A predecessor of a basic block in a control flow graph is another block that has an edge leading to the block in question, indicating a possible control flow that comes from the predecessor.

Loops in a control flow graph appear as a cycle where one or more basic blocks are re-entered through back edges before exiting a section of the graph.

In a control flow graph, conditional statements cause branches, leading to multiple possible paths represented by edges coming out of the basic block containing the conditional statement.

Control flow graphs are used in compiler optimizations to analyze and manipulate the program's execution flow, allowing for the identification of loops, unreachable code, and optimization opportunities such as reordering instructions for better pipeline efficiency.

A control flow graph represents the order in which the basic blocks of a program are executed, illustrating possible paths that can be taken during the program execution.

Edges in a control flow graph signify the control flow paths from one basic block to another, representing the possible execution paths through the program.

In a control flow graph, a dominator of a node N is a node D such that every path from the start node to N must go through D. If D is a dominator of N, N is said to be dominated by D.

A basic block is a sequence of consecutive statements in which the flow of control enters at the beginning and leaves at the end without any possibility of branching except at the end.

A successor of a basic block is another block that is reachable directly from the block in question through one of its outgoing edges.
