 gdb-add-index
 =============
 
 gdb-add-index FILENAME
 
    When GDB finds a symbol file, it scans the symbols in the file in
 order to construct an internal symbol table.  This lets most GDB
 operations work quickly-at the cost of a delay early on.  For large
 programs, this delay can be quite lengthy, so GDB provides a way to
 build an index, which speeds up startup.
 
    To determine whether a file contains such an index, use the command
 'readelf -S filename': the index is stored in a section named
 '.gdb_index'.  The index file can only be produced on systems which use
 ELF binaries and DWARF debug information (i.e., sections named
 '.debug_*').
 
    'gdb-add-index' uses GDB and 'objdump' found in the 'PATH'
 environment variable.  If you want to use different versions of these
 programs, you can specify them through the 'GDB' and 'OBJDUMP'
 environment variables.
