43 | * exec.c (dispatch_instruction): | |
44 | Correct the sense of the | |
45 | if (!sparclite) { | |
46 | sregs->trap = TRAP_UNIMP; | |
47 | break; | |
48 | } | |
49 | clause that has been pasted around: it's correct in the SCAN and | |
50 | DIVScc (divide step) cases (where it was probably originally | |
51 | written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases | |
52 | ie. instructions only in the SPARC V8 or SPARClite 86x | |
53 | architectures. It was also present when not required for SMUL, | |
54 | SMULcc, UMUL, UMULcc instructions that are present in all | |
55 | architectures. | |
56 | ||
57 | 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk> | |
58 | ||
59 | * interf.c (run_sim): Fix a bug in the main loop's handling of | |
60 | annulled delay slot instructions. There is precedent for this | |
61 | change; the _other_ main loop in sis.c gets it right according to | |
62 | my reading of the code. | |
63 | ||
64 | The bug is: if an interrupt happens when the next instruction | |
65 | (at sregs->pc) is annulled, the trap is taken (by execute_trap()) | |
66 | with the current values of PC and NPC, so when the trap returns, | |
67 | the annulled instruction is indeed executed. Another giveaway is | |
68 | that the annul flag is cleared in execute_trap(): the information | |
69 | is demonstrably discarded. | |
70 | ||
71 | The solution is: perform annulling before looking for traps, in | |
72 | fact it's neater to do annulling, see if there's an interrupt and | |
73 | if not, do the instruction, then handle traps be they generated by | |
74 | interrupts pending or by the instruction we might just have done. | |
75 | That's what the sis.c one does. | |
76 | ||
77 | 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk> | |
78 | ||
79 | * sis.h: Add asr17 register for support of SparcLITE (at least the | |
80 | Hitachi ones I find before me) | |
81 | ||
82 | * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if | |
83 | sparclite. Other ASR numbers than 17 or 0 (Y) trap out. | |
84 | Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto. | |
85 | (execute_trap): Do single-vector-trapping if asr17 bit 0 is set. | |
86 | (init_regs): Initialize y and asr17. | |
87 | NB: In instruction-set space, the Y register is asr0; the | |
88 | instructions have different names for human reasons only. | |
89 | ||
90 | * sis.c: | |
91 | * interf.c: Set boolean mode variable dumbio if invoked with | |
92 | argument "-dumbio" and mention it of verbose. | |
93 | * erc32.c: if "dumbio" is set, do not assume that there is a | |
94 | terminal type device attached to stdin/stdout. Do not set | |
95 | buffering or mess with tcsetattr or do any read operations in | |
96 | order to make UART interrupts; not input data is supported. | |
97 | This is necessary to allow the sim to be used within the eCos | |
98 | testing infrastructure where stdin/stdout are pipes to a TCL | |
99 | program; the sim hangs otherwise. | |

101 | Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com> | |

121 | * interf.c (sim_open): Use revamped memory_read, which makes | |
122 | byte-swapping unnecessary. Add -sparclite-board option for | |
123 | emulating RAM found on typical SPARClite boards. Print | |
124 | error message for unrecognized option. | |

128 | mememory_read and memory_write. | |

453 | ||
454 | * erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't | |

507 | ||
508 | Version 2.1 26-02-96 | |
509 | -------------------- | |
510 | ||
511 | * Fixed bug in "go" command. | |
512 | ||
513 | version 2.0 05-02-96 | |
514 | -------------------- | |
515 | ||
516 | * Fixed bug in interrupt force register (erc32.c). | |
517 | ||
518 | * Change file load function to use bfd_openr. | |
519 | ||
520 | * SIS should now be endian independent. | |
521 | ||
522 | version 1.8 24-11-95 | |
523 | -------------------- | |
524 | ||
525 | * Fixed FPU timing - some sequences of FPU instructions did not calculate | |
526 | the resource dependencies right. | |
527 | ||
528 | * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error | |
529 | but no FPU trap is generated. | |
530 | ||
531 | version 1.7.1 31-10-95 | |
532 | -------------------- | |
533 | ||
534 | * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but | |
535 | the FPU stays in execute mode. | |
536 | ||
537 | * Corrected JMPL and RETT timing (these instructions takes two cycles). | |
538 | ||
539 | ||
540 | version 1.7 25-10-95 | |
541 | -------------------- | |
542 | ||
543 | * Interrupt during annuled instruction corrupted return address - fixed. | |
544 | ||
545 | ||
546 | version 1.6.2 25-10-95 | |
547 | -------------------- | |
548 | ||
549 | * Added -DFAST_UART to Makefile | |
550 | ||
551 | ||
552 | version 1.6.1 24-10-95 | |
553 | -------------------- | |
554 | ||
555 | * Fixed bug in STDFQ which caused bus error | |
556 | ||
557 | ||
558 | version 1.6 02-10-95 | |
559 | -------------------- | |
560 | ||
561 | * Modified srt0.s to include code that initiates registers in IU and FPU | |
562 | and initializes the data segment. The simulator 'load' command does not | |
563 | longer initialize the data segment! | |
564 | ||
565 | * Corrected MEC timer operation; scalers now divide the frequency by | |
566 | (scaler_value + 1). | |
567 | ||
568 | * MEC breakpoints are not checked during store operation | |
569 | ||
570 | ||
571 | version 1.5 14-09-95 | |
572 | -------------------- | |
573 | ||
574 | * Fixed some bugs in the cycle counting for IU & FPU instructions. | |
575 | ||
576 | * Fixed bug that allowed an annuled instruction to cause memory exception. | |
577 | ||
578 | * The *ws parameter in mem.c should now contain the number of waitstates | |
579 | required by the memory access (was total number of cycles). | |
580 | ||
581 | * The supplied srt0.s now clears the BSS (thanks Joel). | |
582 | ||
583 | version 1.4 22-08-95 | |
584 | -------------------- | |
585 | ||
586 | * Added a '-g' switch to enable/disable the GNU readline(), which cause | |
587 | some problems on solaris 2.x machines. | |
588 | ||
589 | * Enabled MEC watchpoint and breakpoint function to mem.c. Performance | |
590 | may suffer a bit ... | |
591 | ||
592 | NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd. | |
593 | ||
594 | version 1.3 26-07-95 | |
595 | -------------------- | |
596 | ||
597 | * Fixed bug in mulscc instruction (how could that ever have worked?) | |
598 | ||
599 | * Fixed bug in UART B (flushed characters on UART A), thanks Paul. | |
600 | ||
601 | version 1.2 13-07-95 | |
602 | -------------------- | |
603 | ||
604 | * Fixed bug in interrupt handling (wrong interrupt selected when more that | |
605 | one interrupt pending) | |
606 | ||
607 | * Fixed updating of condition codes during logical instructions (carry and | |
608 | overflow were not reset) | |
609 | ||
610 | * Fixed bug in WRTBR (tt field was wrongly over-written) | |
611 | ||
612 | version 1.1 07-07-95 | |
613 | -------------------- | |
614 | ||
615 | * Fixed several bugs in the interrupt handler and callback routines. | |
616 | (reported by Paul Warren, Alsys) |
