* Adjust License.txt file to use the LLVM licenseMehdi Amini2019-12-232-26/+8

* Fix minor spelling tweaks (NFC)Kazuaki Ishizaki2019-10-201-1/+1
| | | | | | Closes tensorflow/mlir#175 PiperOrigin-RevId: 275726876
* NFC: Remove trivial builder get methods.River Riddle2019-10-171-1/+1
| | | | | | These don't add any value, and some are even more restrictive than the respective static 'get' method. PiperOrigin-RevId: 275391240
* Handle OpMemberName instruction in SPIR-V deserializer.Mahesh Ravishankar2019-09-231-4/+72
| | | | | | | | | | Sdd support in deserializer for OpMemberName instruction. For now the name is just processed and not associated with the spirv::StructType being built. That needs an enhancement to spirv::StructTypes itself. Add tests to check for errors reported during deserialization with some refactoring to common out some utility functions.

* Refactor DiagnosticEngine to support multiple registered diagnostic handlers.River Riddle2019-09-231-1/+1
| | | | | | | | | | | | This fixes a problem with current save-restore pattern of diagnostics handlers, as there may be a thread race between when the previous handler is destroyed. For example, this occurs when using multiple ParallelDiagnosticHandlers asynchronously: Handler A Handler B | - LifeTime - | Restore A here. Handler C | --- LifeTime ---| Restore B after it has been destroyed. The new design allows for multiple handlers to be registered in a stack like fashion. Handlers can return success() to signal that they have fully processed a diagnostic, or failure to propagate otherwise. PiperOrigin-RevId: 270720625
* NFC: Pass OperationState by reference instead of by pointer.River Riddle2019-09-201-1/+1
| | | | | | MLIR follows the LLVM convention of passing by reference instead of by pointer. PiperOrigin-RevId: 270396945
* [spirv] Fix the entry block to start with OpLabelLei Zhang2019-08-271-5/+29
| | | | | | | | Each basic block in SPIR-V must start with an OpLabel instruction. We don't support control flow yet, so this CL just makes sure that the entry block follows this rule and is valid. PiperOrigin-RevId: 265718841
* [spirv] Add Block decoration for spv.struct.Denis Khalikov2019-08-272-0/+127
| | | | | | | | Add Block decoration for top-level spv.struct. Closes tensorflow/mlir#102 PiperOrigin-RevId: 265716241
* [spirv] Add basic infrastructure for negative deserializer testsLei Zhang2019-07-302-0/+211
We are relying on serializer to construct positive cases to drive the test for deserializer. This leaves negative cases untested. This CL adds a basic test fixture for covering the negative corner cases to enforce a more robust deserializer. Refactored common SPIR-V building methods out of serializer to share it with the deserialization test. PiperOrigin-RevId: 260742733
