Comment #7 in PR18542 said that separate PR's

I am going to reopen them and remove the avr/h8300 from PR18542.
You can easily check that by testing if reverting the patch from comment #2
helps.
Please read what I wrote in comment #10.

PR18542 and this PR are not identical:
Proof:
* Compiling the example from comment #3
# m68k-rtems4.7-gcc -m68020 -O2 -o tmp.o -c pr18549.c
pr18549.c: In function `foo':

And you also need -m68020 to trigger the bug. Works
fine with -m68000, so the bug must hide in one of the
TARGET_68020 patterns.

It happens both on ColdFire and 680x0 (x=2), but not
on 68000.
output_addr_const() gets passed a TRUNCATE (HImode) rtx.
I could find it in the last dump before the ICE:

I.e. though this PR and PR18542 might be the same for the m68k, I doubt this
bug
to be identical to the ICE on the avr.
You can easily check that by testing if reverting the patch from comment #2
helps.
