Warn when inout parameter is never written (#4777)

2024-08-12T21:18:02+00:00

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.

Fix bug with uninititialized warnings in nested scopes (#4677)

2024-07-18T18:13:26+00:00

Previously the warning system ignores undefined variables in nested scopes (blocks in IR).

Initial sizeof/alignof implementation. (#2954)

2023-07-05T17:23:14+00:00

* Initial sizeof implementation. * Small macro improvement. * Fix some typos. * Refactor NaturalSize. Add more sizeof tests. * Use _makeParseExpr to add sizeof support. * Add size-of.slang diagnostic result. * Fix typo in folding with macro change. * Add a sizeof test of This. * Some more NaturalSize coverage. * Simple alignof support. * Testing for alignof. * Added 8 bit enum to check enums values are correctly sized. * Add alignof to completion. * Lower sizeof/alignof to IR. sizeof/alignof IR pass. Tests for simple generic scenarios. * Make append handle invalid properly. Improve comments. --------- Co-authored-by: Theresa Foley <10618364+tangent-vector@users.noreply.github.com>
