[Bug c/42522] [m68k] Wrong code generated with -O2/-O3

[ami_stuff at o2 dot pl]

------- Comment #3 from ami_stuff at o2 dot pl  2009-12-28 20:38 -------
No, asm code looks the same like with -O2 option:

_flv_probe:
        clr.l d0
        rts
        .even


Here are GCC's options which I used (should be included in the first post):

$ make_68k_v45
