fdbf396f7e Regenerate sim/common/aclocal.m4 and sim/common/configure...
... 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.

2d7bb7580a callback.h:struct host_callback_struct compilation error on Windows hosts.
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".

57df9adf2d Correct fabs and fneg insns in simulator
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.

sim/sh/ChangeLog (tiny patch):

	* gencode.c (fabs, fneg): Implement as integer operation
	instead of using the FP_UNARY macro.

9e3042ec07 Fix m32r-elf sim, default hardware to off.
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).

sim/m32r:
	* configure.ac: Default simulator hardware to off again.  Remove
	dead m32r_extra_objs substitution.
	* configure: Regenerate.
	* Makefile.in: Remove unused frv_extra_objs.

c4892a6b37 Fix sh64-elf sim, default hardware to off.
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).

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

3df3af7c3f Fix iq2000-elf sim, default hardware to off.
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.

sim/iq2000:
	* configure.ac: Default simulator hardware to off again
	without emitting errors when off or dv-sockser.o unavailable.
	* configure: Regenerate.

105dd264de Fix frv-elf sim, default hardware to off.
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/frv:
	* configure.ac: Default simulator hardware to off again.  Remove
	dead frv_extra_objs substitution.
	* configure: Regenerate.
	* Makefile.in: Remove unused frv_extra_objs.

fa0dd93eca Revise signal mapping function in GDB interface for RX sim.
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
	`rx_signal_to_gdb_signal'.  Make static.  Update all callers
	to use new name.  Use signal names from include/gdb/signals.h.

ef3e8cf7d1 sim: delete duplicate SIGINT handling
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.

When cross-compiling GDB for PPC, there's a prerequisite "-lz" for psim
that results in a build failure. With such prerequisite, GNU Make will
try to search the library from build machine's /usr/lib which is wrong.
On 64-bit Linux build machines the compilation will fail because of this.

48a9389710 sim: bfin: note missing parallel handling of SEARCH
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.

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.

531d5282c0 sim: bfin: speed up all insn testcases slightly
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).

f7f8a049bd sim: bfin: stricter insn decoding
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.

7a56db5f46 sim: bfin: drop RET[ENI] setup
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

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.

590919de6c sim: arm: add support for MOVW and MOVT instructions
From: Jayant R. Sonar <Jayant.Sonar@kpitcummins.com>

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).

1517bd2742 sim: rewrite SIM_AC_OPTION_HARDWARE a bit to simplify things
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.

d0a5a356aa include "config.h" instead of BFD's sysdep.h in d10v/interp.c
The change of include file introduces some new warnings about functions
being used without a prototype. So a few more system includes have been
added to compensate for that.

sim/d10v/ChangeLog:

        * interp.c: #include "config.h" instead of "sysdep.h".
        Add conditional include of string.h or strings.h, as well as

5f3ef9d035 Define PACKAGE macro in all sims' config.h.
Some of the common includes in include/gdb such as callback.h
include bfd.h.  But there was a recent change in bfd-in.h to
require that config.h be included before bfd.h can be included:

    /* PR 14072: Ensure that config.h is included first.  */
    #if !defined PACKAGE && !defined PACKAGE_VERSION
    #error config.h must be included before this header
    #endif

PACKAGE_VERSION is always defined by default by the AC_INIT autoconf
macro, but PACKAGE isn't.  This patch updates the SIM_AC_COMMON macro
to define it, and then regenerates all configure scripts and config.in
files.

99265d6b00 sim: bfin: keep track of the exact position of parallel insns
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.

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

Overflow with shift operations happens independently of saturation, but

96987c2b7f Work around Solaris bourne shell limitation when building the sim
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
> /[...]/../../gdb/version.in`"'";'
> >> version.c-tmp
> /bin/sh: -c: line 1: syntax error near unexpected token `;'
> /bin/sh: -c: line 1: `for hw in  ; do \'
> 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.

        * Make-common.in (hw-config.h): Work around bug in Solaris 2.8

When the shift magnitude exceeds 32 bits, the values rotate around (since

The shift magnitude is a 5-bit signed value.  When it is between 0 and
15, then we do the requested shift, but when it is outside of that, we
have to do the opposite.

That means we flip between lshift and ashiftrt to match the hardware.

Some Blackfin parts tie a bunch of interrupt lines into a single OR
gate before feeding the result into the SIC.  The glue-or device in
the sim provides a nice way of modeling this exact behavior.  At the
moment though, it requires the device to be mapped into the address
space so that things could write to it directly.  This is not needed
for the Blackfin usage, so make it optional.  Now the glue devices

fcd1ee07d3 sim: bfin: add missing VS set with add/sub insns
The 16bit add/sub insns missed setting the VS bit in ASTAT whenever the
V bit was also set.

b72cc8e145 sim: bfin: fix GPIO logic bugs when processing events
We need the DIR bit cleared, not set, in order for the pin to be treated
as an input.

When looking up the data value, we need to shift the "level" value over by
"my_port" rather than "bit" as the latter has already been shifted over.
We also should normalize the "level" coming in from the outside worlds to
the set of {0,1} since those are the only values that matter to GPIOs.

We need the BOTH bit set, not cleared, in order for the pin to trigger
on both edges.

eaf863cd1e sim: bfin: fix clear/set/toggle GPIO handling
The clear/set/toggle MMRs aren't backed by "real" data; they implicitly
perform bit operations on the associated data register.  So when we go
to process writes to them, we need to adjust the pointer accordingly so
that the actual backing data is modified.

9922f80319 sim: bfin: fix inverted W1C logic
When I originally wrote the w1c helper funcs, I used it in a few places.
Then I forgot how it worked and when I later documented it, I described
the 3rd arg in the exact opposite way it is actually used.  This error
propagated to a bunch of devices registers that were not explicitly
tested (a bunch of the devices are stubs which merely exist to say "no
device is connected" to make device drivers happy).

So once the documentation is unscrewed, fix all of the broken call sites.

8e670c0a3f sim: bfin: update VIT_MAX behavior to match hardware when Acc.X bits are set
The Blackfin PRM says that the top 8 bits of the accumulator must be
cleared when using the VIT_MAX insn, so the sim has followed this spec.
Matching the hardware behavior though when the high bits are not cleared
is easy to do and doesn't break existing behavior, so go for it.

de0addfbef sim: bfin: always do 16bit sign extension with the SEARCH insn
The Blackfin PRM does not cover this case, but the hardware is clear: even
if the search criteria is not met (and thus a new 16bit value is loaded up
into the accumulator), the accumulator undergoes 16bit sign extension.  So
simply reload the low signed 16bits in that case.

e4a861d14b sim: bfin: fix thinko in SIC pin encoding
When encoding the SIC/pin info into unique input port ids, I used bases
of 100 when I meant to use 0x100.  Rather than simply fix the decoding
math in the different functions, create a few helper macros to simplify
the SIC/pin encoding and decoding steps.  This makes the resulting tables
nice & clear.

And now that pins are clear, the 533 and 537 port_event handlers may
easily be merged into one.
