1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>

        * exec.c (dispatch_instruction): 
        Correct the sense of the
                  if (!sparclite) {
                     sregs->trap = TRAP_UNIMP;
                     break;
                  }
        clause that has been pasted around: it's correct in the SCAN and
        DIVScc (divide step) cases (where it was probably originally
        written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
        ie. instructions only in the SPARC V8 or SPARClite 86x
        architectures.  It was also present when not required for SMUL,
        SMULcc, UMUL, UMULcc instructions that are present in all
        architectures.

1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>

        * interf.c (run_sim): Fix a bug in the main loop's handling of
        annulled delay slot instructions.  There is precedent for this
        change; the _other_ main loop in sis.c gets it right according to
        my reading of the code.

        The bug is: if an interrupt happens when the next instruction
        (at sregs->pc) is annulled, the trap is taken (by execute_trap())
        with the current values of PC and NPC, so when the trap returns,
        the annulled instruction is indeed executed.  Another giveaway is
        that the annul flag is cleared in execute_trap(): the information
        is demonstrably discarded.

        The solution is: perform annulling before looking for traps, in
        fact it's neater to do annulling, see if there's an interrupt and
        if not, do the instruction, then handle traps be they generated by
        interrupts pending or by the instruction we might just have done.
        That's what the sis.c one does.

1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>

        * sis.h: Add asr17 register for support of SparcLITE (at least the
        Hitachi ones I find before me)

        * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
        sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
        Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
        (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
        (init_regs): Initialize y and asr17.
        NB: In instruction-set space, the Y register is asr0; the
        instructions have different names for human reasons only.

        * sis.c:
        * interf.c: Set boolean mode variable dumbio if invoked with
        argument "-dumbio" and mention it of verbose.
        * erc32.c: if "dumbio" is set, do not assume that there is a
        terminal type device attached to stdin/stdout.  Do not set
        buffering or mess with tcsetattr or do any read operations in
        order to make UART interrupts; not input data is supported.
        This is necessary to allow the sim to be used within the eCos
        testing infrastructure where stdin/stdout are pipes to a TCL
        program; the sim hangs otherwise.

Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>

        mememory_read and memory_write.

        * examples/srt0.S: Use "mov" rather than "wr" for manipulating
        the psr register.

Mon Nov 25 08:28:10 1996  Fred Fish  <fnf@cygnus.com>

        * Makefile.in (run.o): Remove this rule, it hides the one in
        ../common/Make-common.in that correctly references the source
        in the sibling ../common directory.

Wed Nov 20 01:30:12 1996  Doug Evans  <dje@canuck.cygnus.com>

        there either...).

        * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't
        necessary.

        * 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.

Wed Jun 26 12:19:11 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)

        * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,

        Make $(tooldir) and $(tooldir)/bin.

Mon Jun  3 12:33:38 1996  Ian Lance Taylor  <ian@cygnus.com>

        * Makefile.in (end.h): Use explicit ./ when running end.

Sun May 19 21:05:31 1996  Rob Savoye  <rob@chinadoll.cygnus.com>

        * func.c(bfd_load): Don't try to print the filename if the pfbd is
        NULL.
        * interf.c(sim_load): Pass the whole string, not just the first
        byte.

Version 2.1 26-02-96
--------------------
 
* Fixed bug in "go" command.
 
version 2.0 05-02-96
--------------------

* Fixed bug in interrupt force register (erc32.c).

* Change file load function to use bfd_openr.

* SIS should now be endian independent.

version 1.8 24-11-95
--------------------

* Fixed FPU timing - some sequences of FPU instructions did not calculate
  the resource dependencies right.

* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
  but no FPU trap is generated.

version 1.7.1 31-10-95
--------------------

* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
  the FPU stays in execute mode.

* Corrected JMPL and RETT timing (these instructions takes two cycles).


version 1.7 25-10-95
--------------------

* Interrupt during annuled instruction corrupted return address - fixed.


version 1.6.2 25-10-95
--------------------

* Added -DFAST_UART to Makefile
 

version 1.6.1 24-10-95
--------------------
 
* Fixed bug in STDFQ which caused bus error


version 1.6 02-10-95
--------------------
 
* Modified srt0.s to include code that initiates registers in IU and FPU
  and initializes the data segment. The simulator 'load' command does not
  longer initialize the data segment!

* Corrected MEC timer operation; scalers now divide the frequency by 
  (scaler_value + 1).

* MEC breakpoints are not checked during store operation


version 1.5 14-09-95
--------------------

* Fixed some bugs in the cycle counting for IU & FPU instructions.

* Fixed bug that allowed an annuled instruction to cause memory exception.

* The *ws parameter in mem.c should now contain the number of waitstates
  required by the memory access (was total number of cycles).

* The supplied srt0.s now clears the BSS (thanks Joel).

version 1.4 22-08-95
--------------------

* Added a '-g' switch to enable/disable the GNU readline(), which cause
some problems on solaris 2.x machines.

* Enabled MEC watchpoint and breakpoint function to mem.c. Performance 
may suffer a bit ...

NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.

version 1.3 26-07-95
--------------------

* Fixed bug in mulscc instruction (how could that ever have worked?)

* Fixed bug in UART B (flushed characters on UART A), thanks Paul.

version 1.2 13-07-95
--------------------

* Fixed bug in interrupt handling (wrong interrupt selected when more that
one interrupt pending)

* Fixed updating of condition codes during logical instructions (carry and
overflow were not reset)

* Fixed bug in WRTBR (tt field was wrongly over-written)

version 1.1 07-07-95
--------------------

* Fixed several bugs in the interrupt handler and callback routines.
