Description Siddhesh Poyarekar 2011-02-04 12:31:51 UTC 
Created attachment 476992 [details]
Backport from r162990 upstream

Description of problem:

gfortran no longer recognizes the -M* options in gcc-4.4. This is a regression in gcc-4.4 caused when gfortran moved from cc1 to libcpp for its external preprocessor. The feature works correctly in RHEL-5. The bug has been documented and fixed upstream:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43954

How Reproducible:

Always

Steps to Reproduce:

root@gncc mtest # cat mtest.F
#include "mtest.h"
        x(1) = 2
        print 10, x(1)
 10     format(' Hello World, x(1) =', i5)
        end

root@gncc mtest # cat mtest.h
        integer x(10)

root@gncc mtest # gcc -M mtest.F

Actual Result:

root@gncc mtest # gcc -M mtest.F
f951: warning: command line option "-M" is valid for C/C++/Java/ObjC/ObjC++ but not for Fortran

Expected Result:

root@gncc mtest # gcc -M mtest.F
mtest.o: mtest.F mtest.h

This has been committed to upstream 4.4 branch on
Date: Sun Aug  8 01:59:15 2010
therefore it is in RHEL6.1 gcc-4.4.5-5.el6, which is currently based on
20110117 snapshot.
