11 Roland suggested we wrap up the index-creation code into a helper
14 I'm not sure if this is something people would want in gdb proper, but I
15 figured I would send it here just in case.

112 +gdb-add-index @var{filename}
115 +@c man begin DESCRIPTION gdb-add-index
116 +When GDB finds a symbol file, it scans the symbols in the file in order
117 +to construct an internal symbol table. This lets most GDB operations
118 +work quickly--at the cost of a delay early on. For large programs,
119 +this delay can be quite lengthy, so GDB provides a way to build an
120 +index, which speeds up startup.
122 +To determine whether a file contains such an index, use the command
123 +@command{readelf -S filename}: the index is stored in a section named
124 +@code{.gdb_index}. Note that the index is never generated for files that do
125 +not contain DWARF debug information (sections named @code{.debug_*}).
