b6061d4d38 sim/common: Fix warnings: "warning: implicit declaration of function..."
During building of several cgen simulator's I notices the below
warnings.  Adding includes fixes these.

Including config.h allows stdio.h to properly configure itself to expose
asprintf().

The other warnings for abort, free, memset, strlen are trivial.

67f8b42f3e Fix the sim build
Simon pointed out that the "common/" include change in gdb broke the
sim build.  The problem was that the sim was using gdb's
create-version.sh, which changed.

This patch copies create-version.sh to the sim, so that it can
generate "version.c" in a way that works in the sim build.

Tested by rebuilding.

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.

c5ebe0ff70 sim: Don't overwrite stored errno in sim_syscall_multi
The host syscall callback mechanism should take care of updating the
errcode within the CB_SYSCALL struct, and we should not be adjusting
the error code once the syscall has completed.  We especially, should
not be rewriting the syscall errcode based on the value of errno some
time after running the host syscall, as there is no guarantee that
errno has not be overwritten.

To perform a syscall we call cb_syscall (in syscall.c).  To return
from cb_syscall control passes through one of two exit paths these are
labeled FinishSyscall and ErrorFinish and are reached using goto
statements scattered throughout the cb_syscall function.

In FinishSyscall we store the syscall result in 'sc->result', and the
error code is transated to target encoding, and stored in
'sc->errcode'.

In ErrorFinish, we again store the syscall result in 'sc->result', and
fill in 'sc->errcode' by fetching the actual errno from the host with
the 'cb->get_errno' callback.

In both cases 'sc->errcode' will have been filled in with an
appropriate value.

Further, if we look at a specific syscall example, CB_SYS_open, in
this case the first thing we do is fetch the path to open from the
target with 'get_path', if this fails then the errcode is returned,
and we jump to FinishSyscall.  Notice that in this case, no host
syscall may have been performed, for example a failure to read the
path to open out of simulated memory can return EINVAL without
performing any host syscall.  Given that no host syscall has been
performed, reading the host errno makes absolutely no sense.

This commit removes from sim_syscall_multi the rewriting of
sc->errcode based on the value of errno, and instead relies on the
value stored in the cb_syscall.

sim/common/ChangeLog:

	* sim-syscall.c (sim_syscall_multi): Don't update sc->errcode at
	this point, it should have already been set in cb_syscall.

23ebf37881 sim/cris: Fix references to cgen cpu directory
Don't assume that cgen is located within the binutils-gdb tree.  We
already have CGEN_CPU_DIR and CPU_DIR defined, these are the cpu/
directory within cgen, and the cpu/ directory within binutils-cpu.

The cris target tries to find CPU_DIR relative to the cgen source
tree, which can be wrong when building with an out of tree cgen.

sim/cris/ChangeLog:

	* Makefile.in: Replace uses of CGEN_CPU_DIR with CPU_DIR, and
	remove the definition of CGEN_CPU_DIR.

7fb45a6895 sim/opcodes: Allow use of out of tree cgen source directory
When configuring with '--enbale-cgen-maint' the default for both the
opcodes/ and sim/ directories is to assume that the cgen source is
within the binutils-gdb source tree as binutils-gdb/cgen/.

In the old cvs days, this worked well, as cgen was just another
sub-module of the single cvs repository and could easily be checked
out within the binutils-gdb directory, and managed by cvs in the
normal way.

Now that binutils-gdb is in git, while cgen is still in cvs, placing
the cgen respository within the binutils-gdb tree is more troublesome,
and it would be nice if the two tools could be kept separate.

Luckily there is already some initial code in the configure.ac files
for both opcodes/ and sim/ to support having cgen be located outside
of the binutils-gdb tree, however, this was speculative code written
imagining a future where cgen would be built and installed to some
location.

Right now there is no install support for cgen, and so the configure
code in opcodes/ and sim/ doesn't really do anything useful.  In this
commit I repurpose this code to allow binutils-gdb to be configured so
that it can make use of a cgen source directory that is outside of the
binutils-gdb tree.

