2024-07-25Disallow multi-dim vector subscript in slang IR (#4277)Sriram Murali
Fixes bug #3180 This test verifies the check for illegal swizzle on vector types, whose element is not a basic Type (int, float). The check captures the failure within swizzle access on a nested vector subscript element. vector<vector<int, 2>, 2> a int b = a[0].x; // illegal Co-authored-by: Yong He <yonghe@outlook.com>
2024-07-25Add `_Internal`/`External` atom enforcement and validation. (#4702)ArielG-NV
* Add `_Internal`/`External` atom validation and use enforcement. Fixes: #4676 Changes: * Added `validateInternalAtomExternalAtomPair` to the capability generator to ensure all `_Internal` atoms have a corresponding `External` atom. * Validation of 'RequireCapabilityAttribute' warns if a user uses an '_Internal' atom. * Added 'External' atoms to atoms with an already existing '_Internal' atom. * Printing an atom removes '_'. * Fixed some incorrect which were checking for the incorrect warning/error (capability4.slang, capability5.slang, capability6.slang). * switch capability name to use `UnownedStringSlice` instead of `const char*` switch capability name to use `UnownedStringSlice` instead of `const char*`, this includes using functions like `.startsWith`. * grammer --------- Co-authored-by: Yong He <yonghe@outlook.com>

2024-07-24Support 1-dimensional matrix for HLSL (#4728)Jay Kwak
Closes #4395 This commit allows Slang to use 1-dimensional matrix when targetting HLSL. The 1-dimensional matrix is supported by DXC natively. GLSL/Vulkan doesn't support the 1-dimensional matrix natively. It is not trivial for Slang to convert all of matrix functions to vector or scalar at the emitting step. We can implement this later if there are needs. This commit disallows the use of 1-dimensional matrix for targetting GLSL/Vulkan by the capability system; in other words, the new 1-dimentional functions have "[require(hlsl)]".

2024-07-24Fix checking of var with matrix layout modifier. (#4737)Yong He
2024-07-23Allow only specific spv storage classes for binding decoration (#4713)kaizhangNV
* Allow only specific spv storage classes for binding decoration In https://registry.khronos.org/vulkan/specs/1.3/html/chap37.html#VUID-StandaloneSpirv-DescriptorSet-06491 it states that If a variable is decorated by DescriptorSet or Binding, the Storage class must be UniformConstant, Uniform and StorageBuffer. So apply this rule to our emit-spirv logic. * Add a unit test * Address few comments
2024-07-23Fix for `ConstantBuffer<T[...]>` causing a segfault (#4705)ArielG-NV
Fixes: #4704 Change the type we assign when getting the member variable of a legalized `ConstantBuffer<T[...]>`.
2024-07-23Warn if providing explicit bindings to a object using uniform locations (#4708)ArielG-NV
fixes: #4700 Changes: * If a uniform object (which uses uniform locations) has explicit bindings we will warn to use `ConstantBuffer<T>` instead. We check for a warning specifically when we know an object uses uniform layouts because objects may not use a uniform-layout register even if tagged with `uniform`. A good example of this is `uniform ConstantBuffer<T>`.
2024-07-23Simplify `CapabilitySet` Diagnostic Printing (#4678)ArielG-NV
Fixes: #4675 Fixes: #4683 Fixes: #4443 Fixes: #4585 Fixes: #4172 Made the following changes: 1. All capability diagnostic printing logic tries to simplify before printing. This means that we do not print atoms which imply another atom. 2. Do not print the `_` prefix part of atom names since it is misleading users on what they should use to solve a capability issue encountered. (`_Internal` `External` atom changes are not in this PR) 3. Bundle together printing of all sets which contain exactly the same atoms (excluding abstract atoms). This allows printing the following `vertex/fragment/hull/domain/... + glsl` instead of `vertex + glsl | fragment + glsl | hull + glsl | domain + glsl | ....` 4. Rework how entry-point errors are reported to users (example at bottom of PR comment) 5. Rework how atom-provenance data is collected to be leaner and more useful so we can rework the errors. There are 2 notable changes here: * We no longer store a list which describes where the first of an `CapabilityAtom` comes from. This heavily simplifies AST logic for the capability system. AST parsing of capabilities is much faster. The trade-off is faster AST parsing and correct AST node data for slower diagnostics if an error is found * atom-provenance data now stores a reference to an atom's use-site to provide information on **where** and **what** is wrong with user code versus only sharing **what** and not where.

