NAME         top

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

SYNOPSIS         top

       gdb-add-index filename

DESCRIPTION         top

       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.

       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.
