OSI->object_size_type).
|
|
|
|
For allocation CALL_EXPR like malloc or calloc object size is the size
|
|
|
|
of the allocation.
|
|
|
|
For pointer PLUS_EXPR where second operand is a constant integer,
|
|
|
|
object size is object size of the first operand minus the constant.
|
|
|
|
If the constant is bigger than the number of remaining bytes until the
|
|
|
|
end of the object, object size is 0, but if it is instead a pointer
|
|
|
|
subtraction, object size is unknown[object_size_type].
|
|
|
|
To differentiate addition from subtraction, ADDR_EXPR returns
|
|
|
|
unknown[object_size_type] for all objects bigger than half of the address
|
|
|
|
space, and constants less than half of the address space are considered
|
|
|
|
addition, while bigger constants subtraction.
|
|
|
|
For a memcpy like CALL_EXPR that always returns one of its arguments, the
|
|
|
|
object size is object size of that argument.
|
|
|
|
Otherwise, object size is the maximum of object sizes of variables
|
|
|
|
that it might be set to. */
