[PATCH 0/4] MR35: vkd3d-shader/hlsl: Support complex implicit casts, complex explicit casts and complex broadcasts. (PART 2/3 v2)
Second version of !33, taking Zeb's suggestions. The refactoring allowed to encompass all remaining features of the patch series in these 4 patches. The remaining patches (PART 3/3) just contain additional tests: https://gitlab.winehq.org/fcasas/vkd3d/-/commits/complex_broadcasts_4/ -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/35

That looks like a copy-paste error; it should be "src->dimy == 1"? Kinda surprised that didn't cause any test failures...

It indeed was! And after I fixed it, some of the tests in the following patches, specifically [pixel shader fail]s involving matrices, were not passing. So this was one of the weird cases where two bugs even each other out, *sigh*. I am changing compatible_data_types() in the next version to ensure that these shaders indeed fail.

This patch removes the "broken" cases I mentioned, which is great, except that it's different from the main and stated purpose of the patch. Ideally that's something we should pull into a separate patch (earlier, or maybe later, whichever makes more sense). We also would ideally have tests for those illegal casts.

Okay, I am doing that in a separate patch earlier. Also I am moving the additional implicit cast tests forward and adding these cases specifically.

Not an issue with these patches (nor do I think it should change anything about how they're implemented), but for what it's worth, we probably should let even the invalid casts "reach" add_cast(). Or, at least, they shouldn't abort compilation; maybe we can achieve that in some other way. This is a more general problem we have—we should try to avoid aborting compilation where possible, so that multiple errors can be reported in a single pass.

Nitpicking, I think this is a bit easier to read as if (matrix_cast) { assert(dst_type->dimx <= src_type->dimx); assert(dst_type->dimy <= src_type->dimy); }
The commit message for d51c8690cfc009ea5febc600fa62a870653b967d has a newline in the subject, which is probably better avoided. If you are concerned about overlong lines, notice that you can save a few strokes rewriting as "Support implicit casts between component-wise equal types". -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/35#note_11512
