Argh... OK, going through aranym with debugger has exhonorated it. My

extern int foo(int);
void *bar(int n)

return (void *)foo(n);
}
and gcc -S -O2 turns that into
bar:
link.w %fp,#0
unlk %fp
jra foo
I presume the bug is that foo put the return value in %d0 while bar
should have its return value in %a0. This function isn't eligible
for the optimization being used due to this need to move the result
into a different register.
Spot the obvious bug... BTW, why on the Earth does debian-ports m68k tree
use gcc-4.3 with Cthulhu-scaring 700Kb gzipped patch and does *not* have
gcc-4.4?
I believe that gcc-4.4 for m68k is being held up by the TLS support patches.
While I haven't been personally involved to any great degree, I got the
impression that the work is pretty much done other than getting it included.
