That's true, if defined in a header, we'll emit a `DW_TAG_variable` for the constant in each compile unit the header is included in. GCC does do the right thing and only emit the definition DIE in a single CU. We should probably do the same. Though not sure at which level. Possibly the DWARF linker? https://github.com/llvm/llvm-project/pull/70639 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
