1998-12-30* eCos->devo merge; am30 sanitization tags removedFrank Ch. Eigler1-113/+254
1998-12-29 Frank Ch. Eigler <fche@cygnus.com> * Makefile.in (WITH_COMMON_OBJS): Build also dv-sockser.o. * interp.c (sim_open): Add stub mn103002 cache control memory regions. Set OPERATING_ENVIRONMENT on "stdeval1" board. (mn10300_core_signal): New function to intercept memory errors. (program_interrupt): New function to dispatch to exception vector (mn10300_exception_*): New functions to snapshot pre/post exception state. * sim-main.h (SIM_CORE_SIGNAL): Define hook - call mn10300_core_signal. (SIM_ENGINE_HALT_HOOK): Do nothing. (SIM_CPU_EXCEPTION*): Define hooks to call mn10300_cpu_exception*(). (_sim_cpu): Add exc_* fields to store register value snapshots. * dv-mn103ser.c (*): Support dv-sockser backend for UART I/O. Various endianness and warning fixes. * mn10300.igen (illegal): Call program_interrupt on error. (break): Call program_interrupt on breakpoint Several changes from <janczyn@cygnus.com> and <cagney@cygnus.com> merged in: * dv-mn103int.c (mn103int_ioctl): New function for NMI generation. (mn103int_finish): Install it as ioctl handler. * dv-mn103tim.c: Support timer 6 specially. Endianness fixes.

* interp.c (board): Rename am32 to stdeval1 as this is the name consistently used to refer to the mn1030002 board.
1998-06-18Thu June 18 14:37:14 1998 Joyce Janczyn <janczyn@cygnus.com>Joyce Janczyn1-1/+4
* interp.c (sim_open): Fix typo in address of EXTMD register (0x34000280, not 0x3400280).
1998-06-08 * interp.c: (mn10300_option_handler): New function parses argumentsJoyce Janczyn1-114/+156
using sim-options. start-sanitize-am30 * (board): Add --board option for specifying am32. * (sim_open): Create new timer and serial devices and control configuration of other am32 devices via board option. end-sanitize-am30
1998-03-27Add sanitize-am30 markers. Keep details of AM30 implementation ofAndrew Cagney1-24/+30
mn10300 out of the public eye. Do something with top-level cgen directory.
1998-03-25* interp.c (sim_open): Create second 1mb memory region at 0x40000000.Andrew Cagney1-150/+119
(sim_open): Create a device tree. (sim-hw.h): Include. (do_interrupt): Delete, needs to use dv-mn103cpu.c * dv-mn103int.c, dv-mn103cpu.c: New files.
1998-03-25Pacify GCC.Andrew Cagney1-3/+4
1998-03-24Add code to support building mn10300 simulator with the common simulatorJoyce Janczyn1-79/+398
framework.
1997-08-26Flush defunct sim_kill.Andrew Cagney1-7/+0
1997-08-25Add ABFD argument to sim_open call. Pass through to sim_config soAndrew Cagney1-3/+9
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.
1997-05-22 * interp.c (sim_resume): Add missing case in big switchJeff Law1-0/+1
statement (for extb instruction).
1997-05-20 * interp.c: Replace all references to load_mem and store_memJeff Law1-85/+23
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.
1997-05-19 * interp.c (dispatch): Make this an inline function.Jeff Law1-1/+1
* simops.c (syscall): Use callback->write regardless of what file descriptor we're writing too.
1997-05-18 * interp.c (load_mem_big): Remove function. It's now a macroJeff Law1-26/+24
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.
1997-05-16 * interp.c (load_mem): If we get a load from an out of rangeJeff Law1-0/+11
address, abort. (store_mem): Likewise for stores. (max_mem): New variable.
1997-05-06 * interp.c: Improve hashing routine to avoid long listJeff Law1-241/+505
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.
1997-04-17 * Makefile.in (SIM_OBJS): Add sim-load.o.David Edelsohn1-34/+146
* 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.
1996-12-06 * interp.c: Delete unused global variable "OP".Jeff Law1-3/+1
(sim_resume): Remove unused variable "opcode". * simops.c: Fix some uninitialized variable problems, add parens to fix various -Wall warnings. Fixing assorted -Wall problems.
1996-12-06 * gencode.c (write_header): Add "insn" and "extension" argumentsJeff Law1-11/+217
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.
1996-11-25 * Makefile.in, config.in, configure, configure.in: New files.Jeff Law1-0/+394
* gencode.c, interp.c, mn10300_sim.h, simops.c: New files. Skeleton mn10300 simulator
