--- Comment #7 from Jeffrey A. Law <law at redhat dot com> --- The other thing to keep in mind, sinking of this nature ought to be applicable to other unary ops and cases where we have multiple PHI args that are SSA_NAMEs. It shouldn't be structurally limited to just conversions where one arg is an SSA_NAME and the other a constant.
