This should fix a build failure reported on x86_64-mingw32 by Daniel
Calcoen due to conflicting declarations of "open". This patch just
renames the static global in sim/rx/gdb-if.c into "rx_sim_is_open".
sim/rx/ChangeLog:
* gdb-if.c (open): Rename to...
(rx_sim_is_open): This. Replace all uses of "open" by uses of
"rx_sim_is_open" throughout.
Tested by rebuilding on x86_64-linux.
... 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.

It seems that the implementation of the SH fabs and fneg insns in the
simulator is not correct. They use the FP_UNARY macro which checks the
FPSCR.PR setting and raises an exception if PR = 1 (double precision)
and the register number is not even (i.e. a valid DF reg number).
For normal unary FP insns this is fine. However, fneg and fabs perform
the same (integer) operations regardless of the FPSCR.PR setting.
This issue initially popped up here
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63260
I've checked some of the failing tests mentioned in GCC PR 63260 above
with the patch applied and the failures go away.

* gencode.c (fabs, fneg): Implement as integer operation
instead of using the FP_UNARY macro.
GDB and SIM both have functions called "debug_printf", which conflicts

The situation here is similar to that of the other nearby (previous)
sims fixed; it fails at the dv_sockser_install declaration in
sim/m32r/tconfig.in. But, as opposed to e.g. frv, this *does* have a
definition of UART_INCHAR_ADDR et al. It's somewhat tempting to keep
sim-hardware enabled here but, I'm disabling it for the same reasons
as for frv. Unsurprisingly (as m32r seems to be the template), the
same confusing lines are in sim/m32r/Makefile.in as in
sim/frv/Makefile.in at that time, deleted in 73e76d20. Again, commit
73e76d20 (for m32r as well as for frv) attempted to move the
non-existing dv-sockser.o use to $(m32r_extra_objs) but missed that
AC_SUBST would only affect @m32r_extra_objs@ and not
$(m32r_extra_objs) per se so nothing happened. As for frv, I'm
removing the $(m32r_extra_objs) too, to avoid confusion. Make
check-sim for m32r-elf shows no regressions (5 failures; 100 expected
passes) compared to bf3d9781ec (before the recent config.in regen,
after sim-hardware mostly-enabled) and eed23bb4a1 (before the
sim-hardware mostly-enabled; 2013-03-23).

* configure.ac: Default simulator hardware to off again. Remove
dead m32r_extra_objs substitution.
* configure: Regenerate.
* Makefile.in: Remove unused frv_extra_objs.
See nearby (previous) commit for the iq2000 sim; this similarly fails
at the dv_sockser_install declaration in sim/sh64/tconfig.in. I'm
disabling simulator hardware to be consistent with the state before
94c63d78f (2013-03-23) and with the actions for the frv sim and the
iq2000 sim. Make check-sim for sh64-elf shows no regressions (25
failures; 357 expected passes) compared to bf3d9781ec (before the
recent config.in regen, after sim-hardware mostly-enabled) and
eed23bb4a1 (before the sim-hardware mostly-enabled; 2013-03-23).

See nearby (previous) commit for the frv sim; this similarly fails at
the dv_sockser_install declaration in sim/iq2000/tconfig.in. There's
no HAVE_DV_SOCKSER conditionals here and no other dv-sockser.o
artefacts so maybe there is no further fallout, but I'm going to
disable sim-hardware just be consistent with the state before
94c63d78f (2013-03-23) and with the actions for the frv sim. Make
check-sim for iq2000-elf shows no failures but that's in no small part
because it has no test-suite.

* configure.ac: Default simulator hardware to off again
without emitting errors when off or dv-sockser.o unavailable.

