Subject: Handle AddrSpaceCast in stripAndAccumulateInBoundsConstantOffsets
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b8e7c736fba3150a6576cdc398bcd4ea1df9652e;p=platform%2Fupstream%2Fllvm.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.
