Jeff Law
9fca2fd3c6 * gencode.c: Fix various indention & style problems. 
Remove test code.  Remove #if 0 code.
        * interp.c: Provide prototypes for all static functions.
        Fix minor indention problems.
        (sim_open, sim_resume): Remove unused variables.
        (sim_read): Return type is "int".
        * simops.c: Remove unused variables.
        (divh): Make result of divide-by-zero zero.
        (setf): Initialize result to keep compiler quiet.
        (sar instructions): These just clear the overflow bit.
        * v850_sim.h: Provide prototypes for put_byte, put_half
        and put_word.

d81352b8b8 * interp.c: OP should be an array of 32bit operands! 
(v850_callback): Declare.
        (do_format_5): Fix extraction of OP[0].
        (sim_size): Remove debugging printf.
        (sim_set_callbacks): Do something useful.
        (sim_stop_reason): Gross hacks to get c-torture running.
        * simops.c: Simplify code for computing targets of bCC
        insns.   Invert 's' bit if 'ov' bit is set for some
        instructions.  Fix 'cy' bit handling for numerous
        instructions.  Make the simulator stop when a halt
        instruction is encountered.  Very crude support for
        emulated syscalls (trap 0).
        * v850_sim.h: Include "callback.h" and declare
        v850_callback.  Items in the operand array are 32bits.
Fixes & syscall stuff.

So we've got a chance of simulating something like btst #0,@40:8 correctly.

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.

2434e38489 * gencode.c (tab): Added several sh3 opcodes. 
(think): Added printonmatch for A_SSR and A_SPC.

 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.
