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> 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> 2024-10-29T06:49:26+00:00 Ellie Hermaszewska ellieh@nvidia.com 2024-10-29T06:49:26+00:00 urn:sha1:f65d756bff8d4c5cbc15bd0322a2ae8e6b896a21 * format * Minor test fixes * enable checking cpp format in ci 2024-07-25T22:00:14+00:00 Yong He yonghe@outlook.com 2024-07-25T22:00:14+00:00 urn:sha1:c9d89a40775a055873adf82cfb0ee1cb6bdcb93c * Overhaul IR lowering of pointer types. * Propagate address space in IRBuilder. * Fixup. * Fix. * Fix. * Change how Ptr type is printed to text. * Fix. 2023-04-25T14:43:29+00:00 jsmall-nvidia jsmall@nvidia.com 2023-04-25T14:43:29+00:00 urn:sha1:7b7c095b37e85ca3a8f55eff1c3d9643d467b8e0 * #include an absolute path didn't work - because paths were taken to always be relative. * WIP lowerCamel Dictionary. * WIP more lowerCamel fixes for Dictionary. * Add/Remove/Clear * GetValue/Contains * Fix tabs in dictionary.
