  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 };

  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.

Create a complex type whose components are COMPONENT_TYPE.

If NAMED is true, the type is given a TYPE_NAME.  We do not always

dependent on the type canonicalization hashtable, which is GC-ed,
so the DECL_UIDs would not be stable wrt garbage collection.

◆ build_index_type()

tree build_index_type ( tree maxval )

The limit exists because the result is a signed type and we don't handle
sizes that use more than one HOST_WIDE_INT.

returned by the function.  The function takes N named arguments, the
types of which are provided in ARG_TYPES.

◆ build_varargs_function_type_list()

◆ build_variant_type_copy()

tree build_variant_type_copy ( tree type MEM_STAT_DECL )

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.

◆ 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.

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.

never loses precision.  However, the signedness of the result does
not necessarily match the signedness of T: sometimes an unsigned type

we stripped off while looking for the inner type.  Similarly for
return values from functions.

◆ save_expr()

tree save_expr ( tree expr )

Wrap a SAVE_EXPR around EXPR, if appropriate.
Do this to any expression which may be used in more than one place,
but must be evaluated only once.

Normally, expand_expr would reevaluate the expression each time.
Calling save_expr produces something that is evaluated and recorded
the first time expand_expr is called on it.  Subsequent calls to
expand_expr just reuse the recorded value.

The call to expand_expr that generates code that actually computes
the value is the first call *at compile time*.  Subsequent calls
*at compile time* generate code to use the saved value.
This produces correct result provided that *at run time* control
always flows through the insns made by the first expand_expr
before reaching the other places where the save_expr was evaluated.
You, the caller of save_expr, must make sure this is so.

Constants, and certain read-only nodes, are returned with no
SAVE_EXPR because that is safe.  Expressions containing placeholders
are not touched; see tree.def for an explanation of what these
are used for.

◆ stabilize_reference_1()

static tree stabilize_reference_1 ( tree e )

static

Subroutine of stabilize_reference; this is called for subtrees of

to ensure that it is only evaluated once.

We don't put SAVE_EXPR nodes around everything, because assigning very
simple expressions to temporaries causes us to miss good opportunities
for optimizations.  Among other things, the opportunity to fold in the
addition of a constant into an addressing mode often gets lost, e.g.
"y[i+1] += x;".  In general, we take the approach that we should not make
an assignment unless we are forced into it - i.e., that any non-side effect
operator should be allowed, and that cse should take care of coalescing
multiple utterances of the same expression should that prove fruitful.

◆ type_with_interoperable_signedness()

bool type_with_interoperable_signedness ( const_tree type )

The TYPE_CANONICAL merging machinery.  It should closely resemble
the middle-end types_compatible_p function.  It needs to avoid
claiming types are different for types that should be treated
the same with respect to TBAA.  Canonical types are also used
for IL consistency checks via the useless_type_conversion_p
predicate which does not handle all type kinds itself but falls
back to pointer-comparison of TYPE_CANONICAL for aggregates
for example.

Return true if TYPE_UNSIGNED of TYPE should be ignored for canonical
type calculation because we need to allow inter-operability between signed
and unsigned variants.

◆ variably_modified_type_p()

bool variably_modified_type_p	(	tree	type,

Returns true if T is, contains, or refers to a type with variable
size.  For METHOD_TYPEs and FUNCTION_TYPEs we exclude the
arguments, but not the return type.  If FN is nonzero, only return
true if a modifier of the type or position of FN is a variable or
parameter inside FN.

This concept is more general than that of C99 'variably modified types':
in C99, a struct type is never variably modified because a VLA may not
appear as a structure member.  However, in GNU C code like:

  struct S { int i[f()]; };

is valid, and other languages may define similar constructs.

Test if T is either variable (if FN is zero) or an expression containing
a variable in FN.  If TYPE isn't gimplified, return true also if
gimplify_one_sizepos would gimplify the expression into a local
variable.

tree vector_element_bits_tree ( const_tree type )

◆ vector_type_mode()

machine_mode vector_type_mode ( const_tree t )

Vector types need to re-check the target flags each time we report
the machine mode.  We need to do this because attribute target can
change the result of vector_mode_supported_p and have_regs_of_mode
on a per-function basis.  Thus the TYPE_MODE of a VECTOR_TYPE can
change on a per-function basis.

??? Possibly a better solution is to run through all the types
referenced by a function and re-compute the TYPE_MODE once, rather
than make the TYPE_MODE macro call a function.

Create an INT_CST node of TYPE and value CST.
The returned node is always shared.  For small integers we use a
per-type vector cache, for larger ones we use a single hash table.
The value is extended from its precision according to the sign of
the type to be a multiple of HOST_BITS_PER_WIDE_INT.  This defines
the upper bits and ensures that hashing and value equality based
upon the underlying HOST_WIDE_INTs works without masking.
