Newer BF54x parts feature an updated GPIO block, so create a new
model for it.

Mike Frysinger ef0b041e05 sim: bfin: fix ASTAT/correctness issues with arithmetic shifts
This improves some of the arithmetic shifts to better match the
hardware (especially wrt ASTAT behavior).  We hit areas where
the published documentation is thin so we have to rely on tests
run on the hardware to figure out how things should behave.

Now that we check for valid sub-insns in parallel insns, we can
enable the tests that explicitly validate those code paths.

Mike Frysinger ab04c00066 sim: bfin: more parallel insn checks
Now that we keep track of the exact parallel insn slot we're in, we can
make sure that the current insn being decoded is valid for that slot.
This brings us much closer to the hardware in flagging invalid parallel
insn combinations.

Mike Frysinger 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.

a 2nd 32bit insn after the first 32bit in a parallel insn, abort.

Mike Frysinger 44ac5dbe32 sim: bfin: skip .c/.S tests if no compiler is available
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.

Mike Frysinger 2232061b1c [PATCH] sim: make sure to include strsignal prototype
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.

Mike Frysinger ac0aacdffa sim: sync build_warnings handling with gdb
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.

From: Robin Getz <robin.getz@analog.com>

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.
