- preparation for adding 7800 emulation
cpu (6507) package uncoupled from upstream dependencies
- cpu no longer logs execution of KIL instruction
- randomisation of registers on startup can be handled by the called of
the cpu's Reset() function
- address errors are filtered by an optional IsAddressError() function
in the Memory interface implementation
- Error field removed from execution.Result type
all references to interface{} replaced with any
Log() function takes any type for the detail argument. More convenient
when logging errors or fmt.Stringer types. Logf() function is unaffected
by this change
permissions moved to base logger type. previously only available with
the central logger
the logger.Permission interface indicates whether the environment making
the logging request is allowed to create new log entries. the
environment.Environment type satisifies the Permission interface
logger.Allow is provided as a convienient way of indicating the the log
entry should always be created
added ability to skip tests during a regression run by issuing an
interrupt signal (ctrl-c). two such signals within 250ms will stop the
run completely
corrected log regression. now makes sure log is clear before beginning
collation
