[mlir][NFC] Update textual references of func to func.func in IR/Interface tests The special case parsing of func operations is being removed. | 4 年前 | |
DestinationPassingStyle: allow additional non-tensor results Also some simplifications: * outputBufferOperands was unused. * The condition that the number of operands equals the number of inputs plus the number of inits seemed vacuously true (?).

Introduce MLIR Op Properties This new features enabled to dedicate custom storage inline within operations. This storage can be used as an alternative to attributes to store data that is specific to an operation. Attribute can also be stored inside the properties storage if desired, but any kind of data can be present as well. This offers a way to store and mutate data without uniquing in the Context like Attribute. See the OpPropertiesTest.cpp for an example where a struct with a std::vector<> is attached to an operation and mutated in-place: struct TestProperties { int a = -1; float b = -1.; std::vector<int64_t> array = {-33}; }; More complex scheme (including reference-counting) are also possible. The only constraint to enable storing a C++ object as "properties" on an operation is to implement three functions: - convert from the candidate object to an Attribute - convert from the Attribute to the candidate object - hash the object Optional the parsing and printing can also be customized with 2 extra functions. A new options is introduced to ODS to allow dialects to specify: let usePropertiesForAttributes = 1; When set to true, the inherent attributes for all the ops in this dialect will be using properties instead of being stored alongside discardable attributes. The TestDialect showcases this feature. Another change is that we introduce new APIs on the Operation class to access separately the inherent attributes from the discardable ones. We envision deprecating and removing the getAttr(), getAttrsDictionary(), and other similar method which don't make the distinction explicit, leading to an entirely separate namespace for discardable attributes.

[mlir] Add function for checking if a block is inside a loop This function returns whether a block is nested inside of a loop. There can be three kinds of loop: 1) The block is nested inside of a LoopLikeOpInterface 2) The block is nested inside another block which is in a loop 3) There is a cycle in the control flow graph This will be useful for Flang's stack arrays pass, which moves array allocations from the heap to the stack. Special handling is needed when allocations occur inside of loops to ensure additional stack space is not allocated on each loop iteration.
