46 /* This file declares various DWARF-related constants using a set of
47 macros which can be redefined by the including file.
49 The macros are in sections. Each section corresponds to a single
50 set of DWARF constants and has a corresponding key. The key is
51 used in all the macro names.
53 The sections are TAG (for DW_TAG_ constants), FORM (DW_FORM_), AT
54 (DW_AT_), OP (DW_OP_), ATE (DW_ATE_), and CFA (DW_CFA_).
56 Using TAG as an example, the following macros may be used for each
57 key:
59 DW_FIRST_TAG(name, value) - Introduce the first DW_TAG constant.
61 DW_TAG(name, value) - Define a subsequent constant.
63 DW_TAG_DUP(name, value) - Define a subsequent constant whose value
64 is a duplicate of some other constant. Not all keys use the _DUP
65 macro form. If more than one name shares a value, then the base
66 (DW_TAG) form will be the preferred name and DW_TAG_DUP will hold
67 any alternate names.
69 DW_END_TAG - Invoked at the end of the DW_TAG constants. */
