Subject: It doesn't matter what the 2nd operand is; if the GEP has 2 operands and
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=08cc64ebfe7d7026ad4f6d471a78427daf2ef167;p=oota-llvm.git

It doesn't matter what the 2nd operand is; if the GEP has 2 operands and
the first is a zero, we should leave it alone.
