[Bug symtab/12302] New: incomplete address table in .gdb_index section

           Summary: incomplete address table in .gdb_index section
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab
        AssignedTo: unassigned@sourceware.org
        ReportedBy: dje@google.com


The "save gdb-index" command creates a .gdb-index file that contains an
optimized version of the debug info to speed up start up when debugging large
programs.
The address table part of this file is incomplete.
gdb uses the textlow,texthigh values of each partial symtab to populate this
table, but this is insufficient,
there may be multiple noncontiguous regions.
