For instance, are rhs expressions such as `ANISOTROPIC + 1` marked as a of the _constant load_ type in the effects metadata? After applying the passes we have to check the type of the last instruction of the block (or args[0], in case ths is not a complex initializer with braces) which represents the whole expression, and see if it is HLSL_IR_CONSTANT, HLSL_IR_INDEX (in which case we have to check if the index part is constant) or HLSL_IR_EXPR. We should also probably introduce a pass exclusive to fx.c to lower known HLSL_IR_UNDECLARED_LOAD into constants, so constant folding (if required) can work. I don't know yet how complex initializers with braces work in this case, if at all, but they parse. -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/739#note_65852

It's not a load, since it's not coming from a variable. I would rather say something like "effect constant" or "stateblock constant". -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/739#note_65850

There's a lot of tests for valid array usage, but not invalid array usage. What if the count is mismatched? Can an array of size 1 take interior braces? Can a non-array take interior braces? -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/739#note_65847

Or alternatively use "arrays" and add an explicit check for count > 1. Is C_INTEGER correct here, or should we allow compile-time constants? -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/739#note_65846
