--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-01-27 08:31:56 UTC ---
In the compiler, the file name is handled in cpp.c via
gfc_cpp_option.output_filename -- but that part looks OK.
It seems to be a driver problem as the driver passes:
.../x86_64-unknown-linux-gnu/4.6.0/f951 ... -o test.d ... -o /tmp/cckDPYJ6.s
Thus, either a rule in lang-specs.h is wrong/missing or the problem is in
gfortranspec.c.
I think something like: %{!o*:-o %b.s} is missing and %b.s allways is
implicitly used.
Maybe %(cpp_unique_options) should be used? Currently, lang-specs.h contains
the following:
/* Identical to gcc.c (cpp_options), but omitting %(cpp_unique_options)
and -fpch-preprocess on -save-temps. */
#define CPP_ONLY_OPTIONS "%1 %{m*} %{f*} %{g*:%{!g0:%{g*} \
%{!fno-working-directory:-fworking-directory}}} \
%{std*&ansi&trigraphs} %{W*&pedantic*} %{w} \
%{O*} %{undef}"
The %b.s seems to be defined in gcc.c's cc1_options.

Missed some parts. Better patch - still completely untested (not even built). A
shorter version would be "%{!E:%{!M*:", which is also completely untested.

Can't you do
"%{E|M|MM|MT|MQ|MD|MMD:;:" F951_OPTIONS "}"
instead?

I have tested variant suggested in #comment 4 and those in #comment 5. Both
are fixing the ICE. The file test.d (as used as crash example) will be created
empty.

Good idea - and looks cleaner. Except (my bug) that -MD and -MMD do not imply
"-E". Thus, those shouldn't appear in that list.
Additionally, with -M the output goes - according to Kai (thanks for testing!)
- still to stdout. I think the "if (gfc_cpp_preprocess_only ())" in
fortran/cpp.c's gfc_cpp_init_0 needs to be modified.
