[drab at kepler dot fjfi dot cvut dot cz]

When compiling todays (20071210) SVN snapshot of gcc using:

../gcc-SVN-20071210/configure --build=x86_64-pc-linux-gnu --with-arch=athlon64
--enable-fixed-point
make

I the compilation fails with:

Confirmed with today' r131705.  The --with-arch option seems to have no
involvement here.

Hello

I got the same problems using the 4.3.0 release as well as with the current 4.4
snapshot (20080307).

Is there any workaround? Or any version where --enable-fixed-point actually
works? I tried 4.2.3, which compiled fine, but the resulting compiler doesn't
support the extensions...

------- Comment #3 from bernard at brenda-arkle dot me dot uk  2008-10-17 21:08 -------
I've seen this with 4.3.1 and 4.3.2 official releases with (as it happens)
athlon-64 again (but 32-bit Linux).  But then I also saw it with 4.3.1
on a pure Pentium4 system, so I don't think it's really 64-bit specific.
I've *never* built successfully with --enable-fixed-point .

fixed point support is only currently supported for the MIPS target.

(In reply to Andrew Pinski from comment #5)
> fixed point support is only currently supported for the MIPS target.

So could the configure script error out earlier, then, if it is passed
--enable-fixed-point for a target other than MIPS?
