Subject: Use getPrevSlot() instead of getPrevIndex().
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a1dd30553da772a1702924bf1651f63fa5df7894;p=oota-llvm.git

Use getPrevSlot() instead of getPrevIndex().

The getPrevIndex() function moves to the same slot in the previous
instruction.  For getVNInfoBefore(), we just need the previous slot in
the same instruction.
