SS		 1441999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
145
146 * exec.c (dispatch_instruction):
147 Correct the sense of the
148 if (!sparclite) {
149 sregs->trap = TRAP_UNIMP;
150 break;
151 }
152 clause that has been pasted around: it's correct in the SCAN and
153 DIVScc (divide step) cases (where it was probably originally
154 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
155 ie. instructions only in the SPARC V8 or SPARClite 86x
156 architectures. It was also present when not required for SMUL,
157 SMULcc, UMUL, UMULcc instructions that are present in all
158 architectures.
159
1601999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
161
162 * interf.c (run_sim): Fix a bug in the main loop's handling of
163 annulled delay slot instructions. There is precedent for this
164 change; the _other_ main loop in sis.c gets it right according to
165 my reading of the code.
166
167 The bug is: if an interrupt happens when the next instruction
168 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
169 with the current values of PC and NPC, so when the trap returns,
170 the annulled instruction is indeed executed. Another giveaway is
171 that the annul flag is cleared in execute_trap(): the information
172 is demonstrably discarded.
173
174 The solution is: perform annulling before looking for traps, in
175 fact it's neater to do annulling, see if there's an interrupt and
176 if not, do the instruction, then handle traps be they generated by
177 interrupts pending or by the instruction we might just have done.
178 That's what the sis.c one does.
179
1801999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
181
182 * sis.h: Add asr17 register for support of SparcLITE (at least the
183 Hitachi ones I find before me)
184
185 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
186 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
187 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
188 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
189 (init_regs): Initialize y and asr17.
190 NB: In instruction-set space, the Y register is asr0; the
191 instructions have different names for human reasons only.
192
193 * sis.c:
194 * interf.c: Set boolean mode variable dumbio if invoked with
195 argument "-dumbio" and mention it of verbose.
196 * erc32.c: if "dumbio" is set, do not assume that there is a
197 terminal type device attached to stdin/stdout. Do not set
198 buffering or mess with tcsetattr or do any read operations in
199 order to make UART interrupts; not input data is supported.
200 This is necessary to allow the sim to be used within the eCos
201 testing infrastructure where stdin/stdout are pipes to a TCL
202 program; the sim hangs otherwise.
203
204Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>
205
206 * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.

212Sat Jun 13 08:33:25 1998 Mark Alexander <marka@cygnus.com>
213
214 * func.c (bfd_load): Print correct endianness.
215 * interf.c (run_sim): Print debugging information if verbosity level
216 is greater than 2.
217 (sim_open): Repeated -v options now increment verbosity level.
218 (sim_store_register): Handle little-endian case.
219 (flush_window): Print debugging information if verbosity level
220 is greater then 2.
221
222Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
223
224 * interf.c (sim_open): Use revamped memory_read, which makes
225 byte-swapping unnecessary. Add -sparclite-board option for
226 emulating RAM found on typical SPARClite boards. Print
227 error message for unrecognized option.
228 * erc32.c: Change RAM address and size from constants to variables,
229 to allow emulation of SPARClite board RAM.
230 (fetch_bytes, store_bytes): New helper functions for revamped
231 mememory_read and memory_write.
232 (memory_read, memory_write): Rewrite to store bytes in target
233 byte order instead of storing words in host byte order; this
234 greatly simplifies support of little-endian programs.
235 (get_mem_ptr): Remove unnecessary byte parameter.
236 (sis_memory_write, sis_memory_read): Store words in target
237 byte order instead of host byte order.
238 (byte_swap_words): Remove, no longer needed.
239 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
240 (memory_read): Add new sz parameter.
241 * sis.c (run_sim): Use revamped memory_read, which makes
242 byte-swapping unnecessary.
243 * exec.c (dispatch_instruction): Use revamped memory_read, which
244 makes byte-swapping and double-word fetching unnecessary.
245 * func.c (sparclite_board): Declare new variable.
246 (get_regi): Handle little-endian data.
247 (bfd_load): Recognize little-endian SPARClite as having
248 little-endian data.

261 * (div64): New helper function for 64-bit division.
262 * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
263 and UDIVCC.
264
265Wed May 13 14:59:54 1998 Mark Alexander <marka@cygnus.com>
266
267 * erc32.c (close_port): Don't close stdin; it kills GDB.
268 (byte_swap_words): New function.
269 * sis.h: (byte_swap_words): Declare.
270 * interf.c (run_sim): Always fetch instructions as big-endian.
271 * sis.c (run_sim): Ditto.

610
611Version 2.1 26-02-96
612--------------------
613
614* Fixed bug in "go" command.
615
616version 2.0 05-02-96
617--------------------
618
619* Fixed bug in interrupt force register (erc32.c).
620
621* Change file load function to use bfd_openr.
622
623* SIS should now be endian independent.
624
625version 1.8 24-11-95
626--------------------
627
628* Fixed FPU timing - some sequences of FPU instructions did not calculate
629 the resource dependencies right.
630
631* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
632 but no FPU trap is generated.
633
634version 1.7.1 31-10-95
635--------------------
636
637* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
638 the FPU stays in execute mode.
639
640* Corrected JMPL and RETT timing (these instructions takes two cycles).
641
642
643version 1.7 25-10-95
644--------------------
645
646* Interrupt during annuled instruction corrupted return address - fixed.
647
648
649version 1.6.2 25-10-95
650--------------------
651
652* Added -DFAST_UART to Makefile
653
654
655version 1.6.1 24-10-95
656--------------------
657
658* Fixed bug in STDFQ which caused bus error
659
660
661version 1.6 02-10-95
662--------------------
663
664* Modified srt0.s to include code that initiates registers in IU and FPU
665 and initializes the data segment. The simulator 'load' command does not
666 longer initialize the data segment!
667
668* Corrected MEC timer operation; scalers now divide the frequency by
669 (scaler_value + 1).
670
671* MEC breakpoints are not checked during store operation
672
673
674version 1.5 14-09-95
675--------------------
676
677* Fixed some bugs in the cycle counting for IU & FPU instructions.
678
679* Fixed bug that allowed an annuled instruction to cause memory exception.
680
681* The *ws parameter in mem.c should now contain the number of waitstates
682 required by the memory access (was total number of cycles).
683
684* The supplied srt0.s now clears the BSS (thanks Joel).
685
686version 1.4 22-08-95
687--------------------
688
689* Added a '-g' switch to enable/disable the GNU readline(), which cause
690some problems on solaris 2.x machines.
691
692* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
693may suffer a bit ...
694
695NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
696
697version 1.3 26-07-95
698--------------------
699
700* Fixed bug in mulscc instruction (how could that ever have worked?)
701
702* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
703
704version 1.2 13-07-95
705--------------------
706
707* Fixed bug in interrupt handling (wrong interrupt selected when more that
708one interrupt pending)
709
710* Fixed updating of condition codes during logical instructions (carry and
711overflow were not reset)
712
713* Fixed bug in WRTBR (tt field was wrongly over-written)
714
715version 1.1 07-07-95
716--------------------
717
718* Fixed several bugs in the interrupt handler and callback routines.
