-DESCRIPTION
+ DESCRIPTION
- This is the top level dwarf parsing routine for building partial

-
- It scans from the beginning of the DWARF table looking for the first
- TAG_compile_unit DIE, and then follows the sibling chain to locate
- each additional TAG_compile_unit DIE.
-
- For each TAG_compile_unit DIE it creates a partial symtab structure,
- calls a subordinate routine to collect all the compilation unit's
- global DIE's, file scope DIEs, typedef DIEs, etc, and then links the
- new partial symtab structure into the partial symbol table. It also
- records the appropriate information in the partial symbol table entry
- to allow the chunk of DIE's and line number table for this compilation
- unit to be located and re-read later, to generate a complete symbol
- table entry for the compilation unit.
-
- Thus it effectively partitions up a chunk of DIE's for multiple
- compilation units into smaller DIE chunks and line number tables,
- and associates them with a partial symbol table entry.
