3 | * exec.c (dispatch_instruction): | |
4 | Correct the sense of the | |
5 | if (!sparclite) { | |
6 | sregs->trap = TRAP_UNIMP; | |
7 | break; | |
8 | } | |
9 | clause that has been pasted around: it's correct in the SCAN and | |
10 | DIVScc (divide step) cases (where it was probably originally | |
11 | written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases | |
12 | ie. instructions only in the SPARC V8 or SPARClite 86x | |
13 | architectures. It was also present when not required for SMUL, | |
14 | SMULcc, UMUL, UMULcc instructions that are present in all | |
15 | architectures. | |

18 | ||
19 | * interf.c (run_sim): Fix a bug in the main loop's handling of | |
20 | annulled delay slot instructions. There is precedent for this | |
21 | change; the _other_ main loop in sis.c gets it right according to | |
22 | my reading of the code. | |
23 | ||
24 | The bug is: if an interrupt happens when the next instruction | |
25 | (at sregs->pc) is annulled, the trap is taken (by execute_trap()) | |
26 | with the current values of PC and NPC, so when the trap returns, | |
27 | the annulled instruction is indeed executed. Another giveaway is | |
28 | that the annul flag is cleared in execute_trap(): the information | |
29 | is demonstrably discarded. | |
30 | ||
31 | The solution is: perform annulling before looking for traps, in | |
32 | fact it's neater to do annulling, see if there's an interrupt and | |
33 | if not, do the instruction, then handle traps be they generated by | |
34 | interrupts pending or by the instruction we might just have done. | |
35 | That's what the sis.c one does. | |
36 | ||
37 | 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk> | |
38 | ||
39 | * sis.h: Add asr17 register for support of SparcLITE (at least the | |
40 | Hitachi ones I find before me) | |
41 | ||
42 | * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if | |
43 | sparclite. Other ASR numbers than 17 or 0 (Y) trap out. | |
44 | Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto. | |
45 | (execute_trap): Do single-vector-trapping if asr17 bit 0 is set. | |
46 | (init_regs): Initialize y and asr17. | |
47 | NB: In instruction-set space, the Y register is asr0; the | |
48 | instructions have different names for human reasons only. | |
49 | ||
50 | * sis.c: | |
51 | * interf.c: Set boolean mode variable dumbio if invoked with | |
52 | argument "-dumbio" and mention it of verbose. | |
53 | * erc32.c: if "dumbio" is set, do not assume that there is a | |
54 | terminal type device attached to stdin/stdout. Do not set | |
55 | buffering or mess with tcsetattr or do any read operations in | |
56 | order to make UART interrupts; not input data is supported. | |
57 | This is necessary to allow the sim to be used within the eCos | |
58 | testing infrastructure where stdin/stdout are pipes to a TCL | |
59 | program; the sim hangs otherwise. | |

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

88 | mememory_read and memory_write. | |
89 | (memory_read, memory_write): Rewrite to store bytes in target | |

401 | (AR, AR_FLAGS, BISON, MAKEINFO): Remove duplicate variables. | |
402 | (RANLIB, CC): Likewise. | |
403 | (end): Use $(CC_FOR_BUILD), not $(CC). | |

408 | ||
409 | * erc32.c (port_init): Disable this for __GO32__ (got no pty's | |
410 | there either...). | |
411 | ||
412 | Mon Aug 12 17:04:58 1996 Stu Grossman (grossman@critters.cygnus.com) | |
413 | ||
414 | * erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't | |
415 | necessary. | |
416 | * (port_init): Don't even *try* to open pty's under _WIN32. | |
417 | * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses. | |
418 | * float.c: Get rid of #warning. Makes Microsoft C barf. | |
419 | * interf.c (sim_open): Cast fprintf to (fprintf_ftype) to fix | |
420 | compiler warning. | |
421 | * (sim_load sim_create_inferior sim_read): Use prototypes only in | |
422 | decls, not defs. | |

434 | * interf.c (flush_windows): New routine to flush the register | |
435 | windows out to the stack just before returning to GDB. Makes | |
436 | backtraces work much better. | |
437 | ||
438 | Wed Jun 26 12:19:11 1996 Jason Molenda (crash@godzilla.cygnus.co.jp) | |

