2000-12-12  Geoffrey Keating

        * sim_calls.c: Doc fix.
        (sim_fetch_register, sim_store_register): Call

1999-02-01  Jim Blandy  
 
        Make the simulator compatible with the MPC750.  It would be nicer
        to make this a real multi-sim, but that's more work than we have
        time for.
        * emul_generic.c (emul_add_tree_options): Only require strict
        alignment if it was explicitly requested at configuration time.
        Don't make it the default for little-endian machines.
        * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
        MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
        THRM2, THRM3): Plop in the MPC750 SPR registers.
        (DABR): This is weird.  This was HID5, but the PPC spec says this
        should be DABR; why did some random processor use it for something
        else?  The HID5 entry dates back to the original checkin of the
        simulator code in 1995, so remove it.
        * sim_calls.c (register_names): Delete this; since the user can
        now change GDB's list of register names dynamically, we can't
        pretend there's a static mapping here.
        (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
        function to get the register name.  That ought to be accurate.
        However, we're changing a compile-time dependency (using the
        REGISTER_NAMES macro) into a link- and run-time dependency
        (calling REGISTER_NAME, which happens to be a function call on the
        PPC).
 
1999-01-22  Jim Lemke 
 
        * igen.c(gen_semantics_[ch]): setup/use of new option
        (-o mpc860c0[=n]).
        interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
        ppc-instructions(the four branch insn groups): detect problematic br's.
        psim.c(is_num - added, psim_options): Parse and init new option.
        These changes are currently under #ifdef WITH_OPTION_MPC860C0.
 
1998-12-01  Ken Raeburn  
 
        * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

        poll the external environment.
 
1998-11-19  Michael Meissner  
 
        * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
        fractional type, so that quiet NaN's aren't treated like
        Infinities.
 
Mon Sep 28 09:42:45 1998  Drew Moseley  
 
        * table.c (table_open): For cygwin hosts, we need to use the
        return value from the read routine as the number of bytes to
        process.  This apparently is due to text-mode vs binary-mode.  If
        the mounts are done text-mode, then the size returnedby fstat()
        may be different than the number of bytes "read" in text mode.
 
Sun Oct  4 00:50:47 1998  Felix Lee  
 
        * emul_netbsd.c (do_open): fix order-of-evaluation problem.

        * configure: Regenerate.
        * emul_{netbsd,unix}.c (toplevel): No longer try to include
        sys/mount.h. It conflicts on Linux when gnu libc2 is used.
 
Tue May 12 12:10:33 PDT 1998  James Ingham  
 
        * Makefile.in: The run target depended on a target psim$(EXEEXT),
        but there was no such target, only plain psim.  So I changed the
        run target to depend on psim.
 
Sat May  2 01:10:12 1998  Stu Grossman  
 
        * aclocal.m4:  Remove defs of AM_EXEEXT and AM_CYGWIN32.  These are
        now defined in ../common/aclocal.m4, and the double definition causes
        problems with AC_SUBST of EXEEXT.
        * configure:  Regenerate.

        flush_stdout.
 
Fri Sep 26 09:50:29 1997  Andrew Cagney  
 
        * ppc-instructions (sraw, slw, srw): From Charles Lefurgy, Fix
        mask extracting shift amount. Correctly condition for setting XER
        in sraw.
        (ldhau): From Johannes Reisinger, update rA after load.

        Should be delaying everything related to ihandle creation until
        after the rest of the tree has been established.
 
        * device.c (device_find_ihandle_runtime_property): Update.
        (device_add_ihandle_runtime_property): Update.

        works for normal and boolean table entries.
 
        * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
        valid.  Handle this just like *_{read,write}_register now handles

        max iterations exceeded.
 
        * gen-idecode.c: Re-work the table lookup code so that it assumes
        that the entry is a leaf by default.  Simplify the boolean table
        entry code so that it involves a mask + test instead of shift +
        shift + mask + test.
 
        * gen-idecode.c: Correct generated igen body so that it no drops
        or doubles clock interrupts.

        fields.
 
        * misc.c (name2i): Possibly abort if an invalid name is
        encountered.
        * ld-decode.c: Abort if the table type isn't found.
 
Wed Jan 29 12:14:19 1997  Andrew Cagney  
 
        * When performance monitoring is disabled, it is still possible to
        determine the simulation speed by looking at the number of elapsed
        ticks recorded by the event queue.
 
        * psim.c (psim_write_register, psim_read_register): Force the cpu
        to zero when it is either of `-1' or `nr_cpus'.  In both cases the
        next cpu would be zero any way.
 
        * mon.c (mon_print_info): If possible, print the system cycle
        performance.  This is an indication of the number of instructions
        per second.
 
Wed Jan 29 12:14:19 1997  Andrew Cagney  
 
        * The code to allow an event queue to be updated during a signal
        was missing.  For main.c, a cntrl-c simulation termination wasn't
        handled cleanly.
 
        * The simulation would not correctly restart if an event requested
        that the simulation be halted.
 
        * psim.c (psim_options): Add hack to -i option to optionally
        include a level vis -i2.
        (psim_usage): Document.
 
        * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
        cntrl-c occures schedule an event to halt the simulation.
        (main): Catch CNTRL-C signals with the function cntrl_c.
 
        * events.c (event_queue_process): Mask interrupts while

        the processing state when processing has started.  Adjust code
        so that it is tolerant of halts.
        (event_queue_init): Start the event queue out with processing
        false.
        (event_queue_tick): Check that processing isn't still being
        performed.
 
        * gen-idecode.c (print_run_until_stop_body): Call

        * psim.c (psim_halt): Handle an event halting the simulation.
        * psim.c (psim_init): Adjust initial cpu - == -1 - to match
        reworked idecode.
 
