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

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

270 to allow emulation of SPARClite board RAM.
271 (fetch_bytes, store_bytes): New helper functions for revamped
272 mememory_read and memory_write.

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

280 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
281 (memory_read): Add new sz parameter.
282 * sis.c (run_sim): Use revamped memory_read, which makes
283 byte-swapping unnecessary.
284 * exec.c (dispatch_instruction): Use revamped memory_read, which

600 * (port_init): Don't even *try* to open pty's under _WIN32.
601 * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.
602 * float.c: Get rid of #warning. Makes Microsoft C barf.
603 * interf.c (sim_open): Cast fprintf to (fprintf_ftype) to fix

616 when can't open pty's.
617 * exec.c: Add two new instructions: smul, and divscc.
618 * interf.c (flush_windows): New routine to flush the register
619 windows out to the stack just before returning to GDB. Makes
620 backtraces work much better.
622 Wed Jun 26 12:19:11 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
624 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
625 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
626 (docdir, oldincludedir): Removed.
627 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
628 (AC_PROG_INSTALL): Added.
629 * configure: Rebuilt.
631 Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
633 * configure.in: Call AC_PROG_CC before running configure.host.
634 * configure: Rebuild with autoconf 2.10.
636 Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
638 * Makefile.in (install): Don't check to see if tooldir exists.
639 Make $(tooldir) and $(tooldir)/bin.
641 Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
643 * Makefile.in (end.h): Use explicit ./ when running end.
645 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
647 * func.c(bfd_load): Don't try to print the filename if the pfbd is
649 * interf.c(sim_load): Pass the whole string, not just the first
655 * Fixed bug in "go" command.
660 * Fixed bug in interrupt force register (erc32.c).
662 * Change file load function to use bfd_openr.
664 * SIS should now be endian independent.
669 * Fixed FPU timing - some sequences of FPU instructions did not calculate
670 the resource dependencies right.
672 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
673 but no FPU trap is generated.
675 version 1.7.1 31-10-95
678 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
679 the FPU stays in execute mode.
681 * Corrected JMPL and RETT timing (these instructions takes two cycles).
687 * Interrupt during annuled instruction corrupted return address - fixed.
690 version 1.6.2 25-10-95
693 * Added -DFAST_UART to Makefile
696 version 1.6.1 24-10-95
699 * Fixed bug in STDFQ which caused bus error
705 * Modified srt0.s to include code that initiates registers in IU and FPU
706 and initializes the data segment. The simulator 'load' command does not
707 longer initialize the data segment!
709 * Corrected MEC timer operation; scalers now divide the frequency by
712 * MEC breakpoints are not checked during store operation
718 * Fixed some bugs in the cycle counting for IU & FPU instructions.
720 * Fixed bug that allowed an annuled instruction to cause memory exception.
722 * The *ws parameter in mem.c should now contain the number of waitstates
723 required by the memory access (was total number of cycles).
725 * The supplied srt0.s now clears the BSS (thanks Joel).
730 * Added a '-g' switch to enable/disable the GNU readline(), which cause
731 some problems on solaris 2.x machines.
733 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
736 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
741 * Fixed bug in mulscc instruction (how could that ever have worked?)
743 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
748 * Fixed bug in interrupt handling (wrong interrupt selected when more that
749 one interrupt pending)
751 * Fixed updating of condition codes during logical instructions (carry and
752 overflow were not reset)
754 * Fixed bug in WRTBR (tt field was wrongly over-written)
759 * Fixed several bugs in the interrupt handler and callback routines.
