--- Comment #5 from Uroš Bizjak <ubizjak at gmail dot com> ---
Mainline now generates:
foo:
cmpl $5, %eax
ja .L3
movl %eax, %ecx
movl $1, %edx
sall %cl, %edx
andl $42, %edx
setne %al
movzbl %al, %eax
ret
.L3:
xorl %eax, %eax
(*) movzbl %al, %eax
ret
movzbl at (*) is not needed, but original problem is gone.
So, fixed.
