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.
(sim_stop_reason): If State.exited is nonzero, then indicate that
the simulator exited instead of stopped.
* mn10300_sim.h (struct _state): Add exited field.
* simops.c (syscall): Set State.exited for SYS_exit.
Fixes problem found bin Felix.
with references to load_byte, load_half, load_3_byte, load_word
and store_byte, store_half, store_3_byte, store_word.
(INLINE): Delete definition.
(load_mem_big): Likewise.
(max_mem): Make it global.
(dispatch): Make this function inline.
(load_mem, store_mem): Delete functions.
* mn10300_sim.h (INLINE): Define.
(RLW): Delete unused definition.
(load_mem, store_mem): Delete declarations.
(load_mem_big): New definition.
(load_byte, load_half, load_3_byte, load_word): New functions.
(store_byte, store_half, store_3_byte, store_word): New functions.
* simops.c: Replace all references to load_mem and store_mem
with references to load_byte, load_half, load_3_byte, load_word
and store_byte, store_half, store_3_byte, store_word.
defined elsewhere.
(compare_simops): New function.
(sim_open): Sort the Simops table before inserting entries
into the hash table.
* mn10300_sim.h: Remove unused #defines.
(load_mem_big): Define.
Another 20% so performance improvement for the mn10300 simulator.
traversals for common instructions. Add HASH_STAT support.
Rewrite opcode dispatch code using a big switch instead of
cascaded if/else statements. Avoid useless calls to load_mem.
(REG_MDRQ): Define.
* simops.c: Don't abort for trap. Add support for the extended
instructions, "getx", "putx", "mulq", "mulqu", "sat16", "sat24",
and "bsch".
o Provide poll_quit callback to simulators
so that they can poll for SIGINT on
clueless OS's.
o Add sim_stop to simulators so that clients
can request a halt (eg gdbtk's STOP button)
Works for PPC!
o Re-arange remote-sim.c so that the
hard work is moved from gdbsim_resume()
to gdbsim_wait() (where it should be).
Somewhat simplify "sub" instructions.
Correctly sign extend operands for "mul". Put the correct
half of the result in MDR for "mul" and "mulu".
Implement remaining instructions.
Tweak opcode for "syscall".
* Make-common.in (CSEARCH): Do not include the gdb directory in
the search path.
* Make-common.in (SIM_ENDIAN, SIM_HOSTENDIAN, SIM_INLINE,
SIM_WARNING): Drop, requiring the simulator specific Makefile.in
to explicitly incorporate these.
* aclocal.m4 (--enable-sim-alignment); New option. Strongly
specify the alignment restrictions of the target architecture -
without this option all alignment restrictions are accomodated.
(--enable-sim-assert): New option. Conditionally compile in
assertion statements.
(--enable-sim-float): New option. Strongly specify the target's
floating point support.
(--enable-sim-hardware): New option. Specify the hardware devices
included in the simulation.
(--enable-sim-packages): New option. Specify the hardware
packages included in the simulation.
(--enable-sim-regparm): New option. Specify that parameters be
passed in registers instead of on the stack.
(--enable-sim-reserved-bits): New option. Specify that reserved
bits within an instruction are are correctly set.
(--enable-sim-smp): New option. Specify the level of SMP support
to be included in the simulator.
(--enable-sim-stdcall): New option. Specify an alternative
function call convention.
(--enable-sim-xor-endian): New option. Configure xor-endian
support used by some targets to implement bi-endian support.
scheme which is more compatible with WinGDB builds.
* configure.in: Improve comment on how to run autoconf.
* configure: Re-run autoconf to get new ../common/aclocal.m4.
* Makefile.in: Use autoconf substitution to install common
makefile fragment.
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!
