Subject: Handle AddrSpaceCast in stripAndAccumulateInBoundsConstantOffsets
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=07adbf3a870ab0ca8eb11534940aed2bf64af695;p=oota-llvm.git

Handle AddrSpaceCast in stripAndAccumulateInBoundsConstantOffsets

All of the other similar functions in that part of the file look through
addrspacecast in addition to bitcast, and I see no reason why
stripAndAccumulateInBoundsConstantOffsets shouldn't do so also.
