99 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
101 * exec.c (dispatch_instruction):
102 Correct the sense of the
104 sregs->trap = TRAP_UNIMP;
107 clause that has been pasted around: it's correct in the SCAN and
108 DIVScc (divide step) cases (where it was probably originally
109 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
110 ie. instructions only in the SPARC V8 or SPARClite 86x
111 architectures. It was also present when not required for SMUL,
112 SMULcc, UMUL, UMULcc instructions that are present in all
115 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
117 * interf.c (run_sim): Fix a bug in the main loop's handling of
118 annulled delay slot instructions. There is precedent for this
119 change; the _other_ main loop in sis.c gets it right according to
120 my reading of the code.
122 The bug is: if an interrupt happens when the next instruction
123 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
124 with the current values of PC and NPC, so when the trap returns,
125 the annulled instruction is indeed executed. Another giveaway is
126 that the annul flag is cleared in execute_trap(): the information
127 is demonstrably discarded.
129 The solution is: perform annulling before looking for traps, in
130 fact it's neater to do annulling, see if there's an interrupt and
131 if not, do the instruction, then handle traps be they generated by
132 interrupts pending or by the instruction we might just have done.
133 That's what the sis.c one does.
135 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
137 * sis.h: Add asr17 register for support of SparcLITE (at least the
138 Hitachi ones I find before me)
140 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
141 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
142 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
143 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
144 (init_regs): Initialize y and asr17.
145 NB: In instruction-set space, the Y register is asr0; the
146 instructions have different names for human reasons only.
149 * interf.c: Set boolean mode variable dumbio if invoked with
150 argument "-dumbio" and mention it of verbose.
151 * erc32.c: if "dumbio" is set, do not assume that there is a
152 terminal type device attached to stdin/stdout. Do not set
153 buffering or mess with tcsetattr or do any read operations in
154 order to make UART interrupts; not input data is supported.
155 This is necessary to allow the sim to be used within the eCos
156 testing infrastructure where stdin/stdout are pipes to a TCL
157 program; the sim hangs otherwise.
159 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

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

184 to allow emulation of SPARClite board RAM.
185 (fetch_bytes, store_bytes): New helper functions for revamped
186 mememory_read and memory_write.

188 byte order instead of storing words in host byte order; this
189 greatly simplifies support of little-endian programs.
190 (get_mem_ptr): Remove unnecessary byte parameter.
191 (sis_memory_write, sis_memory_read): Store words in target
192 byte order instead of host byte order.
193 (byte_swap_words): Remove, no longer needed.
194 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
195 (memory_read): Add new sz parameter.
196 * sis.c (run_sim): Use revamped memory_read, which makes
197 byte-swapping unnecessary.
198 * exec.c (dispatch_instruction): Use revamped memory_read, which
199 makes byte-swapping and double-word fetching unnecessary.

541 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
542 (AC_PROG_INSTALL): Added.
543 * configure: Rebuilt.
545 Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
547 * configure.in: Call AC_PROG_CC before running configure.host.
548 * configure: Rebuild with autoconf 2.10.
550 Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
552 * Makefile.in (install): Don't check to see if tooldir exists.
553 Make $(tooldir) and $(tooldir)/bin.
555 Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
557 * Makefile.in (end.h): Use explicit ./ when running end.
559 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
561 * func.c(bfd_load): Don't try to print the filename if the pfbd is
563 * interf.c(sim_load): Pass the whole string, not just the first
569 * Fixed bug in "go" command.
574 * Fixed bug in interrupt force register (erc32.c).
576 * Change file load function to use bfd_openr.
578 * SIS should now be endian independent.
583 * Fixed FPU timing - some sequences of FPU instructions did not calculate
584 the resource dependencies right.
586 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
587 but no FPU trap is generated.
589 version 1.7.1 31-10-95
592 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
593 the FPU stays in execute mode.
595 * Corrected JMPL and RETT timing (these instructions takes two cycles).
601 * Interrupt during annuled instruction corrupted return address - fixed.
604 version 1.6.2 25-10-95
607 * Added -DFAST_UART to Makefile
610 version 1.6.1 24-10-95
613 * Fixed bug in STDFQ which caused bus error
619 * Modified srt0.s to include code that initiates registers in IU and FPU
620 and initializes the data segment. The simulator 'load' command does not
621 longer initialize the data segment!
623 * Corrected MEC timer operation; scalers now divide the frequency by
626 * MEC breakpoints are not checked during store operation
632 * Fixed some bugs in the cycle counting for IU & FPU instructions.
634 * Fixed bug that allowed an annuled instruction to cause memory exception.
636 * The *ws parameter in mem.c should now contain the number of waitstates
637 required by the memory access (was total number of cycles).
639 * The supplied srt0.s now clears the BSS (thanks Joel).
644 * Added a '-g' switch to enable/disable the GNU readline(), which cause
645 some problems on solaris 2.x machines.
647 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
650 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
655 * Fixed bug in mulscc instruction (how could that ever have worked?)
657 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
662 * Fixed bug in interrupt handling (wrong interrupt selected when more that
663 one interrupt pending)
665 * Fixed updating of condition codes during logical instructions (carry and
666 overflow were not reset)
668 * Fixed bug in WRTBR (tt field was wrongly over-written)
673 * Fixed several bugs in the interrupt handler and callback routines.
