Expand description

The origin of a block in the lowered block-order: either an original CLIF block, or an inserted edge-block, or a combination of the two if an edge is non-critical.

Variants

Orig

Block in original CLIF, with no merged edge-blocks.

Show fields

Fields of Orig

block: Block

Original CLIF block.

OrigAndEdge

Block in the original CLIF, plus edge-block to one succ (which is the one successor of the original block).

Show fields

Fields of OrigAndEdge

block: Block

The original CLIF block contained in this lowered block.

edge_inst: Inst

The edge (jump) instruction transitioning from this block to the next, i.e., corresponding to the included edge-block. This will be an instruction in block.

succ: Block

The successor CLIF block.

EdgeAndOrig

Block in the original CLIF, preceded by edge-block from one pred (which is the one pred of the original block).

Show fields

Fields of EdgeAndOrig

pred: Block

The previous CLIF block, i.e., the edge block’s predecessor.

edge_inst: Inst

The edge (jump) instruction corresponding to the included edge-block. This will be an instruction in pred.

block: Block

The original CLIF block included in this lowered block.

Edge

Split critical edge between two CLIF blocks. This lowered block does not correspond to any original CLIF blocks; it only serves as an insertion point for work to happen on the transition from pred to succ.

Show fields

Fields of Edge

pred: Block

The predecessor CLIF block.

edge_inst: Inst

The edge (jump) instruction corresponding to this edge’s transition. This will be an instruction in pred.

succ: Block

The successor CLIF block.
