Done, attached is a modified patch witout duplication.
Thanks, comment with one small change: you cannot first release both
EDX and EAX, then allocate 2 new registers and move EDX and EAX into
them. The reason is that in this case the first allocated register may
be mapped to EAX by the register allocator, so you can get this in the
end:
movl %edx, %eax
movl %eax, %ecx
or even
movl %edx, %eax
movl %eax, %edx
