The gdb format mechanism doesn't currently support the 'z' size
modifier, there are a few places in GDB where this is used. Instead
of removing these uses lets just add support to GDB for using 'z'.
I found this issue when trying to use some of the debug output.
Before this commit:
(gdb) set debug dwarf-line 9
(gdb) file test
Reading symbols from test...
Unrecognized format specifier 'z' in printf
(No debugging symbols found in test)
(gdb)
After this commit:
(gdb) set debug dwarf-line 9
(gdb) file test
Reading symbols from test...
Adding dir 1: /usr/include
Adding file 1: test.c
Adding file 2: stdc-predef.h
Processing actual line 3: file 1, address 0x4004a0, is_stmt 1, discrim 0
Processing actual line 4: file 1, address 0x4004a0, is_stmt 1, discrim 0
.... lots of debug output ...
Processing actual line 10: file 1, address 0x4003b7, is_stmt 0, discrim 0
(gdb)
I've added a self test to cover the integer format size modifiers,
including the 'z' modifier.
gdb/ChangeLog:
* gdbsupport/format.c (format_pieces::format_pieces): Support
printf 'z' size modifier.
* gdbsupport/format.h (enum argclass): Add size_t_arg.
* printcmd.c (ui_printf): Handle size_t_arg.
* ui-out.c (ui_out::vmessage): Likewise.
* unittests/format_pieces-selftests.c (test_format_int_sizes): New
function.
(run_tests): Call test_format_int_sizes.
gdb/gdbserver/ChangeLog:
* ax.c (ax_printf): Handle size_t_arg.

This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.

This changes the printf command's %s and %ls formats to special-case
NULL, and print "(null)" for these. This is PR cli/14977. This
behavior seems a bit friendlier; I was undecided on whether other
invalid pointers should be handled specially somehow, so for the time
being I've left those out.

This replaces parse_format_string with a class, removing some
constructors along the way. While doing this, I found that one
argument to gen_printf is unused, so I removed it.
Also, I am not completely sure, but the use of `release' in
maint_agent_printf_command and parse_cmd_to_aexpr seems like it may
leak expressions.
Regression tested by the buildbot.

Most allocation functions (if not all) return a void* pointing to the
allocated memory. In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).
The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++". I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style. I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.
Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.
Only files built on x86 with --enable-targets=all are modified. This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers. Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.
I built-tested this with --enable-targets=all and reg-tested.
Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script. I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

Hi,
I see the following build warning with recent GCC built from mainline,
aarch64-none-linux-gnu-gcc -g -O2 -I. -I/home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver -I/home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/../common -I/home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/../regformats -I/home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/.. -I/home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/../../include -I/home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/../gnulib/import -Ibuild-gnulib-gdbserver/import -Wall -Wpointer-arith -Wformat-nonliteral -Wno-char-subscripts -Wempty-body -Wdeclaration-after-statement -Werror -DGDBSERVER -DCONFIG_UST_GDB_INTEGRATION -fPIC -DIN_PROCESS_AGENT -fvisibility=hidden -c -o ax-ipa.o -MT ax-ipa.o -MMD -MP -MF .deps/ax-ipa.Tpo `echo " -Wall -Wpointer-arith -Wformat-nonliteral -Wno-char-subscripts -Wempty-body -Wdeclaration-after-statement " | sed "s/ -Wformat-nonliteral / -Wno-format-nonliteral /g"` /home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/ax.c
/home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/ax.c:73:28: error: 'gdb_agent_op_sizes' defined but not used [-Werror=unused-const-variable]
static const unsigned char gdb_agent_op_sizes [gdb_agent_op_last] =
^
cc1: all warnings being treated as errors
gdb_agent_op_sizes is only used in function is_goto_target, which is
defined inside #ifndef IN_PROCESS_AGENT. This warning is not arch
specific, so GCC mainline for other targets should produce this warning
too, although this warning is triggered by enabling aarch64 fast
tracepoint. The fix is to move gdb_agent_op_sizes to
gdb/gdbserver:
2015-09-21 Yao Qi <yao.qi@linaro.org>
* ax.c [!IN_PROCESS_AGENT] (gdb_agent_op_sizes): Define it.

