Kazu Hirata	70c73d1b72	[mlir] Use std::nullopt instead of None in comments (NFC) ... This is part of an effort to migrate from llvm::Optional to std::optional: https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716	2022-12-04 17:23:50 -08:00
Thomas Raoux	f8fafe99a4	[mlir] Add unsigned version of index_cast ... This is required to be able to cast integer type to a potential larger index using zero-extend cast. There is a larger change under discussion to move index ops in a separate dialect: https://discourse.llvm.org/t/rfc-index-dialect/65540/ Based on timing of this work this patch can be included as part of this effort but as a short term solution we may want to add this op to arithmetic dialect for now in order to fill the gap.
