◆ array_ref_element_size()

◆ array_ref_flexible_size_p()

bool array_ref_flexible_size_p ( tree ref,
bool * is_trailing_array )
Returns true if REF is an array reference, a component reference,
  or a memory reference to an array whose actual size might be larger
  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 };
  (*((char(*)[16])&a[0]))[i+8]

  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.

◆ block_may_fallthru()

bool block_may_fallthru ( const_tree block)
Try to determine if we can fall out of the bottom of BLOCK.  This guess
need not be 100% accurate; simply be conservative and return true if we
don't know.  This is used only to avoid stupidly generating extra code.
If we're wrong, we'll just delete the extra code later.

tree build_function_type ( tree value_type,

bool no_named_args_stdarg_p )
Construct, lay out and return
the type of functions returning type VALUE_TYPE
given arguments of types ARG_TYPES.
ARG_TYPES is a chain of TREE_LIST nodes whose TREE_VALUEs
are data type nodes for the arguments of the function.
NO_NAMED_ARGS_STDARG_P is true if this is a prototyped
variable-arguments function with (...) prototype (no named arguments).
If such a type has already been constructed, reuse it.

◆ build_index_type()

tree build_index_type ( tree maxval)
Create a type of integers to be the TYPE_DOMAIN of an ARRAY_TYPE.
MAXVAL should be the maximum value in the domain
(one less than the length of the array).

The maximum value that MAXVAL can have is INT_MAX for a HOST_WIDE_INT.
We don't enforce this limit, that is up to caller (e.g. language front end).
The limit exists because the result is a signed type and we don't handle
sizes that use more than one HOST_WIDE_INT.

◆ force_fit_type()

We force the wide_int CST to the range of the type TYPE by sign or
zero extending it.  OVERFLOWABLE indicates if we are interested in
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_base_address()

tree get_base_address ( tree t)

The base address of a memory reference expression is the main

'array[i].fld[j]' is 'array'.  You can think of this as stripping
away the offset part from a memory address.

This function calls handled_component_p to strip away all the inner
parts of the memory reference until it reaches the base object.
