WebDAG representation of a basic block allows Automatic detection of local common sub expressions Detection of induction variables Automatic detection of loop variant None of … WebThe basic block of each leader contains all the instructions from itself until just before the next leader. Thus, the basic block of 1 is just 1, for leader 2 the block is just 2. Leader 3, however, has a basic block consisting of instructions 3 through 9, inclusive.

"WebSep 16, 2013 · In the general case, this is impossible because BBs don't form a DAG. A topological order is only defined for a DAG - a graph without cycles; BBs within a function may form cycles (loops, etc). Your best approximation IMHO is to decompose the BB graph into SCCs (Strongly Connected Components). " - Dag for basic block