With this commit applied it is now possible to configure and build
binutils-gdb like this:

    /path/to/binutils-gdb/src/configure --enable-cgen-maint=/path/to/cgen/src/cgen/
    make all-opcodes
    make -C opcodes run-cgen-all

Just in case anyone is still using cgen inside the binutils-gdb tree,
I have left the default behaviour of '--enable-cgen-maint' (with no
parameter) unchanged, that is it looks for the cgen directory as
'binutils-gdb/cgen/'.

c1230d1bab [src/erc32] Use ncurses instead of termcap on Cygwin too
This removes a Cygwin-specific libtermcap hack that was dependent on
the presence of one of the multiple alternative libraries.  The one it
was hard-coded to pick isn't included with Cygwin anymore.

According to Corinna, libtermcap was removed from Cygwin a long time
ago, and libncurses is used in Cygwin for a long time too.

The fix is to make Cygwin use the same autoconf code to figure out the
correct lib as any other target.

sim/erc32/Changelog:
2018-10-30  Joel Sherrill <joel@rtems.org>

2283a21049 Change "xor" name in cpu_core to allow building with iso646.h or C++ compiler
This code was introduced back in 1998, and C99 appeared next year,
defining the `xor` as an 'alternative keyword' if iso646.h is
included. Moreover, C++98 defines it on the language level. As a
result, the code is not buildable with C++ compiler or if iso646.h is
included beforehand.
According to comment, `sim_cpu_core` is mostly a clone of `sim_core`,
so I renamed it to `byte_xor` as it's called in `sim_core`.

sim/common/ChangeLog:

	* sim-core.h (sim_cpu_core): Rename cpu_core.xor to

d0ac1c4488 Bump to autoconf 2.69 and automake 1.15.1
When trying to run the update-gnulib.sh script in gdb, I get this:

Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^      =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1.
Aborting.

Apparently, it's an issue with a regex in automake that triggers a
warning starting with Perl 5.22.  It has been fixed in automake 1.15.1.
So I think it's a good excuse to bump the versions of autoconf and
automake used in the gnulib import.  And to avoid requiring multiple
builds of autoconf/automake, it was suggested that we bump the required
version of those tools for all binutils-gdb.

For autoconf, the 2.69 version is universally available, so it's an easy
choice.  For automake, different distros and distro versions have
different automake versions.  But 1.15.1 seems to be the most readily
available as a package.  In any case, it's easy to build it from source.

I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ,
because I don't think they are useful in our case.  They only specify a
lower bound for the acceptable version of automake/autoconf.  That's
useful if you let the user choose the version of the tool they want to
use, but want to set a minimum version (because you use a feature that
was introduced in that version).  In our case, we force people to use a
specific version anyway.  For the autoconf version, we have the check in
config/override.m4 that enforces the version we want.  It will be one
less thing to update next time we change autotools version.

I hit a few categories of problems that required some changes.  They are
described below along with the chosen solutions.

Problem 1:

  configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated.  For more info, see:
  configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation

Solution 1:

  Adjust the code based on the example at that URL.

Problem 2 (in zlib/):

  Makefile.am: error: required file './INSTALL' not found
  Makefile.am:   'automake --add-missing' can install 'INSTALL'
  Makefile.am: error: required file './NEWS' not found
  Makefile.am: error: required file './AUTHORS' not found
  Makefile.am: error: required file './COPYING' not found
  Makefile.am:   'automake --add-missing' can install 'COPYING'

Solution 2:

  Add the foreign option to AUTOMAKE_OPTIONS.

Problem 3:

  doc/Makefile.am:20: error: support for Cygnus-style trees has been removed

Solution 3:

  Remove the cygnus options.

Problem 4:

  Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')

Solution 4:

  Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is
  already defined earlier).

Problem 5:

  doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead
  doc/Makefile.am: warning: Oops!
  doc/Makefile.am:     It appears this file (or files included by it) are triggering
  doc/Makefile.am:     an undocumented, soon-to-be-removed automake hack.
  doc/Makefile.am:     Future automake versions will no longer place in the builddir
  doc/Makefile.am:     (rather than in the srcdir) the generated '.info' files that
  doc/Makefile.am:     appear to be cleaned, by e.g. being listed in CLEANFILES or
  doc/Makefile.am:     DISTCLEANFILES.
  doc/Makefile.am:     If you want your '.info' files to be placed in the builddir
  doc/Makefile.am:     rather than in the srcdir, you have to use the shiny new
  doc/Makefile.am:     'info-in-builddir' automake option.

