init_node_map()

void init_node_map ( bool local )

extern

Initialize map from PROFILE_ID to CGRAPH_NODE.
When LOCAL is true, the PROFILE_IDs are computed.  when it is false we assume
that the PROFILE_IDs was already assigned.

mcf_smooth_cfg()

void mcf_smooth_cfg ( void )

extern

Smoothes the initial assigned basic block and edge counts using
a minimum cost flow algorithm.  

Main routine. Smoothes the initial assigned basic block and edge counts using
a minimum cost flow algorithm, to ensure that the flow consistency rule is
obeyed: sum of outgoing edges = sum of incoming edges for each basic
block.
