Subject: Do not merge jump tables this early. Branch folding will do any necessary
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=c04cae9c9b420133ff2fc80c183c3fe0449d2ae1;p=oota-llvm.git

Do not merge jump tables this early. Branch folding will do any necessary
merges, and until then, it's useful to keep the tables separate for ease
of manipulation.
