Can this call throw externally?
Referenced by cgraph_clone_edge().
| gcov_type cgraph_edge::count |
Expected number of executions: calculated in profile.c.

| int cgraph_edge::frequency |
Expected frequency of executions within the function.
When set to CGRAPH_FREQ_BASE, the edge is expected to be called once
per function call. The range is 0 to CGRAPH_FREQ_MAX.

Additional information about an indirect call. Not cleared when an edge
becomes direct.

Whether this edge was made direct by indirect inlining.

| unsigned int cgraph_edge::indirect_unknown_callee |
Whether this edge describes an indirect call with an undetermined

When equal to CIF_OK, inline this call. Otherwise, points to the
explanation why function was not inlined.

| unsigned int cgraph_edge::speculative |
Edges with SPECULATIVE flag represents indirect calls that was
speculatively turned into direct (i.e. by profile feedback).
The final code sequence will have form:
if (call_target == expected_fn)
expected_fn ();
else
call_target ();
Every speculative call is represented by three components attached
to a same call statement:
1) a direct call (to expected_fn)
2) an indirect call (to call_target)
3) a IPA_REF_ADDR refrence to expected_fn.
Optimizers may later redirect direct call to clone, so 1) and 3)
do not need to necesarily agree with destination.

| int cgraph_edge::uid |
Unique id of the edge.