452 | Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com> | |
453 | ||
454 | * Makefile.in (install): Don't check to see if tooldir exists. | |
455 | Make $(tooldir) and $(tooldir)/bin. | |
456 | ||
457 | Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com> | |
458 | ||
459 | * Makefile.in (end.h): Use explicit ./ when running end. | |
460 | ||
461 | Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com> | |
462 | ||
463 | * func.c(bfd_load): Don't try to print the filename if the pfbd is | |
464 | NULL. | |
465 | * interf.c(sim_load): Pass the whole string, not just the first | |
466 | byte. | |
467 | ||
468 | Version 2.1 26-02-96 | |
469 | -------------------- | |
470 | ||
471 | * Fixed bug in "go" command. | |
472 | ||
473 | version 2.0 05-02-96 | |
474 | -------------------- | |
475 | ||
476 | * Fixed bug in interrupt force register (erc32.c). | |
477 | ||
478 | * Change file load function to use bfd_openr. | |
479 | ||
480 | * SIS should now be endian independent. | |
481 | ||
482 | version 1.8 24-11-95 | |
483 | -------------------- | |
484 | ||
485 | * Fixed FPU timing - some sequences of FPU instructions did not calculate | |
486 | the resource dependencies right. | |
487 | ||
488 | * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error | |
489 | but no FPU trap is generated. | |
490 | ||
491 | version 1.7.1 31-10-95 | |
492 | -------------------- | |
493 | ||
494 | * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but | |
495 | the FPU stays in execute mode. | |
496 | ||
497 | * Corrected JMPL and RETT timing (these instructions takes two cycles). | |
498 | ||
499 | ||
500 | version 1.7 25-10-95 | |
501 | -------------------- | |
502 | ||
503 | * Interrupt during annuled instruction corrupted return address - fixed. | |
504 | ||
505 | ||
506 | version 1.6.2 25-10-95 | |
507 | -------------------- | |
508 | ||
509 | * Added -DFAST_UART to Makefile | |
510 | ||
511 | ||
512 | version 1.6.1 24-10-95 | |
513 | -------------------- | |
514 | ||
515 | * Fixed bug in STDFQ which caused bus error | |
516 | ||
517 | ||
518 | version 1.6 02-10-95 | |
519 | -------------------- | |
520 | ||
521 | * Modified srt0.s to include code that initiates registers in IU and FPU | |
522 | and initializes the data segment. The simulator 'load' command does not | |
523 | longer initialize the data segment! | |
524 | ||
525 | * Corrected MEC timer operation; scalers now divide the frequency by | |
526 | (scaler_value + 1). | |
527 | ||
528 | * MEC breakpoints are not checked during store operation | |
529 | ||
530 | ||
531 | version 1.5 14-09-95 | |
532 | -------------------- | |
533 | ||
534 | * Fixed some bugs in the cycle counting for IU & FPU instructions. | |
535 | ||
536 | * Fixed bug that allowed an annuled instruction to cause memory exception. | |
537 | ||
538 | * The *ws parameter in mem.c should now contain the number of waitstates | |
539 | required by the memory access (was total number of cycles). | |
540 | ||
541 | * The supplied srt0.s now clears the BSS (thanks Joel). | |
542 | ||
543 | version 1.4 22-08-95 | |
544 | -------------------- | |
545 | ||
546 | * Added a '-g' switch to enable/disable the GNU readline(), which cause | |
547 | some problems on solaris 2.x machines. | |
548 | ||
549 | * Enabled MEC watchpoint and breakpoint function to mem.c. Performance | |
550 | may suffer a bit ... | |
551 | ||
552 | NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd. | |
553 | ||
554 | version 1.3 26-07-95 | |
555 | -------------------- | |
556 | ||
557 | * Fixed bug in mulscc instruction (how could that ever have worked?) | |
558 | ||
559 | * Fixed bug in UART B (flushed characters on UART A), thanks Paul. | |
560 | ||
561 | version 1.2 13-07-95 | |
562 | -------------------- | |
563 | ||
564 | * Fixed bug in interrupt handling (wrong interrupt selected when more that | |
565 | one interrupt pending) | |
566 | ||
567 | * Fixed updating of condition codes during logical instructions (carry and | |
568 | overflow were not reset) | |
569 | ||
570 | * Fixed bug in WRTBR (tt field was wrongly over-written) | |
571 | ||
572 | version 1.1 07-07-95 | |
573 | -------------------- | |
574 | ||
575 | * Fixed several bugs in the interrupt handler and callback routines. | |
