680 * configure: regenerate
682 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
684 * exec.c (dispatch_instruction):
685 Correct the sense of the
687 sregs->trap = TRAP_UNIMP;
690 clause that has been pasted around: it's correct in the SCAN and
691 DIVScc (divide step) cases (where it was probably originally
692 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
693 ie. instructions only in the SPARC V8 or SPARClite 86x
694 architectures. It was also present when not required for SMUL,
695 SMULcc, UMUL, UMULcc instructions that are present in all
698 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
700 * interf.c (run_sim): Fix a bug in the main loop's handling of
701 annulled delay slot instructions. There is precedent for this
702 change; the _other_ main loop in sis.c gets it right according to
703 my reading of the code.
705 The bug is: if an interrupt happens when the next instruction
706 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
707 with the current values of PC and NPC, so when the trap returns,
708 the annulled instruction is indeed executed. Another giveaway is
709 that the annul flag is cleared in execute_trap(): the information
710 is demonstrably discarded.
712 The solution is: perform annulling before looking for traps, in
713 fact it's neater to do annulling, see if there's an interrupt and
714 if not, do the instruction, then handle traps be they generated by
715 interrupts pending or by the instruction we might just have done.
716 That's what the sis.c one does.
718 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
720 * sis.h: Add asr17 register for support of SparcLITE (at least the
721 Hitachi ones I find before me)
723 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
724 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
725 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
726 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
727 (init_regs): Initialize y and asr17.
728 NB: In instruction-set space, the Y register is asr0; the
729 instructions have different names for human reasons only.
732 * interf.c: Set boolean mode variable dumbio if invoked with
733 argument "-dumbio" and mention it of verbose.
734 * erc32.c: if "dumbio" is set, do not assume that there is a
735 terminal type device attached to stdin/stdout. Do not set
736 buffering or mess with tcsetattr or do any read operations in
737 order to make UART interrupts; not input data is supported.
738 This is necessary to allow the sim to be used within the eCos
739 testing infrastructure where stdin/stdout are pipes to a TCL
740 program; the sim hangs otherwise.
742 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

760 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
762 * interf.c (sim_open): Use revamped memory_read, which makes
763 byte-swapping unnecessary. Add -sparclite-board option for
764 emulating RAM found on typical SPARClite boards. Print
765 error message for unrecognized option.
766 * erc32.c: Change RAM address and size from constants to variables,
767 to allow emulation of SPARClite board RAM.
768 (fetch_bytes, store_bytes): New helper functions for revamped
769 mememory_read and memory_write.

771 byte order instead of storing words in host byte order; this
772 greatly simplifies support of little-endian programs.

774 (sis_memory_write, sis_memory_read): Store words in target
775 byte order instead of host byte order.

777 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
778 (memory_read): Add new sz parameter.
779 * sis.c (run_sim): Use revamped memory_read, which makes
780 byte-swapping unnecessary.
781 * exec.c (dispatch_instruction): Use revamped memory_read, which
782 makes byte-swapping and double-word fetching unnecessary.

1140 * Makefile.in (end.h): Use explicit ./ when running end.
1142 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
1144 * func.c(bfd_load): Don't try to print the filename if the pfbd is
1146 * interf.c(sim_load): Pass the whole string, not just the first
1149 Version 2.1 26-02-96
1150 --------------------
1152 * Fixed bug in "go" command.
1154 version 2.0 05-02-96
1155 --------------------
1157 * Fixed bug in interrupt force register (erc32.c).
1159 * Change file load function to use bfd_openr.
1161 * SIS should now be endian independent.
1163 version 1.8 24-11-95
1164 --------------------
1166 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1167 the resource dependencies right.
1169 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1170 but no FPU trap is generated.
1172 version 1.7.1 31-10-95
1173 --------------------
1175 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1176 the FPU stays in execute mode.
1178 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1181 version 1.7 25-10-95
1182 --------------------
1184 * Interrupt during annuled instruction corrupted return address - fixed.
1187 version 1.6.2 25-10-95
1188 --------------------
1190 * Added -DFAST_UART to Makefile
1193 version 1.6.1 24-10-95
1194 --------------------
1196 * Fixed bug in STDFQ which caused bus error
1199 version 1.6 02-10-95
1200 --------------------
1202 * Modified srt0.s to include code that initiates registers in IU and FPU
1203 and initializes the data segment. The simulator 'load' command does not
1204 longer initialize the data segment!
1206 * Corrected MEC timer operation; scalers now divide the frequency by
1209 * MEC breakpoints are not checked during store operation
1212 version 1.5 14-09-95
1213 --------------------
1215 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1217 * Fixed bug that allowed an annuled instruction to cause memory exception.
1219 * The *ws parameter in mem.c should now contain the number of waitstates
1220 required by the memory access (was total number of cycles).
1222 * The supplied srt0.s now clears the BSS (thanks Joel).
1224 version 1.4 22-08-95
1225 --------------------
1227 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1228 some problems on solaris 2.x machines.
1230 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1231 may suffer a bit ...
1233 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1235 version 1.3 26-07-95
1236 --------------------
1238 * Fixed bug in mulscc instruction (how could that ever have worked?)
1240 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1242 version 1.2 13-07-95
1243 --------------------
1245 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1246 one interrupt pending)
1248 * Fixed updating of condition codes during logical instructions (carry and
1249 overflow were not reset)
1251 * Fixed bug in WRTBR (tt field was wrongly over-written)
1253 version 1.1 07-07-95
1254 --------------------
1256 * Fixed several bugs in the interrupt handler and callback routines.
