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

164 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
166 * interf.c (sim_open): Use revamped memory_read, which makes
167 byte-swapping unnecessary. Add -sparclite-board option for
168 emulating RAM found on typical SPARClite boards. Print
169 error message for unrecognized option.
170 * erc32.c: Change RAM address and size from constants to variables,
171 to allow emulation of SPARClite board RAM.
172 (fetch_bytes, store_bytes): New helper functions for revamped
173 mememory_read and memory_write.
174 (memory_read, memory_write): Rewrite to store bytes in target
175 byte order instead of storing words in host byte order; this
176 greatly simplifies support of little-endian programs.
177 (get_mem_ptr): Remove unnecessary byte parameter.
178 (sis_memory_write, sis_memory_read): Store words in target
179 byte order instead of host byte order.
180 (byte_swap_words): Remove, no longer needed.
181 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
182 (memory_read): Add new sz parameter.
183 * sis.c (run_sim): Use revamped memory_read, which makes
184 byte-swapping unnecessary.
185 * exec.c (dispatch_instruction): Use revamped memory_read, which
186 makes byte-swapping and double-word fetching unnecessary.
187 * func.c (sparclite_board): Declare new variable.
188 (get_regi): Handle little-endian data.
189 (bfd_load): Recognize little-endian SPARClite as having

212 * interf.c (run_sim): Always fetch instructions as big-endian.

539 * Makefile.in (install): Don't check to see if tooldir exists.
540 Make $(tooldir) and $(tooldir)/bin.
542 Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
544 * Makefile.in (end.h): Use explicit ./ when running end.
546 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
548 * func.c(bfd_load): Don't try to print the filename if the pfbd is
550 * interf.c(sim_load): Pass the whole string, not just the first
556 * Fixed bug in "go" command.
561 * Fixed bug in interrupt force register (erc32.c).
563 * Change file load function to use bfd_openr.
565 * SIS should now be endian independent.
570 * Fixed FPU timing - some sequences of FPU instructions did not calculate
571 the resource dependencies right.
573 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
574 but no FPU trap is generated.
576 version 1.7.1 31-10-95
579 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
580 the FPU stays in execute mode.
582 * Corrected JMPL and RETT timing (these instructions takes two cycles).
588 * Interrupt during annuled instruction corrupted return address - fixed.
591 version 1.6.2 25-10-95
594 * Added -DFAST_UART to Makefile
597 version 1.6.1 24-10-95
600 * Fixed bug in STDFQ which caused bus error
606 * Modified srt0.s to include code that initiates registers in IU and FPU
607 and initializes the data segment. The simulator 'load' command does not
608 longer initialize the data segment!
610 * Corrected MEC timer operation; scalers now divide the frequency by
613 * MEC breakpoints are not checked during store operation
619 * Fixed some bugs in the cycle counting for IU & FPU instructions.
621 * Fixed bug that allowed an annuled instruction to cause memory exception.
623 * The *ws parameter in mem.c should now contain the number of waitstates
624 required by the memory access (was total number of cycles).
626 * The supplied srt0.s now clears the BSS (thanks Joel).
631 * Added a '-g' switch to enable/disable the GNU readline(), which cause
632 some problems on solaris 2.x machines.
634 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
637 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
642 * Fixed bug in mulscc instruction (how could that ever have worked?)
644 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
649 * Fixed bug in interrupt handling (wrong interrupt selected when more that
650 one interrupt pending)
652 * Fixed updating of condition codes during logical instructions (carry and
653 overflow were not reset)
655 * Fixed bug in WRTBR (tt field was wrongly over-written)
660 * Fixed several bugs in the interrupt handler and callback routines.
