8517f62b16 Ref gdb/11763 - can't stop a running simulator: 
o	Provide poll_quit callback to simulators
		so that they can poll for SIGINT on
		clueless OS's.

	o	Add sim_stop to simulators so that clients
		can request a halt (eg gdbtk's STOP button)
		Works for PPC!

	o	Re-arange remote-sim.c so that the
		hard work is moved from gdbsim_resume()
		to gdbsim_wait() (where it should be).

        function.
        (do_formats_9_10): Rough cut so shift ops will work.
        (sim_resume): Tweak to deal with format 1 and format 2
        handling in a single funtion.  Don't update the PC
        for format 3 insns.  Fix typos.
        * simops.c: Slightly reorganize.  Add condition code handling
        to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
        and "not" instructions.
        * v850_sim.h (reg_t): Registers are 32bits.
        (_state): The V850 has 32 general registers.  Add a 32bit
        psw and pc register too.  Add accessor macros
Fixing lots of stuff.  Starting to add condition code support.  Basically
check pointing the work to date.

This is an intermediate checkin. The work of removing "long long"
usage is not yet finished. These changes are clean, and have been
sitting on my machine for a while (whilst doing other work), and it is
safer for them to be checked in.

J.T. Conklin
2434e38489 * gencode.c (tab): Added several sh3 opcodes. 
(think): Added printonmatch for A_SSR and A_SPC.
* interp.c (SSR, SPC): Added definitions.
(saved_state_type): Added ssr and spc registers.
 1995-12-04 20:27:38 +00:00
Jackie Smith Cashion
8bae0a0c48 * gencode.c: Tidied instruction decoding, and added FP instruction 
support.
* interp.c: Added dineroIII, and BSD profiling support. Also
run-time FP handling.

At the moment the options are still mostly build-time controlled,
rather than run-time. Also work still needs to be done to remove (long
long) usage (However this is trivial, just time-consuming).

The out-standing instruction work to be done is in supporting round
and trunc for FP operations, and providing better exception support.

8ad5773724 Initial check-in of the MIPS simulator. Work still needs to be done on 
the run-time support code (interp.c) to provide better tracing, and
also to add profiling and architecture specific support. At the moment
the simulator has a fixed size, fixed address memory area, and
simulates a subset of the IDT monitor calls (enough to execute test
programs).

The other major feature (could even be a bug) is that the simulator
makes use of the GCC "long long" extension. Work has been started to
make this a build configuration option... but there is still a lot of
this to be done.
