Index type is an integer type of target-specific bitwidth present in many MLIR operations (loops, memory accesses). Converting values of this type to fixed-size integers has always been problematic. Introduce a data layout entry to specify the bitwidth of `index` in a given layout scope, defaulting to 64 bits, which is a commonly used assumption, e.g., in constants. Port builtin-to-LLVM type conversion to use this data layout entry when converting `index` type and untie it from pointer size. This is particularly relevant for GPU targets. Keep a possibility to forcibly override the index type in lowerings. Depends On D98525 Reviewed By: herhut Differential Revision: https://reviews.llvm.org/D98937 |
