128
 
129
1999-02-11  Hugo Tyson  
130
 
131
        * exec.c (dispatch_instruction):
132
        Correct the sense of the
133
                  if (!sparclite) {
134
                     sregs->trap = TRAP_UNIMP;
135
                     break;
136
                  }
137
        clause that has been pasted around: it's correct in the SCAN and
138
        DIVScc (divide step) cases (where it was probably originally
139
        written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
140
        ie. instructions only in the SPARC V8 or SPARClite 86x
141
        architectures.  It was also present when not required for SMUL,
142
        SMULcc, UMUL, UMULcc instructions that are present in all
143
        architectures.
144
 
145
1999-01-25  Hugo Tyson  
146
 
147
        * interf.c (run_sim): Fix a bug in the main loop's handling of
148
        annulled delay slot instructions.  There is precedent for this
149
        change; the _other_ main loop in sis.c gets it right according to
150
        my reading of the code.
151
 
152
        The bug is: if an interrupt happens when the next instruction
153
        (at sregs->pc) is annulled, the trap is taken (by execute_trap())
154
        with the current values of PC and NPC, so when the trap returns,
155
        the annulled instruction is indeed executed.  Another giveaway is
156
        that the annul flag is cleared in execute_trap(): the information
157
        is demonstrably discarded.
158
 
159
        The solution is: perform annulling before looking for traps, in
160
        fact it's neater to do annulling, see if there's an interrupt and
161
        if not, do the instruction, then handle traps be they generated by
162
        interrupts pending or by the instruction we might just have done.
163
        That's what the sis.c one does.
164
 
165
1999-01-20  Hugo Tyson  
166
 
167
        * sis.h: Add asr17 register for support of SparcLITE (at least the
168
        Hitachi ones I find before me)
169
 
170
        * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
171
        sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
172
        Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
173
        (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
174
        (init_regs): Initialize y and asr17.
175
        NB: In instruction-set space, the Y register is asr0; the
176
        instructions have different names for human reasons only.
177
 
178
        * sis.c:
179
        * interf.c: Set boolean mode variable dumbio if invoked with
180
        argument "-dumbio" and mention it of verbose.
181
        * erc32.c: if "dumbio" is set, do not assume that there is a
182
        terminal type device attached to stdin/stdout.  Do not set
183
        buffering or mess with tcsetattr or do any read operations in
184
        order to make UART interrupts; not input data is supported.
185
        This is necessary to allow the sim to be used within the eCos
186
        testing infrastructure where stdin/stdout are pipes to a TCL
187
        program; the sim hangs otherwise.
188
 
189
Thu Jul 23 07:17:03 1998  Mark Alexander  
190
 
191
        * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
192
 
193
Tue Jul  7 21:12:41 1998  Mark Alexander  
194
 
195
        * func.c (bfd_load): Add special handling of a.out executables.
196
 
197
Sat Jun 13 08:33:25 1998  Mark Alexander

200
        * interf.c (run_sim): Print debugging information if verbosity level
201
        is greater than 2.
202
        (sim_open): Repeated -v options now increment verbosity level.
203
        (sim_store_register): Handle little-endian case.
204
        (flush_window): Print debugging information if verbosity level
205
        is greater then 2.
206
 
