- Relevant piece is `DXILFlattenArrays.cpp` - Loads and Store Instruction visits are just for finding GetElementPtrConstantExpr and splitting them. - Allocas needed to be replaced with flattened allocas. - Global arrays were similar to allocas. Only interesting piece here is around initializers. - Most of the work went into building correct GEP chains. The approach here was a recursive strategy via `recursivelyCollectGEPs`. - All intermediary GEPs get marked for deletion and only the leaf GEPs get updated with the new index. fixes [89646](https://github.com/llvm/llvm-project/issues/89646)
