299 * exec.c (dispatch_instruction):
300 Correct the sense of the
301 if (!sparclite) {
302 sregs->trap = TRAP_UNIMP;
303 break;
304 }
305 clause that has been pasted around: it's correct in the SCAN and
306 DIVScc (divide step) cases (where it was probably originally
307 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
308 ie. instructions only in the SPARC V8 or SPARClite 86x
309 architectures. It was also present when not required for SMUL,
310 SMULcc, UMUL, UMULcc instructions that are present in all
311 architectures.
312
3131999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
314
315 * interf.c (run_sim): Fix a bug in the main loop's handling of
316 annulled delay slot instructions. There is precedent for this
317 change; the _other_ main loop in sis.c gets it right according to
318 my reading of the code.
319
320 The bug is: if an interrupt happens when the next instruction
321 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
322 with the current values of PC and NPC, so when the trap returns,
323 the annulled instruction is indeed executed. Another giveaway is
324 that the annul flag is cleared in execute_trap(): the information
325 is demonstrably discarded.
326
327 The solution is: perform annulling before looking for traps, in
328 fact it's neater to do annulling, see if there's an interrupt and
329 if not, do the instruction, then handle traps be they generated by
330 interrupts pending or by the instruction we might just have done.
331 That's what the sis.c one does.
332
3331999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
334
335 * sis.h: Add asr17 register for support of SparcLITE (at least the
336 Hitachi ones I find before me)
337
338 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
339 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
340 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
341 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
342 (init_regs): Initialize y and asr17.
343 NB: In instruction-set space, the Y register is asr0; the
344 instructions have different names for human reasons only.
345
346 * sis.c:
347 * interf.c: Set boolean mode variable dumbio if invoked with
348 argument "-dumbio" and mention it of verbose.
349 * erc32.c: if "dumbio" is set, do not assume that there is a
350 terminal type device attached to stdin/stdout. Do not set
351 buffering or mess with tcsetattr or do any read operations in
352 order to make UART interrupts; not input data is supported.
353 This is necessary to allow the sim to be used within the eCos
354 testing infrastructure where stdin/stdout are pipes to a TCL
355 program; the sim hangs otherwise.

383 (fetch_bytes, store_bytes): New helper functions for revamped

764Version 2.1 26-02-96
765--------------------
766
767* Fixed bug in "go" command.
768
769version 2.0 05-02-96
770--------------------
771
772* Fixed bug in interrupt force register (erc32.c).
773
774* Change file load function to use bfd_openr.
775
776* SIS should now be endian independent.
777
778version 1.8 24-11-95
779--------------------
780
781* Fixed FPU timing - some sequences of FPU instructions did not calculate
782 the resource dependencies right.
783
784* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
785 but no FPU trap is generated.
786
787version 1.7.1 31-10-95
788--------------------
789
790* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
791 the FPU stays in execute mode.
792
793* Corrected JMPL and RETT timing (these instructions takes two cycles).
794
795
796version 1.7 25-10-95
797--------------------
798
799* Interrupt during annuled instruction corrupted return address - fixed.
800
801
802version 1.6.2 25-10-95
803--------------------
804
805* Added -DFAST_UART to Makefile
806
807
808version 1.6.1 24-10-95
809--------------------
810
811* Fixed bug in STDFQ which caused bus error
812
813
814version 1.6 02-10-95
815--------------------
816
817* Modified srt0.s to include code that initiates registers in IU and FPU
818 and initializes the data segment. The simulator 'load' command does not
819 longer initialize the data segment!
820
821* Corrected MEC timer operation; scalers now divide the frequency by
822 (scaler_value + 1).
823
824* MEC breakpoints are not checked during store operation
825
826
827version 1.5 14-09-95
828--------------------
829
830* Fixed some bugs in the cycle counting for IU & FPU instructions.
831
832* Fixed bug that allowed an annuled instruction to cause memory exception.
833
834* The *ws parameter in mem.c should now contain the number of waitstates
835 required by the memory access (was total number of cycles).
836
837* The supplied srt0.s now clears the BSS (thanks Joel).
838
839version 1.4 22-08-95
840--------------------
841
842* Added a '-g' switch to enable/disable the GNU readline(), which cause
843some problems on solaris 2.x machines.
844
845* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
846may suffer a bit ...
847
848NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
849
850version 1.3 26-07-95
851--------------------
852
853* Fixed bug in mulscc instruction (how could that ever have worked?)
854
855* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
856
857version 1.2 13-07-95
858--------------------
859
860* Fixed bug in interrupt handling (wrong interrupt selected when more that
861one interrupt pending)
862
863* Fixed updating of condition codes during logical instructions (carry and
864overflow were not reset)
865
866* Fixed bug in WRTBR (tt field was wrongly over-written)
867
868version 1.1 07-07-95
869--------------------
870
871* Fixed several bugs in the interrupt handler and callback routines.
872(reported by Paul Warren, Alsys)
