SS		 641999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
65
66 * exec.c (dispatch_instruction):
67 Correct the sense of the
68 if (!sparclite) {
69 sregs->trap = TRAP_UNIMP;
70 break;
71 }
72 clause that has been pasted around: it's correct in the SCAN and
73 DIVScc (divide step) cases (where it was probably originally
74 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
75 ie. instructions only in the SPARC V8 or SPARClite 86x
76 architectures. It was also present when not required for SMUL,
77 SMULcc, UMUL, UMULcc instructions that are present in all
78 architectures.
79
801999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
81
82 * interf.c (run_sim): Fix a bug in the main loop's handling of
83 annulled delay slot instructions. There is precedent for this
84 change; the _other_ main loop in sis.c gets it right according to
85 my reading of the code.
86
87 The bug is: if an interrupt happens when the next instruction
88 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
89 with the current values of PC and NPC, so when the trap returns,
90 the annulled instruction is indeed executed. Another giveaway is
91 that the annul flag is cleared in execute_trap(): the information
92 is demonstrably discarded.
93
94 The solution is: perform annulling before looking for traps, in
95 fact it's neater to do annulling, see if there's an interrupt and
96 if not, do the instruction, then handle traps be they generated by
97 interrupts pending or by the instruction we might just have done.
98 That's what the sis.c one does.
99
1001999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
101
102 * sis.h: Add asr17 register for support of SparcLITE (at least the
103 Hitachi ones I find before me)
104
105 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
106 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
107 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
108 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
109 (init_regs): Initialize y and asr17.
110 NB: In instruction-set space, the Y register is asr0; the
111 instructions have different names for human reasons only.
112
113 * sis.c:
114 * interf.c: Set boolean mode variable dumbio if invoked with
115 argument "-dumbio" and mention it of verbose.
116 * erc32.c: if "dumbio" is set, do not assume that there is a
117 terminal type device attached to stdin/stdout. Do not set
118 buffering or mess with tcsetattr or do any read operations in
119 order to make UART interrupts; not input data is supported.
120 This is necessary to allow the sim to be used within the eCos
121 testing infrastructure where stdin/stdout are pipes to a TCL
122 program; the sim hangs otherwise.
123
124Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>
125
126 * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
127
128Tue Jul 7 21:12:41 1998 Mark Alexander <marka@cygnus.com>
129

134 * func.c (bfd_load): Print correct endianness.
135 * interf.c (run_sim): Print debugging information if verbosity level

140 is greater then 2.
141
142Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
143
144 * interf.c (sim_open): Use revamped memory_read, which makes
145 byte-swapping unnecessary. Add -sparclite-board option for
146 emulating RAM found on typical SPARClite boards. Print
147 error message for unrecognized option.
148 * erc32.c: Change RAM address and size from constants to variables,
149 to allow emulation of SPARClite board RAM.
150 (fetch_bytes, store_bytes): New helper functions for revamped
151 mememory_read and memory_write.
152 (memory_read, memory_write): Rewrite to store bytes in target
153 byte order instead of storing words in host byte order; this
154 greatly simplifies support of little-endian programs.
155 (get_mem_ptr): Remove unnecessary byte parameter.
156 (sis_memory_write, sis_memory_read): Store words in target
157 byte order instead of host byte order.

159 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
160 (memory_read): Add new sz parameter.
161 * sis.c (run_sim): Use revamped memory_read, which makes
162 byte-swapping unnecessary.
163 * exec.c (dispatch_instruction): Use revamped memory_read, which
164 makes byte-swapping and double-word fetching unnecessary.
165 * func.c (sparclite_board): Declare new variable.
166 (get_regi): Handle little-endian data.
167 (bfd_load): Recognize little-endian SPARClite as having
168 little-endian data.

185Wed May 13 14:59:54 1998 Mark Alexander <marka@cygnus.com>
186

188 (byte_swap_words): New function.
189 * sis.h: (byte_swap_words): Declare.
190 * interf.c (run_sim): Always fetch instructions as big-endian.

473 there either...).
474
475Mon Aug 12 17:04:58 1996 Stu Grossman (grossman@critters.cygnus.com)
476
477 * erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't
478 necessary.

521
522 * Makefile.in (end.h): Use explicit ./ when running end.
523
524Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
525
526 * func.c(bfd_load): Don't try to print the filename if the pfbd is
527 NULL.
528 * interf.c(sim_load): Pass the whole string, not just the first
529 byte.
530
531Version 2.1 26-02-96
532--------------------
533
534* Fixed bug in "go" command.
535
536version 2.0 05-02-96
537--------------------
538
539* Fixed bug in interrupt force register (erc32.c).
540
541* Change file load function to use bfd_openr.
542
543* SIS should now be endian independent.
544
545version 1.8 24-11-95
546--------------------
547
548* Fixed FPU timing - some sequences of FPU instructions did not calculate
549 the resource dependencies right.
550
551* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
552 but no FPU trap is generated.
553
554version 1.7.1 31-10-95
555--------------------
556
557* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
558 the FPU stays in execute mode.
559
560* Corrected JMPL and RETT timing (these instructions takes two cycles).
561
562
563version 1.7 25-10-95
564--------------------
565
566* Interrupt during annuled instruction corrupted return address - fixed.
567
568
569version 1.6.2 25-10-95
570--------------------
571
572* Added -DFAST_UART to Makefile
573
574
575version 1.6.1 24-10-95
576--------------------
577
578* Fixed bug in STDFQ which caused bus error
579
580
581version 1.6 02-10-95
582--------------------
583
584* Modified srt0.s to include code that initiates registers in IU and FPU
585 and initializes the data segment. The simulator 'load' command does not
586 longer initialize the data segment!
587
588* Corrected MEC timer operation; scalers now divide the frequency by
589 (scaler_value + 1).
590
591* MEC breakpoints are not checked during store operation
592
593
594version 1.5 14-09-95
595--------------------
596
597* Fixed some bugs in the cycle counting for IU & FPU instructions.
598
599* Fixed bug that allowed an annuled instruction to cause memory exception.
600
601* The *ws parameter in mem.c should now contain the number of waitstates
602 required by the memory access (was total number of cycles).
603
604* The supplied srt0.s now clears the BSS (thanks Joel).
605
606version 1.4 22-08-95
607--------------------
608
609* Added a '-g' switch to enable/disable the GNU readline(), which cause
610some problems on solaris 2.x machines.
611
612* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
613may suffer a bit ...
614
615NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
616
617version 1.3 26-07-95
618--------------------
619
620* Fixed bug in mulscc instruction (how could that ever have worked?)
621
622* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
623
624version 1.2 13-07-95
625--------------------
626
627* Fixed bug in interrupt handling (wrong interrupt selected when more that
628one interrupt pending)
629
630* Fixed updating of condition codes during logical instructions (carry and
631overflow were not reset)
632
633* Fixed bug in WRTBR (tt field was wrongly over-written)
634
635version 1.1 07-07-95
636--------------------
637
638* Fixed several bugs in the interrupt handler and callback routines.
