WebExtended basic block (EBB) An EBBis a set of blocks B1, B2, ..., Bn, where Bi, 2<= i<= n has a unique predecessor, which is in the EBB.(If a block is added to the EBB, all of its predecessors must be included. Bi is the one with on predecessor, i.e., the root of the EBB). m ¬a + b n ¬a + b A p ¬c + d r ¬c + d B WebBlock B1 is contained in two extended basic blocks: fB1;B2gand fB1;B3g. These blocks are related by a common prefix. In fact, if the intersection of two extended basic blocks is non-empty, it must be a common prefix of both. Thus, a collection of extended basic blocks related by intersection forms a tree, and the trees form a forest ...
