in_pragma_suppress_coverage_p()

bool in_pragma_suppress_coverage_p ( gimple * stmt, bool prev )

extern

For #pragma GCC suppress_coverage begin/end.   

Check if STMT is anchored to a line of code in a range disabled by #pragma
GCC suppress_coverage begin/end.  This function always returns false if
coverage is disabled as it is the faster check, and nothing should be
suppressed anyway.

If STMT is at an UNKNOWN_LOCATION or ADHOC_LOC, this function returns PREV.
This is probably a compiler-generated statement that should inherit the
disabled state of the previous statement since it is really tied to it, and
there is no opportunity for a #pragma in-between.

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.
