From: "gprocida at google dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/111788] New: g++ DWARF for void foo(...) missing unspecified parameters DIE Date: Thu, 12 Oct 2023 16:00:17 +0000 [thread overview] Message-ID: <bug-111788-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111788 Bug ID: 111788 Summary: g++ DWARF for void foo(...) missing unspecified parameters DIE Product: gcc Version: 13.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: gprocida at google dot com Target Milestone: --- I'm putting this in component c++ rather than debug, because the debug information is correct for C compilation. FWIW, clang++-15 does emit DW_TAG_unspecified_parameters. $ cat v.c int foo1(int x, int y, ...) { return x + y; } int foo2(int x, ...) { return x; } int foo3(...) { return 0; } $ gcc -Wall -Wextra -g -c v.c v.o # DWARF for foo3 includes DW_TAG_unspecified_parameters $ g++ -Wall -Wextra -g -c v.c v.o # DWARF for foo3 does NOT include DW_TAG_unspecified_parameters $ g++ -v Using built-in specs.
