Subject: There is not a 1-1 mappign between llvm blocks and PPC blocks, do not use
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=b752a97ca41de789434fa792b6de01f6c04fe13e;p=oota-llvm.git

There is not a 1-1 mappign between llvm blocks and PPC blocks, do not use
LLVM blocks as the keys for the branch rewriter.  This fixes treeadd and
many other programs with the JIT.
