Detailed Description

Represents analyses that only rely on functions' control flow.

This can be used with PreservedAnalyses to mark the CFG as preserved and to query whether it has been preserved.

The CFG of a function is defined as the set of basic blocks and the edges between them. Changing the set of basic blocks in a function is enough to mutate the CFG. Mutating the condition of a branch or argument of an invoked function does not mutate the CFG, but changing the successor labels of those instructions does.
