Pedro Alves a2a79012fe gdb: Remove OpenBSD/m88k support
Support for m88k was fully removed from bfd, which broke gdb
--enable-targets=all builds:

  > gdb/m88k-tdep.c: In function void _initialize_m88k_tdep():
  > gdb/m88k-tdep.c:867:21: error: bfd_arch_m88k was not declared in this scope
  >    gdbarch_register (bfd_arch_m88k, m88k_gdbarch_init, NULL);

There's no point in keeping GDB support for OpenBSD/m88k with no bfd
support, so this commit simply removes the port.

Rainer Orth 281c444773 Remove support for Solaris < 10 (PR gdb/22185)
Given that GCC has obsoleted/removed support for Solaris 9 in GCC 4.9/5 in 2013:

    https://gcc.gnu.org/gcc-4.9/changes.html
    https://gcc.gnu.org/ml/gcc-patches/2013-05/msg00728.html

and the last gdb version that can be compiled with gcc 4.9 is 7.12.1 only when
configured with --disable-build-with-cxx, it's time to obsolete/remove support
for Solaris < 10.

This patch does this, simplifying configure.nat along the way (only a single
sol2 configuration with variants for i386 and sparc).

Some configure checks for older Solaris versions can go, too, and the check
for libthread_db.so.1 removed:

* Since Solaris 10, dlopen has moved to libc and libdl.so is just a
  filter on ld.so.1, so no need to check.

* $RDYNAMIC is already handled above (and is a no-op with Solaris ld
  anyway).

Both proc-service.c and sol-thread.c lose support for (Solaris-only)
PROC_SERVICE_IS_OLD.

The attached revised patch has been tested on sparcv9-sun-solaris2.10,
sparcv9-sun-solaris2.11.4, amd64-pc-solaris2.10, amd64-pc-solaris2.11.4,
and x86_64-pc-linux-gnu.

I've also started an i386-pc-solaris2.9 build to check that it really
stops as expected.

	PR gdb/22185
	* configure.host <*-*-solaris2.[01], *-*-solaris2.[2-9]*>: Mark as
	obsolete.
	Use gdb_host sol2 for i[34567]86-*-solaris2*, x86_64-*-solaris2*.
	Remove i386sol2 support.
	* configure.nat <i386sol2>: Remove.
	<sol2-64>: Fold into ...
	<sol2>: ... this.
	Move common settings to default section.
	Add sol-thread.o.

Rainer Orth 4fa7574eec Fix gdb 8.1 Solaris compilation
I just tried to compile gdb trunk on Solaris 11.4 (formerly 12), and
failed for a couple of reasons:

  Since Solaris 11, vfork () is marked deprecated in <unistd.h>.

  cf. vfork(2):

       The  vfork()  and vforkx() functions are deprecated. Their sole legiti-
       mate use as a prelude to an immediate call to a function from the  exec
       family can be achieved safely by posix_spawn(3C) or posix_spawnp(3C).

John Baldwin a379bfd00e Enable support for x86 debug registers on NetBSD.
NetBSD recently added PT_GETDBREGS and PT_SETDBREGS ptrace operations
that match the existing ones supported by x86-bsd-nat.c.  NetBSD's
headers do not provide the DBREG_DRX helper macro, so define a local
version in x86-bsd-nat.c.  In addition, add the x86-nat.o and x86-dregs.o
object files to the native NetBSD x86 build targets.

Simon Marchi 848d907446 darwin: Add fork-inferior.o to NATDEPFILES
I happened to be build-testing on macOS and found this:

  Undefined symbols for architecture x86_64:

    "fork_inferior(char const*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, char**, void (*)(), void (*)(int), void (*)(), char const*, void (*)(char const*, char* const*, char* const*))", referenced from:

        darwin_create_inferior(target_ops*, char const*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, char**, int) in darwin-nat.o

    "startup_inferior(int, int, target_waitstatus*, ptid_t*)", referenced from:

        gdb_startup_inferior(int, int) in fork-child.o

    "trace_start_error(char const*, ...)", referenced from:

        darwin_ptrace_me() in darwin-nat.o

    "trace_start_error_with_name(char const*)", referenced from:

        darwin_ptrace_me() in darwin-nat.o

  ld: symbol(s) not found for architecture x86_64

  clang: error: linker command failed with exit code 1 (use -v to see invocation)

Adding fork-inferior.o fixes it.  I factored out the Darwin bits that
are no architecture-specific in the section meant for that at the top.

