Subject: [RFA 2/7] API for inhibiting section map updates
http://sourceware.org/ml/gdb-cvs/2013-06/msg00013.html
--bPg9NdpM9EETxvqt
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
This patch adds a couple of functions to allow section map updates
to be temporarily inhibited. Without this ability, the calls to
evaluate_probe_argument in svr4_handle_solib_event trigger a section
map update every time a group of shared objects are mapped, which
significantly affects performance. The updates are unnecessary in
this case as the sections in question are in the runtime linker and
so already in the section map.

This patch updates gdbserver to allow arguments to be passed in the
annex of qXfer:libraries-svr4:read to allow that function to transfer
partial lists of libraries. The ability of gdbserver to support
these arguments is indicated by a qSupported response containing
"augmented-libraries-svr4-read+".

Subject: [RFA 5/7] Improved linker-debugger interface
--qse+WBH4guesipZ+
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
This patch implements the probes-based runtime linker interface.
It works as follows:
- On inferior startup, GDB searches the dynamic linker for a
number of named probes.
- If all probes are found, GDB sets a breakpoint on each one.
Otherwise, the standard function _dl_debug_state is used.
- When using probes, a per-pspace list is maintained of all
libraries currently loaded by the inferior. It's updated
as necessary every time a solib event stop occurs.
- When using probes, svr4_current_sos will return a copy of
the cached list. When not using probes the entire list
will be fetched from the inferior as before.
- If any error occurs, GDB will print a warning and revert to
the standard interface.

Subject: [RFA 6/7] Linker-debugger interface tests by Jan

This patch updates the testsuite to cope with some changes resulting
from the probes-based interface, and adds a new test. This patch is
principally the work of Jan Kratochvil.

* lib/gdb.exp (build_executable_from_specs): Use gdb_compile_pthread,
gdb_compile_shlib or gdb_compile_shlib_pthreads where appropriate.
* lib/prelink-support.exp (build_executable_own_libs): Allow INTERP
to be set to "no" to indicate that no ld.so copy should be made.
* gdb.base/break-interp.exp (solib_bp): New constant.
