gdb-add-index — Add index files to speed up GDB
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". Note that the index is never generated for files that do not contain DWARF debug information (sections named

"Index Files" -- shell command
"info -f gdb -n 'Index Files'".
The full documentation for GDB is maintained as a Texinfo manual. If the
"gdb" programs and GDB's Texinfo documentation are properly installed at your site, the command
should give you access to the complete manual.