207
Tue Jun  2 15:20:35 1998  Mark Alexander  
208
 
209
        * interf.c (sim_open): Use revamped memory_read, which makes
210
        byte-swapping unnecessary.  Add -sparclite-board option for
211
        emulating RAM found on typical SPARClite boards.  Print
212
        error message for unrecognized option.
213
        * erc32.c: Change RAM address and size from constants to variables,
214
        to allow emulation of SPARClite board RAM.
215
        (fetch_bytes, store_bytes): New helper functions for revamped
216
        mememory_read and memory_write.
217
        (memory_read, memory_write): Rewrite to store bytes in target
218
        byte order instead of storing words in host byte order; this
219
        greatly simplifies support of little-endian programs.
220
        (get_mem_ptr): Remove unnecessary byte parameter.
221
        (sis_memory_write, sis_memory_read): Store words in target
222
        byte order instead of host byte order.
223
        (byte_swap_words): Remove, no longer needed.
224
        * sis.h ((byte_swap_words): Remove declaration, no longer needed.
225
        (memory_read): Add new sz parameter.
226
        * sis.c (run_sim): Use revamped memory_read, which makes
227
        byte-swapping unnecessary.
228
        * exec.c (dispatch_instruction): Use revamped memory_read, which
229
        makes byte-swapping and double-word fetching unnecessary.
230
        * func.c (sparclite_board): Declare new variable.
231
        (get_regi): Handle little-endian data.
232
        (bfd_load): Recognize little-endian SPARClite as having
233
        little-endian data.
234

244
        * exec.c (SDIV, SDIVCC, UDIV, UDIVCC): Define new opcodes.
245
        * (mul64): Simplify calculation of negative result.
246
        * (div64): New helper function for 64-bit division.
247
        * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
248
        and UDIVCC.
249

251
 
252

253
        (byte_swap_words): New function.
254
        * sis.h: (byte_swap_words): Declare.
255

597
--------------------
598
 
599
* Fixed bug in "go" command.
600
 
601
version 2.0 05-02-96
602
--------------------
603
 
604
* Fixed bug in interrupt force register (erc32.c).
605
 
606
* Change file load function to use bfd_openr.
607
 
608
* SIS should now be endian independent.
609
 
610
version 1.8 24-11-95
611
--------------------
612
 
613
* Fixed FPU timing - some sequences of FPU instructions did not calculate
614
  the resource dependencies right.
615
 
616
* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
617
  but no FPU trap is generated.
618
 
619
version 1.7.1 31-10-95
620
--------------------
621
 
622
* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
623
  the FPU stays in execute mode.
624
 
625
* Corrected JMPL and RETT timing (these instructions takes two cycles).
626
 
627
 
628
version 1.7 25-10-95
629
--------------------
630
 
631

642
 
643
* Fixed bug in STDFQ which caused bus error
644
 
645
 
646
version 1.6 02-10-95
647
--------------------
648
 
649
* Modified srt0.s to include code that initiates registers in IU and FPU
650
  and initializes the data segment. The simulator 'load' command does not
651
  longer initialize the data segment!
652
 
653
* Corrected MEC timer operation; scalers now divide the frequency by
654
  (scaler_value + 1).
655
 
656
* MEC breakpoints are not checked during store operation
657
 
658
 
659
version 1.5 14-09-95
660
--------------------
661
 
662
* Fixed some bugs in the cycle counting for IU & FPU instructions.
663
 
664
* Fixed bug that allowed an annuled instruction to cause memory exception.
665
 
666
* The *ws parameter in mem.c should now contain the number of waitstates
667
  required by the memory access (was total number of cycles).
668
 
669
* The supplied srt0.s now clears the BSS (thanks Joel).
670
 
671
version 1.4 22-08-95
672
--------------------
673
 
674
* Added a '-g' switch to enable/disable the GNU readline(), which cause
675
some problems on solaris 2.x machines.
676
 
677
* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
678
may suffer a bit ...
679
 
680
NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
681
 
682
version 1.3 26-07-95
683
--------------------
684
 
685
* Fixed bug in mulscc instruction (how could that ever have worked?)
686
 
687
* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
688
 
689
version 1.2 13-07-95
690
--------------------
691
 
692
* Fixed bug in interrupt handling (wrong interrupt selected when more that
693
one interrupt pending)
694
 
695
* Fixed updating of condition codes during logical instructions (carry and
696
overflow were not reset)
697
 
698
* Fixed bug in WRTBR (tt field was wrongly over-written)
699
 
700
version 1.1 07-07-95
701
--------------------
702
 
703
* Fixed several bugs in the interrupt handler and callback routines.
