|

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

Version 2.1 26-02-96
|
|
--------------------
|
|
|
|
* Fixed bug in "go" command.
|
|
|
|
version 2.0 05-02-96
|
|
--------------------
|
|
|
|
* Fixed bug in interrupt force register (erc32.c).
|
|
|
|
* Change file load function to use bfd_openr.
|
|
|
|
* SIS should now be endian independent.
|
|
|
|
version 1.8 24-11-95
|
|
--------------------
|
|
|
|
* Fixed FPU timing - some sequences of FPU instructions did not calculate
|
|
the resource dependencies right.
|
|
|
|
* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
|
|
but no FPU trap is generated.
|
|
|
|
version 1.7.1 31-10-95
|
|
--------------------
|
|
|
|
* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
|
|
the FPU stays in execute mode.
|
|
|
|
* Corrected JMPL and RETT timing (these instructions takes two cycles).
|
|
|
|
|
|
version 1.7 25-10-95
|
|
--------------------
|
|
|
|
* Interrupt during annuled instruction corrupted return address - fixed.
|
|
|
|
|
|
version 1.6.2 25-10-95
|
|
--------------------
|
|
|
|
* Added -DFAST_UART to Makefile
|
|
|
|
|
|
version 1.6.1 24-10-95
|
|
--------------------
|
|
|
|
* Fixed bug in STDFQ which caused bus error
|
|
|
|
|
|
version 1.6 02-10-95
|
|
--------------------
|
|
|
|
* Modified srt0.s to include code that initiates registers in IU and FPU
|
|
and initializes the data segment. The simulator 'load' command does not
|
|
longer initialize the data segment!
|
|
|
|
* Corrected MEC timer operation; scalers now divide the frequency by
|
|
(scaler_value + 1).
|
|
|
|
* MEC breakpoints are not checked during store operation
|
|
|
|
|
|
version 1.5 14-09-95
|
|
--------------------
|
|
|
|
* Fixed some bugs in the cycle counting for IU & FPU instructions.
|
|
|
|
* Fixed bug that allowed an annuled instruction to cause memory exception.
|
|
|
|
* The *ws parameter in mem.c should now contain the number of waitstates
|
|
required by the memory access (was total number of cycles).
|
|
|
|
* The supplied srt0.s now clears the BSS (thanks Joel).
|
|
|
|
version 1.4 22-08-95
|
|
--------------------
|
|
|
|
* Added a '-g' switch to enable/disable the GNU readline(), which cause
|
|
some problems on solaris 2.x machines.
|
|
|
|
* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
|
|
may suffer a bit ...
|
|
|
|
NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
|
|
|
|
version 1.3 26-07-95
|
|
--------------------
|
|
|
|
* Fixed bug in mulscc instruction (how could that ever have worked?)
|
|
|
|
* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
|
|
|
|
version 1.2 13-07-95
|
|
--------------------
|
|
|
|
* Fixed bug in interrupt handling (wrong interrupt selected when more that
|
|
one interrupt pending)
|
|
|
|
* Fixed updating of condition codes during logical instructions (carry and
|
|
overflow were not reset)
|
|
|
|
* Fixed bug in WRTBR (tt field was wrongly over-written)
|
|
|
|
version 1.1 07-07-95
|
|
--------------------
|
|
|
|
* Fixed several bugs in the interrupt handler and callback routines.
