[PATCH] D99250: [DebugInfo] Fix the mismatching of C++ language tags and Dwarf versions.

[EsmeYi via Phabricator via cfe-commits]

Esme added inline comments.


================
Comment at: clang/lib/CodeGen/CGDebugInfo.cpp:572
       LangTag = llvm::dwarf::DW_LANG_C_plus_plus_14;
-    else if (LO.CPlusPlus11)
+    else if (LO.CPlusPlus11 && CGM.getCodeGenOpts().DwarfVersion >= 5)
       LangTag = llvm::dwarf::DW_LANG_C_plus_plus_11;

How about we just do that in this patch?
