In CSiBE cg_compiler_opensrc/compile.c I've spotted the following code:


        .align 1
.L1012:
        mov     #7,r5
        jsr     @r1
        mov     #24,r4
        mov.l   @(8,r15),r1
        mov     r0,r11
        mov.l   @r1,r2
        bra     .L891
        mov.l   r2,@(4,r0)
        bra     .L908            <<< unreachable branch
        nop
        .align 1
