2025-02-07Use and() and or() functions for logical-AND and OR (#6310)Jay Kwak
* Use and() and or() functions for logical-AND and OR With this commit, Slang will emit function calls to `and()` and `or()` for the logical-AND and logical-OR when the operands are non-scalar and the target profile is SM6.0 and above. This is required change from SM6.0. For WGSL, there is no operator overloadings of `&&` and `||` when the operands are non-scalar. Unlike HLSL, WGSL also don't have `and()` nor `or()`. Alternatively, we can use `select()`.

2024-10-15 Move C interface from slang.h to slang-deprecated.h (#5301)Ellie Hermaszewska
* Squash redundant move warnings * Move C interface from slang.h to slang-deprecated.h spGetBuildTagString remains, because it's useful to have before the global session exists. This C API is used quite pervasively in the C++ helpers (for example slang::UserAttribute. It's not trivial to move these to slang-deprecated.h as they're entangled with some enums which are themselves used elsewhere in the compiler. The fact that these helpers use the C API can be viewed as an implementation detail for now, and this usage moved to slang-deprecated in due course. Closes https://github.com/shader-slang/slang/issues/4758 * Squash warnings for our usage of our deprecated API --------- Co-authored-by: Yong He <yonghe@outlook.com>

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

2024-07-10Fixes 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>
2024-06-26Expand upon existing `ImageSubscript` support (Metal, GLSL, SPIRV) (#4408)ArielG-NV
* Add additional `ImageSubscript` features: 1. Added ImageSubscript support for Metal & a test case * Merge GLSL/SPIRV/Metal `ImageSubscript` legalization pass 2. Added multisample support to glsl/spirv/metal for when using ImageSubscript * Added in this PR since the overhaul of the code merges together GLSL/SPIRV/Metal implementation 3. Fixed minor metal texture `Load`/`Read` bugs * [HLSL methods of access do not support subscript accessor for texture cube array](https://learn.microsoft.com/en-us/windows/win32/direct3dhlsl/texturecubearray) * removed swizzling of uint/int/float * other odd bugs which were causing compile errors note: Compute tests do not work due to what seems to be the GFX backend (causes crash without error report). The tests are disabled. * disable LOD with texture 1d seems that LOD for 1d textures need to be a compile time constant as per an error metal throws * syntax error in hlsl.meta * static_assert alone with intrinsic_asm error provides cleaner errors Note: `static_assert` seems to be unstable and not be fully respected (still require `intrinsic_asm` to avoid a stdlib compile error) * change comment to `// lod is not supported for 1D texture * add `static_assert` in related code gen paths * address review * address review * add asserts as per review comment, NOTE: unclear if these should be release 'asserts' as well
