Subject: If the value types are equal then this routine
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5d868b1ffedfb4917abcb3b41afa6e21d9160ff7;p=oota-llvm.git

If the value types are equal then this routine
asserts in later checks rather than producing
the ordinary load it is supposed to.  Avoid all
such hassles by directly returning an ordinary
load in this case.
