--- Comment #3 from Mikael Pettersson <mikpelinux at gmail dot com> ---
I can't reproduce with a vanilla gcc-4.8.3 configured for m68k-elf.  For the
"if (0x0 == haddr) ..." it generates:

        lea (20,%sp),%sp
        tst.l %d2
        seq %d2
        extb.l %d2
        neg.l %d2

which looks correct and matches your 4.7 output.

How was your gcc configured?
