There are no sockets on djgpp.  This #ifdef's out the bits in the file
that use sockets, depending on whether winsock or sys/socket.h is
available.

As alternative approach, given ser-tcp.c, ser-pipe.c, etc. are split
into separate files, and which to use is selected by configure.ac:

 dnl Figure out which of the many generic ser-*.c files the _host_ supports.
 SER_HARDWIRE="ser-base.o ser-unix.o ser-pipe.o ser-tcp.o"

 AC_SUBST(SER_HARDWIRE)

... I considered splitting filestuff.c similarly.  But I quickly gave
up on the idea, as it looked like a lot more complication over this
approach, for no real gain.  Plus, there are uses of these functions
outside the ser*.c framework.

range stepping: gdbserver (x86 GNU/Linux)

This patch adds support for range stepping to GDBserver, teaching it
about vCont;r.

It'd be easy to enable this for all hardware single-step targets
without needing the linux_target_ops hook, however, at least PPC needs
special care, due to the fact that PPC atomic sequences can't be
hardware single-stepped through, a thing which GDBserver doesn't know
about.  So this leaves the support limited to x86/x86_64.

range stepping: gdb

This patch teaches GDB to take advantage of target-assisted range
stepping.  It adds a new 'r ADDR1,ADDR2' action to vCont (vCont;r),
meaning, "step once, and keep stepping as long as the thread is in the
[ADDR1,ADDR2) range".

Rationale:

When user issues the "step" command on the following line of source,

   a = b + c + d * e - a;

GDB single-steps every single instruction until the program reaches a
new different line.  E.g., on x86_64, that line compiles to:

   0x08048434 <+65>:    mov    0x1c(%esp),%eax
   0x08048438 <+69>:    mov    0x30(%esp),%edx
   0x0804843c <+73>:    add    %eax,%edx
   0x0804843e <+75>:    mov    0x18(%esp),%eax
   0x08048442 <+79>:    imul   0x2c(%esp),%eax
   0x08048447 <+84>:    add    %edx,%eax
   0x08048449 <+86>:    sub    0x34(%esp),%eax
   0x0804844d <+90>:    mov    %eax,0x34(%esp)
   0x08048451 <+94>:    mov    0x1c(%esp),%eax

and the following is the RSP traffic between GDB and GDBserver:

 --> vCont;s:p2e13.2e13;c
 <-- T0505:68efffbf;04:30efffbf;08:3c840408;thread:p2e13.2e13;core:1;
 --> vCont;s:p2e13.2e13;c
 <-- T0505:68efffbf;04:30efffbf;08:3e840408;thread:p2e13.2e13;core:2;
 --> vCont;s:p2e13.2e13;c
 <-- T0505:68efffbf;04:30efffbf;08:42840408;thread:p2e13.2e13;core:2;
 --> vCont;s:p2e13.2e13;c
 <-- T0505:68efffbf;04:30efffbf;08:47840408;thread:p2e13.2e13;core:0;
 --> vCont;s:p2e13.2e13;c
 <-- T0505:68efffbf;04:30efffbf;08:49840408;thread:p2e13.2e13;core:0;
 --> vCont;s:p2e13.2e13;c
 <-- T0505:68efffbf;04:30efffbf;08:4d840408;thread:p2e13.2e13;core:0;
 --> vCont;s:p2e13.2e13;c
 <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2e13.2e13;core:0;

IOW, a lot of roundtrips between GDB and GDBserver.

If we add a new command to the RSP, meaning "keep stepping and don't
report a stop until the program goes out of the [0x08048434,
0x08048451) address range", then the RSP traffic can be reduced down
to:

 --> vCont;r8048434,8048451:p2db0.2db0;c
 <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2db0.2db0;core:1;

As number of packets is reduced dramatically, the performance of
stepping source lines is much improved.

In case something is wrong with range stepping on the stub side, the
debug info or even gdb, this adds a "set/show range-stepping" command
to be able to turn range stepping off.

Centralize workaround for Python 2.6's Py_DECREF.

Wrap/redefine Py_DECREF ourselves, avoiding the need for uses to care
about extra braces due to the fact that Python only started wrapping Py_DECREF
in 'do {} while (0)' after 2.6.

bfd/elf64-aarch64.c: Remove dead code.

The relocs_copied member is never assigned a non-NULL value, so
this code does not appear to be used.

bfd/ChangeLog:

Add missing empty line after var declarations in handle_unload_dll

gdb/ChangeLog:

        * windows-nat.c (handle_unload_dll): Add missing empty line.

* config/tc-ppc.c (md_apply_fix): Hoist code common to insn
and data fixups performing shift/high adjust/sign extension on
fieldval.  Sink fx_pcrel handling and checks.  Use fixP->fx_size

[dwarf] Mark all functions as prototyped except C functions.

This makes sure that the types of the arguments are taken into account
when performing an inferior function call to a non-C (or C-like)
function.  In particular, this makes sure that the arguments are
appropriatly converted to the correct type.

For instance, on x86_64-linux, with the following Ada code:

   procedure Set_Float (F : Float) is
   begin
      Global_Float := F;
   end Set_Float;

The following sequence shows that Float arguments are incorrectly
passed (Ada's Float type is the equivalent of type "float" in C):

    (gdb) call set_float (2.0)
    (gdb) print global_float
    $1 = 0.0

Putting a breakpoint inside set_float to inspect the value of
register xmm0 gives the first hint of the problem:

    (gdb) p $xmm0
    $2 = (v4_float => (0 => 0.0, 2.0, 0.0, 0.0),
          v2_double => (0 => 2.0, 0.0),
    [...]

It shows that the argument was passed as a double.

The code responsible for doing appropriate type conversions
for the arguments (value_arg_coerce) found that our function
was not prototyped, and thus could not use typing information
for the arguments. Instead, it defaulted to the value of "set
coerce-float-to-double", which by default is true, to determine
the argument type.

This patch fixes the problem by setting the PROTOTYPE flag
for all functions of any language except C and Objective C.

gdb/ChangeLog:

        * dwarf2read.c (prototyped_function_p): New function.
        (read_subroutine_type): Use it.

gdb/testsuite/ChangeLog:

        * gdb.ada/float_param: New testcase.

De-indent example code in rs6000-aix-tdep.c (ARI fix)

This patch de-indents the code provided as a comment explaining
how the code declaring the ld_info32_desc and ld_info64_desc globals
was generated. The intent is to avoid an ARI warning about a macro
not starting at column zero of the line.

gdb/ChangeLog:

        * rs6000-aix-tdep.c: De-indent some example code provided
        as a comment.
