Kenneth Russell e196bc85 2020-01-17T13:11:20 Add driver bug workaround for rewriting row major matrices. Joint work with syoussefi@, who wrote the RewriteRowMajorMatrices pass, and revised it for this CL to not rely on the NameNamelessUniformBuffers pass - which was breaking it on the GL backend. Hook up previously written RewriteRowMajorMatrices transformation, and enable on all GPU types on macOS. It is needed at least for AMD and Intel GPUs. Add a new test which verifies the behavior of dynamically-indexed arrays of row-major matrices.

Shahbaz Youssefi 86d9c93a 2019-12-16T16:07:04 Use TSpan for TType's array sizes Until C++20, std::vector doesn't have a constexpr constructor, which means TType cannot use a `TVector` for `mArraySizes` if an arrayed type needs to be created constexpr. This is needed for the upcoming textureGatherOffsets implementation. A new TSpan class is introduced, based on std::span (from C++20) that holds the pointer/size allocated from a TVector without owning it. Since TVector's allocation are made from a pool, the allocated memory will live beyond the vector's destruction. `TType::mArraySizes` is changed to this type. This change will allow a new constexpr constructor to be added to TType that takes a TSpan as array directly, a value which is constexpr initialized from a static array (instead of TVector).

Shahbaz Youssefi db3e5183 2019-11-14T13:47:55 Vulkan: Fix col-major transformation of unsized arrays If the row-major expression that was being transformed was in the form: arr.length() where `arr` is an SSBO unsized array, the translator transformation was attempting to transpose the `arr` expression, which is both wrong and impossible. Note that length() is removed through a prior transformation except for this particular case. This change recognizes this usage and supports it by keeping the expression as is (as the length() would be identical pre or post transformation).
