411 but no FPU trap is generated.
413 version 1.7.1 31-10-95
416 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
417 the FPU stays in execute mode.
419 * Corrected JMPL and RETT timing (these instructions takes two cycles).
425 * Interrupt during annuled instruction corrupted return address - fixed.
428 version 1.6.2 25-10-95

437 * Fixed bug in STDFQ which caused bus error
443 * Modified srt0.s to include code that initiates registers in IU and FPU
444 and initializes the data segment. The simulator 'load' command does not
445 longer initialize the data segment!
447 * Corrected MEC timer operation; scalers now divide the frequency by
450 * MEC breakpoints are not checked during store operation
456 * Fixed some bugs in the cycle counting for IU & FPU instructions.
458 * Fixed bug that allowed an annuled instruction to cause memory exception.
460 * The *ws parameter in mem.c should now contain the number of waitstates
461 required by the memory access (was total number of cycles).
463 * The supplied srt0.s now clears the BSS (thanks Joel).
468 * Added a '-g' switch to enable/disable the GNU readline(), which cause
469 some problems on solaris 2.x machines.
471 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
474 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
479 * Fixed bug in mulscc instruction (how could that ever have worked?)
481 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
486 * Fixed bug in interrupt handling (wrong interrupt selected when more that
487 one interrupt pending)
489 * Fixed updating of condition codes during logical instructions (carry and
490 overflow were not reset)
492 * Fixed bug in WRTBR (tt field was wrongly over-written)
497 * Fixed several bugs in the interrupt handler and callback routines.
498 (reported by Paul Warren, Alsys)
