--- Comment #4 from Jeffrey A. Law <law at redhat dot com> ---
Fixed by the combination of a variety of commits through the last few years.
Now we get:
movl 4(%esp), %eax
movl (%eax), %edx
movl 8(%esp), %eax
testl %edx, %edx
movl (%eax), %eax
je .L2
movl (%edx), %ecx
xorl %edx, %edx
testl %eax, %eax
je .L3
.L5:
movl (%eax), %edx
.L3:
movl %ecx, %eax
subl %edx, %eax
cmpl %ecx, %edx
movl $0, %edx
cmove %edx, %eax
ret
.p2align 4,,7
.p2align 3
.L2:
xorl %ecx, %ecx
testl %eax, %eax
jne .L5
ret
