I don't know much about s390, but from reading the code I believe the
right fix is to treat d2 as signed.

gdb/
2013-04-19  Pedro Alves  <palves@redhat.com>

* s390-tdep.c (is_rs, is_rsy, is_rx, is_rxy): Change type of 'd2'
parameter to int *.

ppc-linux-tdep.c: Wrong signness for buffer holding instructions.

There seems to be no reason for this buffer to be signed.  We pass it
around to functions expecting it to be unsigned (which triggers
-Wpointer-sign warnings).

gdb/
2013-04-19  Pedro Alves  <palves@redhat.com>

* ppc-linux-tdep.c (ppc_skip_trampoline_code): Change local
'insnbuf' buffer type to unsigned int[].

mips-tdep.c: Wrong signness for local holding PC register.

Addresses on MIPS are signed, and we're indeed using
regcache_cooked_read_signed to read the PC, but, we're passing it the
address of an unsigned variable, which triggers a -Wpointer-sign
warning.  I've chosen to change the variable's type.  I believe this
will end up being the same (though I can't test it).

alpha-tdep.c/mips-tdep.c: "set heuristic-fence-post" is signed/zinteger.

These commands are currently var_zinteger, hence their control
variable is signed.

gdb/
2013-04-19  Pedro Alves  <palves@redhat.com>

* alpha-tdep.c (heuristic_fence_post): Change type to int.

UINT_MAX.
* mips-tdep.c (heuristic_fence_post): Change type to int.
(heuristic_proc_start): Adjust to check -1 instead of UINT_MAX.

cris-tdep.c: Use unsigned variable for unsigned command.

"set cris-version" is an unsigned command:

    /* CRIS-specific user-commands.  */
    add_setshow_uinteger_cmd ("cris-version", class_support,
       &usr_cmd_cris_version,
       _("Set the current CRIS version."),
       _("Show the current CRIS version."),
       _("\
  Set to 10 for CRISv10 or 32 for CRISv32 if autodetection fails.\n\
  Defaults to 10. "),

Tested by building on x86_64 Fedora 17.

2013-04-19  Pedro Alves  <palves@redhat.com>

* cris-tdep.c (usr_cmd_cris_version): Make unsigned.

-Wpointer-sign: gdb_byte -> char.

This is sort of the opposite of the previous patch.  Places that
manipulate strings or interfaces that return strings are changed to
use char* instead of gdb_byte*.

Adjust.
(info_spu_event_command, info_spu_signal_command): Add casts to

-Wpointer-sign: char -> gdb_byte.

-Wpointer-sign catches all these cases across the codebase that should
be using gdb_byte for raw target bytes.  I think these are all
obvious, hence I've collapsed into a single patch.

Fix the x87 FP register printout when issuing the “info float” command.

Consider the following simple program:

.globl  _start
.text
_start:
      fldt    val
.data
      val: .byte 0x00,0x00,0x45,0x07,0x11,0x19,0x22,0xe9,0xfe,0xbf

With current GDB on x86-64 GNU/Linux hosts, after the moment the fldt
command has been executed the register st(0) looks like this,
according to the “info regs” output (TOP=7):

  R7: Valid   0xffffffbffffffffeffffffe922191107450000 -0.910676542908976927

which is clearly wrong (just count its length).  The problem is due to
the printf statement (see patch) printing a promoted integer value of
a char argument "raw[i]", and, since char is signed on x86-64
GNU/Linux, the erroneous “ffffff” are printed for the first three
bytes which turn out to be "negative".  The fix is to use gdb_byte
instead which is unsigned (and is the type of value_contents(), the
type to be used for raw target bytes anyway).  After the fix the value
will be printed correctly:

  R7: Valid   0xbffee922191107450000 -0.910676542908976927

* linux-low.h (struct lwp_info) <thread_known>: Move under

Fix remaining GDBserver issues with !HAVE_THREAD_DB_H.

The previous patches are still not sufficient to build gdbserver with

make: *** [thread-db.o] Error 1

First, linux-low.h is including <thread_db.h> directly instead of our
gdb_thread_db.h, although thread-db.c includes the latter.  Then the
'th' field of struct lwp_info is only defined if HAVE_THREAD_DB_H is
defined, which is not true if we're using our replacement copy of
thread_db.h.  We have a USE_THREAD_DB symbol defined if we're building
thread-db.c that's ideal for this, however, it's currently only
defined when compiling linux-low.c (through a Makefile rule).  The
patch makes it defined when compiling any file.

