This caused asserts: llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp:2331: virtual void llvm::DwarfDebug::endFunctionImpl(const llvm::MachineFunction *): Assertion `LScopes.getAbstractScopesList().size() == NumAbstractSubprograms && "getOrCreateAbstractScope() inserted an abstract subprogram scope"' failed. See comment on the code review for reproducer. > RFC https://discourse.llvm.org/t/rfc-dwarfdebug-fix-and-improve-handling-imported-entities-types-and-static-local-in-subprogram-and-lexical-block-scopes/68544 > > Similar to imported declarations, the patch tracks function-local types in > DISubprogram's 'retainedNodes' field. DwarfDebug is adjusted in accordance with > the aforementioned metadata change and provided a support of function-local > types scoped within a lexical block. > > The patch assumes that DICompileUnit's 'enums field' no longer tracks local > types and DwarfDebug would assert if any locally-scoped types get placed there. > > Reviewed By: jmmartinez > > Differential Revision: https://reviews.llvm.org/D144006 This reverts commit f8aab289b5549086062588fba627b0e4d3a5ab15.
