Detailed Description

Enumeration Type Documentation

Dwarf_Ranges_Entry_Type

enum Dwarf_Ranges_Entry_Type

The dwr_addr1/addr2 data is either an offset (DW_RANGES_ENTRY) or an address (dwr_addr2 in DW_RANGES_ADDRESS_SELECTION) or both are zero (DW_RANGES_END). For DWARF5 each table starts with a header followed by range list entries defined as here. Dwarf_Ranges* apply to DWARF2,3, and 4. Not to DWARF5 (the data is different and in a new DWARF5 section).

Dwarf_Form_Class

enum Dwarf_Form_Class

The dwarf specification separates FORMs into different classes. To do the separation properly requires 4 pieces of data as of DWARF4 (thus the function arguments listed here). The DWARF4 specification class definition suffices to describe all DWARF versions. See section 7.5.4, Attribute Encodings. A return of DW_FORM_CLASS_UNKNOWN means the library could not properly figure out what form-class it is.

DW_FORM_CLASS_FRAMEPTR is MIPS/IRIX only, and refers to the DW_AT_MIPS_fde attribute (a reference to the .debug_frame section).

DWARF5: DW_FORM_CLASS_LOCLISTSPTR is like DW_FORM_CLASS_LOCLIST except that LOCLISTSPTR is always a section offset, never an index, and LOCLISTSPTR is only referenced by DW_AT_loclists_base. Note DW_FORM_CLASS_LOCLISTSPTR spelling to distinguish from DW_FORM_CLASS_LOCLISTPTR.

DWARF5: DW_FORM_CLASS_RNGLISTSPTR is like DW_FORM_CLASS_RNGLIST except that RNGLISTSPTR is always a section offset, never an index. DW_FORM_CLASS_RNGLISTSPTR is only referenced by DW_AT_rnglists_base.