* Support parameter block in metal shader objects. * Ingore parameter block tests on devices without tier2 argument buffer. * Fix warning. * Fix texture subscript test. --------- Co-authored-by: Yong He <yhe@nvidia.com>
2024-07-19Fix the issue of name mangling (#4691)kaizhangNV
* Fix the issue of name mangle During our name mangling, we should add the direction of the parameter in the name, otherwise it could have the name collision which will result in invalid code generation: e.g. // in slang-module.slang export func(float a) { ...} // in test.slang extern func(inout float a); when we compile test.slang, slang will pass a pointer type to the 'func', however, in the slang-module.slang, `func` expects a value instead of pointer. This will lead the wrong spirv code. So we should add the parameter direction into the mangle name such that above two symbols will have the different mangled names, and we will catch this during IR-link stage. * Change to use to get param direction * Address few comments
2024-07-18Metal: `Interlocked` (atomic) member function support for buffers (#4655)ArielG-NV

2024-07-18Allow CPP/CUDA/Metal to lower/legalize buffer-elements to support ↵ArielG-NV
column_major/row_major. (#4653) * Allow CPP/CUDA/Metal to legalize their buffer-elements. Fixes: #4537 Changes: 1. Matrix inputs require legalization (pack/unpack) to ensure consistent row_major/column_major throughout entire shader, the following enabled legalization pass fixes this. 2. Added missing CUDA intrinsic so CUDA can run more tests. 3. Added a memory packing test since this still fails for cpp/cuda/metal (due to having no memory packing enforcement). * change memory packing tests to run for targets without packing --------- Co-authored-by: Yong He <yonghe@outlook.com>

2024-07-18Support OpDebugTypePointer for struct member pointer (#4527)Jay Kwak

2024-07-18Adjust how `slang` and `slangc` uses a `profile` to manage the stage of an ↵ArielG-NV
entry-point (#4670) * Fixes #4656 Changes: 1. Setting a profile via slangc no-longer sets an entry-point target-stage, this is to allow slangc to follow how the SLANG-API works (else `main` is assumed to be the default entry-point) 2. If the stage specified by a profile is not equal to the stage specified by a entry-point, we throw a capability error. 3. Resolving the stage of an entry point was changed to function (mostly) equally for when 0 entry-points are specified versus to when there are 1 or more. 4. changed capabilitySet Iterator so it is invalid if backing data is nullptr (although this should never happen, it would stop crashes in the worst case). * remove the breaking change since it likely is going to be a lot more than just a simple change due to the implicit `main` and stage through `profile` code. * print out profile name with errors * use target's profile for printing * change logic to print warning in a different method (account for more cases) * set unknown stages

