467 | ||
72f4393d | 468 | * exec.c (dispatch_instruction): |
c906108c SS |
469 | Correct the sense of the |
470 | if (!sparclite) { | |
471 | sregs->trap = TRAP_UNIMP; | |
72f4393d | 472 | break; |
c906108c SS |
473 | } |
474 | clause that has been pasted around: it's correct in the SCAN and | |
475 | DIVScc (divide step) cases (where it was probably originally | |
476 | written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases | |
477 | ie. instructions only in the SPARC V8 or SPARClite 86x | |
478 | architectures. It was also present when not required for SMUL, | |
479 | SMULcc, UMUL, UMULcc instructions that are present in all | |
480 | architectures. | |
481 | ||
482 | 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk> | |
483 | ||
484 | * interf.c (run_sim): Fix a bug in the main loop's handling of | |
485 | annulled delay slot instructions. There is precedent for this | |
486 | change; the _other_ main loop in sis.c gets it right according to | |
487 | my reading of the code. | |
488 | ||
489 | The bug is: if an interrupt happens when the next instruction | |
490 | (at sregs->pc) is annulled, the trap is taken (by execute_trap()) | |
491 | with the current values of PC and NPC, so when the trap returns, | |
492 | the annulled instruction is indeed executed. Another giveaway is | |
493 | that the annul flag is cleared in execute_trap(): the information | |
494 | is demonstrably discarded. | |
495 | ||
496 | The solution is: perform annulling before looking for traps, in | |
497 | fact it's neater to do annulling, see if there's an interrupt and | |
498 | if not, do the instruction, then handle traps be they generated by | |
499 | interrupts pending or by the instruction we might just have done. | |
500 | That's what the sis.c one does. | |
501 | ||
502 | 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk> | |
503 | ||
504 | * sis.h: Add asr17 register for support of SparcLITE (at least the | |
505 | Hitachi ones I find before me) | |
506 | ||
507 | * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if | |
508 | sparclite. Other ASR numbers than 17 or 0 (Y) trap out. | |
509 | Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto. | |
510 | (execute_trap): Do single-vector-trapping if asr17 bit 0 is set. | |
511 | (init_regs): Initialize y and asr17. | |
512 | NB: In instruction-set space, the Y register is asr0; the | |
513 | instructions have different names for human reasons only. | |
514 | ||
515 | * sis.c: | |
516 | * interf.c: Set boolean mode variable dumbio if invoked with | |
517 | argument "-dumbio" and mention it of verbose. | |
518 | * erc32.c: if "dumbio" is set, do not assume that there is a | |
519 | terminal type device attached to stdin/stdout. Do not set | |
520 | buffering or mess with tcsetattr or do any read operations in | |
521 | order to make UART interrupts; not input data is supported. | |
522 | This is necessary to allow the sim to be used within the eCos | |
523 | testing infrastructure where stdin/stdout are pipes to a TCL | |
524 | program; the sim hangs otherwise. | |

549 | error message for unrecognized option. | |

933 | Version 2.1 26-02-96 | |
934 | -------------------- | |
72f4393d | 935 | |
c906108c | 936 | * Fixed bug in "go" command. |
72f4393d | 937 | |
c906108c SS |
938 | version 2.0 05-02-96 |
939 | -------------------- | |
940 | ||
941 | * Fixed bug in interrupt force register (erc32.c). | |
942 | ||
943 | * Change file load function to use bfd_openr. | |
944 | ||
945 | * SIS should now be endian independent. | |
946 | ||
947 | version 1.8 24-11-95 | |
948 | -------------------- | |
949 | ||
950 | * Fixed FPU timing - some sequences of FPU instructions did not calculate | |
951 | the resource dependencies right. | |
952 | ||
953 | * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error | |
954 | but no FPU trap is generated. | |
955 | ||
956 | version 1.7.1 31-10-95 | |
957 | -------------------- | |
958 | ||
959 | * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but | |
960 | the FPU stays in execute mode. | |
961 | ||
962 | * Corrected JMPL and RETT timing (these instructions takes two cycles). | |
963 | ||
964 | ||
965 | version 1.7 25-10-95 | |
966 | -------------------- | |
967 | ||
968 | * Interrupt during annuled instruction corrupted return address - fixed. | |
969 | ||
970 | ||
971 | version 1.6.2 25-10-95 | |
972 | -------------------- | |
973 | ||
974 | * Added -DFAST_UART to Makefile | |
72f4393d | 975 | |
c906108c SS |
976 | |
977 | version 1.6.1 24-10-95 | |
978 | -------------------- | |
72f4393d | 979 | |
c906108c SS |
980 | * Fixed bug in STDFQ which caused bus error |
981 | ||
982 | ||
983 | version 1.6 02-10-95 | |
984 | -------------------- | |
72f4393d | 985 | |
c906108c SS |
986 | * Modified srt0.s to include code that initiates registers in IU and FPU |
987 | and initializes the data segment. The simulator 'load' command does not | |
988 | longer initialize the data segment! | |
989 | ||
72f4393d | 990 | * Corrected MEC timer operation; scalers now divide the frequency by |
c906108c SS |
991 | (scaler_value + 1). |
992 | ||
993 | * MEC breakpoints are not checked during store operation | |
994 | ||
995 | ||
996 | version 1.5 14-09-95 | |
997 | -------------------- | |
998 | ||
999 | * Fixed some bugs in the cycle counting for IU & FPU instructions. | |
1000 | ||
1001 | * Fixed bug that allowed an annuled instruction to cause memory exception. | |
1002 | ||
1003 | * The *ws parameter in mem.c should now contain the number of waitstates | |
1004 | required by the memory access (was total number of cycles). | |
1005 | ||
1006 | * The supplied srt0.s now clears the BSS (thanks Joel). | |
1007 | ||
1008 | version 1.4 22-08-95 | |
1009 | -------------------- | |
1010 | ||
1011 | * Added a '-g' switch to enable/disable the GNU readline(), which cause | |
1012 | some problems on solaris 2.x machines. | |
1013 | ||
72f4393d | 1014 | * Enabled MEC watchpoint and breakpoint function to mem.c. Performance |
c906108c SS |
1015 | may suffer a bit ... |
1016 | ||
1017 | NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd. | |
1018 | ||
1019 | version 1.3 26-07-95 | |
1020 | -------------------- | |
1021 | ||
1022 | * Fixed bug in mulscc instruction (how could that ever have worked?) | |
1023 | ||
1024 | * Fixed bug in UART B (flushed characters on UART A), thanks Paul. | |
1025 | ||
1026 | version 1.2 13-07-95 | |
1027 | -------------------- | |
1028 | ||
1029 | * Fixed bug in interrupt handling (wrong interrupt selected when more that | |
1030 | one interrupt pending) | |
1031 | ||
1032 | * Fixed updating of condition codes during logical instructions (carry and | |
1033 | overflow were not reset) | |
1034 | ||
1035 | * Fixed bug in WRTBR (tt field was wrongly over-written) | |
1036 | ||
1037 | version 1.1 07-07-95 | |
1038 | -------------------- | |
1039 | ||
1040 | * Fixed several bugs in the interrupt handler and callback routines. | |
1041 | (reported by Paul Warren, Alsys) |
