Accessors for OMP context selectors, used by variant directives.
These are represented internally by a multilevel TREE_LIST structure, but
these accessors should be used to avoid confusion. The grammar is:
context-set-selector-specification:
trait-set-selector [, trait-set-selector [, ...]]
trait-set-selector:
trait-set-selector-name = { trait-selector [, trait-selector [, ... ]] }
trait-selector:
trait-selector-name [ ( [trait-score: ]
trait-property [, trait-property [, ...]] ) ]
trait-properties can variously be identifiers, strings, clauses, or
expressions.
All the lists are chained via TREE_CHAIN. If a score is present, it is
internally tacked on to the properties with a TREE_PURPOSE of
OMP_TS_SCORE_NODE.

Constructors for context selectors.
References build_int_cst(), integer_type_node, and tree_cons().
◆ oacc_build_routine_dims()
Process the OpenACC 'routine' directive clauses to generate an attribute for the level of parallelism. All dimensions have a size of zero (dynamic). TREE_PURPOSE is set to indicate whether that dimension can have a loop partitioned on it. non-zero indicates yes, zero indicates no. By construction once a non-zero has been reached, further inner dimensions must also be non-zero. We set TREE_VALUE to zero for the dimensions that may be partitioned and 1 for the other ones -- if a loop is (erroneously) spawned at an outer level, we don't want to try and partition it.

|
extern |
Extract an oacc execution dimension from FN. FN must be an offloaded function or routine that has already had its execution dimensions lowered to the target-specific values.

Referenced by expand_omp_target(), oacc_set_fn_attrib(), and oacc_validate_dims().
◆ oacc_replace_fn_attrib_attr()
Openacc compute grid dimension clauses are converted to an attribute attached to the function. This permits the target-side code to (a) massage the dimensions, (b) emit that data and (c) optimize. Non-constant dimensions are pushed onto ARGS. The attribute value is a TREE_LIST. A set of dimensions is represented as a list of INTEGER_CST. Those that are runtime exprs are represented as an INTEGER_CST of zero. TODO: Normally the attribute will just contain a single such list. If however it contains a list of lists, this will represent the use of device_type. Each member of the outer list is an assoc list of dimensions, keyed by the device type. The first entry will be the default. Well, that's the plan.
Replace any existing oacc fn attribute in ATTRIBS with updated dimensions.
References get_identifier(), OACC_FN_ATTRIB, TREE_CHAIN, tree_cons(), and TREE_PURPOSE.
Referenced by oacc_replace_fn_attrib().
◆ oacc_set_fn_attrib()

◆ oacc_verify_routine_clauses()
|
extern |
Verify OpenACC routine clauses. Returns 0 if FNDECL should be marked with an OpenACC 'routine' directive, 1 if it has already been marked in compatible way, and -1 if incompatible. Upon returning, the chain of clauses will contain exactly one clause specifying the level of parallelism.

◆ omp_check_optional_argument()
Check whether this DECL belongs to a Fortran optional argument. With 'for_present_check' set to false, decls which are optional parameters themselve are returned as tree - or a NULL_TREE otherwise. Those decls are always pointers. With 'for_present_check' set to true, the decl for checking whether an argument is present is returned; for arguments with value attribute this is the hidden argument and of BOOLEAN_TYPE. If the decl is unrelated to optional arguments, NULL_TREE is returned.
