No other sub directory provides such a configuration option, so
drop it from the sim dir as well. This cleans up a good bit of
code in the process.
If people want to use custom flags for just the sim, they can
still run configure+make by hand in the sim subdir and use the
normal CFLAGS settings.
The cris sim hit a few failures after the recent getopt logic, and the
expected output showed a few ways we can improve things to better match
other utils.
Rather than re-invent endian defines, as well as maintain our own list
of OS & arch-specific includes, punt all that logic in favor of the bfd
ones already set up and maintained elsewhere. We already rely on the
bfd library, so leveraging the endian aspect should be fine.
The cris port was using the device framework to handle two addresses when
the --cris-900000xx flag was specified. That can be implemented using the
newer hardware framework instead which allows us to drop the device logic
entirely, as well as delete the tconfig.h file. Basically we create a new
cris_900000xx device model and move the read logic out of devices.c and
into that. The rest of the devices logic was callback to the hardware
framework already.
Much like we autodetect the path to the run program when there is none
set explicitly, do the same for the rvdummy program. Otherwise the
default make check fails to execute the helper properly.
Most targets already default to loading code via their LMA, but for
a few, this means the default changes from loading VMA to LMA. It's
better to have the different targets be consistent, and allows some
code clean up.
Sometimes in tests, we need supplemental files like linker scripts or
board helper files. There's no way to set those flags in the tests
currently and relative paths don't work (breaks out of tree builds).
Update the main option parser to replace some strings on the fly. Now
tests can do things like:
Long term we'll want to switch the framework to use the dejagnu helpers
like dg-xxx that gcc & gdb utilize. But that'll require more rework.
When handling left saturated ashifts with negative immediates, they
should be treated as right ashifts. This matches hardware behavior.

The nrun conversion was slightly incorrect in how it stopped when an
exception occurred. We still set cpu.asregs.exception, but nothing
was checking it anymore. Convert all of that to sim_engine_halt.
To keep things from regressing again, add a basic testsuite too.
A lot of cpu state is stored in global variables, as is memory handling.
The sim_size support needs unwinding at some point. But at least this
is an improvement on the status quo.
Looks like historical restructuring in this dir lost the d10v-elf subdir
and no one noticed in the meantime. Re-add it to the testsuite.
There are some failures, but better some tests get run than none at all.
Since the sim doesn't have any debug support in it, we can only exit
cleanly. But this is still better than nothing.
Change the default microblaze sim to not dump the debug load output
when running. No other does this, and it breaks the testsuite.
If a test doesn't write anything at all to stdout, the current test
framework can't support that. Even if you put a blank output line:
# output:
the setup happily clobbers that with a default pass/fail string.
Tweak the parsing logic so we only set the output to pass/fail when
the test has no output marker.
Since the testsuite subdir has to handle dynamic arch values already,
there's no real value in requiring arches to opt in to it. Most have
a testsuite now anyways, and we're requiring it in the future.
I meant for this script to be +x, but missed when doing the initial CVS
commit. It wasn't possible to fix w/CVS, but it is w/git, so do it.

* run-tests.sh: Add +x file mode.
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).
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).

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).
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
