Enumeration Type Documentation

◆ access_method_kinds

enum omp_addr_tokenizer::access_method_kinds 
These are the ways of accessing a variable that have special-case handling
in the middle end (gimplify, omp-lower, etc.).   
These are the kinds of access that an ACCESS_METHOD token can represent.
Enumerator
ACCESS_DIRECT 
ACCESS_REF 
ACCESS_POINTER 
ACCESS_REF_TO_POINTER 
ACCESS_POINTER_OFFSET 
ACCESS_REF_TO_POINTER_OFFSET 
ACCESS_INDEXED_ARRAY 
ACCESS_INDEXED_REF_TO_ARRAY 

◆ structure_base_kinds

enum omp_addr_tokenizer::structure_base_kinds 
These are the kinds that a STRUCTURE_BASE or ARRAY_BASE (except
BASE_COMPONENT_EXPR) can represent.
Enumerator
BASE_DECL 
BASE_COMPONENT_EXPR 
BASE_ARBITRARY_EXPR 

◆ token_type

enum omp_addr_tokenizer::token_type 
The coarse type for an address token.  These can have subtypes for
ARRAY_BASE or STRUCTURE_BASE (structure_base_kinds) or ACCESS_METHOD
(access_method_kinds).
Enumerator
ARRAY_BASE 
STRUCTURE_BASE 
COMPONENT_SELECTOR 
ACCESS_METHOD 

Function Documentation

◆ omp_access_chain_p()

bool omp_addr_tokenizer::omp_access_chain_p ( vec< omp_addr_token * > & addr_tokens,
unsigned i ) 
Return TRUE if the ACCESS_METHOD token at index 'i' has a further
ACCESS_METHOD chained after it (e.g., if we're processing an expression
containing multiple pointer indirections).

References ACCESS_METHOD, gcc_assert, and i.

◆ omp_accessed_addr()

tree omp_addr_tokenizer::omp_accessed_addr ( vec< omp_addr_token * > & addr_tokens,
unsigned i,
tree expr ) 
Return the address of the object accessed by the ACCESS_METHOD token
at 'i': either of the next access method's expr, or of EXPR if we're at
the end of the list of tokens.

References build_fold_addr_expr, and i.
