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.  

Referenced by gimple_call_arg_flags().

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
