0df0a2725c Fix 308644 vgdb command for having the info for the track-fds option
(allows to have the list of opened fds and the associated info
on request from GDB or from the shell, using vgdb)

2478728636 gdbserver: introduce support to show the AVX registers.
This implies to change the interface between the
arch independent gdbserver files and the arch dependent files
as AVX implies a choice of xml files at run time.

In valgrind-low-amd64.c, the xml files and the nr of registers
are different depending on AVX support or not.

Other platforms still have a fully static nr of registers.

4e5a6025dd Prepare for AVX support : restructure gdbsrv/target/valgrind-low/arch low
AVX support implies to have target xml files which are selected
according to the machine hwcaps.
This change improves the structure of the gdbserver software layering
to prepare for this.

Basically, the protocol files (e.g. server.c) are now calling directly
the valgrind target operations which are now defined in target.h/target.c
(before, there was a level of indirection inheritated from the GDB
structure which was useless for valgrind gdbserver).
+ clarified some comments

f53053e7c9 add optional arg [aspacemgr] to v.info memory to show aspacemgr segments.
When investigating Valgrind out of memory situation,
it is useful to be able to output the list of segments of the
aspacemgr at any moment.
The GDB monitor command "v.info memory" has now an optional
argument allowing to output this list of segments

323ba3d8f0 Fix bug 297078 gdbserver signal handling problems caused by diff vki nr/gdb nr and
non reset of "C-ontinued" signal

* To allow vki signame to be used in debuglog:
  - pub_core_signals.h : added prototype for Char *VG_(signame)
  - m_signals.c : changed static const Char *signame(Int sigNo)
                      to const Char *VG_(signame)(Int sigNo)

* valgrind-low.c : when the signal to report to gdb has
  been reported, clear it so that it is not reported anymore
  afterwards.

* m_gdbserver.c: when checking in pass_signals if signal
  can be passed without gdb interaction, do a conversion
  from vki nr to gdb nr when indexing
  (as pass_signals[] is indexed by gdb_nr).

* various gdbserver files:
  - used vki_ prefix for some args and variables to clarify
  - better debuglog tracing

* modified nlpasssigalrm.vgtest to test SIGCHLD signal
  handling followed by a break (to see SIGTRAP is properly
  given to gdb).

0eb5c19d3f After a fork, gdbserver_init can be called again.
Buffers should not be re-allocated in such a case.

b66672b48f * compare vgdb-error with n_errs_shown, not with n_errs_found.
Using n_errs_shown allows the user to stop on an error
  identified in a previous run by counting errors shown.
* shows also n_errs_shown in monitor command v.info n_errs_found
* slightly clarified the manual, updated to new output of v.info n_errs_found

d8a36cfde4 gdbsrv: factorize gdb version handling, fix doc and typos
* fix various typos in doc
* following commit in gdb
   http://sourceware.org/ml/gdb-patches/2011-07/msg00742.html
  means unlimited length for valgrind watchpoints is understood by the
  (future) gdb 7.4 => doc updated
* factorize  gdb version detection and reporting in
  gdbserver_tests/make_local_links
* replace zignal by signal in a string used in umsg.
* updated gdbserver_tests/README_DEVELOPPERS (ref to --port vgdb option)

No functional change, tested on f12/x86, debian5/amd64, s390/RHEL4

Fixes #278892.  (Philippe Waroquiers, philippe.waroquiers@skynet.be)

a07f759681 Addition of v.info scheduler monitor command
Monitor command useful for debugging/investigation of Valgrind unwinder and/or
gdbserver/gdb stack trace.

The Valgrind unwinder has some limitations compared to the GDB unwinder.
(see e.g. 278972).

With this monitor command, it is easy to see if the Valgrind unwinder
produces something different than the GDB unwinder.

Fixes #279212.  (Philippe Waroquiers, philippe.waroquiers@skynet.be)

97c113e7e0 valgrind and tool mon. cmds prefixes changes + doc fixes + new vgdb option
--cmd-time-out

* changed prefixes of Valgrind core monitor commands from vg. to v.
* removed prefixes of Tool monitor commands
* memcheck leak_check 'leakpossible' arg renamed to 'possibleleak'
* memcheck make_memory 'ifaddressabledefined' arg renamed to
'Definedifaddressable'
    (with uppercase D to avoid confusion with 'defined' arg).
* vgdb options
  - Some doc updates : more logical option order documentation,
       specify 'standalone' for options aimed at standalone usage.
  - added option --cmd-time-out for standalone vgdb
     (comment of Josef Weindendorfer, needed to interface with a callgrind GUI)
* updated tests according to the above.
* updated documentation according to the above.
* some additional minor doc fixes/clarifications

4c205c2b43 gdbserver: Fixes for ARM-Thumb (#214909 c 76)
fix arm thumb by transforming an address to its thumb form when needed

* added a function thumb_pc transforming a pc to its thumb form if needed
  (using an heuristic to guess if this is a thumb address)
* when program counter is modified by gdb, use thumb_pc
* use thumb_pc in monitor command vg.translate

(I was able to check that this improves inferior call on a small
thumb compiled executable + mcinfcallRU test) but I could not compile
all tests with thumb).