I only built-tested this using Travis-CI, since I don't have access to
this platform.

gdb/ChangeLog:

	* configure.nat: Factor out Darwin bits that are not
	architecture-specific.  Add fork-inferior.o.

Simon Marchi 3b912944f4 aix: Add fork-inferior.o to NATDEPFILES

ld: 0711-317 ERROR: Undefined symbol: .startup_inferior(int, int, target_waitstatus*, ptid_t*)

Including fork-inferior.o in the build should help.  I also factored out
the AIX bits that are not architecture-specific to be consistent with the other
OSes.

Sergio Durigan Junior 2090129c36 Share fork_inferior et al with gdbserver
This is the most important (and the biggest, sorry) patch of the
series.  It moves fork_inferior from gdb/fork-child.c to
nat/fork-inferior.c and makes all the necessary adjustments to both
GDB and gdbserver to make sure everything works OK.

There is no "most important change" with this patch; all changes are
made in a progressive way, making sure that gdbserver had the
necessary features while not breaking GDB at the same time.

I decided to go ahead and implement a partial support for starting the
inferior with a shell on gdbserver, although the full feature comes in
the next patch.  The user won't have the option to disable the
startup-with-shell, and also won't be able to change which shell
gdbserver will use (other than setting the $SHELL environment
variable, that is).

Everything is working as expected, and no regressions were present
during the tests.

Sergio Durigan Junior e50f25ecdb Rearrange gdb/configure.nat to make it simpler and less redundant
The previous commit introduced gdb/configure.nat, but it was just a
copy-and-past (with the necessary adjustments) from the files under
gdb/config/.  We can do better than that.

Instead of using one big 'case' statement that matches the
${gdb_host_cpu} and then match each ${gdb_host}, it is possible to
remove a lof of redundancy by matching the most common ${gdb_host}'s
first, setting the common variables for each, and then proceed to
matching specific ${gdb_host}'s and ${gdb_host_cpu}'s.  In other
words, reverse the order of the 'case's and take advantage of the fact
that a lot of parameters are the same for each host.

This commit was tested on x86_64 without regressions.

gdb/ChangeLog:
2017-05-06  Sergio Durigan Junior  <sergiodj@redhat.com>

 	* configure.nat: Rearrange 'case' statements to match
	host before cpu.

Sergio Durigan Junior 21ea5acdd1 Introduce "gdb/configure.nat" (and delete "gdb/config/*/*.mh" files)
Due to my ongoing work to make it possible for gdbserver to start the
inferior using the shell, I had to share the fork_inferior function
under the "nat/" directory.  In order to do that, I created a new file
and put the function there; however, this meant that I now had to
update some of the *.mh files (under "gdb/config") and add the new
file as a dependency to be built natively.  Bleh...

After talking a bit to Pedro about this, the idea came up to write a
new "gdb/configure.nat" file, a la "gdb/configure.tgt", which would
concentrate all of the native settings for each host/system.  I
decided to tackle this issue.

The patch is simple.  All of the previous Makefile variables that were
being declared inside the *.mh files are now inside "gdb/Makefile.in",
and "gdb/configure" is responsible for AC_SUBST'ing them.  The
definitions of these variables were put inside "gdb/configure.nat", so
now they're shell variables.  For excerpts of Makefile code, one must
create a file under "gdb/config/${gdb_cpu_host}" and reference it on
the "nat_extra_makefile_frag" variable.

It should now be easier to update the native dependencies of hosts in
this single file.

This has been tested on x86_64 without regressions.
