Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2025-10-03T04:48:11+00:00 2025-10-03T04:48:11+00:00 Theresa Foley 10618364+tangent-vector@users.noreply.github.com 2025-10-03T04:48:11+00:00 urn:sha1:cc8f6a241edb47c43c5698ee33abed4fe57d4566 Note that while this change touched a large numer of files, there are no changes to functionality being made here. The only things being done are renaming various symbols and, in a few cases, updating or adding comments for consistency with the new names. The core of the naming changes are: * Most things named to refer to `OutType` (e.g., `IROutType`, `IRBuilder::getOutType()`, etc.) have been consistently renamed to refer to `OutParamType`, to emphasize that the relevant AST/IR node types are only intended for use to represent `out` parameters. * The same change as described above for `OutType` is also made for `RefType`, which becomes `RefParamType` in most cases. One mess that this exposes is the way that the `ExplicitRef<T>` type in the core module currently lowers to `IRRefParamType`. This change sticks to the rule of not making functional changes, so that mess is left as-is for now. * Names referring to `InOutType` have been changed to instead refer to `BorrowInOutType`. The intention with this naming change is to emphasize that the Slang rules for `inout` are semantically those of a borrow (or at least our interpretation of what a borrow means). * Names referring to `ConstRefType` have been changed to instead refer to `BorrowInType`. This change starts work on clarifying that the existing `__constref` modifier was never intended to be a read-only analogue of `__ref`, and instead is the input-only analogue of `inout`. * The `ParameterDirection` enum type has been changed to `ParamPassingMode`, to reflect the fact that the concept of "direction" fails to capture what is actually being encoded, particularly once we have modes beyond simple `in`/`out`/`inout`. While this change does not alter behavior in any case (the user-exposed Slang language is unchanged), it is intended to set up subsequence changes that will work to make the handling of these types in the compiler more nuanced and correct. Breaking this part of the change out separately is primarily motivated by a desire to minimize the effort for reviewers. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> 2025-08-07T07:22:22+00:00 ArielG-NV 159081215+ArielG-NV@users.noreply.github.com 2025-08-07T07:22:22+00:00 urn:sha1:063cbeaaea2fb00a10c6058ea4a9632092772ea5 Fixes #7574 Changes: * Add an initial (fairly simple) optimization pass which is able to eliminate redundant copies. * Our current existing optimizer passes remove redundant load/store very robustly, this pass will focus on other cases of copy elimination * Primary approach is to make all functions which are `in T` and `T` is trivial to copy into a `__constref T`. We then (depending on scenario) manually insert a variable+load if a pass-by-reference is not possible; otherwise we pass by `constref`. * Added optimizations to eliminate redundant code which causes `constref` to fail to compile --------- Co-authored-by: Harsh Aggarwal <haaggarwal@nvidia.com> Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> 2025-07-01T19:03:41+00:00 Ellie Hermaszewska ellieh@nvidia.com 2025-07-01T19:03:41+00:00 urn:sha1:5120c1cd072548654c9ce79fa85426a5e48736c4 * Add fkYAML submodule * Generate slang-ir-inst-defs.h from slang-ir-inst-defs.yaml * generate ir-inst-defs.h * neaten things * neaten inst def parser * add rapidyaml submodule * remove fkyaml * remove fkyaml submodule * remove use of ir-inst-defs.h * format and warnings * fix wasm build * tidy * remove rapidyaml * Extend fiddle to allow custom splices in more places * Use lua to describe ir insts * fix * neaten * neaten * neaten * spelling * neaten * comment comment out assert * merge 2025-06-10T04:48:24+00:00 Mukund Keshava mkeshava@nvidia.com 2025-06-10T04:48:24+00:00 urn:sha1:d70da65a90ccd73439895a43b3958c0ea1441f35 * WiP: Add coopvec support for Optix * format code * fix minor issues * Fix review comments --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> 2025-05-16T15:30:53+00:00 Mukund Keshava mkeshava@nvidia.com 2025-05-16T15:30:53+00:00 urn:sha1:1fd7b2296d8360c245a0c732e7f842876533f92a Fixes #7127 2025-02-28T21:23:29+00:00 Darren Wihandi 65404740+fairywreath@users.noreply.github.com 2025-02-28T21:23:29+00:00 urn:sha1:efbfa7832afff7e6285713086259abda2456ed55 * update hlsl meta * update test * use slang syntax in meta file * improve meta file * fix pack clamp u8 * remove builtin packed types, use typealias instead * fix wgsl pack clamp * fix formatting --------- Co-authored-by: Yong He <yonghe@outlook.com> 2025-01-17T22:37:27+00:00 Yong He yonghe@outlook.com 2025-01-17T22:37:27+00:00 urn:sha1:fc77070fdc9bfa599e8d66b21743778de3011e53 * Refactor _Texture to constrain on texel types. * Fix tests. * Fix. * Disable glsl texture test because rhi can't run it correctly. 2025-01-08T06:26:31+00:00 Yong He yonghe@outlook.com 2025-01-08T06:26:31+00:00 urn:sha1:c43f6fa55aca23365c86c6ec1737d42be74d9d3e * Add executable test on matrix-typed vertex input. * Fix emit logic of matrix layout qualifier. * Pass fragment shader varying input by constref to allow EvaluateAttributeAtCentroid etc. to be implemented correctly. 2024-12-27T07:52:49+00:00 Darren Wihandi 65404740+fairywreath@users.noreply.github.com 2024-12-27T07:52:49+00:00 urn:sha1:7cecc518e753a90d9b638e8dd1140730ab010ca7 * Add packed bytes builtin type * fix test 2024-11-05T17:47:26+00:00 Ellie Hermaszewska ellieh@nvidia.com 2024-11-05T17:47:26+00:00 urn:sha1:b118451e301d734e3e783b3acdf871f3f6ea851c * Move switch statement bodies to their own lines * format --------- Co-authored-by: Yong He <yonghe@outlook.com>