../../../src/gdb/gdbserver/../common/glibc_thread_db.h:270:3: error: unknown type name ‘intptr_t’

We used to have a workaround for this, but the patch to import
gnulib's stdint.h removed it:

  http://www.sourceware.org/ml/gdb-patches/2008-06/msg00050.html

and defs.h made to always include stdint.h.  However, gdbserver
doesn't include stdint.h in its equivalent server.h.

Rather than working around the issue, I've imported a more recent
version from glibc, which itself includes <stdint.h>.  Other than
copyright years and FSF snail mail address, the file hasn't been
touched since 2003 in glibc.  AFAICS, our version was updated last in
2000-09-03.

A note on the apparent license change: before the previous patch, this
file's contents were part of gdb_thread_db.h, and we can see that its
license's text was changed in this patch
<http://sourceware.org/ml/gdb-patches/2009-03/msg00251.html>.  That
was certainly just an easy to overlook grep/sed mistake that fell
through the cracks.

(git 568035b7874a099087b77f7bba3e36a1173787b0).

Move fallback thread_db.h to a separate file.

Having this on a separate file makes it easier to import a new version
-- one can just copy over instead of having to care about preserving
the GDB-specific bits.

PR build/11881: LIBTHREAD_DB_SO can be undefined.

This patch:

 http://sourceware.org/ml/gdb-patches/2009-04/msg00115.html

Changed behaviour by only defining LIBTHREAD_DB_SO if thread_db.h exists. The
definition of LIBTHREAD_DB_SO and LIBTHREAD_DB_SEARCH_PATH should be moved
outside of #ifdef HAVE_THREAD_DB_H.

This is based on a patch attached to the PR, however, it needed a
tweak, as it was it broke the HAVE_THREAD_DB_H path.

warning workaround.

Accept "set foo unlimited" in integer/uinteger/zuinteger_unlimited commands.

Currently, several commands take "0" or "-1" to mean "unlimited".

"show" knows when to print "unlimited":

 (gdb) show height
 Number of lines gdb thinks are in a page is 45.
 (gdb) set height 0
 (gdb) show height
 Number of lines gdb thinks are in a page is unlimited.

However, the user can't herself specify "unlimited" directly:

 (gdb) set height unlimited
 No symbol table is loaded.  Use the "file" command.
 (gdb)

This patch addresses that, by adjusting the set handler for all
integer/uinteger/zuinteger_unlimited commands to accept literal
"unlimited".  It also installs a completer.  Presently, we complete on
symbols by default, and at
<http://sourceware.org/ml/gdb-patches/2013-03/msg00864.html> I've
shown a WIP prototype that tried to keep that half working in these
commands.  In the end, it turned out to be more complicated than
justifiable, IMO.  It's super rare to want to pass the value of a
variable/symbol in the program to a GDB set/show knob.  That'll still
work, it's just that we won't assist with completion anymore.  This
patch just sticks with the simple, and completes on "unlimited", and
nothing else.  This simplification means that

  "set he<tab><tab>"

is all it takes to get to:

  "set height unlimited"

The patch then goes through all integer/uinteger/zuinteger_unlimited
commands in the tree, and updates both the online help and the manual
to mention that "unlimited" is accepted in addition to 0/-1.  In the
cases where the command had no online help text at all, this adds it.
I've tried to make the texts read in a way that "unlimited" is
suggested before "0" or "-1" is.

Tested on x86_64 Fedora 17.

make -gdb-exit call disconnect_tracing too, and don't lose history if the target errors on "quit"

Gareth mentions in PR gdb/15275:

 "The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing()
 and therefore exits correctly."

It should, so to get out of tfind mode, as quit may detach instead of
kill, and we don't want to confuse the memory/register accesses
etc. of the detach process.  So we should push down the disconnect
tracing bits at least to quit_force.  But we can't as is, as that
would swallow the error thrown by answering "no" to:

  Trace is running but will stop on detach; detach anyway? (y or n)

So to address that, we split disconnect_tracing in two.  One part that
does the query, and another part that does the rest, and we make
quit_force call the latter.

Looking at quit_force, it does several things, some of which are a bit
independent of the others.  It first kills/detaches, and then writes
history, and then runs the final cleanups.  It seems better to me to
do each of these things even if the previous thing throws.  E.g., as
is, if something throws while detaching, then we skip writing history.

Tested on x86_64 Fedora 17.
