356 DWARF defines composite location descriptions that can have one or more parts.
358 The following operation expression creates a composite location description.

430 However, DW_OP_plus cannot be used to offset a composite location. It only
433 
435 To offset a composite location description, the compiler would need to make a
436 different composite location description, starting at the part corresponding to
464 CFI location expressions do not allow composite locations or non-global address
485 composite location descriptions.
501 - For composite, it is a linear stream of bytes defined by the composite's parts.
532 To allow incremental and nested creation of composite location descriptions, a
534 composite. Currently, creating a composite must always be the last operation of
538 location description. Currently this is only possible as a piece of a composite
609 has to occupy two vector registers. A composite location description is created
647 The DW_OP_piece either creates a new composite location description, or adds a
650 composite location description, otherwise it creates a new incomplete composite
651 location description with no parts. Finally it pushes the incomplete composite
655 composite location description. The 4 of the DW_OP_piece specifies the size of
660 an incomplete composite, an undefined location description is used for the part.
668 DW_OP_piece is evaluated there is an incomplete composite on the stack. So the
684 composite location description, it is converted to a complete location

810 locations in parts of composite locations.
813 is now possible for parts of a composite to involve locations in different
865 spaces, or even a composite of different location kinds.
881 address space, be described by a composite location description, or could even
914 For example, a DW_OP_extend operation could create a composite location
916 count. The resulting composite would effectively be a vector of element count
920 A DW_OP_select_bit_piece operation could create a composite location description
922 resulting composite would effectively be a vector of elements, selecting from
934 composite location description out of two location descriptions, an offset
935 value, and a size. The resulting composite would consist of parts that are

2587 A composite location storage represents an object or value which may be
2598 A composite location storage can have zero or more parts. The parts are
2600 each part with no gaps between them. Therefore, the size of a composite location
2606 A composite location description specifies a composite location storage. The bit
2607 offset corresponds to a bit position within the composite location storage.
2609 There are operations that create a composite location storage.
2611 There are other operations that allow a composite location storage to be
2613 be one or more operations to create the final composite location storage. A
2614 series of such operations describes the parts of the composite location storage
2617 To support incremental creation, a composite location storage can be in an
2619 composite location storage, it adds a new part.
2621 A composite location description that specifies a composite location storage
2622 that is incomplete is termed an incomplete composite location description. A
2623 composite location description that specifies a composite location storage that
2624 is complete is termed a complete composite location description.
2627 composite location description SL after the execution of an operation expression
2628 has completed, SL is converted to a complete composite location description.
