[Bug fortran/32289] New: mips version of gfortran produces internal compiler error

When I compile the following function using the mips version of gfortran I get
the message:

q.f90:3: internal compiler error: in gfc_conv_variable, at
fortran/trans-expr.c:381

Michael,

Can you upgrade to either gfortran 4.2 or gfortran 4.3 (aka trunk)?
The code compiles for me with both of these compilers.  As a side
note, I use gfortran 4.2 asmy everyday compiler, and I think you'll
be much happier with it.

I run Debian Linux 4.0 on my SGI box. When I type "apt-get source gcc-4.1", it
downloads a version of gcc 4.1.2 that appears to be extensively hacked up. This
version produced the referenced error. Could you tell me briefly where you get
the source code, and what procedure you use to build the executable? Thank you
very much.

Michael, I build gfortran from source, which for the mips architecture 
is probably your only option.  You'll need subversion.  To get the bleeding
edge, do

cd tmp
svn checkout svn://gcc.gnu.org/svn/gcc/trunk
mkdir obj
cd obj
../trunk/configure --prefix=<path_to_install_to> --enable-languages=c,gfortran
make bootstrap
make install

You can also grab the gcc-4.2 tarball from ftp.gnu.org (or a mirror).

This works with 4.3.0 20070604 on mips.

I can reproduce this with current 4.1 from SVN, but not with 4.2 from SVN.

When you build gcc and gfortran on your mips box, do you specify your system
type as "mips-unknown-linux-gnu" or as "mips64-unknown-linux-gnu"?

mips-linux-gnu, as the Debian package does.  Why?

When I run the configure script on an SGI Indy under Debian 4.0, it sets the
system type to mips64-unknown-linux-gnu, and sets the ABI to N32.

When I run the configure script under Debian 3.1, it sets the system type to
mips-unknown-linux-gnu, and sets the ABI to 32.

Which ABI do you use?

O32, just like Debian.  Note that 4.0 also uses O32, although the kernel is
64-bit, so that might explain why it's configuring mips64 for you.

I don't see the point of these questions though.  After all, I confirmed your
bug with gcc 4.1, and also that it's fixed in 4.2 and 4.3.  So the remaining
question is whether this will be fixed in 4.1 (which I doubt).

No, this will not be fixed. Thanks for the bugreport anyway, Michael, and I
hope you can get your GCC-4.3 build working. (If you need technical help doing
so, you can ask on the gcc-help@gcc.gnu.org mailing-list.)

Note that gcc-4.2 exists on MIPS in Debian testing and 4.3 in the form
of the gcc-snapshot package in Debian unstable.
