* (mul64): Simplify calculation of negative result.
* (div64): New helper function for 64-bit division.
* (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
and UDIVCC.
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.
(start_address): New static local.
(sim_load): Return SIM_RC. New arg abfd. Set start_address from bfd.
(sim_create_inferior): Return SIM_RC. Delete arg start_address.
* 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.
* Makefile.in: Only link in -ltermcap if it exists.
* erc32.c: Update to version 2.6a. Fix uart handling.
* exec.c: Update to version 2.6a. Add sparclite support.
* float.c: Update to version 2.6a. Convert comments to
preprocessor warnings. Add __setfpucw() for i385 hosts so floating
point exceptions work.
* func.c: Update to version 2.6a. Fix uart handling, add support
for user error traps.
* help.c: Update to version 2.6a. Add help note on user error
traps.
* interf.c: Update to version 2.6a. Fix uart handling, and add
sparclite support.
* examples/gccx: Use sparclite cross compiler, not native gcc.
* examples/srt0.S: Use "mov" rather than "wr" for manipulating
the psr register.
(SIM_{OBJS,EXTRA_LIBS,EXTRA_LIBDEPS,EXTRA_ALL,EXTRA_INSTALL}): Define.
(SIM_{EXTRA_CLEAN,EXTRA_CFLAGS}): Define.
* configure.in: Simplify using macros in ../common/aclocal.m4.
Call AC_CHECK_HEADERS(stdlib.h).
* configure: Regenerated.
* config.in: New file.
* func.c (sim_set_callbacks): Delete, moved to
* interf.c (sim_set_callbacks): here.
(sim_callback): New global.
Rewrite all calls to printf_filtered to go through callback.
(sim_size,sim_trace): New functions.
(sim_{insert,remove}_breakpoint): #if 0 out.
* sis.c: #include "config.h". #include <stdlib.h> if present.
(main): Coerce fprintf arg to INIT_DISASSEMBLE_INFO to fprintf_ftype.
* sis.h: #include "callback.h".
sis.h: Get rid of all uses of long long's.
* (close_port read_uart write_uart uarta_tx): Don't seg fault
when can't open pty's.
* exec.c: Add two new instructions: smul, and divscc.
* interf.c (flush_windows): New routine to flush the register
windows out to the stack just before returning to GDB. Makes
backtraces work much better.
