Now we get

f1:
.LFB0:
        .cfi_startproc
        movzbl  (%rdi), %eax
        ret
f2:
.LFB1:
        .cfi_startproc
        movzbl  (%rdi), %eax
        ret
f3:
.LFB2:
        .cfi_startproc
        xorb    $1, (%rdi)
        ret
f4:
.LFB3:
        .cfi_startproc
        movb    $1, (%rdi)
        ret


thus, fixed.
