oacc_fn_attrib_level()

int oacc_fn_attrib_level ( tree attr )

extern

Return level at which oacc routine may spawn a partitioned loop, or
-1 if it is not a routine (i.e. is an offload fn).   

References integer_zerop(), TREE_CHAIN, TREE_PURPOSE, and TREE_VALUE.

Referenced by execute_oacc_loop_designation(), new_oacc_loop_routine(), and omp_sese_active_worker_call().

oacc_get_default_dim()

int oacc_get_default_dim ( int dim )

extern

Bits of OpenMP and OpenACC handling that is specific to device offloading
   and a lowering pass for OpenACC device directives.
