247fccdeb5 Add ABFD argument to sim_open call. Pass through to sim_config so
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.

09e142d5a2 * interp.c (sim_resume): Add missing case in big switch
statement (for extb instruction).

003c91bec4 * interp.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.
        (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.

4df7aeb3c5 * interp.c (dispatch): Make this an inline function.
* simops.c (syscall): Use callback->write regardless of
        what file descriptor we're writing too.

b07a1e78c5 * interp.c (load_mem_big): Remove function. It's now a macro
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.

234a9a49cf * interp.c (load_mem): If we get a load from an out of range
address, abort.
        (store_mem): Likewise for stores.
        (max_mem): New variable.

baa83bcc80 * interp.c: Improve hashing routine to avoid long list
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.

6cc6987e1e * Makefile.in (SIM_OBJS): Add sim-load.o.
* interp.c (sim_kind, myname): New static locals.
	(sim_open): Set sim_kind, myname.  Ignore -E arg.
	(sim_load): Return SIM_RC.  New arg abfd.  Call sim_load_file to
	load file into simulator.  Set start address from bfd.
	(sim_create_inferior): Return SIM_RC.  Delete arg start_address.

7c52bf32f2 * interp.c: Delete unused global variable "OP".
(sim_resume): Remove unused variable "opcode".
        * simops.c: Fix some uninitialized variable problems, add
        parens to fix various -Wall warnings.
Fixing assorted -Wall problems.

d252301029 * gencode.c (write_header): Add "insn" and "extension" arguments
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.
