SS		 101999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
11
12 * exec.c (dispatch_instruction):
13 Correct the sense of the
14 if (!sparclite) {
15 sregs->trap = TRAP_UNIMP;
16 break;
17 }
18 clause that has been pasted around: it's correct in the SCAN and
19 DIVScc (divide step) cases (where it was probably originally
20 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
21 ie. instructions only in the SPARC V8 or SPARClite 86x
22 architectures. It was also present when not required for SMUL,
23 SMULcc, UMUL, UMULcc instructions that are present in all
24 architectures.
25
261999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
27
28 * interf.c (run_sim): Fix a bug in the main loop's handling of
29 annulled delay slot instructions. There is precedent for this
30 change; the _other_ main loop in sis.c gets it right according to
31 my reading of the code.
32
33 The bug is: if an interrupt happens when the next instruction
34 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
35 with the current values of PC and NPC, so when the trap returns,
36 the annulled instruction is indeed executed. Another giveaway is
37 that the annul flag is cleared in execute_trap(): the information
38 is demonstrably discarded.
39
40 The solution is: perform annulling before looking for traps, in
41 fact it's neater to do annulling, see if there's an interrupt and
42 if not, do the instruction, then handle traps be they generated by
43 interrupts pending or by the instruction we might just have done.
44 That's what the sis.c one does.

461999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
47
48 * sis.h: Add asr17 register for support of SparcLITE (at least the
49 Hitachi ones I find before me)
50
51 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
52 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
53 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
54 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
55 (init_regs): Initialize y and asr17.
56 NB: In instruction-set space, the Y register is asr0; the
57 instructions have different names for human reasons only.
58
59 * sis.c:
60 * interf.c: Set boolean mode variable dumbio if invoked with
61 argument "-dumbio" and mention it of verbose.
62 * erc32.c: if "dumbio" is set, do not assume that there is a
63 terminal type device attached to stdin/stdout. Do not set
64 buffering or mess with tcsetattr or do any read operations in
65 order to make UART interrupts; not input data is supported.
66 This is necessary to allow the sim to be used within the eCos
67 testing infrastructure where stdin/stdout are pipes to a TCL
68 program; the sim hangs otherwise.
69
70Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>
71
72 * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.

87
88Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
89
90 * interf.c (sim_open): Use revamped memory_read, which makes
91 byte-swapping unnecessary. Add -sparclite-board option for
92 emulating RAM found on typical SPARClite boards. Print
93 error message for unrecognized option.
94 * erc32.c: Change RAM address and size from constants to variables,
95 to allow emulation of SPARClite board RAM.
96 (fetch_bytes, store_bytes): New helper functions for revamped
97 mememory_read and memory_write.
98 (memory_read, memory_write): Rewrite to store bytes in target
99 byte order instead of storing words in host byte order; this
100 greatly simplifies support of little-endian programs.
101 (get_mem_ptr): Remove unnecessary byte parameter.
102 (sis_memory_write, sis_memory_read): Store words in target
103 byte order instead of host byte order.

106 (memory_read): Add new sz parameter.
107 * sis.c (run_sim): Use revamped memory_read, which makes
108 byte-swapping unnecessary.
109 * exec.c (dispatch_instruction): Use revamped memory_read, which
110 makes byte-swapping and double-word fetching unnecessary.
111 * func.c (sparclite_board): Declare new variable.
112 (get_regi): Handle little-endian data.
113 (bfd_load): Recognize little-endian SPARClite as having
114 little-endian data.

135 * sis.h: (byte_swap_words): Declare.
136 * interf.c (run_sim): Always fetch instructions as big-endian.

449 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
450 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
451 (docdir, oldincludedir): Removed.
452 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
453 (AC_PROG_INSTALL): Added.
454 * configure: Rebuilt.
455
456Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
457
458 * configure.in: Call AC_PROG_CC before running configure.host.
459 * configure: Rebuild with autoconf 2.10.
460
461Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
462
463 * Makefile.in (install): Don't check to see if tooldir exists.
464 Make $(tooldir) and $(tooldir)/bin.
465
466Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
467
468 * Makefile.in (end.h): Use explicit ./ when running end.

470Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
471
472 * func.c(bfd_load): Don't try to print the filename if the pfbd is
473 NULL.
474 * interf.c(sim_load): Pass the whole string, not just the first
475 byte.
476
477Version 2.1 26-02-96
478--------------------
479
480* Fixed bug in "go" command.
481
482version 2.0 05-02-96
483--------------------
484
485* Fixed bug in interrupt force register (erc32.c).
486
487* Change file load function to use bfd_openr.
488
489* SIS should now be endian independent.
490
491version 1.8 24-11-95
492--------------------
493
494* Fixed FPU timing - some sequences of FPU instructions did not calculate
495 the resource dependencies right.
496
497* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
498 but no FPU trap is generated.
499
500version 1.7.1 31-10-95
501--------------------
502
503* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
504 the FPU stays in execute mode.
505
506* Corrected JMPL and RETT timing (these instructions takes two cycles).
507
508
509version 1.7 25-10-95
510--------------------
511
512* Interrupt during annuled instruction corrupted return address - fixed.
513
514
515version 1.6.2 25-10-95
516--------------------
517
518* Added -DFAST_UART to Makefile
519
520
521version 1.6.1 24-10-95
522--------------------
523
524* Fixed bug in STDFQ which caused bus error
525
526
527version 1.6 02-10-95
528--------------------
529
530* Modified srt0.s to include code that initiates registers in IU and FPU
531 and initializes the data segment. The simulator 'load' command does not
532 longer initialize the data segment!
533
534* Corrected MEC timer operation; scalers now divide the frequency by
535 (scaler_value + 1).
536
537* MEC breakpoints are not checked during store operation
538
539
540version 1.5 14-09-95
541--------------------
542
543* Fixed some bugs in the cycle counting for IU & FPU instructions.
544
545* Fixed bug that allowed an annuled instruction to cause memory exception.
546
547* The *ws parameter in mem.c should now contain the number of waitstates
548 required by the memory access (was total number of cycles).
549
550* The supplied srt0.s now clears the BSS (thanks Joel).
551
552version 1.4 22-08-95
553--------------------
554
555* Added a '-g' switch to enable/disable the GNU readline(), which cause
556some problems on solaris 2.x machines.
557
558* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
559may suffer a bit ...
560
561NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
562
563version 1.3 26-07-95
564--------------------
565
566* Fixed bug in mulscc instruction (how could that ever have worked?)
567
568* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
569
570version 1.2 13-07-95
571--------------------
572
573* Fixed bug in interrupt handling (wrong interrupt selected when more that
574one interrupt pending)
575
576* Fixed updating of condition codes during logical instructions (carry and
577overflow were not reset)
578
579* Fixed bug in WRTBR (tt field was wrongly over-written)
580
581version 1.1 07-07-95
582--------------------
583
584* Fixed several bugs in the interrupt handler and callback routines.
