`DEBUG_VALUE` comments are printed before an instruction, so they are not printed with `AddComment` method as other comments are, but printed using `emitRawComment` method. But currently `emitDebugValueComment` calls `emitRawComment` twice for target-index-based `DBG_VALUE`s: once in the `switch`-`case`,d77ae7f251/llvm/lib/CodeGen/AsmPrinter/AsmPrinter.cpp (L1192-L1193)
and again at the end of the method:d77ae7f251/llvm/lib/CodeGen/AsmPrinter/AsmPrinter.cpp (L1227-L1228)
This makes them printed twice. I think this happened through multiple commits modifying and refactoring this method. Reviewed By: dschuff Differential Revision: https://reviews.llvm.org/D139579