Solution 5:

  Rename .texinfo files to .texi.

Problem 6:

  doc/Makefile.am: warning: Oops!
  doc/Makefile.am:     It appears this file (or files included by it) are triggering
  doc/Makefile.am:     an undocumented, soon-to-be-removed automake hack.
  doc/Makefile.am:     Future automake versions will no longer place in the builddir
  doc/Makefile.am:     (rather than in the srcdir) the generated '.info' files that
  doc/Makefile.am:     appear to be cleaned, by e.g. being listed in CLEANFILES or
  doc/Makefile.am:     DISTCLEANFILES.
  doc/Makefile.am:     If you want your '.info' files to be placed in the builddir
  doc/Makefile.am:     rather than in the srcdir, you have to use the shiny new
  doc/Makefile.am:     'info-in-builddir' automake option.

Solution 6:

  Remove the hack at the bottom of doc/Makefile.am and use
  the info-in-builddir automake option.

Problem 7:

  doc/Makefile.am:35: error: required file '../texinfo.tex' not found
  doc/Makefile.am:35:   'automake --add-missing' can install 'texinfo.tex'

Solution 7:

  Use the no-texinfo.tex automake option.  We also have one in
  texinfo/texinfo.tex, not sure if we should point to that, or move it
  (or a newer version of it added with automake --add-missing) to
  top-level.

Problem 8:

  Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory,
  Makefile.am:131: but option 'subdir-objects' is disabled
  automake: warning: possible forward-incompatibility.
  automake: At least a source file is in a subdirectory, but the 'subdir-objects'
  automake: automake option hasn't been enabled.  For now, the corresponding output
  automake: object file(s) will be placed in the top-level directory.  However,
  automake: this behaviour will change in future Automake versions: they will
  automake: unconditionally cause object files to be placed in the same subdirectory
  automake: of the corresponding sources.
  automake: You are advised to start using 'subdir-objects' option throughout your
  automake: project, to avoid future incompatibilities.

Solution 8:

  Use subdir-objects, that means adjusting references to some .o that will now
  be in config/.

Problem 9:

fa8b7c2128 sim: or1k: add or1k target to sim
This adds the OpenRISC 32-bit sim target.  The OpenRISC sim is a CGEN
based sim so the bulk of the code is generated from the .cpu files by
CGEN.  The engine decode and execute logic in mloop uses scache with
pseudo-basic-block extraction and supports both full and fast (switch)
modes.

The sim does not implement an mmu at the moment.  The sim does implement
fpu instructions via the common sim-fpu implementation.

3b4b0a629a FT32: support for FT32B processor - part 1
FT32B is a new FT32 family member. It has a code
compression scheme, which requires the use of linker
relaxations. The change is quite large, so submission
is in several parts.

Part 1 adds a 15-bit instruction field, and CPU-specific functions for
the code compression that are used in binutils and GDB.

625ce09c1c Define an error function in the PPC simulator library.
Previously this used the error function from GDB directly when linked
against GDB instead of the error method in the host callbacks
structure.  This was exposed via a link error when GDB was converted
to C++.  The error function invokes the error callback similar to
sim_io_error.

Note that there are also error functions in sim/ppc/main.c and
sim/ppc/misc.c.  The ppc libsim.a expects each consumer to provide
several symbols used by the library including "error".  sim-calls.c
provides these symbols when the library is linked into gdb.  The dgen,
igen, tmp-filter, tmp-ld-decode, tmp-ld-cache, and tmp-ld-insn programs
use the functions from misc.c.  psim uses the functions from main.c.

003ca0fd22 Refactor disassembler selection
Nowadays, opcodes/disassemble.c:disassembler selects the proper
disassembler according to ABFD only.  However, it actually
selects disassemblers according to arch, mach, endianess, and
abfd.  This patch adds them to the parameters of disassembler,
so that its caller can still select disassemblers in case that
abfd is NULL (a typical case in GDB).

There isn't any functionality change.
