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.
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.
(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).
(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!
