<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-lldb Author: Michael Buch (Michael137) <details> <summary>Changes</summary> Depends on: * https://github.com/llvm/llvm-project/pull/170132 Clang gained the `-gtemplate-alias` not too long ago, which emits C++ alias templates as `DW_TAG_template_alias` (instead of `DW_TAG_typedef`). The main difference is that `DW_TAG_template_alias` has `DW_TAG_template_XXX` children. The flag was not enabled by default because consumers (mainly LLDB) didn't know how to handle it. This patch adds rudimentary support for debugging with `DW_TAG_template_alias`. This patch simply creates the same kind of `TypedefDecl` as we do for `DW_TAG_typedef`. The more complete solution would be to create a `TypeAliasTemplateDecl` and associated `TypeAliasDecl`. But that would require DWARF to carry generic template information, but currently each `DW_TAG_template_alias` represents a concrete instantiation. We could probably hack up some working AST representation that includes the template parameters, but I currently don't see a compelling reason to. All we need is the `DW_AT_name` and the `DW_AT_type` that the typedef refers to. One compelling reason to support `DW_TAG_template_alias` is that with `-gsimple-template-names`, `DW_TAG_typedef`s for alias templates have their template parameters stripped from the `DW_AT_name`. With just a plain `DW_TAG_typedef`, LLDB has no way to reconstruct the full `DW_AT_name`. But since `DW_TAG_template_alias` can carry template parameter children, LLDB can reconstitute the name by concatenating the `DW_AT_name`s of the child tags. --- Patch is 24.25 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/170135.diff 2 Files Affected: - (modified) lldb/source/Plugins/SymbolFile/DWARF/DWARFASTParserClang.cpp (+3-1) - (modified) lldb/unittests/SymbolFile/DWARF/DWARFASTParserClangTests.cpp (+211-182) ``````````diff diff --git a/lldb/source/Plugins/SymbolFile/DWARF/DWARFASTParserClang.cpp b/lldb/source/Plugins/SymbolFile/DWARF/DWARFASTParserClang.cpp index 36aa49ac3de95..3d556aea7b183 100644 --- a/lldb/source/Plugins/SymbolFile/DWARF/DWARFASTParserClang.cpp +++ b/lldb/source/Plugins/SymbolFile/DWARF/DWARFASTParserClang.cpp @@ -623,6 +623,7 @@ TypeSP DWARFASTParserClang::ParseTypeFromDWARF(const SymbolContext &sc, switch (tag) { case DW_TAG_typedef: + case DW_TAG_template_alias: case DW_TAG_base_type: case DW_TAG_pointer_type: case DW_TAG_reference_type: @@ -748,7 +749,7 @@ DWARFASTParserClang::ParseTypeModifier(const SymbolContext &sc, TypeSP type_sp; CompilerType clang_type; - if (tag == DW_TAG_typedef) { + if (tag == DW_TAG_typedef || tag == DW_TAG_template_alias) { // DeclContext will be populated when the clang type is materialized in // Type::ResolveCompilerType.
