[Bug fortran/43954] New: gfortran-4.4 does not support -Wp, -MD for *.F (4.3 -> 4.4 regression, needed for auto-dependencies)

[Bug fortran/43954] New: gfortran-4.4 does not support -Wp, -MD for *.F (4.3 -> 4.4 regression, needed for auto-dependencies)

[kirr at landau dot phys dot spbu dot ru]

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]

    $ gfortran-4.3 -v -Wp,-MD,test.d test.F
    Driving: gfortran-4.3 -v -Wp,-MD,test.d test.F -lgfortranbegin -lgfortran

    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

If real life allows, I'll give it another try for 4.6 - started twice already
but there are quite a few options to handle. However, if you feel like it, dig
in. Help is always welcome :)

Closing as dupe of PR31588.

Daniel, thanks for reply.

As I see it, yes, PR31588 would be handy enhancement, but this bug is different
-- it's a _regression_ -- it used to work in 4.3 and stopped in 4.4.

And when I say "it used to work" I don't mean generating dependencies for
f90/f95 sources (PR31588 mentions e.g. USE), but only generating dependencies
from plain preprocessor.

Please, let's not break what used to work.
Is it ok reopen?


P.S. I'd like to help as time permits, but hacking on GCC codebase is out of my
skills at present. If that would help I'm able and will be glad to try patches
and do other testing as well.

Sorry and thanks,
Kirill

What you ask for is "just" a subset of PR31588. If that gets fixed, your
request will be fixed as well.

Feel free to re-open if you believe that it would be worth to fix the subset
first.

I'll keep that in mind :)

Yes, it's a subset of PR31588. 

But as you wrote PR31588 is going to be (maybe) fixed for 4.6, while I
believe regressions in general and this one in particular should be
better handled with higher priority and fixes should go to maintanance
branches.

Also, my impression is that PR31588 is more work than fixing "just" this
subset. That's why I'm reopening it.


Sorry if I ask for too much, especially when I can't help with code...

What you apparently fail to understand is that gfortran is written
and maintained by a small group of volunteers.  If none of these
volunteers use this feature and if none of volunteers have the 
time to work on it, it won't get fixed anytime soon.  So, if this
is so dear to your heart, pull up your sleeves and start trying to
fix the problem.

In the meantime, just call cpp directly.

REOPEN

Daniel, thanks for working on this.

Because dropping support for -MD was initially spot as 4.3 -> 4.4 regression,
and you committed the fix to 4.6 only, I think it would be good to apply your
patch to 4.4 and 4.5 branches as well.

I've backported it on top of today's gcc-4_4-branch and gcc-4_5-branch. Tested
on i686-pc-linux-gnu OK for 4.4 and "OK for check-fortran" for 4.5 (*).

Two patches for 4.4 & 4.5 will be next attached.

Please apply and thanks,
Kirill


(*) as of today, gcc-4_5-branch does not pass all tests on i686-pc-linux-gnu.
Look e.g. here http://gcc.gnu.org/ml/gcc-testresults/2010-06/

Could someone please suggest me what I'm maybe doing wrong?

Because I posted backported patches twice (first time on the mailing list) and
there is always silence on gcc side...

And as it is now, -4.4 and -4.5 are left in regressed state compared to -4.3,
and the fix is only applied to -4.6 .

Thanks,
Kirill


P.S. and as to the workaround described in comment5 - it does not fully
qualify, becase for example calling cpp directly does not define predefined
__GFORTRAN__, and I'm sure there are other corner-case when cpp'ing by hand
differs from preprocessing from-under gfortran.

Nothing wrong. Just ping the patch from time to time ;-). 
I've set the target milestone to 4.3.6, so that it may get more attention.

I see, thanks.

Thanks again. But why 4.3? It's 4.4 and 4.5 which need fixing. 4.3 is
ok. Am I misunderstanding something?


Thanks,
Kirill

I have the patch for backport to 4.5 applied to my local 4.5 branch and I am
regression testing now.

Thanks a lot!

Only if you could please also apply the -4.4 version. *Please*

The rationale for this is that 4.4 will be the default compiler in the
next upcoming Debian stable.


Thanks,
