From: "fxcoudert at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug fortran/26682] gfortran fails with -fwhole-program optimization Date: Mon, 01 Oct 2007 10:58:00 -0000 [thread overview] Message-ID: <20071001105825.27096.qmail@sourceware.org> (raw) In-Reply-To: <bug-26682-12362@http.gcc.gnu.org/bugzilla/> ------- Comment #2 from fxcoudert at gcc dot gnu dot org 2007-10-01 10:58 ------- There are three different issues: 1. -fwhole-program should be documented as not working for the Fortran programs. 2. The Fortran main program (MAIN__) needs to be kept by the -fwhole-program optimization; I think one way of achieving this is to mark it as "externally_visible", but I might be wrong (I've already been wrong on that issue,!). 3. We need to generate a correct call graph for Fortran code, either by emitting one single decl per function, or by making the cgraph calculation aware of this possible situation. I'll try to tackle 1 and 2, but 3 needs to wait until 4.3 is branched. -- fxcoudert at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |fxcoudert at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED Keywords| |documentation Last reconfirmed|2007-07-13 15:47:54 |2007-10-01 10:58:25 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26682
