174 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
176 * exec.c (dispatch_instruction):
177 Correct the sense of the
179 sregs->trap = TRAP_UNIMP;
182 clause that has been pasted around: it's correct in the SCAN and
183 DIVScc (divide step) cases (where it was probably originally
184 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
185 ie. instructions only in the SPARC V8 or SPARClite 86x
186 architectures. It was also present when not required for SMUL,
187 SMULcc, UMUL, UMULcc instructions that are present in all
190 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
192 * interf.c (run_sim): Fix a bug in the main loop's handling of
193 annulled delay slot instructions. There is precedent for this
194 change; the _other_ main loop in sis.c gets it right according to
195 my reading of the code.
197 The bug is: if an interrupt happens when the next instruction
198 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
199 with the current values of PC and NPC, so when the trap returns,
200 the annulled instruction is indeed executed. Another giveaway is
201 that the annul flag is cleared in execute_trap(): the information
202 is demonstrably discarded.
204 The solution is: perform annulling before looking for traps, in
205 fact it's neater to do annulling, see if there's an interrupt and
206 if not, do the instruction, then handle traps be they generated by
207 interrupts pending or by the instruction we might just have done.
208 That's what the sis.c one does.
210 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
212 * sis.h: Add asr17 register for support of SparcLITE (at least the
213 Hitachi ones I find before me)
215 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
216 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
217 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
218 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
219 (init_regs): Initialize y and asr17.
220 NB: In instruction-set space, the Y register is asr0; the
221 instructions have different names for human reasons only.
224 * interf.c: Set boolean mode variable dumbio if invoked with
225 argument "-dumbio" and mention it of verbose.
226 * erc32.c: if "dumbio" is set, do not assume that there is a
227 terminal type device attached to stdin/stdout. Do not set
228 buffering or mess with tcsetattr or do any read operations in
229 order to make UART interrupts; not input data is supported.
230 This is necessary to allow the sim to be used within the eCos
231 testing infrastructure where stdin/stdout are pipes to a TCL
232 program; the sim hangs otherwise.

252 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
254 * interf.c (sim_open): Use revamped memory_read, which makes
255 byte-swapping unnecessary. Add -sparclite-board option for
256 emulating RAM found on typical SPARClite boards. Print
257 error message for unrecognized option.

259 to allow emulation of SPARClite board RAM.
260 (fetch_bytes, store_bytes): New helper functions for revamped
261 mememory_read and memory_write.

267 byte order instead of host byte order.

272 byte-swapping unnecessary.
273 * exec.c (dispatch_instruction): Use revamped memory_read, which

580 Sun Sep 8 14:04:37 1996 Stu Grossman (grossman@critters.cygnus.com)
582 * erc32.c (port_init): Disable this for __GO32__ (got no pty's
585 Mon Aug 12 17:04:58 1996 Stu Grossman (grossman@critters.cygnus.com)
587 * erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't
589 * (port_init): Don't even *try* to open pty's under _WIN32.
590 * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.
591 * float.c: Get rid of #warning. Makes Microsoft C barf.
592 * interf.c (sim_open): Cast fprintf to (fprintf_ftype) to fix
594 * (sim_load sim_create_inferior sim_read): Use prototypes only in
596 * Get rid of enum sim_stop. It's defined in remote-sim.h.
597 * (sim_stop_reason): Define SIGTRAP if _WIN32.
598 * sis.h: Include ansidecl.h and remote-sim.h.
600 Wed Jul 3 16:05:23 1996 Stu Grossman (grossman@critters.cygnus.com)
602 * erc32.c (mec_reset mec_read mec_write memory_read memory_write),
603 sis.h: Get rid of all uses of long long's.
604 * (close_port read_uart write_uart uarta_tx): Don't seg fault
605 when can't open pty's.
606 * exec.c: Add two new instructions: smul, and divscc.
607 * interf.c (flush_windows): New routine to flush the register
608 windows out to the stack just before returning to GDB. Makes
609 backtraces work much better.
611 Wed Jun 26 12:19:11 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
613 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
614 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
615 (docdir, oldincludedir): Removed.
616 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
617 (AC_PROG_INSTALL): Added.
618 * configure: Rebuilt.
620 Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
622 * configure.in: Call AC_PROG_CC before running configure.host.
623 * configure: Rebuild with autoconf 2.10.
625 Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
627 * Makefile.in (install): Don't check to see if tooldir exists.
628 Make $(tooldir) and $(tooldir)/bin.
630 Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
632 * Makefile.in (end.h): Use explicit ./ when running end.
634 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
636 * func.c(bfd_load): Don't try to print the filename if the pfbd is
638 * interf.c(sim_load): Pass the whole string, not just the first
644 * Fixed bug in "go" command.
649 * Fixed bug in interrupt force register (erc32.c).
651 * Change file load function to use bfd_openr.
653 * SIS should now be endian independent.
658 * Fixed FPU timing - some sequences of FPU instructions did not calculate
659 the resource dependencies right.
661 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
662 but no FPU trap is generated.
664 version 1.7.1 31-10-95
667 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
668 the FPU stays in execute mode.
670 * Corrected JMPL and RETT timing (these instructions takes two cycles).
676 * Interrupt during annuled instruction corrupted return address - fixed.
679 version 1.6.2 25-10-95
682 * Added -DFAST_UART to Makefile
685 version 1.6.1 24-10-95
688 * Fixed bug in STDFQ which caused bus error
694 * Modified srt0.s to include code that initiates registers in IU and FPU
695 and initializes the data segment. The simulator 'load' command does not
696 longer initialize the data segment!
698 * Corrected MEC timer operation; scalers now divide the frequency by
701 * MEC breakpoints are not checked during store operation
707 * Fixed some bugs in the cycle counting for IU & FPU instructions.
709 * Fixed bug that allowed an annuled instruction to cause memory exception.
711 * The *ws parameter in mem.c should now contain the number of waitstates
712 required by the memory access (was total number of cycles).
714 * The supplied srt0.s now clears the BSS (thanks Joel).
719 * Added a '-g' switch to enable/disable the GNU readline(), which cause
720 some problems on solaris 2.x machines.
722 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
725 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
730 * Fixed bug in mulscc instruction (how could that ever have worked?)
732 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
737 * Fixed bug in interrupt handling (wrong interrupt selected when more that
738 one interrupt pending)
740 * Fixed updating of condition codes during logical instructions (carry and
741 overflow were not reset)
743 * Fixed bug in WRTBR (tt field was wrongly over-written)
748 * Fixed several bugs in the interrupt handler and callback routines.
