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.
