2024-11-21Refresh of disabled WGPU tests (#5614)Anders Leino
Some tests are now passing and are enabled. Other tests are still failing, but are given comments categorizing the failures. Tests in the 'Not supported in WGSL' category are also removed from the expected failures list. (Though they are still kept disabled for WebGPU, of course.) This closes #5519.

2024-08-12Warn when inout parameter is never written (#4777)venkataram-nv
Addresses #4698 as one approach to diagnose the potential problem. Emit warnings when a user marks a parameter as `inout` but never writes to it in the function. A new intrinsic function `unmodified(out T)` has been added to explicitly indicate that an `inout` variable will not be modified in the function. This is only one way to address the specific validation error in #4698. In general it seems that DXC does some more extensive checks on actual struct fields (as opposed to observing arbitrary struct writes), so that will be the next step.

* 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>

2024-07-23Simplify `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.

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
