gdb-add-index — Add index files to speed up GDB


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".  Note that the index is never generated for files that do not contain DWARF debug information (sections named ".debug_*").

See more in the GDB manual in node "Index Files" -- shell command "info -f gdb -n 'Index Files'".

The full documentation for GDB is maintained as a Texinfo manual. If the "info" and "gdb" programs and GDB's Texinfo documentation are properly installed at your site, the command

        info gdb

should give you access to the complete manual.
