DESCRIPTION
When expanding a partial symbol table entry to a full symbol table
entry, this is the function that gets called to read in the symbols
- for the compilation unit.
-
- Returns a pointer to the newly constructed symtab (which is now
- the new first one on the objfile's symtab list).
+ for the compilation unit. A pointer to the newly constructed symtab,
+ which is now the new first one on the objfile's symtab list, is
+ stashed in the partial symbol table entry.
