* compile.c: Don't include "wait.h".
(sim_resume): Use local SIM_WIFEXITED and SIM_WIFSIGNALED macros
instead of WIF* from host.
with sim/common.
* configure.in: check for sys/param.h
* compile.c: #ifdef HAVE_SYS_PARAM_H.
#define SIGTRAP for wingdb.
(sim_resume): poll keyboard at least once per call.
(sim_resume): use host_callback instead of printf for syscall
output.
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.
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).
* compile.c (sim_kind, myname): New static locals.

* Make-common.in (CSEARCH): Do not include the gdb directory in
the search path.

SIM_WARNING): Drop, requiring the simulator specific Makefile.in
to explicitly incorporate these.

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.

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.

* compile.c (sim_resume, case "O_NOT"): Use ONOT instead
of OSHIFTS.
(ONOT): Define.
(sim_resume, shift/rotate cases): Add support for shift/rotate
by two bits.
(OSHIFTS): Corresponding changes.
Handling more H8/S ops.
of holding them in "abs". Handle ABS8MEM memory references aka
8-bit area. Replace ABSMOV references with ABS8MEM.
So we've got a chance of simulating something like btst #0,@40:8 correctly.
hmse.
bfd/hosts/*.h file or bfd/config/*.mh file. Call AC_PROG_CC and
AC_PROG_RANLIB. Substitute in values for CFLAGS, HDEFINES and AR.
