In the above example, beware that a register that is call-clobbered by
the target ABI will be overwritten by any function call in the
assignment, including library calls for arithmetic operators.
+Also a register may be clobbered when generating some operations,
+like variable shift, memory copy or memory move on x86.
Assuming it is a call-clobbered register, this may happen to @code{r0}
above by the assignment to @code{p2}. If you have to use such a
register, use temporary variables for expressions between the register
