26 | * exec.c (dispatch_instruction): | |
27 | Correct the sense of the | |
28 | if (!sparclite) { | |
29 | sregs->trap = TRAP_UNIMP; | |
30 | break; | |
31 | } | |
32 | clause that has been pasted around: it's correct in the SCAN and | |
33 | DIVScc (divide step) cases (where it was probably originally | |
34 | written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases | |
35 | ie. instructions only in the SPARC V8 or SPARClite 86x | |
36 | architectures. It was also present when not required for SMUL, | |
37 | SMULcc, UMUL, UMULcc instructions that are present in all | |
38 | architectures. | |
39 | ||
40 | 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk> | |
41 | ||
42 | * interf.c (run_sim): Fix a bug in the main loop's handling of | |
43 | annulled delay slot instructions. There is precedent for this | |
44 | change; the _other_ main loop in sis.c gets it right according to | |
45 | my reading of the code. | |
46 | ||
47 | The bug is: if an interrupt happens when the next instruction | |
48 | (at sregs->pc) is annulled, the trap is taken (by execute_trap()) | |
49 | with the current values of PC and NPC, so when the trap returns, | |
50 | the annulled instruction is indeed executed. Another giveaway is | |
51 | that the annul flag is cleared in execute_trap(): the information | |
52 | is demonstrably discarded. | |
53 | ||
54 | The solution is: perform annulling before looking for traps, in | |
55 | fact it's neater to do annulling, see if there's an interrupt and | |
56 | if not, do the instruction, then handle traps be they generated by | |
57 | interrupts pending or by the instruction we might just have done. | |
58 | That's what the sis.c one does. | |
59 | ||
60 | 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk> | |
61 | ||
62 | * sis.h: Add asr17 register for support of SparcLITE (at least the | |
63 | Hitachi ones I find before me) | |
64 | ||
65 | * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if | |
66 | sparclite. Other ASR numbers than 17 or 0 (Y) trap out. | |
67 | Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto. | |
68 | (execute_trap): Do single-vector-trapping if asr17 bit 0 is set. | |
69 | (init_regs): Initialize y and asr17. | |
70 | NB: In instruction-set space, the Y register is asr0; the | |
71 | instructions have different names for human reasons only. | |
72 | ||
73 | * sis.c: | |
74 | * interf.c: Set boolean mode variable dumbio if invoked with | |
75 | argument "-dumbio" and mention it of verbose. | |
76 | * erc32.c: if "dumbio" is set, do not assume that there is a | |
77 | terminal type device attached to stdin/stdout. Do not set | |
78 | buffering or mess with tcsetattr or do any read operations in | |
79 | order to make UART interrupts; not input data is supported. | |
80 | This is necessary to allow the sim to be used within the eCos | |
81 | testing infrastructure where stdin/stdout are pipes to a TCL | |
82 | program; the sim hangs otherwise. | |

84 | Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com> | |
85 | ||
86 | * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction. | |

93 | ||
94 | * func.c (bfd_load): Print correct endianness. | |
95 | * interf.c (run_sim): Print debugging information if verbosity level | |
96 | is greater than 2. | |

102 | Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com> | |
103 | ||
104 | * interf.c (sim_open): Use revamped memory_read, which makes | |
105 | byte-swapping unnecessary. Add -sparclite-board option for | |
106 | emulating RAM found on typical SPARClite boards. Print | |
107 | error message for unrecognized option. | |
108 | * erc32.c: Change RAM address and size from constants to variables, | |
109 | to allow emulation of SPARClite board RAM. | |
110 | (fetch_bytes, store_bytes): New helper functions for revamped | |
111 | mememory_read and memory_write. | |
112 | (memory_read, memory_write): Rewrite to store bytes in target | |
113 | byte order instead of storing words in host byte order; this | |

121 | * sis.c (run_sim): Use revamped memory_read, which makes | |
122 | byte-swapping unnecessary. | |
123 | * exec.c (dispatch_instruction): Use revamped memory_read, which | |
124 | makes byte-swapping and double-word fetching unnecessary. | |
125 | * func.c (sparclite_board): Declare new variable. | |
126 | (get_regi): Handle little-endian data. | |
127 | (bfd_load): Recognize little-endian SPARClite as having | |

