From: "burnus at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug fortran/111783] New: 'exit' intrinsic should be marked as Date: Thu, 12 Oct 2023 11:59:06 +0000 [thread overview] Message-ID: <bug-111783-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111783 Bug ID: 111783 Summary: 'exit' intrinsic should be marked as Product: gcc Version: 14.0 Status: UNCONFIRMED Keywords: missed-optimization Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: burnus at gcc dot gnu.org Target Milestone: --- Compiling testsuite/gfortran.dg/team_number_1.f90 with -O3 produces the following optimized dump: _gfortran_exit_i4 (0); _gfortran_exit_i4 (0); _gfortran_stop_numeric (2, 0); } The last three statements could be removed as the 'EXIT' intrinsic subroutine is known not to return. Thus, we should set ATTR_NORETURN_NOTHROW_LIST (cf. fortran/f95-lang.cc). There are probably more, at least the ABORT intrinsic subroutine and the functions associated with STOP / ERROR STOP like _gfortran_stop_numeric.
