gdb/gdb-gdb-add-index-script.patch
Michael Matz e7db4ec014 - Rebase to 8.1 release: 
* ptype/o prints offsets and sizes of members (like pahole)
  * tab-completion improved: quoting function names is not generally
    necessary anymore, completion offers for breakpoint don't include
    data symbol
  * enable/disable breakpoints now accept ranges: 'disable 1.3-5'
  * new commands:
    - set/show cwd: working directory of debuggee
    - set/show compile-gcc: program to use for 'compile' command
    - starti: start program and stop at first instruction
    - TUI single-key commands: 'i' for stepi and 'o' for nexti
  * --readnever option disables any reading of debug info (for dumping)
  * s390: guarded storage register access for z14
  * gcore option -a dumps all memory mapping
  * C++ breakpoints: 'b foo' will now set a breakpoint on all functions
    and methods named 'foo' no matter the scope.  Use -qualified if you
    don't want that
  * python scripting: new events gdb.new_inferior, gdb.inferior_deleted
    and gdb.new_thread; new command rbreak (breakpoint accepting regexps)
  * gdbserver can be passed environment parameters to remote debuggee

Subject: RFC: add DWARF index support
FileName: gdb-gdb-add-index-script.patch
;; Provide /usr/bin/gdb-add-index for rpm-build (Tom Tromey).
;;=push: Re-check against the upstream version.
http://sourceware.org/ml/gdb-patches/2010-07/msg00184.html
Jan Kratochvil: Fixed $d -> $dir.
Jan Kratochvil: Remove /dev/null redirection.

Tom> This patch series adds support for a DWARF index to gdb.
Roland suggested we wrap up the index-creation code into a helper
script.
I'm not sure if this is something people would want in gdb proper, but I
figured I would send it here just in case.

+gdb-add-index @var{filename}
+@c man end
+
+@c man begin DESCRIPTION gdb-add-index
+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
+@command{readelf -S filename}: the index is stored in a section named
+@code{.gdb_index}. Note that the index is never generated for files that do
+not contain DWARF debug information (sections named @code{.debug_*}).
