Subject: Fix some GCC warnings by providing a virtual destructor in the base of a class
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=54f616304240fcbc41ca9b9b2af38eeb1171e8a8;p=oota-llvm.git

Fix some GCC warnings by providing a virtual destructor in the base of a class
hierarchy with virtual methods and using llvm_unreachable to properly indicate
unreachable states which would otherwise leave variables uninitialized.