At 2974be626, frv-elf fails at the dv_sockser_install declaration in
sim/frv/tconfig.in. But, with the trivial #include's added (see other
sims tconfig.in, like cris or mn10300), it *still* fails building
sim/frv/devices.c because of a missing UART_INCHAR_ADDR. I have no
insight into what'd be a valid value, except that there's a definition
in m32r, which was probably used as a template with frv not finished.
Simulated hardware should not have been be enabled, and was indeed not
enabled by default before 94c63d78f (2013-03-23), where it seems to
have been enabled for no simulator-specific reason. Except
dv-sockser.o wasn't enabled even then: sim/frv/config.in wasn't
regenerated, so HAVE_DV_SOCKSER was never defined. Maybe people were
fooled by this in sim/frv/Makefile.in at that time (these two lines
were later deleted, in 73e76d20):
CONFIG_DEVICES = dv-sockser.o
CONFIG_DEVICES =
(As it seems people have missed it before: the second line overrides
the first...) I'm guessing these lines were part of the
never-completed hardware-support. Commit 73e76d20 attempted to move
the imagined dv-sockser.o from $(CONFIG_DEVICES) to $(frv_extra_objs)
but missed that AC_SUBST would only affect @frv_extra_objs@ (not
$(frv_extra_objs) per se) so nothing happened regarding sockser:
dv-sockser.o was not compiled and HAVE_DV_SOCKSER was not defined.
I'm removing the $(frv_extra_objs) too, to avoid confusion. The best
action seems to be disabling all hardware support by default again
until a specific sim maintainer finishes the work.
Make check-sim for frv-elf shows no failures after this.

sim/rx/gdb-if.c had a function named `rx_signal_to_host'. This
function mapped signal numbers used by the BSP to host signal
numbers which, at one time a while back, were used by GDB
as target signal numbers. This change updates the signal
numbers returned to be those names prefixed with "GDB_SIGNAL_"
as defined in include/gdb/signals.h.
It also changes the name of the function somewhat to better
match what the function currently does. I noticed that this
function is not static - and there's no reason for it not
to be - so I made it static too.
* gdb-if.c (rx_signal_to_host): Rename to

Many of the simulators change the SIGINT handler.
E.g., moxie/interp.c:
sigsave = signal (SIGINT, interrupt);
However, this is unnecessary.
remote-sim.h already provides an API for asynchronously stopping
a sim; and both gdb and the drivers (run.c and nrun.c at least,
I didn't check the others) install a SIGINT handler which
calls this method.

The SEARCH insn is an oddball when it comes to parallel usage. It places a
big limit on what other insns it can run in parallel with, but we don't
currently track the amount of state needed to verify this (since no other insn
really requires this). Add a note for now in case we get around to it.
For many of the 32bit dsp shift related insns, we were just ignoring the HLs
field. The hardware does not though and will reject the insn if it's set
incorrectly. Update the sim to match.
Since the sim has a few fake debug insns that the hardware does not, we
need to check for those before attempting to run them. Otherwise we'll
randomly trigger the sim debug asserts/aborts/halts insns. On the
hardware, these are proper invalid insns, and the table catches that.
The main body of the "all insn" test is executed once per tested insn, and
we test millions of insns here. Any shrinkage we can do in this loop will
speed things up nicely (since it's multiplied per tested insn).
To that end, simplify the end-of-table test into one less insn, and omit
the SSYNC when we build for the sim. When we build to run on the hardware,
this insn matters, but the sim doesn't have write store buffers in the chip
that might get in the way (memory writes are atomic).
We wrote a test case that tries every single 32bit opcode on the hardware
and compared it to the sim. There were a bunch of places in the sim where
we weren't strict enough (requiring certain parts of the opcode be set) so
we were treating a lot of invalid opcodes as valid ones. This sprinkles
out a lot additional checks in the dsp32alu class.

Since these insns run in usermode, there should be no need to setup
RET[ENI] to safe values. They won't be dereferenced, and any insn
that returns via them are valid only in supervisor mode. Since this
is in the main exception code path, saving any insn at all is good
as it gets multiplied quickly (as in O(n^2) times).

