115 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
117 * exec.c (dispatch_instruction):
118 Correct the sense of the
120 sregs->trap = TRAP_UNIMP;
123 clause that has been pasted around: it's correct in the SCAN and
124 DIVScc (divide step) cases (where it was probably originally
125 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
126 ie. instructions only in the SPARC V8 or SPARClite 86x
127 architectures. It was also present when not required for SMUL,
128 SMULcc, UMUL, UMULcc instructions that are present in all
131 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
133 * interf.c (run_sim): Fix a bug in the main loop's handling of
134 annulled delay slot instructions. There is precedent for this
135 change; the _other_ main loop in sis.c gets it right according to
136 my reading of the code.
138 The bug is: if an interrupt happens when the next instruction
139 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
140 with the current values of PC and NPC, so when the trap returns,
141 the annulled instruction is indeed executed. Another giveaway is
142 that the annul flag is cleared in execute_trap(): the information
143 is demonstrably discarded.
145 The solution is: perform annulling before looking for traps, in
146 fact it's neater to do annulling, see if there's an interrupt and
147 if not, do the instruction, then handle traps be they generated by
148 interrupts pending or by the instruction we might just have done.
149 That's what the sis.c one does.
151 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
153 * sis.h: Add asr17 register for support of SparcLITE (at least the
154 Hitachi ones I find before me)
156 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
157 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
158 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
159 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
160 (init_regs): Initialize y and asr17.
161 NB: In instruction-set space, the Y register is asr0; the
162 instructions have different names for human reasons only.
165 * interf.c: Set boolean mode variable dumbio if invoked with
166 argument "-dumbio" and mention it of verbose.
167 * erc32.c: if "dumbio" is set, do not assume that there is a
168 terminal type device attached to stdin/stdout. Do not set
169 buffering or mess with tcsetattr or do any read operations in
170 order to make UART interrupts; not input data is supported.
171 This is necessary to allow the sim to be used within the eCos
172 testing infrastructure where stdin/stdout are pipes to a TCL
173 program; the sim hangs otherwise.
175 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

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

546 when can't open pty's.
547 * exec.c: Add two new instructions: smul, and divscc.
548 * interf.c (flush_windows): New routine to flush the register
549 windows out to the stack just before returning to GDB. Makes
550 backtraces work much better.
552 Wed Jun 26 12:19:11 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
554 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
555 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
556 (docdir, oldincludedir): Removed.
557 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
558 (AC_PROG_INSTALL): Added.
559 * configure: Rebuilt.
561 Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
563 * configure.in: Call AC_PROG_CC before running configure.host.
564 * configure: Rebuild with autoconf 2.10.
566 Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
568 * Makefile.in (install): Don't check to see if tooldir exists.
569 Make $(tooldir) and $(tooldir)/bin.
571 Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
573 * Makefile.in (end.h): Use explicit ./ when running end.
575 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
577 * func.c(bfd_load): Don't try to print the filename if the pfbd is
579 * interf.c(sim_load): Pass the whole string, not just the first
585 * Fixed bug in "go" command.
590 * Fixed bug in interrupt force register (erc32.c).
592 * Change file load function to use bfd_openr.
594 * SIS should now be endian independent.
599 * Fixed FPU timing - some sequences of FPU instructions did not calculate
600 the resource dependencies right.
602 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
603 but no FPU trap is generated.
605 version 1.7.1 31-10-95
608 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
609 the FPU stays in execute mode.
611 * Corrected JMPL and RETT timing (these instructions takes two cycles).
617 * Interrupt during annuled instruction corrupted return address - fixed.
620 version 1.6.2 25-10-95
623 * Added -DFAST_UART to Makefile
626 version 1.6.1 24-10-95
629 * Fixed bug in STDFQ which caused bus error
635 * Modified srt0.s to include code that initiates registers in IU and FPU
636 and initializes the data segment. The simulator 'load' command does not
637 longer initialize the data segment!
639 * Corrected MEC timer operation; scalers now divide the frequency by
642 * MEC breakpoints are not checked during store operation
648 * Fixed some bugs in the cycle counting for IU & FPU instructions.
650 * Fixed bug that allowed an annuled instruction to cause memory exception.
652 * The *ws parameter in mem.c should now contain the number of waitstates
653 required by the memory access (was total number of cycles).
655 * The supplied srt0.s now clears the BSS (thanks Joel).
660 * Added a '-g' switch to enable/disable the GNU readline(), which cause
661 some problems on solaris 2.x machines.
663 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
666 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
671 * Fixed bug in mulscc instruction (how could that ever have worked?)
673 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
678 * Fixed bug in interrupt handling (wrong interrupt selected when more that
679 one interrupt pending)
681 * Fixed updating of condition codes during logical instructions (carry and
682 overflow were not reset)
684 * Fixed bug in WRTBR (tt field was wrongly over-written)
689 * Fixed several bugs in the interrupt handler and callback routines.
