Function Documentation

add_builtin_function()

tree add_builtin_function ( const char * name, tree type, int function_code, enum built_in_class cl, const char * library_name, tree attrs )

extern

Create a builtin function.   

References build_builtin_function(), lang_hooks::builtin_function, and BUILTINS_LOCATION.

Referenced by local_define_builtin(), and tree_ssa_prefetch_arrays().

add_builtin_function_ext_scope()

tree add_builtin_function_ext_scope ( const char * name, tree type, int function_code, enum built_in_class cl, const char * library_name, tree attrs )

extern

Like add_builtin_function, but make sure the scope is the external scope.
This is used to delay putting in back end builtin functions until the ISA
that defines the builtin is declared via function specific target options,
which can save memory for machines like the x86_64 that have multiple ISAs.
If this points to the same function as builtin_function, the backend must
add all of the builtins at program initialization time.

add_builtin_type()

tree add_builtin_type ( const char * name, tree type )

extern

Create a builtin type.

lang_GNU_C()

bool lang_GNU_C ( void )

extern

Language helper functions.   

Returns true if the current lang_hooks represents the GNU C frontend.   

References lang_hooks::name, and startswith().

Referenced by default_floatn_builtin_p(), maybe_warn_implicit_fallthrough(), and process_options().

lang_GNU_CXX()

bool lang_GNU_CXX ( void )

extern

Returns true if the current lang_hooks represents the GNU C++ frontend.   

References lang_hooks::name, and startswith().

Referenced by fold_cond_expr_with_comparison(), and maybe_warn_implicit_fallthrough().

lang_GNU_Fortran()

bool lang_GNU_Fortran ( void )

extern

Returns true if the current lang_hooks represents the GNU Fortran frontend.   

References lang_hooks::name, and startswith().

Referenced by check_omp_nesting_restrictions(), gimplify_bind_expr(), gimplify_omp_for(), gimplify_omp_loop(), gimplify_scan_omp_clauses(), maybe_warn_switch_unreachable_and_auto_init(), omp_accumulate_sibling_list(), omp_context_name_list_prop(), and omp_default_clause().

lang_GNU_OBJC()

bool lang_GNU_OBJC ( void )

extern

Returns true if the current lang_hooks represents the GNU Objective-C
frontend.   

References lang_hooks::name, and startswith().

Referenced by default_floatn_builtin_p(), and maybe_warn_implicit_fallthrough().

simulate_builtin_function_decl()

tree simulate_builtin_function_decl ( location_t location, const char * name, tree type, int function_code, const char * library_name, tree attrs )

extern

Simulate a declaration of a target-specific built-in function at
location LOCATION, as though it had been declared directly in the
source language.  NAME is the name of the function, TYPE is its function
type, FUNCTION_CODE is the target-specific function code, LIBRARY_NAME
is the name of the underlying library function (NULL if none) and
ATTRS is a list of function attributes.

Return the decl of the declared function.