490 | ||
491 | Version 2.1 26-02-96 | |
492 | -------------------- | |
493 | ||
494 | * Fixed bug in "go" command. | |
495 | ||
496 | version 2.0 05-02-96 | |
497 | -------------------- | |
498 | ||
499 | * Fixed bug in interrupt force register (erc32.c). | |
500 | ||
501 | * Change file load function to use bfd_openr. | |
502 | ||
503 | * SIS should now be endian independent. | |
504 | ||
505 | version 1.8 24-11-95 | |
506 | -------------------- | |
507 | ||
508 | * Fixed FPU timing - some sequences of FPU instructions did not calculate | |
509 | the resource dependencies right. | |
510 | ||
511 | * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error | |
512 | but no FPU trap is generated. | |
513 | ||
514 | version 1.7.1 31-10-95 | |
515 | -------------------- | |
516 | ||
517 | * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but | |
518 | the FPU stays in execute mode. | |
519 | ||
520 | * Corrected JMPL and RETT timing (these instructions takes two cycles). | |
521 | ||
522 | ||
523 | version 1.7 25-10-95 | |
524 | -------------------- | |
525 | ||
526 | * Interrupt during annuled instruction corrupted return address - fixed. | |
527 | ||
528 | ||
529 | version 1.6.2 25-10-95 | |
530 | -------------------- | |
531 | ||
532 | * Added -DFAST_UART to Makefile | |
533 | ||
534 | ||
535 | version 1.6.1 24-10-95 | |
536 | -------------------- | |
537 | ||
538 | * Fixed bug in STDFQ which caused bus error | |
539 | ||
540 | ||
541 | version 1.6 02-10-95 | |
542 | -------------------- | |
543 | ||
544 | * Modified srt0.s to include code that initiates registers in IU and FPU | |
545 | and initializes the data segment. The simulator 'load' command does not | |
546 | longer initialize the data segment! | |
547 | ||
548 | * Corrected MEC timer operation; scalers now divide the frequency by | |
549 | (scaler_value + 1). | |
550 | ||
551 | * MEC breakpoints are not checked during store operation | |
552 | ||
553 | ||
554 | version 1.5 14-09-95 | |
555 | -------------------- | |
556 | ||
557 | * Fixed some bugs in the cycle counting for IU & FPU instructions. | |
558 | ||
559 | * Fixed bug that allowed an annuled instruction to cause memory exception. | |
560 | ||
561 | * The *ws parameter in mem.c should now contain the number of waitstates | |
562 | required by the memory access (was total number of cycles). | |
563 | ||
564 | * The supplied srt0.s now clears the BSS (thanks Joel). | |
565 | ||
566 | version 1.4 22-08-95 | |
567 | -------------------- | |
568 | ||
569 | * Added a '-g' switch to enable/disable the GNU readline(), which cause | |
570 | some problems on solaris 2.x machines. | |
571 | ||
572 | * Enabled MEC watchpoint and breakpoint function to mem.c. Performance | |
573 | may suffer a bit ... | |
574 | ||
575 | NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd. | |
576 | ||
577 | version 1.3 26-07-95 | |
578 | -------------------- | |
579 | ||
580 | * Fixed bug in mulscc instruction (how could that ever have worked?) | |
581 | ||
582 | * Fixed bug in UART B (flushed characters on UART A), thanks Paul. | |
583 | ||
584 | version 1.2 13-07-95 | |
585 | -------------------- | |
586 | ||
587 | * Fixed bug in interrupt handling (wrong interrupt selected when more that | |
588 | one interrupt pending) | |
589 | ||
590 | * Fixed updating of condition codes during logical instructions (carry and | |
591 | overflow were not reset) | |
592 | ||
593 | * Fixed bug in WRTBR (tt field was wrongly over-written) | |
594 | ||
595 | version 1.1 07-07-95 | |
596 | -------------------- | |
597 | ||
598 | * Fixed several bugs in the interrupt handler and callback routines. | |
599 | (reported by Paul Warren, Alsys) |
