101 * configure: regenerate
103 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
105 * exec.c (dispatch_instruction):
106 Correct the sense of the
108 sregs->trap = TRAP_UNIMP;
111 clause that has been pasted around: it's correct in the SCAN and
112 DIVScc (divide step) cases (where it was probably originally
113 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
114 ie. instructions only in the SPARC V8 or SPARClite 86x
115 architectures. It was also present when not required for SMUL,
116 SMULcc, UMUL, UMULcc instructions that are present in all
119 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
121 * interf.c (run_sim): Fix a bug in the main loop's handling of
122 annulled delay slot instructions. There is precedent for this
123 change; the _other_ main loop in sis.c gets it right according to
124 my reading of the code.
126 The bug is: if an interrupt happens when the next instruction
127 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
128 with the current values of PC and NPC, so when the trap returns,
129 the annulled instruction is indeed executed. Another giveaway is
130 that the annul flag is cleared in execute_trap(): the information
131 is demonstrably discarded.
133 The solution is: perform annulling before looking for traps, in
134 fact it's neater to do annulling, see if there's an interrupt and
135 if not, do the instruction, then handle traps be they generated by
136 interrupts pending or by the instruction we might just have done.
137 That's what the sis.c one does.
139 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
141 * sis.h: Add asr17 register for support of SparcLITE (at least the
142 Hitachi ones I find before me)
144 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
145 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
146 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
147 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
148 (init_regs): Initialize y and asr17.
149 NB: In instruction-set space, the Y register is asr0; the
150 instructions have different names for human reasons only.
153 * interf.c: Set boolean mode variable dumbio if invoked with
154 argument "-dumbio" and mention it of verbose.
155 * erc32.c: if "dumbio" is set, do not assume that there is a
156 terminal type device attached to stdin/stdout. Do not set
157 buffering or mess with tcsetattr or do any read operations in
158 order to make UART interrupts; not input data is supported.
159 This is necessary to allow the sim to be used within the eCos
160 testing infrastructure where stdin/stdout are pipes to a TCL
161 program; the sim hangs otherwise.
163 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

181 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
183 * interf.c (sim_open): Use revamped memory_read, which makes
184 byte-swapping unnecessary. Add -sparclite-board option for
185 emulating RAM found on typical SPARClite boards. Print
186 error message for unrecognized option.
187 * erc32.c: Change RAM address and size from constants to variables,
188 to allow emulation of SPARClite board RAM.
189 (fetch_bytes, store_bytes): New helper functions for revamped
190 mememory_read and memory_write.
191 (memory_read, memory_write): Rewrite to store bytes in target
192 byte order instead of storing words in host byte order; this
193 greatly simplifies support of little-endian programs.
194 (get_mem_ptr): Remove unnecessary byte parameter.
195 (sis_memory_write, sis_memory_read): Store words in target
196 byte order instead of host byte order.
197 (byte_swap_words): Remove, no longer needed.
198 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
199 (memory_read): Add new sz parameter.
200 * sis.c (run_sim): Use revamped memory_read, which makes
201 byte-swapping unnecessary.
202 * exec.c (dispatch_instruction): Use revamped memory_read, which
203 makes byte-swapping and double-word fetching unnecessary.
204 * func.c (sparclite_board): Declare new variable.

543 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
544 (docdir, oldincludedir): Removed.
545 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
546 (AC_PROG_INSTALL): Added.
547 * configure: Rebuilt.
549 Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
551 * configure.in: Call AC_PROG_CC before running configure.host.
552 * configure: Rebuild with autoconf 2.10.
554 Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
556 * Makefile.in (install): Don't check to see if tooldir exists.
557 Make $(tooldir) and $(tooldir)/bin.
559 Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
561 * Makefile.in (end.h): Use explicit ./ when running end.
563 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
565 * func.c(bfd_load): Don't try to print the filename if the pfbd is
567 * interf.c(sim_load): Pass the whole string, not just the first
573 * Fixed bug in "go" command.
578 * Fixed bug in interrupt force register (erc32.c).
580 * Change file load function to use bfd_openr.
582 * SIS should now be endian independent.
587 * Fixed FPU timing - some sequences of FPU instructions did not calculate
588 the resource dependencies right.
590 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
591 but no FPU trap is generated.
593 version 1.7.1 31-10-95
596 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
597 the FPU stays in execute mode.
599 * Corrected JMPL and RETT timing (these instructions takes two cycles).
605 * Interrupt during annuled instruction corrupted return address - fixed.
608 version 1.6.2 25-10-95
611 * Added -DFAST_UART to Makefile
614 version 1.6.1 24-10-95
617 * Fixed bug in STDFQ which caused bus error
623 * Modified srt0.s to include code that initiates registers in IU and FPU
624 and initializes the data segment. The simulator 'load' command does not
625 longer initialize the data segment!
627 * Corrected MEC timer operation; scalers now divide the frequency by
630 * MEC breakpoints are not checked during store operation
636 * Fixed some bugs in the cycle counting for IU & FPU instructions.
638 * Fixed bug that allowed an annuled instruction to cause memory exception.
640 * The *ws parameter in mem.c should now contain the number of waitstates
641 required by the memory access (was total number of cycles).
643 * The supplied srt0.s now clears the BSS (thanks Joel).
648 * Added a '-g' switch to enable/disable the GNU readline(), which cause
649 some problems on solaris 2.x machines.
651 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
654 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
659 * Fixed bug in mulscc instruction (how could that ever have worked?)
661 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
666 * Fixed bug in interrupt handling (wrong interrupt selected when more that
667 one interrupt pending)
669 * Fixed updating of condition codes during logical instructions (carry and
670 overflow were not reset)
672 * Fixed bug in WRTBR (tt field was wrongly over-written)
677 * Fixed several bugs in the interrupt handler and callback routines.
