Could you submit a preprocessed testcase?
Many of us do not have m68k hardware that can be used for bootstrap.

Thanks,

m68k is not a primary or secondary platform.

This is a very common error on m68k.  We got another bug report, see
http://bugs.debian.org/359281, which says:

> torcs, grace, and rscheme all fail with variations on the theme of
> track.s: Assembler messages:
> track.s:10716: Error: value out of range

> This bug appears in at least gcc-4.0 4.0.2-3 - 4.0.2-10.
> Works fine with latest binutils and gcc-3.3.

> torcs (g++) and grace (gcc) can be made to compile with -O1 for
> both 4.1 and 4.0.

> rscheme works with gcc-4.0 -O1 and gcc-4.1 -O2 (in other words,
> it seems to be fixed in 4.1 although the error seems the same).

> None of these look easy to reduce.

> Please let me know what else I can provide.

I have been running some testcases through delta and while they got smaller,
they're still fairly large.  However, I'll attach them and hope that someone
can make sense of what's going on here.

------- Comment #6 from tbm at cyrius dot com  2006-06-20 22:08 -------
I can provide more testcases on request but I think the general pattern is
clear from these two:

23:00 < apinski> tbm: what is on the line which the assembler is complaining
about
23:01 < tbm> fbnlt .L297
23:03 < apinski> the only thing I can think of is the distance is just too long
23:05 < apinski> tbm: so reducing the testcase is not going to help as you are
just going to end up with a big testcase no matter what

BTW, going from -O2 to -O1 makes both of these testcases compile.

This test case is probably also interesting because it shows a slightly
different error:

[schwab at suse dot de]

------- Comment #8 from schwab at suse dot de  2006-06-20 22:43 -------
The problem with the attached testcases is that gcc is using fbCC instead of
fjCC.  The former set of insns is interpreted by GAS as fixed length branches
with 16 bit offset, whereas the latter is handled as variable sized branch with
either 16 bit or 32 bit offset.  But the bootstrap error is a different
problem, since a floating point branch does not have a 8 bit field.  Please
move the test cases to a new bug, and instead attach a testcase for the
original problem.

I don't see that bootstrap error anymore so I suggest this PR to be retitled
for the other testcases.  Or is the 3rd testcase an example of the original
problem?
If so, let's keep that and I'll move the first two testcases to another PR.

How should I proceed?
