SS		 2031999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
204
205 * exec.c (dispatch_instruction):
206 Correct the sense of the
207 if (!sparclite) {
208 sregs->trap = TRAP_UNIMP;
209 break;
210 }
211 clause that has been pasted around: it's correct in the SCAN and
212 DIVScc (divide step) cases (where it was probably originally
213 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
214 ie. instructions only in the SPARC V8 or SPARClite 86x
215 architectures. It was also present when not required for SMUL,
216 SMULcc, UMUL, UMULcc instructions that are present in all
217 architectures.
218
2191999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
220
221 * interf.c (run_sim): Fix a bug in the main loop's handling of
222 annulled delay slot instructions. There is precedent for this
223 change; the _other_ main loop in sis.c gets it right according to
224 my reading of the code.
225
226 The bug is: if an interrupt happens when the next instruction
227 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
228 with the current values of PC and NPC, so when the trap returns,
229 the annulled instruction is indeed executed. Another giveaway is
230 that the annul flag is cleared in execute_trap(): the information
231 is demonstrably discarded.
232
233 The solution is: perform annulling before looking for traps, in
234 fact it's neater to do annulling, see if there's an interrupt and
235 if not, do the instruction, then handle traps be they generated by
236 interrupts pending or by the instruction we might just have done.
237 That's what the sis.c one does.
238
2391999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
240
241 * sis.h: Add asr17 register for support of SparcLITE (at least the
242 Hitachi ones I find before me)
243
244 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
245 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
246 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
247 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
248 (init_regs): Initialize y and asr17.
249 NB: In instruction-set space, the Y register is asr0; the
250 instructions have different names for human reasons only.
251
252 * sis.c:
253 * interf.c: Set boolean mode variable dumbio if invoked with
254 argument "-dumbio" and mention it of verbose.
255 * erc32.c: if "dumbio" is set, do not assume that there is a
256 terminal type device attached to stdin/stdout. Do not set
257 buffering or mess with tcsetattr or do any read operations in
258 order to make UART interrupts; not input data is supported.
259 This is necessary to allow the sim to be used within the eCos
260 testing infrastructure where stdin/stdout are pipes to a TCL
261 program; the sim hangs otherwise.
262
263Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>
264
265 * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
266
267Tue Jul 7 21:12:41 1998 Mark Alexander <marka@cygnus.com>
268

272
273 * func.c (bfd_load): Print correct endianness.
274 * interf.c (run_sim): Print debugging information if verbosity level
275 is greater than 2.
276 (sim_open): Repeated -v options now increment verbosity level.
277 (sim_store_register): Handle little-endian case.
278 (flush_window): Print debugging information if verbosity level
279 is greater then 2.
280
281Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
282
283 * interf.c (sim_open): Use revamped memory_read, which makes
284 byte-swapping unnecessary. Add -sparclite-board option for
285 emulating RAM found on typical SPARClite boards. Print
286 error message for unrecognized option.
287 * erc32.c: Change RAM address and size from constants to variables,
288 to allow emulation of SPARClite board RAM.
289 (fetch_bytes, store_bytes): New helper functions for revamped
290 mememory_read and memory_write.
291 (memory_read, memory_write): Rewrite to store bytes in target
292 byte order instead of storing words in host byte order; this
293 greatly simplifies support of little-endian programs.
294 (get_mem_ptr): Remove unnecessary byte parameter.
295 (sis_memory_write, sis_memory_read): Store words in target
296 byte order instead of host byte order.
297 (byte_swap_words): Remove, no longer needed.
298 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
299 (memory_read): Add new sz parameter.
300 * sis.c (run_sim): Use revamped memory_read, which makes
301 byte-swapping unnecessary.
302 * exec.c (dispatch_instruction): Use revamped memory_read, which
303 makes byte-swapping and double-word fetching unnecessary.
304 * func.c (sparclite_board): Declare new variable.
305 (get_regi): Handle little-endian data.
306 (bfd_load): Recognize little-endian SPARClite as having
307 little-endian data.

319 * (mul64): Simplify calculation of negative result.
320 * (div64): New helper function for 64-bit division.
321 * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
322 and UDIVCC.
323
324Wed May 13 14:59:54 1998 Mark Alexander <marka@cygnus.com>
325
326 * erc32.c (close_port): Don't close stdin; it kills GDB.
327 (byte_swap_words): New function.
328 * sis.h: (byte_swap_words): Declare.
329 * interf.c (run_sim): Always fetch instructions as big-endian.
330 * sis.c (run_sim): Ditto.

669
670Version 2.1 26-02-96
671--------------------
672
673* Fixed bug in "go" command.
674
675version 2.0 05-02-96
676--------------------
677
678* Fixed bug in interrupt force register (erc32.c).
679
680* Change file load function to use bfd_openr.
681
682* SIS should now be endian independent.
683
684version 1.8 24-11-95
685--------------------
686
687* Fixed FPU timing - some sequences of FPU instructions did not calculate
688 the resource dependencies right.
689
690* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
691 but no FPU trap is generated.
692
693version 1.7.1 31-10-95
694--------------------
695
696* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
697 the FPU stays in execute mode.
698
699* Corrected JMPL and RETT timing (these instructions takes two cycles).
700
701
702version 1.7 25-10-95
703--------------------
704
705* Interrupt during annuled instruction corrupted return address - fixed.
706
707
708version 1.6.2 25-10-95
709--------------------
710
711* Added -DFAST_UART to Makefile
712
713
714version 1.6.1 24-10-95
715--------------------
716
717* Fixed bug in STDFQ which caused bus error
718
719
720version 1.6 02-10-95
721--------------------
722
723* Modified srt0.s to include code that initiates registers in IU and FPU
724 and initializes the data segment. The simulator 'load' command does not
725 longer initialize the data segment!
726
727* Corrected MEC timer operation; scalers now divide the frequency by
728 (scaler_value + 1).
729
730* MEC breakpoints are not checked during store operation
731
732
733version 1.5 14-09-95
734--------------------
735
736* Fixed some bugs in the cycle counting for IU & FPU instructions.
737
738* Fixed bug that allowed an annuled instruction to cause memory exception.
739
740* The *ws parameter in mem.c should now contain the number of waitstates
741 required by the memory access (was total number of cycles).
742
743* The supplied srt0.s now clears the BSS (thanks Joel).
744
745version 1.4 22-08-95
746--------------------
747
748* Added a '-g' switch to enable/disable the GNU readline(), which cause
749some problems on solaris 2.x machines.
750
751* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
752may suffer a bit ...
753
754NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
755
756version 1.3 26-07-95
757--------------------
758
759* Fixed bug in mulscc instruction (how could that ever have worked?)
760
761* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
762
763version 1.2 13-07-95
764--------------------
765
766* Fixed bug in interrupt handling (wrong interrupt selected when more that
767one interrupt pending)
768
769* Fixed updating of condition codes during logical instructions (carry and
770overflow were not reset)
771
772* Fixed bug in WRTBR (tt field was wrongly over-written)
773
774version 1.1 07-07-95
775--------------------
776
777* Fixed several bugs in the interrupt handler and callback routines.
