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.
Use the bfd-processor name in the sim-engine switch.
Add nr_cpus argument to sim_engine_run.
tic80, v850, d30v, mips, common:
Update
mips: Fill in bfd-processor field of model records so that
they match ../bfd/archures.
MIPS simulator so that correctly writes the value of CIA back int PC
(the global previously used) when the simulation halts.
Fix implementation of DELAY_SLOT and NULLIFY_NEXT_INSTRUCTION macros.
calls) and sim_open so that they uses the virtual memory data transfer
functions sim_read & sim_write. This eliminates all code (other than
in load_memory & store_memory) that makes assumptions about the
implementation of the underlying memory model.
When address translation of insn fetch fails raise exception immediatly.
Use address_word as type of all address variables (instead of unsigned64),
the former is configured as either 32 or 64 bit type.
Always compile fpu code (no #if has fpu)
Add file sim-hload.c - generic load for hardware only simulators.
Review each simulators sim_open, sim_load, sim_create_inferior so that
they more closely match required behavour.
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.
* interp.c: #include bfd.h.
(target_byte_order): Delete.
(sim_kind, myname, big_endian_p): New static locals.
(sim_open): Set sim_kind, myname. Move call to set_endianness to
after argument parsing. Recognize -E arg, set endianness accordingly.
(sim_load): Return SIM_RC. New arg abfd. Call sim_load_file to
load file into simulator. Set PC from bfd.
(sim_create_inferior): Return SIM_RC. Delete arg start_address.
(set_endianness): Use big_endian_p instead of target_byte_order.
(SignalException): Pass floating point cases to mips16_entry.
(ValueFPR): Don't restrict fmt_single and fmt_word to even
registers.
(StoreFPR): Likewise. Also, don't clobber fpr + 1 for fmt_single
or fmt_word.
(COP_LW): Pass fmt_word rather than fmt_uninterpreted to StoreFPR,
and then set the state to fmt_uninterpreted.
(COP_SW): Temporarily set the state to fmt_word while calling
ValueFPR.
(mips16_entry): New static function.
(SignalException): Look for mips16 entry and exit instructions.
(simulate): Use the correct index when setting fpr_state after
doing a pending move.
relative operands.
(build_instruction): Call JALDELAYSLOT rather than DELAYSLOT for a
jal instruction.
* interp.c (simJALDELAYSLOT): Define.
(JALDELAYSLOT): Define.
(INDELAYSLOT, INJALDELAYSLOT): Define.
(simulate): Clear simJALDELAYSLOT when simDELAYSLOT is cleared.
* gencode.c (build_instruction, case JUMP): Truncate PC to 32 bits.
* interp.c (CHECKHILO): Define away.
(simSIGINT): New macro.
(membank_size): Increase from 1MB to 2MB.
(control_c): New function.
(sim_resume): Rename parameter signal to signal_number. Add local
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.
