With the patch for PR 21520, we will get better code.
Right now on the mainline we get:
bar:
movl 4(%esp), %eax
testb $1, (%eax)
jne .L7
movl 8(%esp), %eax
movb (%eax), %al
andl $1, %eax
xorl $1, %eax
movzbl %al, %eax
ret
.p2align 2,,3
.L7:
xorl %eax, %eax
movzbl %al, %eax
ret
but after that patch we should be able to remove the extra movzbl in the second
branch.
