694 * configure: regenerate
696 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
698 * exec.c (dispatch_instruction):
699 Correct the sense of the
701 sregs->trap = TRAP_UNIMP;
704 clause that has been pasted around: it's correct in the SCAN and
705 DIVScc (divide step) cases (where it was probably originally
706 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
707 ie. instructions only in the SPARC V8 or SPARClite 86x
708 architectures. It was also present when not required for SMUL,
709 SMULcc, UMUL, UMULcc instructions that are present in all
712 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
714 * interf.c (run_sim): Fix a bug in the main loop's handling of
715 annulled delay slot instructions. There is precedent for this
716 change; the _other_ main loop in sis.c gets it right according to
717 my reading of the code.
719 The bug is: if an interrupt happens when the next instruction
720 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
721 with the current values of PC and NPC, so when the trap returns,
722 the annulled instruction is indeed executed. Another giveaway is
723 that the annul flag is cleared in execute_trap(): the information
724 is demonstrably discarded.
726 The solution is: perform annulling before looking for traps, in
727 fact it's neater to do annulling, see if there's an interrupt and
728 if not, do the instruction, then handle traps be they generated by
729 interrupts pending or by the instruction we might just have done.
730 That's what the sis.c one does.
732 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
734 * sis.h: Add asr17 register for support of SparcLITE (at least the
735 Hitachi ones I find before me)
737 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
738 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
739 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
740 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
741 (init_regs): Initialize y and asr17.
742 NB: In instruction-set space, the Y register is asr0; the
743 instructions have different names for human reasons only.
746 * interf.c: Set boolean mode variable dumbio if invoked with
747 argument "-dumbio" and mention it of verbose.
748 * erc32.c: if "dumbio" is set, do not assume that there is a
749 terminal type device attached to stdin/stdout. Do not set
750 buffering or mess with tcsetattr or do any read operations in
751 order to make UART interrupts; not input data is supported.
752 This is necessary to allow the sim to be used within the eCos
753 testing infrastructure where stdin/stdout are pipes to a TCL
754 program; the sim hangs otherwise.
756 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

774 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
776 * interf.c (sim_open): Use revamped memory_read, which makes
777 byte-swapping unnecessary. Add -sparclite-board option for
778 emulating RAM found on typical SPARClite boards. Print
779 error message for unrecognized option.
780 * erc32.c: Change RAM address and size from constants to variables,
781 to allow emulation of SPARClite board RAM.
782 (fetch_bytes, store_bytes): New helper functions for revamped
783 mememory_read and memory_write.
784 (memory_read, memory_write): Rewrite to store bytes in target
785 byte order instead of storing words in host byte order; this
786 greatly simplifies support of little-endian programs.
787 (get_mem_ptr): Remove unnecessary byte parameter.
788 (sis_memory_write, sis_memory_read): Store words in target
789 byte order instead of host byte order.

791 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
792 (memory_read): Add new sz parameter.
793 * sis.c (run_sim): Use revamped memory_read, which makes
794 byte-swapping unnecessary.
795 * exec.c (dispatch_instruction): Use revamped memory_read, which
796 makes byte-swapping and double-word fetching unnecessary.
797 * func.c (sparclite_board): Declare new variable.

820 (byte_swap_words): New function.
821 * sis.h: (byte_swap_words): Declare.
822 * interf.c (run_sim): Always fetch instructions as big-endian.

1140 * configure: Rebuilt.
1142 Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
1144 * configure.in: Call AC_PROG_CC before running configure.host.
1145 * configure: Rebuild with autoconf 2.10.
1147 Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
1149 * Makefile.in (install): Don't check to see if tooldir exists.
1150 Make $(tooldir) and $(tooldir)/bin.
1152 Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
1154 * Makefile.in (end.h): Use explicit ./ when running end.
1156 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
1158 * func.c(bfd_load): Don't try to print the filename if the pfbd is
1160 * interf.c(sim_load): Pass the whole string, not just the first
1163 Version 2.1 26-02-96
1164 --------------------
1166 * Fixed bug in "go" command.
1168 version 2.0 05-02-96
1169 --------------------
1171 * Fixed bug in interrupt force register (erc32.c).
1173 * Change file load function to use bfd_openr.
1175 * SIS should now be endian independent.
1177 version 1.8 24-11-95
1178 --------------------
1180 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1181 the resource dependencies right.
1183 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1184 but no FPU trap is generated.
1186 version 1.7.1 31-10-95
1187 --------------------
1189 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1190 the FPU stays in execute mode.
1192 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1195 version 1.7 25-10-95
1196 --------------------
1198 * Interrupt during annuled instruction corrupted return address - fixed.
1201 version 1.6.2 25-10-95
1202 --------------------
1204 * Added -DFAST_UART to Makefile
1207 version 1.6.1 24-10-95
1208 --------------------
1210 * Fixed bug in STDFQ which caused bus error
1213 version 1.6 02-10-95
1214 --------------------
1216 * Modified srt0.s to include code that initiates registers in IU and FPU
1217 and initializes the data segment. The simulator 'load' command does not
1218 longer initialize the data segment!
1220 * Corrected MEC timer operation; scalers now divide the frequency by
1223 * MEC breakpoints are not checked during store operation
1226 version 1.5 14-09-95
1227 --------------------
1229 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1231 * Fixed bug that allowed an annuled instruction to cause memory exception.
1233 * The *ws parameter in mem.c should now contain the number of waitstates
1234 required by the memory access (was total number of cycles).
1236 * The supplied srt0.s now clears the BSS (thanks Joel).
1238 version 1.4 22-08-95
1239 --------------------
1241 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1242 some problems on solaris 2.x machines.
1244 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1245 may suffer a bit ...
1247 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1249 version 1.3 26-07-95
1250 --------------------
1252 * Fixed bug in mulscc instruction (how could that ever have worked?)
1254 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1256 version 1.2 13-07-95
1257 --------------------
1259 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1260 one interrupt pending)
1262 * Fixed updating of condition codes during logical instructions (carry and
1263 overflow were not reset)
1265 * Fixed bug in WRTBR (tt field was wrongly over-written)
1267 version 1.1 07-07-95
1268 --------------------
1270 * Fixed several bugs in the interrupt handler and callback routines.
