The last uses of the F77_FOR_TARGET via passing f77 to GDB's compile procedure were removed in this commit commit 0ecee54cfd04a60e7ca61ae07c72b20e21390257 Author: Tom Tromey <tromey@redhat.com> Date: Wed Jun 29 17:50:47 2011 +0000 over 10 years ago. The last .f files in the testsuite by now are all being compiled by passing 'f90' to the GDB compile, thus only actually using F90_FOR_TARGET (array-element.f, block-data.f, subarray.f). Gfortran in this case is backwards compatible with most f77 code as claimed on gcc.gnu.org/fortran. The reason we'd like to get rid of this now is, that we'll be implementing a Fortran compiler identification mechanism, similar to the C/Cpp existing ones. It would be using the Fortran preprocessor macro defines to identify the Fortran compiler version at hand. We found it inconsequent to only implement this for f90 but, on the other hand, f77 seems deprecated. So, with this commit we remove the remaining lines for its support.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