This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

If GDB decides to change the breakpoint's conditions or commands,
it'll reinsert the same breakpoint again, with the new options
attached, without deleting the previous breakpoint. E.g.,
(gdb) set breakpoint always-inserted on
(gdb) b main if 0
Breakpoint 1 at 0x400594: file foo.c, line 21.
Sending packet: $Z0,400594,1;X3,220027#68...Packet received: OK
(gdb) b main
Breakpoint 15 at 0x400594: file foo.c, line 21.
Sending packet: $Z0,400594,1#49...Packet received: OK
GDBserver understands this and deletes the breakpoint's previous
conditions. But, it forgets to delete the previous commands.

This moves various low-level remote serial protocol bits into
common/rsp-low.[ch].
This is as close to a pure move as possible. There are some
redundancies remaining but those will be dealt with in a subsequent
patch.
Note that the two variants of remote_escape_output disagreed on the
treatment of "*". On the theory that quoting cannot hurt but the
absence possibly can, I chose the gdbserver variant to be the
canonical one.

This patch makes GDBserver support multi-process + biarch.
Currently, if you're debugging more than one process at once with a
single gdbserver (in extended-remote mode), then all processes must
have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you
see this:

... etc, etc ...
Even though the process was running a 32-bit program, GDBserver sent
back to GDB a register set in 64-bit layout.
A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a
while ago made GDB track a target_gdbarch per inferior, and as
consequence, fetch a target description per-inferior. This patch is
the GDBserver counterpart, that makes GDBserver keep track of each
process'es XML target description and register layout. So in the
example above, GDBserver will send the correct register set in 32-bit
layout to GDB.
A new "struct target_desc" object (tdesc for short) is added, that
holds the target description and register layout information about
each process. Each `struct process_info' holds a pointer to a target
description. The regcache also gains a pointer to a target
description, mainly for convenience, and parallel with GDB (and
possible future support for programs that flip processor modes).
The low target's arch_setup routines are responsible for setting the
process'es correct tdesc. This isn't that much different to how
things were done before, except that instead of detecting the inferior
process'es architecture and calling the corresponding
init_registers_FOO routine, which would change the regcache layout
globals and recreate the threads' regcaches, the regcache.c globals
are gone, and the init_registers_$BAR routines now each initialize a
separate global struct target_desc object (one for each arch variant
GDBserver supports), and so all the init_registers_$BAR routines that
are built into GDBserver are called early at GDBserver startup time
(similarly to how GDB handles its built-in target descriptions), and
then the arch_setup routine is responsible for making
process_info->tdesc point to one of these target description globals.
The regcache module is all parameterized to get the regcache's layout
from the tdesc object instead of the old register_bytes, etc. globals.
The threads' regcaches are now created lazily. The old scheme where
we created each of them when we added a new thread doesn't work
anymore, because we add the main thread/lwp before we see it stop for
the first time, and it is only when we see the thread stop for the
first time that we have a chance of determining the inferior's
architecture (through the_low_target.arch_setup). Therefore when we
add the main thread we don't know which architecture/tdesc its
regcache should have.
This patch makes the gdb.multi/multi-arch.exp test now pass against
(extended-remote) GDBserver. It currently fails, without this patch.
The IPA also uses the regcache, so it gains a new global struct
target_desc pointer, which points at the description of the process it
is loaded in.
Re. the linux-low.c & friends changes. Since the register map
etc. may differ between processes (64-bit vs 32-bit) etc., the
linux_target_ops num_regs, regmap and regset_bitmap data fields are no
longer sufficient. A new method is added in their place that returns
a pointer to a new struct that includes all info linux-low.c needs to
access registers of the current inferior.
The patch/discussion that originally introduced
linux-low.c:disabled_regsets mentions that the disabled_regsets set
may be different per mode (in a biarch setup), and indeed that is
cleared whenever we start a new (first) inferior, so that global is
moved as well behind the new `struct regs_info'.
On the x86 side:
I simply replaced the i387-fp.c:num_xmm_registers global with a check
for 64-bit or 32-bit process, which is equivalent to how the global
was set. This avoided coming up with some more general mechanism that
would work for all targets that use this module (GNU/Linux, Windows,
etc.).
