◆ OMP_TS_SCORE_NODE

#define OMP_TS_SCORE_NODE   integer_minus_one_node
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.

◆ oacc_build_routine_dims()

tree oacc_build_routine_dims ( tree clauses)
extern
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.

dimensions.

◆ oacc_replace_fn_attrib_attr()

tree oacc_replace_fn_attrib_attr ( tree attribs,
tree dims )
extern
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.

◆ oacc_set_fn_attrib()

function attribute.  Push any that are non-constant onto the ARGS
list, along with an appropriate GOMP_LAUNCH_DIM tag.

◆ oacc_verify_routine_clauses()

int oacc_verify_routine_clauses ( tree fndecl,

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_context_selector()

◆ omp_check_optional_argument()

tree omp_check_optional_argument ( tree decl,
bool for_present_check )
extern
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.

CTX is a list of trait selectors, nconstructs must be equal to its
length, and the array CONSTRUCTS holds the output.

Some properties can be checked right away during parsing (this routine),
others need to wait until the whole TU is parsed, others need to wait until
IPA, others until vectorization.
