emptyAGraph :: AGraph m lSource
A graph is built up by splicing together graphs each containing a single node (where a label is considered a first node. The empty graph is a left and right unit for splicing. All of the AGraph constructors (even complex ones like mkIfThenElse, as well as the splicing operation *, are constant-time operations.
withFreshLabel :: String -> (BlockId -> AGraph m l) -> AGraph m lSource
This function provides access to fresh labels without requiring clients to be programmed monadically.
withUnique :: (Unique -> AGraph m l) -> AGraph m lSource
outOfLine :: (LastNode l, Outputable m, Outputable l) => AGraph m l -> AGraph m lSource

The argument is an AGraph that has an empty entry sequence and no exit sequence. The result is a new AGraph that has an empty entry sequence connected to an empty exit sequence, with the original graph sitting to the side out-of-line.

Example: mkMiddle (x = 3) *> outOfLine (mkLabel L <* ...stuff...) * mkMiddle (y = x) Control will flow directly from x=3 to y=x; the block starting with L is on the side.

N.B. algebraically forall g g' : g *> outOfLine g' == outOfLine g' <* g

lgraphOfAGraphSource
:: AGraph m l
-> UniqSM (LGraph m l)allocate a fresh label for the entry point
graphOfAGraph :: AGraph m l -> UniqSM (Graph m l)Source
Converting an abstract graph to a concrete form is expensive: the cost is linear in the number of nodes in the answer, plus N log N in the number of basic blocks. The conversion is also monadic because it may require the allocation of fresh, unique labels.
labelAGraphSource
:: BlockId
-> AGraph m l
-> UniqSM (LGraph m l)use the given BlockId as the label of the entry point
