omp_find_combined_for()

tree omp_find_combined_for ( gimple_stmt_iterator * gsi_p, bool * handled_ops_p, struct walk_stmt_info * wi )

extern

Callback for walk_gimple_seq.  Check if combined parallel
contains gimple_omp_for_combined_into_p OMP_FOR.

omp_member_access_dummy_var()

tree omp_member_access_dummy_var ( tree decl )

extern

If DECL is the artificial dummy VAR_DECL created for non-static
data member privatization, return the underlying "this" parameter,
otherwise return NULL.
