Pedro Franco de Carvalho [Mon, 6 Aug 2018 19:24:55 +0000 (16:24 -0300)] 
Use remote register numbers in tracepoint mask

Currently, tracepoint register masks in the QTDP packets include both
internal and remote register numbers, as well as pseudo-register
numbers.

This patch changes this so that the mask only includes remote register
numbers.

Register numbers from agent expressions are already set in the mask
using remote numbers.  Other tracepoint actions used internal numbers,
e.g. "collect $regs" or "collect $<pseudoreg>".  To handle pseudoreg
numbers, an empty agent expression is created and ax_reg_mask is
called for this expression and the pseudoreg.  This will cause the ax
to set its mask with the corresponding remote raw register
numbers (using ax_regs_mask, which calls
gdbarch_ax_pseudo_register_collect).

If ax_regs_mask and gdbarch_ax_pseudo_register_collect also generate
more ax bytecode, the ax is also appended to the collection list.  It
isn't clear that this was the original intent for
gdbarch_ax_pseudo_register_collect, and none of the arches seem to do
this, but if this changes in the future, it should work.

The patch also refactors the code used by validate_action line to
validate axs into a function that is now called from every place that
generates axs.  Previously, some parts of tracepoint.c that generated
axs didn't check if the ax length was greater than MAX_AGENT_EXPR_LEN.

Use get_remote_packet_size in download_tracepoint

This patch changes the remote target to use the remote packet size to
build QTDP packets, and to check if there is enough room for the
packet.

I changed the function to raise an error if the packet is too small,
instead of aborting gdb (through xsnprintf).  It isn't clear if gdb
will be in a consistent state with respect to the stub after this,
since it's possible that some packets will be sent but not others, and
there could be an incomplete tracepoint on the stub.

The char array used to build the packets is changed to a
gdb::char_vector and sized with the result from
get_remote_packet_size.

When checking if the buffer is large enough to hold the tracepoint
condition agent expression, the length of the expression is multiplied
by two, since it is encoded with two hex digits per expression
byte.  For simplicity, I assume that the result won't overflow, which
can happen for very long condition expressions.

Update dg-extract-results.* from gcc

When looking at the gdb.sum file produced by dg-extract-results.sh on
Solaris 11/x86, I noticed some wrong sorting, like this:

PASS: gdb.ada/addr_arith.exp: print something'address + 0
PASS: gdb.ada/addr_arith.exp: print 0 + something'address
PASS: gdb.ada/addr_arith.exp: print something'address - 0
PASS: gdb.ada/addr_arith.exp: print 0 - something'address

Looking closer, I noticed that while dg-extract-results.sh had been
copied over from contrib in the gcc repo, the corresponding
dg-extract-results.py file had not.  The latter not only fixes the
sorting problem I'd observed, but is also way faster than the shell
version (like a factor of 50 faster).

Therefore I propose to update both files from the gcc repo.  The changes
to the .sh version are trivial, just counting the number of DejaGnu
ERROR lines, too.

The files are moved to toplevel contrib:

* This way, they can easily be used should someone decide to parallelize
  one or more of the binutils, gas, or ld testsuites.

* They are less easily overlooked for updates from the gcc repo when
  they reside in the same place in both.

* The test_summary script needs to live in contrib since the toplevel

Fix thinko when deciding whether to disable TCP's Nagle algorithm

This patch fixes a thinko that happened when I was implementing the
IPv6 support on GDB/gdbserver.  On certain situations, it is necessary
to disable TCP's Nagle algorithm (NODELAY).  For obvious reasons, this
only applies when we are dealing with a TCP connection.

While implementing the IPv6 patch, I noticed that the net_open
function (on gdb/ser-tcp.c) kept a flag indicating whether the
connection type was UDP or TCP.  I eliminated that flag, and started
using the 'struct addrinfo *' related to the successful connection
directly.  However, I made a mistake:

  if (success_ainfo->ai_socktype == IPPROTO_TCP)
                     ^^^^^^^^^^^
    {
      /* Disable Nagle algorithm.  Needed in some cases.  */
      int tmp = 1;

      setsockopt (scb->fd, IPPROTO_TCP, TCP_NODELAY,
  (char *) &tmp, sizeof (tmp));
    }

The 'ai_socktype' field specifies the socket type (SOCK_STREAM or
SOCK_DGRAM), and not the protocol.  This test was always failing, and
the Nagle algorithm was never being disabled.

The obvious fix is to use the 'ai_protocol' field.  This is what this
patch does.

Huge "thank you" to Joel Brobecker who reported the regression (he was
experiencing an unusual delay while debugging a bare-metal program
running under QEMU) and helped me set up a proper reproducer for the
bug.

Invoking -var-info-path-expression on a dynamic varobj lead either in wrong

This was caused by the fact that varobj_get_path_expr() called
cplus_path_expr_of_child() ignoring the fact the parent of the variable

I extended the regular expression being used to identify whether
gdbserver could not resolve a (host)name.  This was needed because the
error message being printed had a different variation across some

has yet another variation:

decided to just match anything after the "cannot resolve name: " part.
This patch implements that.

gdb: Don't call gdb_load_shlib unless GDB is running

The gdb_load_shlib function will, on remote targets, try to run some

running.

The gdb.trace/tspeed.exp test calls gdb_load_shlib before starting
GDB.  Don't do that.

The failure that's triggered is actually DeJaGNU complaining that the
variable $use_gdb_stub doesn't exist, this is only created when GDB is

This commit also adds a check to gdb_load_shlib that GDB is running.
The check is always performed, so this should catch cases where a GDB
developer adds a use of gdb_load_shlib but doesn't test their code

Improve gcore manpage and clarify "-o" option

Ref.: https://bugs.debian.org/904628

It has been reported that gcore's manpage is a bit imprecise when it
comes to two things:

- It doesn't explicity say that the command accepts more than one PID
  on its CLI.

- It fails to mention that the argument passed through the "-o" option
  is actually a prefix that will be used to compose the corefile's
  filename, and not the actual filename.

I decided to give it a try and rewrite parts of the text to further
clarify these two points.  I ended up rewording the "Description"
section because, IMHO, it was a bit confuse to understand.

To make things consistent, I've also renamed the "$name" variable in