2024-07-10Fix lowering of associated types and synthesis of dispatch functions. (#4568)Sai Praveen Bangaru
* Treat global variables and parameters as non-differentiable when checking derivative data-flow Global parameters are by-default not differentiable (even if they are of a differentiable type), because our auto-diff passes do not touch anything outside of function bodies. The solution is to use wrapper objects with differentiable getter/setter methods (and we should provide a few such objects in the stdlib). Fixes: #3289 This is a potentially breaking change: User code that was previously working with global variables of a differentiable type will now throw an error (previously the gradient would be dropped without warning). The solution is to use `detach()` to keep same behavior as before or rewrite the access using differentiable getter/setter methods. * Fix issues with lookup witness lowering * Update slang-ir-lower-witness-lookup.cpp * Add tests * Update slang-ir-lower-witness-lookup.cpp * Cleanup * Update nested-assoc-types.slang --------- Co-authored-by: Yong He <yonghe@outlook.com>
2024-07-10Implement non member function atomic texture support (#4544)ArielG-NV
* Implement non member function atomic texture support texture_buffer and texture1d Fixes: #4538 Related to: #4291, fixes `tests/compute/atomics-buffer.slang` Texture objects cannot use `__getMetalAtomicRef` to cast objects into atomic value type. [Texture objects mandate use of member functions](https://developer.apple.com/metal/Metal-Shading-Language-Specification.pdf#Texture%20Functions). The implementation is as follows: * We can detect texture object usage through checking for an `IRImageSubscript` Operation. `__isTextureAccess()` was added to evaluate if we have an `IRImageSubscript` operation at compile time (before `static_assert`). `__isTextureAccess()` only checks if we are targeting Metal. * We have all parameter data needed to call a texture atomic function embedded inside `IRImageSubscript`. `__extractTextureFromTextureAccess()` and `__extractCoordFromTextureAccess()` was added to extract this data for use with Metal atomics. Note: * Metal documentation has various incorrect details (function names) * Since we currently hardcode metal versions for compiling, the Metal compiler version was changed to target `Metal 3.1` (`slang-gcc-compiler-util.cpp`) * textures do not permit atomic float operations * add fallthrough attribute + fix bug with 'exchange instead of xor' + fix warning bug * incorrect function name fix * missing filecheck * disable atomics-buffer.slang compute test since GFX issue causing it to fail * Array support for metal interlockedAtomic and proper verification of texture with interlockedAtomic functions * Array support for metal interlockedAtomic * proper verification of texture with interlockedAtomic functions note: had to seperate many functions to allow forceInlining to run * missing getOperand(0) * push atomic fix for metal * fix atomic syntax for metal and hlsl emitting extra brackets (breaks tests) * test changes and meta changes 1. max is 8 rw textures with metal because Metal has this limit. Split up tests to not hit this limit 2. added back `[0]`...,`T` to test since this legalizes metal atomic intrinsic * macro'ify some of the atomic code 1. addresses review 2. makes code easier to modify in the future (rather than sifting through 1000 lines we can just look at ~10-30 * fix test 'check' * missing float support due to macro * add functions macro generates, `InternalAtomicOperationInfo` --------- Co-authored-by: Yong He <yonghe@outlook.com>
2024-07-10Fixes to Metal Input parameters and Output value input/output semantics (#4536)ArielG-NV
* initial change to test with CI for CPU/CUDA errors * Fixes to Metal Input parameters and Output values Note: 1. Flattening a struct is the process of making a struct have 0 struct/class members. Changes: 1. Separated `legalizeSystemValueParameters`. This was done to make it easier to run `legalizeSystemValue` 1 system-value at a time to simplify logic. This change is optional and can be undone if not preferred. 2. Wrap everything inside a Metal legalization context. This was done since it simplifies a lot of logic and will be required for #4375 3. Created `convertSystemValueSemanticNameToEnum` and expanded the existing System-Value Enum system. This allows (sometimes) faster comparisons and helps prepare code for porting into `slang-ir-legalize-varying-params.cpp` (#4375) 4. Added a more dynamic `legalizeSystemValue` system so more than 2 types can be targeted for legalization. This is required to legalize `output`. There is still no preference for any converted type, the first valid type will be converted to. 5. Flatten all input(`flattenInputParameters`)/output(part of `wrapReturnValueInStruct`) structs and assign semantics accordingly. 6. Semantics when legalized have no specific logic other than to: 1. avoid overlapping semantics 2. Prefer assigning explicit semantics specified by a user. 7. Fixed some issue with incorrect output semantics if not a fragment stage (when there are not any assigned semantics) * change metallib test to the correct metal test * comment code & cleanup -- Did not address all review Added comments for clarity + cleaned up some odd areas which were messy * Add comment to `fixFieldSemanticsOfFlatStruct` I found `fixFieldSemanticsOfFlatStruct` to still be confusing at a cursory glance. Added comments to make the function be more understandable. * white space * Address review comments 1. Fix semantic propegation. 2. Fix how we map struct fields of the flat struct to struct. This is specifically important for if reusing the same struct twice since struct member info is not unique per struct instance used. * Fix semantic legalization by adding TreeMap Add TreeMap to allow proper sorted-object data iteration. * Fix some compile issues * try to fix gcc compile error * compile error * fix logic bug in treeMap iterator next-semantic setter * fix vsproject filters * filter file syntax error * remove need of a context to make copies stable * Rename treemap to the more appropriate name of "treeset", adjust code comments accordingly. * remove custom type `TreeSet` and use `std::set` * remove TreeMap fully --------- Co-authored-by: Yong He <yonghe@outlook.com>

2024-07-09Warnings for uninitialized values (#4530)venkataram-nv
This extends the code for handling uninitialized output parameters. Still needs to handle generic templates and assignment of uninitialized values more carefully. The file containing the relevant code are now in source/slang/slang-ir-use-uninitialized-values.cpp rather than the previous source/slang/slang-ir-use-uninitialized-out-param.h and the top-level function is now checkForUsingUinitializedValues. Additionally a rudimentary test shader has been added for this case, which replaces the old file for out params only; tests/diagnositcs/uninitialized-out.slang becomes tests/diagnositcs/uninitialized.slang. What this does not implement (could be future PRs): * Checking uninitialized fields within constructors * Partially uninitialized values with respect to data structure (e.g. arrays/structs/vector types) * Partially uninitialized values with respect to control flow (e.g. if/else/loop)
