Alex Zinenko 881dc34f73 [mlir] replace llvm.mlir.cast with unrealized_conversion_cast ... The dialect-specific cast between builtin (ex-standard) types and LLVM dialect types was introduced long time before built-in support for unrealized_conversion_cast. It has a similar purpose, but is restricted to compatible builtin and LLVM dialect types, which may hamper progressive lowering and composition with types from other dialects. Replace llvm.mlir.cast with unrealized_conversion_cast, and drop the operation that became unnecessary. Also make unrealized_conversion_cast legal by default in LLVMConversionTarget as the majority of convesions using it are partial conversions that actually want the casts to persist in the IR. The standard-to-llvm conversion, which is still expected to run last, cleans up the remaining casts standard-to-llvm conversion, which is still expected to run last, cleans up the remaining casts Reviewed By: nicolasvasilache Differential Revision: https://reviews.llvm.org/D105880		2021-07-16 15:14:09 +02:00
