Jim Blandy ed3006ccc6 [naga spv-out] Spill arrays and matrices for runtime indexing. ... Improve handling of `Access` expressions whose base is an array or matrix (not a pointer to such), and whose index is not known at compile time. SPIR-V does not have instructions that can do this directly, so spill such values to temporary variables, and perform the accesses using `OpAccessChain` instructions applied to the temporaries. When performing chains of accesses like `a[i].x[j]`, do not reify intermediate values; generate a single `OpAccessChain` for the entire thing. Remove special cases for arrays; the same code now handles arrays and matrices. Update validation to permit dynamic indexing of matrices. For details, see the comments on the new tracking structures in `naga:🔙:spv::Function`. Add snapshot test `index-by-value.wgsl`. Fixes #6358. Fixes #4337. Alternative to #6362.		2024-10-11 08:27:15 -07:00
