SS		 3141999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
315
316 * exec.c (dispatch_instruction):
317 Correct the sense of the
318 if (!sparclite) {
319 sregs->trap = TRAP_UNIMP;
320 break;
321 }
322 clause that has been pasted around: it's correct in the SCAN and
323 DIVScc (divide step) cases (where it was probably originally
324 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
325 ie. instructions only in the SPARC V8 or SPARClite 86x
326 architectures. It was also present when not required for SMUL,
327 SMULcc, UMUL, UMULcc instructions that are present in all
328 architectures.
329
3301999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
331
332 * interf.c (run_sim): Fix a bug in the main loop's handling of
333 annulled delay slot instructions. There is precedent for this
334 change; the _other_ main loop in sis.c gets it right according to
335 my reading of the code.
336
337 The bug is: if an interrupt happens when the next instruction
338 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
339 with the current values of PC and NPC, so when the trap returns,
340 the annulled instruction is indeed executed. Another giveaway is
341 that the annul flag is cleared in execute_trap(): the information
342 is demonstrably discarded.
343
344 The solution is: perform annulling before looking for traps, in
345 fact it's neater to do annulling, see if there's an interrupt and
346 if not, do the instruction, then handle traps be they generated by
347 interrupts pending or by the instruction we might just have done.
348 That's what the sis.c one does.
349
3501999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
351
352 * sis.h: Add asr17 register for support of SparcLITE (at least the
353 Hitachi ones I find before me)
354
355 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
356 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
357 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
358 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
359 (init_regs): Initialize y and asr17.
360 NB: In instruction-set space, the Y register is asr0; the
361 instructions have different names for human reasons only.
362
363 * sis.c:
364 * interf.c: Set boolean mode variable dumbio if invoked with
365 argument "-dumbio" and mention it of verbose.
366 * erc32.c: if "dumbio" is set, do not assume that there is a
367 terminal type device attached to stdin/stdout. Do not set
368 buffering or mess with tcsetattr or do any read operations in
369 order to make UART interrupts; not input data is supported.
370 This is necessary to allow the sim to be used within the eCos
371 testing infrastructure where stdin/stdout are pipes to a TCL
372 program; the sim hangs otherwise.

398 * erc32.c: Change RAM address and size from constants to variables,
399 to allow emulation of SPARClite board RAM.
400 (fetch_bytes, store_bytes): New helper functions for revamped
401 mememory_read and memory_write.
402 (memory_read, memory_write): Rewrite to store bytes in target
403 byte order instead of storing words in host byte order; this
404 greatly simplifies support of little-endian programs.
405 (get_mem_ptr): Remove unnecessary byte parameter.
406 (sis_memory_write, sis_memory_read): Store words in target

781Version 2.1 26-02-96
782--------------------
783
784* Fixed bug in "go" command.
785
786version 2.0 05-02-96
787--------------------
788
789* Fixed bug in interrupt force register (erc32.c).
790
791* Change file load function to use bfd_openr.
792
793* SIS should now be endian independent.
794
795version 1.8 24-11-95
796--------------------
797
798* Fixed FPU timing - some sequences of FPU instructions did not calculate
799 the resource dependencies right.
800
801* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
802 but no FPU trap is generated.
803
804version 1.7.1 31-10-95
805--------------------
806
807* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
808 the FPU stays in execute mode.
809
810* Corrected JMPL and RETT timing (these instructions takes two cycles).
811
812
813version 1.7 25-10-95
814--------------------
815
816* Interrupt during annuled instruction corrupted return address - fixed.
817
818
819version 1.6.2 25-10-95
820--------------------
821
822* Added -DFAST_UART to Makefile
823
824
825version 1.6.1 24-10-95
826--------------------
827
828* Fixed bug in STDFQ which caused bus error
829
830
831version 1.6 02-10-95
832--------------------
833
834* Modified srt0.s to include code that initiates registers in IU and FPU
835 and initializes the data segment. The simulator 'load' command does not
836 longer initialize the data segment!
837
838* Corrected MEC timer operation; scalers now divide the frequency by
839 (scaler_value + 1).
840
841* MEC breakpoints are not checked during store operation
842
843
844version 1.5 14-09-95
845--------------------
846
847* Fixed some bugs in the cycle counting for IU & FPU instructions.
848
849* Fixed bug that allowed an annuled instruction to cause memory exception.
850
851* The *ws parameter in mem.c should now contain the number of waitstates
852 required by the memory access (was total number of cycles).
853
854* The supplied srt0.s now clears the BSS (thanks Joel).
855
856version 1.4 22-08-95
857--------------------
858
859* Added a '-g' switch to enable/disable the GNU readline(), which cause
860some problems on solaris 2.x machines.
861
862* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
863may suffer a bit ...
864
865NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
866
867version 1.3 26-07-95
868--------------------
869
870* Fixed bug in mulscc instruction (how could that ever have worked?)
871
872* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
873
874version 1.2 13-07-95
875--------------------
876
877* Fixed bug in interrupt handling (wrong interrupt selected when more that
878one interrupt pending)
879
880* Fixed updating of condition codes during logical instructions (carry and
881overflow were not reset)
882
883* Fixed bug in WRTBR (tt field was wrongly over-written)
884
885version 1.1 07-07-95
886--------------------
887
888* Fixed several bugs in the interrupt handler and callback routines.