Wed Jan 29 12:14:19 1997  Andrew Cagney  
 
        * ppc-opcode-complex: Correct typo - was expanding ORA instead of
        RA.  Based on instruction frequency stats, expand additional
        instructions.
        * ppc-instructions: Change all `RA == 0' to RA_is_0.
 
        * ppc-opcode-stupid: Move all but the basic table in -complex into
        here.  Update to new format.
 
        * Makefile.in (tmp-defines): New target. Force defines.h to always
        be built.  Hence get ppc-opcode-goto to build.

        * hw_com.c (hw_com_instance_read, hw_com_instance_write):
        Implement.
 
Thu Jan 23 09:07:26 1997  Andrew Cagney  
 
        * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
        to be initialized independant of the rest of the simulation
        initalization.  Otherwize a trace option explictly set from gdb
        could be overridden by hw_trace.
 
        * psim.c (psim_options): Clarify reason why the trace ioctl occures.
 
        * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
        debug.c.  It could be much simpler.
 
Thu Jan 23 09:07:26 1997  Andrew Cagney  
 
        * Some devices support removable media.  Add hooks to the disk
        device so that it supports this.

        (device_init_runtime_properties): Update.
 
        * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
        media.  If no file image is specified, use the next one in the
        image property list.
        (hw_disk_init_address): Change the file property so that it is a
        string array - use the first entry for the initial file image.
 
        * tree.c (print_string_aray_property): New function - print a
        string array.
        (print_properties): Adjust.
        (print_string): Write a string, handling double quotes.
 
        * device.h: Define an ioctl to `change-media' with an optional new
        media image.

        * psim.c (psim_command): New function, parse more complex psim
        commands such as "change-media" and "trace".

Wed Jan 22 09:38:33 1997  Andrew Cagney  
 
        * For expressions like (RA == 0) that are entered in to the cache
        as RA_is_0. If possible generate the result of the expression so
        that the compiler gets a better chance of eliminating dead
        branches.
 
        * gen-icache.c (print_icache_extraction): For a cache entry of
        the form _is_ where it is a boolean field, generate
        the result of the expression instead of the expression its self.
        (print_icache_body): Remove code that was looking for *_is_0 and
        then generating corresponding definitions.
 
        * gen-icache.c (print_icache_struct): If there is no cache, do not
        output expressions in idecode.h file.
 
        * gen-icache.c (print_icache_body): Output them here.
 
        * ppc-opcode-complex: Clarify constant values for SPR==LR register
        expansion.
 
        * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
 
Wed Jan 22 12:24:52 1997  Andrew Cagney  
 
        * The code that put values in and extracted values from the cache
        was too compilicated.  The cache table did not allow values to be
        computed from cache entries.  #defines could only be used when a
        cache was present, remove the restriction.
 
        * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
        scratch variable is defined when a cache entry is beinf
        filled. Change the definition of a COMPUTE variable to be defined
        when the cache entry is being used.
        * gen-icache.c: Update.
 
        * ld-cache.h, ld-cache.c: Change field names so that their meaning
        is more obvious.  old_name->field_name, new_name->derived_name.
        * gen-icache.c: Update
 
        * gen-icache.h, gen-icache.c (print_icache_body): Make the three
        different types of cache code - put into cache, extract from
        cache, no cache - an explicit argument to print_icache_body.
        * gen-icache.c (print_icache_extraction): Ditto.
 
        * gen-semantics.c (print_c_semantic): Update use.
        * gen-idecode.c (print_jump_insn): Update use.
        * gen-icache.c (print_icache_function): Update use.
 
        * igen.c (main): Change 'R' option so that it does not force the
        cache.
 
        * configure.in (enable-sim-icache): Clarify description.  Make
        #define one of the defaults regardless of the cache.  Probably
        should revamp and add a separate option.
 
Tue Jan 21 13:26:10 1997  Andrew Cagney  
 
        * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
        partition numbering.

        partition selection is supported.
 
Mon Jan 20 11:20:15 1997  Andrew Cagney  
 
        * The cap object was retaining a reference to the instance of a
        device after it was deleted. Instead add and remove cap's from the
        cap db as they are created and deleted.  This ensuring that a

        * device.c (external_to_device) : New function that provides a
        standard mapping between a devices internal representation (a
        pointer) and its external (or what is passed to a client)
        representation (a phandle).  Implement using the cap object
        attached to the root node.
 
        * device.c (device_to_external) : Ditto
        * device.c (external_to_device_instance) : Ditto but for ihandle
        and device instance.
        * device.c (device_instance_to_external) : Ditto
 
        * Makefile (device.o): Add dependency on cap.
 
        * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
        needing to translate between internal and external representations
        changed to use the external_to_device et.al. device operations.
        * emul_chirp.c (chirp_emul_*) : Ditto
 
        * Makefile (emul_chirp.o): Remove dependency on cap
 
Sat Jan  6 10:13:26 1996  Andrew Cagney - aka Noid  
 
        * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
        on OpenBoot note section.
 
Fri Jan  5 20:28:53 1996  Andrew Cagney  
 
        * emul_generic.c (emul_write_buffer): Use vm faulting byte
        read/write calls for buffer transfers.  This will cause a fault to
        occure if the transfer fails.  CHRP catches the fault while the
        others suffer the consequences.
        (emul_read_buffer): Ditto.
        (emul_write_word): Ditto.
        (emul_read_word): Ditto.
        (emul_read_string): Ditto.
 
Fri Jan  5 18:55:34 1996  Andrew Cagney  
 
        * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
        emul_generic (emul_blr_instruction): Use a real blr instruction to
        return from a client service call.
 
        * emul_chirp.c (services): Add all OpenBoot services to table.
 
        * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
        (emul_chirp_create) : Use names instead of numbers for
        instructions being stored in memory.
