| 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. |
| 16 | |
| 17 | 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk> |
| 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. |
| 60 | |
| 61 | Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com> |

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

| 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. |
| 423 | * Get rid of enum sim_stop. It's defined in remote-sim.h. |

| 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) |

| 451 | |
| 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. |
| 576 | (reported by Paul Warren, Alsys) |
