            Bug ID: 104028
           Summary: M68k: Error: value -16034 out of range
           Product: gcc
           Version: 10.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: giulio.benetti at benettiengineering dot com
  Target Milestone: ---

When building package sg3_utils on buildroot we get this error:
```
/home/peko/autobuild/instance-0/output-1/host/bin/m68k-linux-gcc
-DHAVE_CONFIG_H -I. -I..  -iquote ../include -D_LARGEFILE64_SOURCE

23149
make[3]: *** [Makefile:1176: sg_vpd.o] Error 1
```

To reproduce it:
```
# git clone git://git.busybox.net/buildroot
# cd buildroot
# git checkout feb9185fc185c1f76e3789b0dc521e3cf98c1ebb
# wget -O .config
http://autobuild.buildroot.net/results/c49300d12a209b18f41d389f092324592b881277/config
# make olddefconfig && make
```

I'm going to add the preprocessed files.

Please provide output of m68k-linux-gcc with -v option.

This is the output log with -v. Now it's built not in parallel and the file
where gcc fails is not sg_dd.c so I'm going to update .i and .s files.

Note that bug is still present in gcc 11.2.0 so it's probable it's still in
master branch.

Thank you for taking care.

It's a duplicated case vector load, where the second one is placed far off from
its table.

The reduced test case stopped failing in gcc >= 12 with

# first new commit: [2e96b5f14e4025691b57d2301d71aa6092ed44bc] Backwards jump
threader rewrite with ranger.

but the original test case (sg_vpd.i) still fails with current master.
