FYI, this code looks OK to me on mainline, entering the loop at .L18:

.L29:
        andl    $-16, %edx
        cmpb    $80, %dl
        jne     .L27
        subl    $1, %ecx
        je      .L28
.L18:
        movl    $86, %edx
        movl    %edx, %eax
        andl    $7, %eax
        cmpb    $6, %al
        movb    $86, b_rec
        je      .L29
.L27:
        call    abort
.L28:

Still looks kind of sloppy in 4.1, though.

I haven't tried to figure out what fixed it on mainline.
