Returns true if REF is an array reference, a component reference,

  than its upper bound implies, there are multiple cases:
  A. a ref to a flexible array member at the end of a structure;
  B. a ref to an array with a different type against the original decl;
     for example:

  short a[16] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 };

  C. a ref to an array that was passed as a parameter;
     for example:

  int test (uint8_t *p, uint32_t t[1][1], int n) {
  for (int i = 0; i < 4; i++, p++)
    t[i][0] = ...;

  If non-null, set IS_TRAILING_ARRAY to true if the ref is the above case A.

◆ build_varargs_function_type_array()

tree build_varargs_function_type_array	(	tree	return_type,
		int	n,
		tree *	arg_types )

Build a variable argument function type.  RETURN_TYPE is the type
returned by the function.  The function takes N named arguments, the
types of which are provided in ARG_TYPES.

References build_function_type_array_1().

◆ build_varargs_function_type_list()

tree build_varargs_function_type_list	(	tree	return_type,

Build a variable argument function type.  The RETURN_TYPE is the
type returned by the function.  If additional arguments are provided,
they are additional argument types.  The list of argument types must
always be terminated by NULL_TREE.

◆ build_variant_type_copy()

tree build_variant_type_copy ( tree type MEM_STAT_DECL )

Create a new variant of TYPE, equivalent but distinct.  This is so
the caller can modify it. TYPE_CANONICAL for the return type will
be equivalent to TYPE_CANONICAL of TYPE, indicating that the types
are considered equal by the language itself (or that both types
require structural equality checks).

overflow of the value, when >0 we are only interested in signed
overflow, for <0 we are interested in any overflow.  OVERFLOWED
indicates whether overflow has already occurred.  CONST_OVERFLOWED
indicates whether constant overflow has already occurred.  We force
T's value to be within range of T's type (by setting to 0 or 1 all
the bits outside the type's range).  We set TREE_OVERFLOWED if,
     OVERFLOWED is nonzero,
     or OVERFLOWABLE is >0 and signed overflow occurs
     or OVERFLOWABLE is <0 and any overflow occurs
We return a new tree node for the extended wide_int.  The node
is shared if no overflow flags are set.

Stores bounds of an integer TYPE in MIN and MAX.  If TYPE has non-constant
bounds or is a POINTER_TYPE, the maximum and/or minimum values that can be
represented (assuming two's-complement arithmetic) within the bit
precision of the type are returned instead.

◆ get_unwidened()

tree get_unwidened	(	tree	op,
		tree	for_type )

Return OP, stripped of any conversions to wider types as much as is safe.
Converting the value back to OP's type makes a value equivalent to OP.

If FOR_TYPE is nonzero, we return a value which, if converted to
type FOR_TYPE, would be equivalent to converting OP to type FOR_TYPE.

OP must have integer, real or enumeral type.  Pointers are not allowed!

There are some cases where the obvious value we could return
would regenerate to OP if converted to OP's type,
but would not extend like OP to wider types.
If FOR_TYPE indicates such extension is contemplated, we eschew such values.
For example, if OP is (unsigned short)(signed char)-1,
we avoid returning (signed char)-1 if FOR_TYPE is int,
even though extending that to an unsigned short would regenerate OP,
since the result of extending (signed char)-1 to (int)
is different from (int) OP.

◆ gimple_canonical_types_compatible_p()

bool gimple_canonical_types_compatible_p	(	const_tree	t1,
		const_tree	t2,
		bool	trust_type_canonical )

Return true iff T1 and T2 are structurally identical for what
TBAA is concerned.  
This function is used both by lto.cc canonical type merging and by the
verifier.  If TRUST_TYPE_CANONICAL we do not look into structure of types
that have TYPE_CANONICAL defined and assume them equivalent.  This is useful
only for LTO because only in these cases TYPE_CANONICAL equivalence
correspond to one defined by gimple_canonical_types_compatible_p.
