* interp.c, mips.igen: all 5 DEADC0DE situations now have sim_io_eprintf
calls, conditional on the simulator being in verbose mode.
1998-12-29 Frank Ch. Eigler <fche@cygnus.com>
* interp.c (sim_open): Allocate jm3904 memory in smaller chunks.
(load_word): Call SIM_CORE_SIGNAL hook on error.
(signal_exception): Call SIM_CPU_EXCEPTION_TRIGGER hook before
starting. For exception dispatching, pass PC instead of NULL_CIA.
(decode_coproc): Use COP0_BADVADDR to store faulting address.
* sim-main.h (COP0_BADVADDR): Define.
(SIM_CORE_SIGNAL): Define hook to call mips_core_signal.
(SIM_CPU_EXCEPTION*): Define hooks to call mips_cpu_exception*().
(_sim_cpu): Add exc_* fields to store register value snapshots.
* mips.igen (*): Replace memory-related SignalException* calls
with references to SIM_CORE_SIGNAL hook.
* dv-tx3904irc.c (tx3904irc_port_event): printf format warning
fix.
* sim-main.c (*): Minor warning cleanups.
Set mips_fpu, and mips_fpu_bitsize.
Set sim_gen, and sim_igen_machine.
* configure: Rebuild.
* mips.igen (BC1): Renamed to BC1a and BC1b to avoid conflicts.
* sim-main.h (SizeFGR): Handle TARGET_ENABLE_FR.
It is not yet properly tested.

* dv-tx3904tmr.c: New file - implements tx3904 timer.
* dv-tx3904{irc,cpu}.c: Mild reformatting.
* configure.in: Include tx3904tmr in hw_device list.
* configure: Rebuilt.
* interp.c (sim_open): Instantiate three timer instances.
Fix address typo of tx3904irc instance.
* Followup patch for SCEI PR 15853
* First check-in of TX3904 interrupt controller devices for ECC. [sanitized]
* First implementation of MIPS hardware interrupt emulation.
Mon May 18 18:22:42 1998 Frank Ch. Eigler <fche@cygnus.com>
* configure.in (SIM_AC_OPTION_HARDWARE): Added common hardware
modules. Recognize TX39 target with "mips*tx39" pattern.
* configure: Rebuilt.
* sim-main.h (*): Added many macros defining bits in
TX39 control registers.
(SignalInterrupt): Send actual PC instead of NULL.
(SignalNMIReset): New exception type.
* interp.c (board): New variable for future use to identify
a particular board being simulated.
(mips_option_handler,mips_options): Added "--board" option.
(interrupt_event): Send actual PC.
(sim_open): Make memory layout conditional on board setting.
(signal_exception): Initial implementation of hardware interrupt
handling. Accept another break instruction variant for simulator
exit.
(decode_coproc): Implement RFE instruction for TX39.
(mips.igen): Decode RFE instruction as such.
start-sanitize-tx3904
* configure.in (tx3904cpu,tx3904irc): Added devices for tx3904.
* interp.c: Define "jmr3904" and "jmr3904debug" board types and
bbegin to implement memory map.
* dv-tx3904cpu.c: New file.
* dv-tx3904irc.c: New file.

the stand-alone executable.
[in ChangeLog.sky:]
* sky-gpuif.c (call_gs): Call properly into GPU2 library if
configured --with-sim-gpu2. Use SKY_GPU2_REFRESH symbol as
placeholder for future GPU2-refresh policy.
[in ChangeLog:]
* Makefile.in (MIPS_EXTRA_LIBS, SIM_EXTRA_LIBS): Added
configurable settings for stand-alone simulator.
start-sanitize-sky
* configure.in: Added --with-sim-gpu2 option to specify path of
sky GPU2 library. Triggers -DSKY_GPU2 for sky-gpuif.c, and
links/compiles stand-alone simulator with this library.
* interp.c (MEM_SIZE): Increased default sky memory size to 16MB.
end-sanitize-sky
* configure.in: Added X11 search, just in case.
* configure: Regenerated.
little struct.
interp.c: Update. Also add floating point Max/Min functions.
mips.igen: Remove r5900 tag from any floating point instructions.
r5900.igen: Rewrite. Implement *all* floating point insns (except ld/st).
r5400.igen: Tag mdmx functions as being mdmx specific.
update v850, tic80 and mips simulators.
IGEN - Prepend prefix to more generated symbols and macros
(idecode_issue, instruction_word).
IGEN - Add -Wnowith option to supress warnings about word size
inflicts in input files.
MIPS - Clean up Makefile.in, m16.igen, m16.dc (new), m16run.c (new) so
that a mips16 simulator built using IGEN can be compiled.
that image properties such as endianness can be checked.
More strongly document the expected behavour of each of the sim_*
interfaces.
Add default endian argument to simulator config macro
SIM_AC_OPTION_ENDIAN. Use in sim_config.
