gdb-add-index: Add index files to speed up GDB
gdb-add-index - Add index files to speed up GDB
DESCRIPTIONWhen 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_*").
