With newer versions of gcc (5.x), the extern inline we're using with the
sim-arange module no longer works. Since this code really wants the gnu
inline semantics, use that attribute explicitly.

The profile code was using STATE_WATCHPOINTS to get access to the PC, but
we already have a standard method for getting the pc, so switch to that.
This assumes that sizeof_pc is the same size as sim_cia, but we already
assume this in places by way of sim_pc_{get,set}, and this is how it's
documented in the sim-base.h API.
The current default handling for the --enable-sim-hardware option ends up
forcing the value to whatever is set as the first argument when calling
the macro (by virtue of how autoconf works). Relocate the setup code to
the 4th parameter of the AC_ARG_ENABLE macro to fix it.
This was caused by the simplification work in 1517bd2742.

If dv-sockser is available, lets add it to the common SIM_HW_OBJS
variable so it is always included automatically. Now ports do not
have to shoe horn it in directly themselves. It does mean it will
be compiled for targets that don't explicitly use it, but that's
really what we want anyways.
This lets ports assume that the dv-sockser API is always available if
they want to. This way we don't have to do an abort at configure time
and it makes the resulting code a bit simpler.
Rather than manually include tconfig.h when we think we'll need it (which
is error prone as it can define symbols we expect from config.h), have it
be included directly by config.h. Since we know we have to include that
header everywhere already, this will make sure tconfig.h isn't missed.
It should also be fine as tconfig.h is supposed to be simple and only set
up a few core defines for the target.
This allows us to stop symlinking it in place all the time and just use
it straight out of the respective source directory.
Pull out the duplicated dv_sockser_install prototype from the tconfig.in
files and put it in the one place it gets used -- sim-module.c. This is
still arguably incorrect, but it's better than the status quo where the
tconfig.in has to include header files and duplicate the dv-sockser func.
The tconfig header is meant to be simple and contain a target defines.
This dates back to the start of the repo, but has never really been used.
The sim-inline.c file has been checked in to the source, and attempts to
build it in the build tree leads to a circular dep warning from make. It
also doesn't produce a file that is usable -- it can't be compiled. Punt!
We want people to stop using the run.c frontend, but it's hard to notice
when it's still set as the default. Lets flip things so nrun.c is the
default, and users of run.c will get an error by default. We turn that
error into a warning for existing sims so we don't break them -- this is
mostly meant for people starting new ports.
Since sim-endian.c doesn't actually use sim_io funcs, it's weird to
include the sim-io.h header here. It's doing so only for the assert
header. So lets relocate the include to the right place.
... using automake 1.11.1, which is the version we're currently
using throughout, instead of 1.11.3. This should be a no-op in
practice, but will help automake/aclocal version-related
differences to cloud real changes being made.
sim/common/ChangeLog:
* aclocal.m4, configure: Regenerate using automake 1.11.1.
On Windows, a recent gnulib update imported the lstat module, and
this caused a remote-sim.c build failure in struct host_callback_struct:
In file included from /[...]/gdb/remote-sim.c:34:0:
/[...]/gdb/../include/gdb/callback.h:93:9: error: duplicate member '_stati64'
int (*lstat) (host_callback *, const char *, struct stat *);
^
What happens it that gnulib's stat.h makes the following defines:
/* Large File Support on native Windows. */
#if 1
# define stat _stati64
#endif
and then:
#if 1
# if ! 0
/* mingw does not support symlinks, therefore it does not have lstat. But
without links, stat does just fine. */
# if !(defined __cplusplus && defined GNULIB_NAMESPACE)
# define lstat stat
# endif
So, the following fields in struct host_callback_struct...
int (*stat) (host_callback *, const char *, struct stat *);
int (*fstat) (host_callback *, int, struct stat *);
int (*lstat) (host_callback *, const char *, struct stat *);
... get translated to...
int (*_stati64) (host_callback *, const char *, struct _stati64 *);
int (*_fstati64) (host_callback *, int, struct _stati64 *);
int (*_stati64) (host_callback *, const char *, struct _stati64 *);
... which causes two fields to have the same name.
This patch fixes the issue by renaming the stat-related fields
by adding a "to_" prefix, similar to what is done in GDB's
target_ops vector.
include/gdb/ChangeLog:
* callback.h (struct host_callback_struct) <to_stat>: Renamed
from "stat".
<to_fstat>: Renamed from "fstat".
<to_lstat>: Renamed from "lstat".
sim/common/ChangeLog:
* sim-io.c (sim_io_stat, sim_io_fstat): Adjust calls to "stat"
and "fstat" callbacks by calls to "to_stat" and "to_fstat" (resp)
callbacks following renaming in callback.h.
* syscall.c (cb_syscall): Likewise. Adjust calls to "lstat"
callback by call to "to_lstat" callback
sim/cris/ChangeLog:
