135 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
137 * exec.c (dispatch_instruction):
138 Correct the sense of the
140 sregs->trap = TRAP_UNIMP;
143 clause that has been pasted around: it's correct in the SCAN and
144 DIVScc (divide step) cases (where it was probably originally
145 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
146 ie. instructions only in the SPARC V8 or SPARClite 86x
147 architectures. It was also present when not required for SMUL,
148 SMULcc, UMUL, UMULcc instructions that are present in all
151 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
153 * interf.c (run_sim): Fix a bug in the main loop's handling of
154 annulled delay slot instructions. There is precedent for this
155 change; the _other_ main loop in sis.c gets it right according to
156 my reading of the code.
158 The bug is: if an interrupt happens when the next instruction
159 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
160 with the current values of PC and NPC, so when the trap returns,
161 the annulled instruction is indeed executed. Another giveaway is
162 that the annul flag is cleared in execute_trap(): the information
163 is demonstrably discarded.
165 The solution is: perform annulling before looking for traps, in
166 fact it's neater to do annulling, see if there's an interrupt and
167 if not, do the instruction, then handle traps be they generated by
168 interrupts pending or by the instruction we might just have done.
169 That's what the sis.c one does.
171 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
173 * sis.h: Add asr17 register for support of SparcLITE (at least the
174 Hitachi ones I find before me)
176 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
177 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
178 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
179 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
180 (init_regs): Initialize y and asr17.
181 NB: In instruction-set space, the Y register is asr0; the
182 instructions have different names for human reasons only.
185 * interf.c: Set boolean mode variable dumbio if invoked with
186 argument "-dumbio" and mention it of verbose.
187 * erc32.c: if "dumbio" is set, do not assume that there is a
188 terminal type device attached to stdin/stdout. Do not set
189 buffering or mess with tcsetattr or do any read operations in
190 order to make UART interrupts; not input data is supported.
191 This is necessary to allow the sim to be used within the eCos
192 testing infrastructure where stdin/stdout are pipes to a TCL
193 program; the sim hangs otherwise.

213 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
215 * interf.c (sim_open): Use revamped memory_read, which makes
216 byte-swapping unnecessary. Add -sparclite-board option for
217 emulating RAM found on typical SPARClite boards. Print
218 error message for unrecognized option.
219 * erc32.c: Change RAM address and size from constants to variables,
220 to allow emulation of SPARClite board RAM.
221 (fetch_bytes, store_bytes): New helper functions for revamped
222 mememory_read and memory_write.
223 (memory_read, memory_write): Rewrite to store bytes in target
224 byte order instead of storing words in host byte order; this
225 greatly simplifies support of little-endian programs.

227 (sis_memory_write, sis_memory_read): Store words in target
228 byte order instead of host byte order.
229 (byte_swap_words): Remove, no longer needed.
230 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
231 (memory_read): Add new sz parameter.
232 * sis.c (run_sim): Use revamped memory_read, which makes
233 byte-swapping unnecessary.
234 * exec.c (dispatch_instruction): Use revamped memory_read, which
235 makes byte-swapping and double-word fetching unnecessary.

553 * interf.c (sim_open): Cast fprintf to (fprintf_ftype) to fix
555 * (sim_load sim_create_inferior sim_read): Use prototypes only in
557 * Get rid of enum sim_stop. It's defined in remote-sim.h.
558 * (sim_stop_reason): Define SIGTRAP if _WIN32.
559 * sis.h: Include ansidecl.h and remote-sim.h.
561 Wed Jul 3 16:05:23 1996 Stu Grossman (grossman@critters.cygnus.com)
563 * erc32.c (mec_reset mec_read mec_write memory_read memory_write),
564 sis.h: Get rid of all uses of long long's.
565 * (close_port read_uart write_uart uarta_tx): Don't seg fault
566 when can't open pty's.
567 * exec.c: Add two new instructions: smul, and divscc.
568 * interf.c (flush_windows): New routine to flush the register
569 windows out to the stack just before returning to GDB. Makes
570 backtraces work much better.
572 Wed Jun 26 12:19:11 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
574 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
575 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
576 (docdir, oldincludedir): Removed.
577 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
578 (AC_PROG_INSTALL): Added.
579 * configure: Rebuilt.
581 Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
583 * configure.in: Call AC_PROG_CC before running configure.host.
584 * configure: Rebuild with autoconf 2.10.
586 Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
588 * Makefile.in (install): Don't check to see if tooldir exists.
589 Make $(tooldir) and $(tooldir)/bin.
591 Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
593 * Makefile.in (end.h): Use explicit ./ when running end.
595 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
597 * func.c(bfd_load): Don't try to print the filename if the pfbd is
599 * interf.c(sim_load): Pass the whole string, not just the first
605 * Fixed bug in "go" command.
610 * Fixed bug in interrupt force register (erc32.c).
612 * Change file load function to use bfd_openr.
614 * SIS should now be endian independent.
619 * Fixed FPU timing - some sequences of FPU instructions did not calculate
620 the resource dependencies right.
622 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
623 but no FPU trap is generated.
625 version 1.7.1 31-10-95
628 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
629 the FPU stays in execute mode.
631 * Corrected JMPL and RETT timing (these instructions takes two cycles).
637 * Interrupt during annuled instruction corrupted return address - fixed.
640 version 1.6.2 25-10-95
643 * Added -DFAST_UART to Makefile
646 version 1.6.1 24-10-95
649 * Fixed bug in STDFQ which caused bus error
655 * Modified srt0.s to include code that initiates registers in IU and FPU
656 and initializes the data segment. The simulator 'load' command does not
657 longer initialize the data segment!
659 * Corrected MEC timer operation; scalers now divide the frequency by
662 * MEC breakpoints are not checked during store operation
668 * Fixed some bugs in the cycle counting for IU & FPU instructions.
670 * Fixed bug that allowed an annuled instruction to cause memory exception.
672 * The *ws parameter in mem.c should now contain the number of waitstates
673 required by the memory access (was total number of cycles).
675 * The supplied srt0.s now clears the BSS (thanks Joel).
680 * Added a '-g' switch to enable/disable the GNU readline(), which cause
681 some problems on solaris 2.x machines.
683 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
686 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
691 * Fixed bug in mulscc instruction (how could that ever have worked?)
693 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
698 * Fixed bug in interrupt handling (wrong interrupt selected when more that
699 one interrupt pending)
701 * Fixed updating of condition codes during logical instructions (carry and
702 overflow were not reset)
704 * Fixed bug in WRTBR (tt field was wrongly over-written)
709 * Fixed several bugs in the interrupt handler and callback routines.
