From: "p dot w dot draper at durham dot ac dot uk" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug fortran/23060] New: %VAL construct not implemented Date: Mon, 25 Jul 2005 15:28:00 -0000 [thread overview] Message-ID: <20050725152615.23060.p.w.draper@durham.ac.uk> (raw) The %VAL construct is used for passing arguments by value, rather than the usual by reference or descriptor. It is vital for interoperability with other languages such as C. This feature is available in g77: http://gcc.gnu.org/onlinedocs/gcc-3.4.4/g77/_0025VAL_0028_0029.html#_0025VAL_0028_0029 My interest in this feature comes from the world of astronomy where we have a large legacy code base (~1 Million SLOC) written in Fortran 77, (see http://cvsweb.starlink.ac.uk) where this feature is used for efficiently accessing large data arrays using mmap, complex data structures, and for accessing dynamic memory. -- Summary: %VAL construct not implemented Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: p dot w dot draper at durham dot ac dot uk CC: gcc-bugs at gcc dot gnu dot org GCC target triplet: i386-redhat-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23060
