59 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
61 * exec.c (dispatch_instruction):
62 Correct the sense of the
64 sregs->trap = TRAP_UNIMP;
67 clause that has been pasted around: it's correct in the SCAN and
68 DIVScc (divide step) cases (where it was probably originally
69 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
70 ie. instructions only in the SPARC V8 or SPARClite 86x
71 architectures. It was also present when not required for SMUL,
72 SMULcc, UMUL, UMULcc instructions that are present in all
75 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
77 * interf.c (run_sim): Fix a bug in the main loop's handling of
78 annulled delay slot instructions. There is precedent for this
79 change; the _other_ main loop in sis.c gets it right according to
80 my reading of the code.
82 The bug is: if an interrupt happens when the next instruction
83 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
84 with the current values of PC and NPC, so when the trap returns,
85 the annulled instruction is indeed executed. Another giveaway is
86 that the annul flag is cleared in execute_trap(): the information
87 is demonstrably discarded.
89 The solution is: perform annulling before looking for traps, in
90 fact it's neater to do annulling, see if there's an interrupt and
91 if not, do the instruction, then handle traps be they generated by
92 interrupts pending or by the instruction we might just have done.
93 That's what the sis.c one does.
95 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
97 * sis.h: Add asr17 register for support of SparcLITE (at least the
98 Hitachi ones I find before me)
100 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
101 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
102 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
103 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
104 (init_regs): Initialize y and asr17.
105 NB: In instruction-set space, the Y register is asr0; the
106 instructions have different names for human reasons only.
109 * interf.c: Set boolean mode variable dumbio if invoked with
110 argument "-dumbio" and mention it of verbose.
111 * erc32.c: if "dumbio" is set, do not assume that there is a
112 terminal type device attached to stdin/stdout. Do not set
113 buffering or mess with tcsetattr or do any read operations in
114 order to make UART interrupts; not input data is supported.
115 This is necessary to allow the sim to be used within the eCos
116 testing infrastructure where stdin/stdout are pipes to a TCL
117 program; the sim hangs otherwise.
119 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

137 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
139 * interf.c (sim_open): Use revamped memory_read, which makes
140 byte-swapping unnecessary. Add -sparclite-board option for
141 emulating RAM found on typical SPARClite boards. Print
142 error message for unrecognized option.
143 * erc32.c: Change RAM address and size from constants to variables,
144 to allow emulation of SPARClite board RAM.
145 (fetch_bytes, store_bytes): New helper functions for revamped
146 mememory_read and memory_write.
147 (memory_read, memory_write): Rewrite to store bytes in target
148 byte order instead of storing words in host byte order; this
149 greatly simplifies support of little-endian programs.

151 (sis_memory_write, sis_memory_read): Store words in target
152 byte order instead of host byte order.
153 (byte_swap_words): Remove, no longer needed.
154 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
155 (memory_read): Add new sz parameter.
156 * sis.c (run_sim): Use revamped memory_read, which makes
157 byte-swapping unnecessary.
158 * exec.c (dispatch_instruction): Use revamped memory_read, which
159 makes byte-swapping and double-word fetching unnecessary.
160 * func.c (sparclite_board): Declare new variable.

552 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
553 the FPU stays in execute mode.
555 * Corrected JMPL and RETT timing (these instructions takes two cycles).
561 * Interrupt during annuled instruction corrupted return address - fixed.
564 version 1.6.2 25-10-95
567 * Added -DFAST_UART to Makefile
570 version 1.6.1 24-10-95
573 * Fixed bug in STDFQ which caused bus error
579 * Modified srt0.s to include code that initiates registers in IU and FPU
580 and initializes the data segment. The simulator 'load' command does not
581 longer initialize the data segment!
583 * Corrected MEC timer operation; scalers now divide the frequency by
586 * MEC breakpoints are not checked during store operation
592 * Fixed some bugs in the cycle counting for IU & FPU instructions.
594 * Fixed bug that allowed an annuled instruction to cause memory exception.
596 * The *ws parameter in mem.c should now contain the number of waitstates
597 required by the memory access (was total number of cycles).
599 * The supplied srt0.s now clears the BSS (thanks Joel).
604 * Added a '-g' switch to enable/disable the GNU readline(), which cause
605 some problems on solaris 2.x machines.
607 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
610 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
615 * Fixed bug in mulscc instruction (how could that ever have worked?)
617 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
622 * Fixed bug in interrupt handling (wrong interrupt selected when more that
623 one interrupt pending)
625 * Fixed updating of condition codes during logical instructions (carry and
626 overflow were not reset)
628 * Fixed bug in WRTBR (tt field was wrongly over-written)
633 * Fixed several bugs in the interrupt handler and callback routines.