Since many people don't have a Blackfin toolchain available, only try to
regenerate the header file when in maintainer mode. This file rarely changes,
and when it does, we commit the generated output, so there's almost never a
need to run directly on an end system.
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.

This patch adds simulator support for handling the armv7 instructions
'movw (immediate)' and 'movt'.
Compiler frequently use these instructions to load the 32bit addresses of
global variables, string pointers etc. into the general registers.
In absence of support of these instructions:
1. GDB run simulator fails to print even simple "hello world" string
on console.
2. Loading of global variable addresses into the registers fail causing
arithmetic operation failures.
Patch has been regression tested for arm-none-eabi (-march=armv7-a).
These sims have optional support for the dv-sockser model, so do not make
them hard failures. The Makefile made it seem like they didn't actually
support things dynamically, but a further code dive into the source and
the Makefile shows that things work out.
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.

Some insns need to know which slot they're in to determine whether they
are valid. So add an enum for each slot, and check that rather than the
overall insn len. This makes tracking things in the code much clearer.
However, this code is functionally the same, so a follow up patch will
leverage this more to properly flag invalid parallel insn combos.

Similar to logic in the cris exp, attempt a simple compile and if it fails
(presumably due to the compiler being broken), skip all the related tests.
Fortunately, most tests (~600 out of ~800) are pure assembly, so people should
still get pretty good coverage.

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.

Overflow with shift operations happens independently of saturation, but
we have the logic merged. Extend the lshift function so that callers
can tell it when to handle each independently, and then do so when it's
needed.

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.

The 32bit allopcodes test had quite a bit of optimization added to it
so that it ran in a reasonable amount of time out of uncached memory.
Port those changes over to the 16bit test so the two share common code.

AIX 7.1 defines st_pad[123] to st_[amc]tim.tv_pad, respectively,
breaking declaration of st_pad[123] members in struct solaris_stat.
Undefine them as this is no less terrible than other solutions (like
renaming the fields and losing the binding to Solaris' names).

The current erc32 configure script only searches for -ltermcap to provide
any termcap funcs (which readlines needs). When building against a local
readline (which is static), we hit link failures like so:
gcc ...-I/-D flags... -o sis \
sis.o exec.o erc32.o func.o help.o float.o \
../../bfd/libbfd.a ../../opcodes/libopcodes.a \

Use AC_SEARCH_LIBS from gdb's configure.ac as suggested by Joel Brobecker
to check for additional termcap providers.

The cr16 libgloss port does not define these syscall numbers, so trying
to use them results in build failures [1]. The cr16 code already uses
ifdefs around a bunch of syscalls, so extend that style to cover the
ones that are currently missing. Now we can at least compile.

Building the sim on a sparc-solaris 2.8 machine fails when configured
with no extra sim hardware:
> for hw in ; do \
> echo "extern const struct hw_descriptor
> dv_${hw}_descriptor[];" ; \
> done >> tmp-hw.h
> echo 'const char version[] = "'"`sed q

> make[3]: *** [hw-config.h] Error 2
The same thing happens with the version of bash that we got from
Sun as well (which is very old: 2.03.0(1)-release).
The problems comes from the fact that both shells are buggy, and
reject the following script:
for hw in ; do
[...]
done
The above is what sim/common/Makefile.in tries to execute when
generating hw-config.h.
In order to allow users to build out of the box on these machines,
this patch works around this bug. It does rely on the fact that
none of the tokens in SIM_HW contain whitespaces.
sim/common/ChangeLog:
* Make-common.in (hw-config.h): Work around bug in Solaris 2.8
system bourne shell.
Parsing target addresses is hard if not generally useless, so use the new
cb_get_string function to lookup the associated strings as well. Now the
trace output is quickly useful instead of just marginally so.

Automake likes to dump macros automatically used into the aclocal.m4

to the more normal "acinclude.m4" so the aclocal tool can work.
