--- Comment #2 from Oleg Endo <olegendo at gcc dot gnu.org> ---
I've tried the above test case with LRA on (sh-lra branch, not fully working
yet) and it produces the following code:

        mov     r5,r0
        mov.b   @(r0,r4),r0
        cmp/eq  #92,r0
        bt      .L3
        mov     r7,r0
        rts
        nop
    .align 1
.L3:
    rts
    mov     r6,r0

i.e. the problem is gone.
