Alex Zinenko 6c5317eafa Separate translators into "from MLIR" and "to MLIR". ... Translations performed by mlir-translate only have MLIR on one end. MLIR-to-MLIR conversions (including dialect changes) should be treated as passes and run by mlir-opt. Individual translations should not care about reading or writing MLIR and should work on in-memory representation of MLIR modules instead. Split the TranslateFunction interface and the translate registry into two parts: "from MLIR" and "to MLIR". Update mlir-translate to handle both registries together by wrapping translation functions into source-to-source convresions. Remove MLIR parsing and writing from individual translations and make them operate on Modules instead. This removes the need for individual translators to include tools/mlir-translate/mlir-translate.h, which can now be safely removed. Remove mlir-to-mlir translation that only existed as a registration example and use mlir-opt instead for tests. PiperOrigin-RevId: 222398707		2019-03-29 14:06:33 -07:00
