2025-05-09	[Flang] Add missing dependency to AddDebugInfo pass (#139099)	Sergio Afonso
	The `AddDebugInfo` pass currently has a dependency on the `DLTI` MLIR dialect caused by a call to the `fir::support::getOrSetMLIRDataLayout()` utility function. This dependency is not captured in the pass definition. This patch adds the dependency and simplifies several unit tests that had to explicitly use the `DLTI` dialect to prevent the missing dependency from causing compiler failures.
2024-09-11	[flang][debug] Handle 'used' module. (#107626)	Abid Qadeer
	As described in #98883, we have to qualify a module variable name in debugger to get its value. This PR tries to remove this limitation. LLVM provides `DIImportedEntity` to handle such cases but the PR is made more complicated due to the following 2 issues. 1. The MLIR attributes are readonly and we have a circular dependency here. This has to be handled using the recursive interface provided by the MLIR. This requires us to first create a place holder `DISubprogramAttr` which is used in creating `DIImportedEntityAttr`. Later another `DISubprogramAttr` is created which replaces the place holder. 2. The flang IR does not provide any information about the 'used' module so this has to be extracted by doing a pass over the `DeclareOp` in the function. This presents certain limitation as 'only' and module variable renaming may not be handled properly. Due to the change in `DISubprogramAttr`, some tests also needed to be adjusted. Fixes #98883.
