8def922034 * mn10300_sim.h: Fix ordering of bits in the PSW. 1997-05-06 19:42:17 +00:00

26e9f63c11 * mn10300_sim.h (struct _state): Add space for mdrq register.
(REG_MDRQ): Define.
        * simops.c: Don't abort for trap.  Add support for the extended
        instructions, "getx", "putx", "mulq", "mulqu", "sat16", "sat24",
        and "bsch".

b774c0e4b1 * mn10300_sim.h (struct _state): Put all registers into a single
array to make gdb implementation easier.
        (REG_*): Add definitions for all registers in the state array.
        (SEXT32, SEXT40, SEXT44, SEXT60): Remove unused macros.
        * simops.c: Related changes.

d252301029 * gencode.c (write_header): Add "insn" and "extension" arguments
to the OP_* declarations.
        (write_template): Similarly for function templates.
        * interp.c (insn, extension): Remove global variables.  Instead
        pass them as arguments to the OP_* functions.
        * mn10300_sim.h: Remove decls for "insn" and "extension".
        * simops.c (OP_*): Accept "insn" and "extension" as arguments
        instead of using globals.
Starting to clean things up.

92284aaa35 * mn10300_sim.h (_state): Add another register (MDR).
(REG_MDR): Define.
        * simops.c: Implement "cmp", "calls", "rets", "jmp" and
        a few additional random insns.
We can now function calls.  We get out of crt0 into main now, then lose
when calls are nested (because don't handle movm yet).

73e6529893 * mn10300_sim.h (PSW_*): Define for CC status tracking.
(REG_D0, REG_A0, REG_SP): Define.
        * simops.c: Implement "add", "addc" and a few other random
        instructions.
Starting to simulate instructions for the mn10300.  Executes some of
the crt0 code now!

b5f831ac51 * gencode.c, interp.c: Snapshot current simulator code.
(crude) hashing works, along with dispatch to the OP_* functions.
