Detailed Description
A structure to group all the per-function control flow graph data. The x_* prefixing is necessary because otherwise references to the fields of this struct are interpreted as the defines for backward source compatibility following the definition of this struct.
Field Documentation
| int control_flow_graph::last_label_uid |
UIDs for LABEL_DECLs.
| int control_flow_graph::max_jumptable_ents |
Maximal number of entities in the single jumptable. Used to estimate final flowgraph size.
| vec<basic_block, va_gc>* control_flow_graph::x_basic_block_info |
Index by basic block number, get basic block struct info.
| enum dom_state control_flow_graph::x_dom_computed[2] |
Whether the dominators and the postdominators are available.
| basic_block control_flow_graph::x_entry_block_ptr |
Block pointers for the exit and entry of a function. These are always the head and tail of the basic block list.
| basic_block control_flow_graph::x_exit_block_ptr |
| vec<basic_block, va_gc>* control_flow_graph::x_label_to_block_map |
Mapping of labels to their associated blocks. At present only used for the gimple CFG.
Referenced by replace_ssa_name().
| int control_flow_graph::x_last_basic_block |
The first free basic block number.
| int control_flow_graph::x_n_basic_blocks |
Number of basic blocks in this flow graph.
| unsigned control_flow_graph::x_n_bbs_in_dom_tree[2] |
Number of basic blocks in the dominance tree.
| int control_flow_graph::x_n_edges |
Number of edges in this flow graph.
| enum profile_status_d control_flow_graph::x_profile_status |
