Subject: While working on the pool allocator, I noticed that basicaa is failing a scary
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2bde8bdc161aa2edfa0d6a22a75f7af15130c584;p=oota-llvm.git

While working on the pool allocator, I noticed that basicaa is failing a scary
number of simple cases.  Someday when I get a chance to work on it again, this
testcase should be corrected.
