Mike Frysinger 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.

Mike Frysinger 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.

Mike Frysinger 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.

Mike Frysinger 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
list.  Specify the input name directly to avoid fragility.

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

Mike Frysinger 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.

Mike Frysinger 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.

Mike Frysinger 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.

Joel Brobecker 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.

Some insns need to know which slot they're in to determine whether they

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

Mike Frysinger 84de2f06d8 sim: bfin: drop old linux/mii.h workarounds
We had some workarounds for old linux/mii.h headers, but it breaks with
newer ones.  So tweak the checks a bit to work with newer ones.  We'll
worry about older systems once someone complains.
