes fail to find `Slang::kIROp_*` enum values when debugging external projects.

688d5fa T. Foley 06 June 2021, 16:27:19 UTC Include a "stack trace" with nested-import errors (#1872) * Include a "stack trace" with nested-import errors When errors occur in nested `#include` files it is often helpful to have a "stack trace" / traceback of the `#include` chain that led from a root translation unit to the file with an error. This change implements a similar feature for `import`s. It is worth noting that `import`s don't really *require* this kind of compiler support the way `#include`s do because the intention is that the meaning of an `import`ed file does not depend on the order or nesting of `import`s. As such, when trying to *fix* an error in an `import`ed file, you usually don't care how it came to be `import`ed into your shaders. The use case here is somebody adapting a large body of Slang code to use in a different codebase, such that they have certain `.slang` files they don't actually intend to have compile correctly, and they want to be able to diagnose how they came to include those files when/if they cause problems. The actual feature implementation is pretty simple because we already track a stack of active `import`s so that we can detect and diagnose recursive `import`s. This change simply changes the disagnostics when there is an error in imported code so that instead of just noting the inner-most `import` site it lists all the `import` sites that were active at the time. The change includes a test case to confirm that the behavior works (at least for the case of a parse error). * fixup: test outputs Co-authored-by: Yong He <yonghe@outlook.com> Co-authored-by: jsmall-nvidia <jsmall@nvidia.com> 06 June 2021, 16:27:19 UTC
58d7af3 T. Foley 06 June 2021, 15:59:28 UTC Fix a bug in preprocessor "busy" logic (#1875) * Fix a bug in preprocessor "busy" logic This bug manifested in both incorrect preprocessor output for certain complicated cases, and also (more importantly) a use-after-free issue. One of the "clever" design choices in the Slang preprocessor implementation is that the set of "busy" macros during expansion is implicitly defined by a linked list of those invocations that are actively being read from as part of the input stack. This logic works very well for checking whether a macro name is busy before triggering expansion, and for computing what macros should be considered busy during expansion of an object-like macro. The problem case here was with function-like macros where the preprocessor was re-using the same list of busy macros that had been fetched when reading the macro name, but doing so *after* all the macro argument tokens had been read. Because additional tokens had been read from the input stream stack, there was no guarantee that the invocations that had been active before were still live. The new logic computes the set of busy macros fresh before starting expansion of a function-like macro invocation. A test is included to ensure that the case that showed the use-after-free bug has been fixed. In addition, the new logic is careful to compute the busy macros only based on where subsequent tokens will come from and not based on any macros that might have contributed to the argument tokens themselves. A test case has been added that relies on getting this detail correct. * Update slang-preprocessor.cpp Remove a test typo. Co-authored-by: jsmall-nvidia <jsmall@nvidia.com> 06 June 2021, 15:59:28 UTC
