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". 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.