* traps.c (cris_break_13_handler): Adjust call to "fstat" callback
by call to "to_fstat" following renaming in callback.h.
sim/h8300/ChangeLog:
* compile.c (sim_resume): Adjust calls to "stat" and "fstat"
callbacks by calls to "to_stat" and "to_fstat" (resp) callbacks
following renaming in callback.h.
GDB and SIM both have functions called "debug_printf", which conflicts
at link time. This commit shadows SIM's debug_printf with a macro so
that SIM's symbol ends up being called "sim_debug_printf".
sim/common/ChangeLog:
* sim-trace.h (debug_printf): New define.
Directories that don't use libtool need to add -ldl (on most *nix
hosts) to provide dlopen for libbfd.
config/
* plugins.m4 (AC_PLUGINS): If plugins are enabled, add -ldl to
LIBS via AC_SEARCH_LIBS.
gdb/
* acinclude.m4 (GDB_AC_CHECK_BFD): Don't add -ldl.
* config.in: Regenerate.
sim/ppc/
* configure.ac: Invoke AC_PLUGINS.
* config.in: Regenerate.
and regen lots of configure files.
It is rare for people to want to modify the cmd arg. In general, they
really shouldn't be, but a few still do. For those who misbehave, dupe
the string locally so they can bang on it.
This reverts part of the earlier version.in change. It moves
version.in back to the gdb directory. This works around the CVS bug
we've found.
gdb
* Makefile.in (version.c): Use version.in, not
common/version.in.
* common/create-version.sh: Likewise.
* common/version.in: Move...
* version.in: ...here.
gdb/doc
* Makefile.in (version.subst): Use version.in, not
common/version.in.
* gdbint.texinfo (Versions and Branches, Releasing GDB):
Likewise.
gdb/gdbserver
* Makefile.in (version.c): Use version.in, not
common/version.in.
sim/common
* Make-common.in (version.c): Use version.in, not
common/version.in.
* create-version.sh: Likewise.
sim/ppc:
* Make-common.in (version.c): Use version.in, not
common/version.in.
This change is required now that gdb/version.in has been moved to
gdb/common/version.in and now that the date needs to be fetched
from bfd/version.h.
sim/common/ChangeLog:
* create-version.sh: New script. Adapted from
gdb/commong/create-version.sh.
* Make-common.in (version.c): Update rule dependencies,
and re-implement using create-version.sh.
sim/ppc/ChangeLog:
* Makefile.in (srccom): New variable.
(version.c): Update rule dependencies, and re-implement using
sim/common/create-version.sh.
I noticed the sim code is using an old implementation of the maintainer logic.
I cut it over to the new macro (like gdb has been doing). In practice, it
makes no difference currently as nothing in the sim tree uses it, but I have a
follow up commit for the Blackfin tree that needs it.
There's no need to put the majority of the logic into the 3rd arg of the
AC_ARG_ENABLE. Coupled with the lack of indentation, it makes it hard to
follow, error prone to update, and duplicates code (with the 4th arg).
So pull the logic out of the 3rd arg and outside of the AC_ARG_ENABLE
macro. This allows us to gut the 4th arg entirely, merge with the code
that followed the macro, and fix bugs related to the new dv-sockser in
the process.
Hopefully building the various sims with the default sim-hardware
settings, as well as with explicit --{dis,en}able-sim-hardware flags,
should all just work now.
* acinclude.m4: Add SIM_DV_SOCKSER_O which is empty on hosts
which do not support dv-sockser.o. Add always as option to
first argument to SIM_AC_OPTION_HARDWARE. Fail if hardware
is always required to be enabled by simulator.
* wrapper.c: Include config.h before system header files.
* callback.c: Include config.h before system header files.
* cgen-trace.c: Likewise.
* cgen-utils.c: Likewise.
* gentmap.c: Likewise.
* sim-if.c: Include config.h before system header files.
* compile.c: Include config.h before system header files.
* sim-main.h: Likewise.
* gdb-if.c: Include config.h before system header files.
* load.c: Likewise.
* syscalls.c: Likewise.
* trace.c: Likewise.
* interp.c: Include config.h before system header files.
The common code has a sim_core_trans_addr() helper that only the m32r code
uses. Move the inline extern in the m32r code to the proper common header.

Before POSIX standardized strsignal(), old systems would hide the
prototype unless the normal extension defines were enabled. So use
the AC_USE_SYSTEM_EXTENSIONS helper for that.
Then make sure we include string.h ourselves in nrun.c rather than
relying on implicit includes via other sim headers.

The sim code gets the logic for SIM_AC_OPTION_WARNINGS from gdb, but
it hasn't been updated in a good long while. Sync with the latest
gdb code.
There is a sim specific change in here: we disable -Werror for now.
This is because all sim code atm contains warnings. Will probably
have to slowly add a white list of targets which can tolerate this
until everyone is updated.

This isn't entirely correct in that it assumes the signal numbering of
the target and host match, but seeing as we already make that assumption
in a few places, this patch doesn't make the situation any worse.

Trying to run `headers` in an out-of-tree build fails atm due to the
relative srcdir paths being used in a location other than where they
were setup to be used from. Get abs_srcdir from configure and use
that instead where applicable.
