Subject: Do not drop a variable's complex address if it is not based on frame base.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=80925f5dca36e34c6c28ae080d2fd2bf861fb346;p=oota-llvm.git

Do not drop a variable's complex address if it is not based on frame base.
Observed this while reading code, so I do not have a test case handy here.
