I'm sorry I forget to include "-fno-inline" as a compiler option I'm using. When
I compile without "-fno-inline" I do get the same code as you posted here. 

This is the code produced using this option:

        link.w %a6,#0
        move.l %d2,-(%sp)
        clr.b %d2
        lea Array,%a0
        tst.b (%a0)
        jbne .L18
        .align  2
.L7:
        addq.b #1,%d2
        cmp.b #5,%d2
        jbls .L7
        jbra .L16
        .align  2
.L18:
        jbsr _Z5func2v
        addq.b #1,%d2
        cmp.b #5,%d2
        jbhi .L16
        jbsr _Z5func2v
        addq.b #1,%d2
        cmp.b #5,%d2
        jbls .L18
.L16:
        move.l -4(%a6),%d2
        unlk %a6
        rts
