SS		 1481999-02-11 Hugo Tyson <[email protected]>
149
150 * exec.c (dispatch_instruction):
151 Correct the sense of the
152 if (!sparclite) {
153 sregs->trap = TRAP_UNIMP;
154 break;
155 }
156 clause that has been pasted around: it's correct in the SCAN and
157 DIVScc (divide step) cases (where it was probably originally
158 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
159 ie. instructions only in the SPARC V8 or SPARClite 86x
160 architectures. It was also present when not required for SMUL,
161 SMULcc, UMUL, UMULcc instructions that are present in all
162 architectures.
163
1641999-01-25 Hugo Tyson <[email protected]>
165
166 * interf.c (run_sim): Fix a bug in the main loop's handling of
167 annulled delay slot instructions. There is precedent for this
168 change; the _other_ main loop in sis.c gets it right according to
169 my reading of the code.
170
171 The bug is: if an interrupt happens when the next instruction
172 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
173 with the current values of PC and NPC, so when the trap returns,
174 the annulled instruction is indeed executed. Another giveaway is
175 that the annul flag is cleared in execute_trap(): the information
176 is demonstrably discarded.
177
178 The solution is: perform annulling before looking for traps, in
179 fact it's neater to do annulling, see if there's an interrupt and
180 if not, do the instruction, then handle traps be they generated by
181 interrupts pending or by the instruction we might just have done.
182 That's what the sis.c one does.
183
1841999-01-20 Hugo Tyson <[email protected]>
185
186 * sis.h: Add asr17 register for support of SparcLITE (at least the
187 Hitachi ones I find before me)
188
189 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
190 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
191 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
192 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
193 (init_regs): Initialize y and asr17.
194 NB: In instruction-set space, the Y register is asr0; the
195 instructions have different names for human reasons only.
196
197 * sis.c:
198 * interf.c: Set boolean mode variable dumbio if invoked with
199 argument "-dumbio" and mention it of verbose.
200 * erc32.c: if "dumbio" is set, do not assume that there is a
201 terminal type device attached to stdin/stdout. Do not set
202 buffering or mess with tcsetattr or do any read operations in
203 order to make UART interrupts; not input data is supported.
204 This is necessary to allow the sim to be used within the eCos
205 testing infrastructure where stdin/stdout are pipes to a TCL
206 program; the sim hangs otherwise.
207
208Thu Jul 23 07:17:03 1998 Mark Alexander <[email protected]>
209
210 * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
211
212Tue Jul 7 21:12:41 1998 Mark Alexander <[email protected]>
213
214 * func.c (bfd_load): Add special handling of a.out executables.

216Sat Jun 13 08:33:25 1998 Mark Alexander <[email protected]>
217
218 * func.c (bfd_load): Print correct endianness.
219 * interf.c (run_sim): Print debugging information if verbosity level
220 is greater than 2.
221 (sim_open): Repeated -v options now increment verbosity level.
222 (sim_store_register): Handle little-endian case.
223 (flush_window): Print debugging information if verbosity level
224 is greater then 2.
225
226Tue Jun 2 15:20:35 1998 Mark Alexander <[email protected]>
227
228 * interf.c (sim_open): Use revamped memory_read, which makes
229 byte-swapping unnecessary. Add -sparclite-board option for
230 emulating RAM found on typical SPARClite boards. Print
231 error message for unrecognized option.
232 * erc32.c: Change RAM address and size from constants to variables,
233 to allow emulation of SPARClite board RAM.
234 (fetch_bytes, store_bytes): New helper functions for revamped
235 mememory_read and memory_write.
236 (memory_read, memory_write): Rewrite to store bytes in target
237 byte order instead of storing words in host byte order; this
238 greatly simplifies support of little-endian programs.
239 (get_mem_ptr): Remove unnecessary byte parameter.
240 (sis_memory_write, sis_memory_read): Store words in target
241 byte order instead of host byte order.
242 (byte_swap_words): Remove, no longer needed.
243 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
244 (memory_read): Add new sz parameter.
245 * sis.c (run_sim): Use revamped memory_read, which makes
246 byte-swapping unnecessary.
247 * exec.c (dispatch_instruction): Use revamped memory_read, which
248 makes byte-swapping and double-word fetching unnecessary.
249 * func.c (sparclite_board): Declare new variable.
250 (get_regi): Handle little-endian data.
251 (bfd_load): Recognize little-endian SPARClite as having
252 little-endian data.
253

264 * (mul64): Simplify calculation of negative result.
265 * (div64): New helper function for 64-bit division.
266 * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
267 and UDIVCC.
268
269Wed May 13 14:59:54 1998 Mark Alexander <[email protected]>
270
271 * erc32.c (close_port): Don't close stdin; it kills GDB.
272 (byte_swap_words): New function.
273 * sis.h: (byte_swap_words): Declare.
274 * interf.c (run_sim): Always fetch instructions as big-endian.
275 * sis.c (run_sim): Ditto.

560
561 * erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't

586
587 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,

613 byte.
614
615Version 2.1 26-02-96
616--------------------
617
618* Fixed bug in "go" command.
619
620version 2.0 05-02-96
621--------------------
622
623* Fixed bug in interrupt force register (erc32.c).
624
625* Change file load function to use bfd_openr.
626
627* SIS should now be endian independent.
628
629version 1.8 24-11-95
630--------------------
631
632* Fixed FPU timing - some sequences of FPU instructions did not calculate
633 the resource dependencies right.
634
635* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
636 but no FPU trap is generated.
637
638version 1.7.1 31-10-95
639--------------------
640
641* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
642 the FPU stays in execute mode.
643
644* Corrected JMPL and RETT timing (these instructions takes two cycles).
645
646
647version 1.7 25-10-95
648--------------------
649
650* Interrupt during annuled instruction corrupted return address - fixed.
651
652
653version 1.6.2 25-10-95
654--------------------
655
656* Added -DFAST_UART to Makefile
657
658
659version 1.6.1 24-10-95
660--------------------
661
662* Fixed bug in STDFQ which caused bus error
663
664
665version 1.6 02-10-95
666--------------------
667
668* Modified srt0.s to include code that initiates registers in IU and FPU
669 and initializes the data segment. The simulator 'load' command does not
670 longer initialize the data segment!
671
672* Corrected MEC timer operation; scalers now divide the frequency by
673 (scaler_value + 1).
674
675* MEC breakpoints are not checked during store operation
676
677
678version 1.5 14-09-95
679--------------------
680
681* Fixed some bugs in the cycle counting for IU & FPU instructions.
682
683* Fixed bug that allowed an annuled instruction to cause memory exception.
684
685* The *ws parameter in mem.c should now contain the number of waitstates
686 required by the memory access (was total number of cycles).
687
688* The supplied srt0.s now clears the BSS (thanks Joel).
689
690version 1.4 22-08-95
691--------------------
692
693* Added a '-g' switch to enable/disable the GNU readline(), which cause
694some problems on solaris 2.x machines.
695
696* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
697may suffer a bit ...
698
699NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
700
701version 1.3 26-07-95
702--------------------
703
704* Fixed bug in mulscc instruction (how could that ever have worked?)
705
706* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
707
708version 1.2 13-07-95
709--------------------
710
711* Fixed bug in interrupt handling (wrong interrupt selected when more that
712one interrupt pending)
713
714* Fixed updating of condition codes during logical instructions (carry and
715overflow were not reset)
716
717* Fixed bug in WRTBR (tt field was wrongly over-written)
718
719version 1.1 07-07-95
720--------------------
721
722* Fixed several bugs in the interrupt handler and callback routines.
723(reported by Paul Warren, Alsys)
