Represent the ILP of the subDAG rooted at a DAG node.
Declared in <llvm/CodeGen/ScheduleDFS.h>
struct ILPValue;ILPValues summarize the DAG subtree rooted at each node. ILPValues are valid for all nodes regardless of their subtree membership.
When computed using bottom-up DFS, this metric assumes that the DAG is a forest of trees with roots at the bottom of the schedule branching upward.
| Name | Description |
|---|---|
ILPValue [constructor] | Construct an ILP metric from an instruction count and a path length. |
dump | Dump this ILP value to the debug stream. |
print | Print this ILP value to OS. |
operator< | Return true if this ILP is strictly less than RHS. |
operator<= | Return true if this ILP is less than or equal to RHS. |
operator> | Return true if this ILP is strictly greater than RHS. |
operator>= | Return true if this ILP is greater than or equal to RHS. |
| Name | Description |
|---|---|
InstrCount | Number of instructions in the subDAG rooted at this node. |
Length | Length may either correspond to depth or height, depending on direction, and cycles or nodes depending on context. |
