148 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
150 * exec.c (dispatch_instruction):
151 Correct the sense of the
153 sregs->trap = TRAP_UNIMP;
156 clause that has been pasted around: it's correct in the SCAN and
157 DIVScc (divide step) cases (where it was probably originally
158 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
159 ie. instructions only in the SPARC V8 or SPARClite 86x
160 architectures. It was also present when not required for SMUL,
161 SMULcc, UMUL, UMULcc instructions that are present in all
164 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
166 * interf.c (run_sim): Fix a bug in the main loop's handling of
167 annulled delay slot instructions. There is precedent for this
168 change; the _other_ main loop in sis.c gets it right according to
169 my reading of the code.
171 The bug is: if an interrupt happens when the next instruction
172 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
173 with the current values of PC and NPC, so when the trap returns,
174 the annulled instruction is indeed executed. Another giveaway is
175 that the annul flag is cleared in execute_trap(): the information
176 is demonstrably discarded.
178 The solution is: perform annulling before looking for traps, in
179 fact it's neater to do annulling, see if there's an interrupt and
180 if not, do the instruction, then handle traps be they generated by
181 interrupts pending or by the instruction we might just have done.
182 That's what the sis.c one does.
184 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
186 * sis.h: Add asr17 register for support of SparcLITE (at least the
187 Hitachi ones I find before me)
189 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
190 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
191 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
192 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
193 (init_regs): Initialize y and asr17.
194 NB: In instruction-set space, the Y register is asr0; the
195 instructions have different names for human reasons only.
198 * interf.c: Set boolean mode variable dumbio if invoked with
199 argument "-dumbio" and mention it of verbose.
200 * erc32.c: if "dumbio" is set, do not assume that there is a
201 terminal type device attached to stdin/stdout. Do not set
202 buffering or mess with tcsetattr or do any read operations in
203 order to make UART interrupts; not input data is supported.
204 This is necessary to allow the sim to be used within the eCos
205 testing infrastructure where stdin/stdout are pipes to a TCL
206 program; the sim hangs otherwise.
208 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

226 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
228 * interf.c (sim_open): Use revamped memory_read, which makes
229 byte-swapping unnecessary. Add -sparclite-board option for
230 emulating RAM found on typical SPARClite boards. Print
231 error message for unrecognized option.
232 * erc32.c: Change RAM address and size from constants to variables,
233 to allow emulation of SPARClite board RAM.
234 (fetch_bytes, store_bytes): New helper functions for revamped
235 mememory_read and memory_write.
236 (memory_read, memory_write): Rewrite to store bytes in target
237 byte order instead of storing words in host byte order; this
238 greatly simplifies support of little-endian programs.

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

243 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
244 (memory_read): Add new sz parameter.
245 * sis.c (run_sim): Use revamped memory_read, which makes
246 byte-swapping unnecessary.
247 * exec.c (dispatch_instruction): Use revamped memory_read, which
248 makes byte-swapping and double-word fetching unnecessary.

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