Subject: Use uint16_t to store indices into string table since C++ only allows 64K string... 
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=f0c094b1155e9316e93b28bfbd3153bc99d1ac95;p=oota-llvm.git

Use uint16_t to store indices into string table since C++ only allows 64K string literals so the index into the big string can never be larger than that.
