John Baldwin 036e657b48 Do not use std::move when assigning an anonymous object to a unique_ptr.
Using std::move forces an extra copy of the object.  These changes fix
-Wpessimizing-move warnings from clang.

Now that we require C++11, use std::unique_ptr and std::move directly.

Pedro Alves 4d01a485d2 'struct expression *' -> gdb::unique_xmalloc_ptr<expression>
This patch makes parse_expression and friends return a unique_ptr
instead of raw pointer [1]:

  typedef gdb::unique_malloc_ptr<expression> expression_up;

and then adjusts the codebase throughout to stop using cleanups to
manage lifetime of expression pointers.

Whenever I found a structure owning an expression pointer, I made it
store a unique_ptr instead of a raw pointer, which then requires using
new/delete of the holding structure, instead of XNEW/xfree.

[1] - I'd like to set the rule that types named with an "_up" suffix
      are unique_ptr typedefs.

Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply
because we still use xmalloc instead of new to allocate expression
objects.  Once that's changed, all we need to do is change the
expression_up typedef and the smart pointer will then call delete
instead of xfree.

Simon Marchi 8d7493201c Replace some xmalloc-family functions with XNEW-family ones
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.

Joel Brobecker 47e9c225c1 ignore invalid DOF provider sections
On x86-solaris 10, we noticed that starting a program would sometimes
cause the debugger to crash. For instance:

    % gdb a
    (gdb) break adainit
    Breakpoint 1 at 0x8051f03
    (gdb) run
    Starting program: /[...]/a
    [Thread debugging using libthread_db enabled]
    zsh: 24398 segmentation fault (core dumped)  /[...]/gdb a

The exception occurs in dtrace_process_dof_probe, while trying
to process each probe referenced by a DTRACE_DOF_SECT_TYPE_PROVIDER
DOF section from /lib/libc.so.1. For reference, the ELF section
in that shared library providing the DOF data has the following
characteristics:

    Idx Name          Size      VMA       LMA       File off  Algn
     14 .SUNW_dof     0000109d  000b4398  000b4398  000b4398  2**3
                      CONTENTS, ALLOC, LOAD, READONLY, DATA

The function dtrace_process_dof gets passed the contents of that
ELF section, which allows it to determine the location of the table
where all DOF sections are described. I dumped the contents of
each DOF section as seen by GDB, and it seemed to be plausible,
because the offset of each DOF section was pretty much equal to
the sum of the offset and size of the previous DOF section. Also,
the offset + sum of the last section corresponds to the size of
the .SUNW_dof section.

Things start to break down when processing one of the DOF sections
that has a type of DTRACE_DOF_SECT_TYPE_PROVIDER. It gets the contents
of this DOF section via:

        struct dtrace_dof_provider *provider = (struct dtrace_dof_provider *)
          DTRACE_DOF_PTR (dof, DOF_UINT (dof, section->dofs_offset));

Said more simply, the struct dtrace_dof_provider data is at
section->dofs_offset of the entire DOF contents. Given that
the contents of SECTION seemed to make sense, so far so good.

However, what SECTION tells us is that our DOF provider section
is 40 bytes long:

    (gdb) print *section
    $36 = {dofs_type = 15, dofs_align = 4, dofs_flags = 1,
           dofs_entsize = 0, dofs_offset = 3264, dofs_size = 40}
                                                 ^^^^^^^^^^^^^^

But on the other hand:

    (gdb) p sizeof (struct dtrace_dof_provider)
    $54 = 44

In other words GDB expected a bigger DOF section and when we try to
fetch the value of the last field of that DOF section (dofpv_prenoffs)...

    eoffsets_s = DTRACE_DOF_SECT (dof,
                                  DOF_UINT (dof, provider->dofpv_prenoffs));

... we end up reading data that actually belongs to another DOF
section, and therefore irrelevant. This in turn means that the value
of eofftab gets incorrectly set, since it depends on eoffsets_s:

    eofftab = DTRACE_DOF_PTR (dof, DOF_UINT (dof, eoffsets_s->dofs_offset));

This invalid address quickly catches up to us when we pass it to
dtrace_process_dof_probe shortly after, where we crash because
we try to subscript it:

    Program received signal SIGSEGV, Segmentation fault.
    0x08155bba in dtrace_process_dof_probe ([...]) at [...]/dtrace-probe.c:378
    378             = ((uint32_t *) eofftab)[...];

This patch fixes the issue by detecting provider DOF sections
that are smaller than expected, and discarding the DOF data.

gdb/ChangeLog:

        * dtrace-probe.c (dtrace_process_dof): Ignore the objfile's DOF
        data if a DTRACE_DOF_SECT_TYPE_PROVIDER section is found to be
        smaller than expected.

Joel Brobecker 79498702ef Initialize EXPR in dtrace-probe::dtrace_process_dof_probe
GCC 4.4.7 generates the following warning:

 | cc1: warnings being treated as errors
 | dtrace-probe.c: In function ‘dtrace_process_dof_probe’:
 | dtrace-probe.c:416: error: ‘expr’ may be used uninitialized in this function
 | make[2]: *** [dtrace-probe.o] Error 1

Later versions (GCC 5) do a better job and don't generate the warning,
but it does not hurt to pre-initialize "expr" to NULL.

gdb/ChangeLog:

        * dtrace-probe.c (dtrace_process_dof_probe): Initialize expr to NULL.
2015-03-27 08:25:28 -07:00
Joel Brobecker 429e1e811b dtrace-probe: Handle error while parsing probe argument.
The debugger on Solaris has been broken since the introduction of
DTrace probe support:

    (gdb) start
    Temporary breakpoint 1 at 0x80593bc: file simple_main.adb, line 4.
    Starting program: /[...]/simple_main
    [Thread debugging using libthread_db enabled]
    No definition of "mutex_t" in current context.

The problem occurs while trying to parse a probe's argument,
and the exception propagates all the way to the top. This patch
fixes the issue by containing the exception and falling back on
using the "long" builtin type if the argument's type could not
be determined.

Also, the parsing should be done using the C language parser.

gdb/ChangeLog:

        * dtrace-probe.c (dtrace_process_dof_probe): Contain any
        exception raised while parsing the probe arguments.
        Force parsing to be done using the C language parser.
        * expression.h (parse_expression_with_language): Declare.

Pedro Alves bf36a1e7df More redefinition errors in C++ mode
In C++, we can't forward declare objects like in C.  The compiler
complains about symbol redefinition.  Most cases of this were fixed in
e36122e9, but dtrace probes introduced a new one meanwhile.  This
patch fixes it the same way e36122e9 fixed the others.

Jose E. Marchesi d4777acbc9 New probe type: DTrace USDT probes.
This patch adds a new type of probe to GDB: the DTrace USDT probes.  The new
type is added by providing functions implementing all the entries of the
`probe_ops' structure defined in `probe.h'.  The implementation is
self-contained and does not depend on DTrace source code in any way.
