Looks fine to me. The instruction choice is still pretty odd:
1a: f6 c3 ff test $0xff,%bl
1d: 74 02 je 21 <bar+0x21>
that "test $0xff,%bl" is a rather odd way of testing the byte for zero, since
1a: 84 db test %bl,%bl
1c: 74 02 je 20 <bar+0x20>
would have been a byte shorter and is the canonical way on x86 to test
a register against zero.
But that's just a "looks odd to somebody who is used to x86 asm", not
a bug or anything really noticeable.
