[Lldb-commits] [lldb] [lldb][Fortran] Add Fortran plugin foundational files (PR #210377)

Fri Jul 17 10:03:22 PDT 2026
https://github.com/Iasonaskrpr created https://github.com/llvm/llvm-project/pull/210377
Depends on #207764.
This PR introduces the foundational skeleton files and infrastructure required to register Fortran as a supported language plugin in LLDB. At this stage, the `TypeSystemFortran` and `DWARFASTParserFortran` implementations return null/stub implementations.
### Changes
- **Language Plugin**: Adds the baseline `LanguageFortran` plugin to recognize Fortran programs.
- **TypeSystem**: Adds the `TypeSystemFortran` skeleton class and handles its initial registration.
- **DWARF Parser**: Adds the `DWARFASTParserFortran` boilerplate required by the type system.
Part of the Add Fortran support to LLDB GSoC 2026 project.
