relative operands.

jal instruction.

variable prev. Call signal before and after simulate.
(sim_stop_reason): Add simSIGINT support.
(sim_warning, sim_error, dotrace, SignalException): Define as stdarg
functions always.
(sim_warning): Delete call to SignalException. Do call printf_filtered
if logfh is NULL.
(AddressTranslation): Add #ifdef DEBUG around debugging message and
a call to sim_warning.
* gencode.c (inst_type): Add mips16 instruction encoding types.
(GETDATASIZEINSN): Define.
(MIPS_DECODE): Add REG flag to dsllv, dsrav, and dsrlv. Add
jalx. Add LEFT flag to mfhi and mflo. Add RIGHT flag to mthi and
mtlo.

(bitmap_val): New static function.
(struct mips16_op): Define.
(mips16_op_table): New table, for mips16 operands.
(build_mips16_operands): New static function.
(process_instructions): If PC is odd, decode a mips16
instruction. Break out instruction handling into new
build_instruction function.
(build_instruction): New static function, broken out of
process_instructions. Check modifiers rather than flags for SHIFT
bit count and m[ft]{hi,lo} direction.
(usage): Pass program name to fprintf.
(main): Remove unused variable this_option_optind. Change
``*loptarg++'' to ``loptarg++''.
(my_strtoul): Parenthesize && within ||.
* interp.c (sim_trace): If tracefh is NULL, set it to stderr.
(LoadMemory): Accept a halfword pAddr if vAddr is odd.
(simulate): If PC is odd, fetch a 16 bit instruction, and
increment PC by 2 rather than 4.
* configure.in: Add case for mips16*-*-*.
* configure: Rebuild.
* interp.c (sim_monitor): Improved monitor printf
simulation. Tidied up simulator warnings, and added "--log" option
for directing warning message output.
* gencode.c: Use sim_warning() rather than WARNING macro.
INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
(docdir): Removed.
* configure.in (AC_PREREQ): autoconf 2.5 or higher.
(AC_PROG_INSTALL): Added.
(AC_PROG_CC): Moved to before configure.host call.
* configure: Rebuilt.
AC_CHECK_LIB, and AC_CHECK_FUNCS. Change AC_OUTPUT to set
stamp-h.
* configure: Rebuild.
* config.in: New file, generated by autoheader.
* interp.c: Include "config.h". Include <stdlib.h>, <string.h>,
and <strings.h> if they exist. Replace #ifdef sun with #ifdef
HAVE_ANINT and HAVE_AINT, as appropriate.
* Makefile.in (run): Use @LIBS@ rather than -lm.
(interp.o): Depend upon config.h.
(Makefile): Just rebuild Makefile.
(clean): Remove stamp-h.
(mostlyclean): Make the same as clean, not as distclean.
(config.h, stamp-h): New targets.
* interp.c (xfer_direct_word, xfer_direct_long,
swap_direct_word, swap_direct_long, xfer_big_word,
xfer_big_long, xfer_little_word, xfer_little_long,
swap_word,swap_long): Added.
* interp.c (ColdReset): Provide function indirection to
host<->simulated_target transfer routines.
* interp.c (sim_store_register, sim_fetch_register): Updated to
make use of indirected transfer routines.
* interp.c (Convert): Provide round-to-nearest and round-to-zero
support for Sun hosts.
* Makefile.in (gencode): Ensure the host compiler and libraries
used for cross-hosted build.
Allow a DOS hosted version of the simulator to be built. NOTE: The FP
is still not complete, since round-to-nearest and round-to-zero have
not been implemented generically.
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.
