NAME

6       gdb-add-index - Add index files to speed up GDB
7

SYNOPSIS

9       gdb-add-index filename
10

DESCRIPTION

12       When GDB finds a symbol file, it scans the symbols in the file in order
13       to construct an internal symbol table.  This lets most GDB operations
14       work quickly--at the cost of a delay early on.  For large programs,
15       this delay can be quite lengthy, so GDB provides a way to build an
16       index, which speeds up startup.
17
18       To determine whether a file contains such an index, use the command
19       "readelf -S filename": the index is stored in a section named
20       ".gdb_index".  The index file can only be produced on systems which use
21       ELF binaries and DWARF debug information (i.e., sections named
22       ".debug_*").
23
24       gdb-add-index uses GDB and objdump found in the PATH environment
25       variable.  If you want to use different versions of these programs, you
26       can specify them through the GDB and OBJDUMP environment variables.
27
28       See more in the GDB manual in node "Index Files" -- shell command "info
29       -f gdb -n "Index Files"".

33       The full documentation for GDB is maintained as a Texinfo manual.  If
34       the "info" and "gdb" programs and GDB's Texinfo documentation are
35       properly installed at your site, the command
36
37               info gdb
38
39       should give you access to the complete manual.
