Documentation
type CmmAGraph = OrdList CgStmt Source #
CmmAGraph is a chunk of code consisting of:
- ordinary statements (assignments, stores etc.)
- jumps
- labels
- out-of-line labelled blocks
The semantics is that control falls through labels and out-of-line blocks. Everything after a jump up to the next label is by definition unreachable code, and will be discarded.
Two CmmAGraphs can be stuck together with *, with the meaning that control flows from the first to the second.
A CmmAGraph can be turned into a CmmGraph (closed at both ends)
by providing a label for the entry point and a tick scope; see
labelAGraph.
type CmmAGraphScoped = (CmmAGraph, CmmTickScope) Source #
Unlabeled graph with tick scope
catAGraphs :: [CmmAGraph] -> CmmAGraph Source #
mkLabel :: BlockId -> CmmTickScope -> CmmAGraph Source #
created a sequence "goto id; id:" as an AGraph
outOfLine :: BlockId -> CmmAGraphScoped -> CmmAGraph Source #
A labelled code block; should end in a last node
lgraphOfAGraph :: CmmAGraphScoped -> UniqSM CmmGraph Source #
allocate a fresh label for the entry point
labelAGraph :: BlockId -> CmmAGraphScoped -> CmmGraph Source #
use the given BlockId as the label of the entry point
stackStubExpr :: Width -> CmmExpr Source #
mkUnsafeCall :: ForeignTarget -> [CmmFormal] -> [CmmActual] -> CmmAGraph Source #
mkFinalCall :: DynFlags -> CmmExpr -> CCallConv -> [CmmExpr] -> UpdFrameOffset -> CmmAGraph Source #
mkCallReturnsTo :: DynFlags -> CmmExpr -> Convention -> [CmmExpr] -> BlockId -> ByteOff -> UpdFrameOffset -> [CmmExpr] -> CmmAGraph Source #
mkJumpReturnsTo :: DynFlags -> CmmExpr -> Convention -> [CmmExpr] -> BlockId -> ByteOff -> UpdFrameOffset -> CmmAGraph Source #
mkJump :: DynFlags -> Convention -> CmmExpr -> [CmmExpr] -> UpdFrameOffset -> CmmAGraph Source #
mkJumpExtra :: DynFlags -> Convention -> CmmExpr -> [CmmExpr] -> UpdFrameOffset -> [CmmExpr] -> CmmAGraph Source #
mkRawJump :: DynFlags -> CmmExpr -> UpdFrameOffset -> [GlobalReg] -> CmmAGraph Source #
A jump where the caller says what the live GlobalRegs are. Used for low-level hand-written Cmm.
mkComment :: FastString -> CmmAGraph Source #
mkCallEntry :: DynFlags -> Convention -> [CmmFormal] -> [CmmFormal] -> (Int, [GlobalReg], CmmAGraph) Source #
mkUnwind :: GlobalReg -> CmmExpr -> CmmAGraph Source #
Construct a CmmUnwind node for the given register and unwinding
expression.
