c906b4b52b sim: frv: delete UART device support
This looks like copy & paste logic from the m32r port (and history
suggests this as well).  Since building with hw & device support
enabled leads to failures:
sim/frv/devices.c: In function 'device_io_read_buffer':
sim/frv/devices.c:39:15: error: 'UART_INCHAR_ADDR' undeclared (first use in this function)

Delete it entirely.  We leave device support in place as it is used
to flush the scache.

99067e2973 Fix thinko with previous delta to RL78 sim, by adding code to define the G10 and G13 mode options.
* cpu.c (rl78_g10_mode): Declare.
	(g13_multiply): Declare.
	* cpu.h (rl78_g10_mode): Export.
	(g13_multiply): Export.

49cd1634b2 sim: dv-sockser: move build to common dir
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.

3649cb0656 sim: dv-sockser: add stub funcs when not available
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.

ae7d0cac8c sim: rename tconfig.in to tconfig.h
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.

8406bb5944 sim: dv-sockser: push module init prototype down
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.

1303206d7f sim: delete unused sim-inline.c rule
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!

465fb143c8 sim: make nrun the default run program
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.

9312936603 sim: move sim-io.h to sim-assert.h
Since sim-endian.c doesn't actually use sim_io funcs, it's weird to

header.  So lets relocate the include to the right place.

43fa85d9a8 sim: bfin: fix up linux-fixed-code.h generation [PR sim/10143]
The use of $< ends up picking the wrong object out of the depend

On BSD systems, we need to make sure all options come before the
non-options (i.e. the files).

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".
	<to_lstat>: Renamed from "lstat".

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.

6aefca7e49 Shadow SIM's debug_printf function
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.

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.

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.

0d8a6ab7d3 sim: ppc: drop $(LIBS) from psim dependency
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.

03dccef1ab sim: bfin: handle invalid HLs encoding in dsp shift insns
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.

7f5884f775 sim: bfin: se_all32bitopcodes: skip debug insns under the sim
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

and when it does, we commit the generated output, so there's almost never a
need to run directly on an end system.

31e6ad7d64 sim: use AM_MAINTAINER_MODE
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.

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).

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.

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.

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.

b909d38dfa sim: erc32: fix linking against local readline on modern (ncurses) systems
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 \
    ../../libiberty/libiberty.a -lz -lnsl \
    ../../readline/libreadline.a -lm
  ../../readline/libreadline.a(display.o): In function 'cr':
  .../readline/display.c:2486: undefined reference to 'tputs'
  collect2: ld returned 1 exit status
  make[2]: *** [sis] Error 1

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

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

73aae8efb2 sim: bfin: fix accumulator edge case saturation
When the accumulator saturates, it needs to be greater than, but not
equal to, the largest unsigned value as this is what the hardware does.

94e4274dc0 sim/ppc: Fix check for --sysroot= option
Fixes an error reported by Tristan and which can be evidenced by
doing:

        % powerpc-elf-gdb
        (gdb) target sim --sysroot=var
        Invalid option: --sysroot=/var
        [...]

sim/ppc/ChangeLog:

        * psim.c (psim_options): Fix length of comparison when checking
        for --sysroot= option.

11eef9ed35 ppc sim: Improve invalid option error message
This patch improves the error message when an invalid option is
detected, by also printing the option that actually caused the error.
For instance, from GDB:

        (gdb) target sim --hello
        Invalid option: --hello
        Usage:
        [...]

We also added the usage after an invalid long-name option (Eg: --hello)
to be in line with what's being done for all other invalid options
being detected.

sim/ppc/ChangeLog:

        * psim.c (psim_options): Add option that cause the error
        in invalid-option error messages. Print the usage when
        detecting an invalid long-name option.

8294052ca9 ppc sim: Allow --sysroot command-line option
There was a recent change that cuased the "target sim" command
to add a --sysroot option to the argument vector passed down to
the simulator.  This caused a failure in the powerpc simulator,
as it did not recognize it.  This patch fixes the problem by adding
support for the --sysroot option (it ignores it).

sim/ppc/ChangeLog:

        * psim.c (psim_options): Accept and ignore `--sysroot=...'.

1d7b4a7037 sim: bfin: import testsuite
Now that the common sim testsuite code supports .S and .c files, we
can import the Blackfin testsuite.  There are about ~800 tests here,
so I'm only attaching a compressed patch of them.  Other than adding
files to sim/testsuite/sim/bfin/, the sim/configure.tgt file was
updated to mark Blackfin as having a testsuite, and sim/configure
regenerated.

eb3243445a sim: bfin: add support for glued SIC interrupt lines
The BF537 family glues a bunch of peripherals into single interrupt lines
that run into the SIC.  To model this same behavior in the sim, we need to
use the glue-or device, and in order to use that, we need to tweak things
a bit in the mach code to allow declaring of these new devices.

082e1c4a87 sim: bfin: push SIC mappings to device tree
The machs.c file is the best place for holding cpu-specific details, so
restructure the way the SIC manages its ports to do just that.  Now the
SIC's have a standard set of input pins and the different line routing
from peripherals is kept in the device tree only.  This better models
the hardware where the SIC doesn't care about the exact peripheral that
is sending it stuff, just which input pin it gets it on.

This patch fixes a build failure at link time due to
sim_complete_command being undefined.  There was a recent change
that added this function to all the ports that do not use the
common/ subdir.  But somehow, the erc32 port got missed.

440db57552 sim: fix minor --sysroot mem leak
The current --sysroot parsing attempts to keep from leaking memory by
treating the empty string specially (sine this is the initial value),
but it ends up leaking memory when the arg is an empty string.  So if
someone uses --sysroot "", the old value is leaked, as is the new one.
