Package: gfortran-4.4
Version: 4.4.2-9
Severity: normal
Hello,
Like with gcc and g++, for compiling .F sources with gfortran, I
thankfully use automatic dependencies generator built into gcc's cpp.
E.g. for
$ cat test.F
#include "test.h"
program test
print *,'Hello World!'
print *,ZZZ
end
$ cat test.h
#define ZZZ 'Hello up there qqq!'
gfortran-4.3 correctly generates .d file for make:
$ gfortran-4.3 -Wp,-MD,test.d test.F
$ cat test.d
test.o: test.F test.h
but gfortran-4.4 fails:
$ rm test.d
$ gfortran-4.4 -Wp,-MD,test.d test.F
f951: warning: command line option "-MD" is valid for C/C++/ObjC/ObjC++ but
not for Fortran
$ cat test.d
cat: test.d: No such file or directory
I think gfortran-4.4 behaviour is incorrect, since .F files (contrast
with .f) by definition should be passed through preprocessor, and if so,
why dropping automatic dependencies generation which worked in 4.3?
I guess the regression is somehow related to the fact, that starting from
gcc-4.4, "GNU Fortran now employs libcpp directly instead of
using cc1 as an external preprocessor." [1]

f951: warning: command line option "-MD" is valid for C/C++/ObjC/ObjC++ but
not for Fortran
And since -MD was declared to be C/C++/ObjC/ObjC++ only option for ages
(at least since 2003-06-01 d821d2 in gcc.git), now for 4.4. it does not
work. It worked for 4.3 because there `cc1 -E` is explicitly called as
separate step... And for 4.4. calling cc1 explicitly works too
$ /usr/lib/gcc/i486-linux-gnu/4.4.3/cc1 -E -D_LANGUAGE_FORTRAN -quiet -v
-MD test.d test.F -o test.f
$ cat test.d
test.o: test.F test.h
but is of no help because cc1 is internal.
--------
Clearly this is functional regression to me. If possible please fix.
Thanks beforehand,
Kirill
