Version 1.10.0

• Abolish FP functions (NOTE: Destructive change)
  • Eliminate FP methods that register callback functions as explicit function pointers
  • In principle, std::function should be used
  • If you defined -DZ80_NO_FUNCTIONAL, std::function should not be used, and use function pointer explicity.
    • This is a remedy for the unavailability of std::function in the Baremetal environment of the RaspberryPi, etc.
    • Alternatively, it may be desirable to define this in an environment with severe performance constraints.
• Added compile option -DZ80_NO_EXCEPTION to not throw exceptions
• Add wtc.fetchM and clock test case for MSX
• Add compile flags for performance:
  • Z80_CALLBACK_WITHOUT_CHECK ... Omit the check process when calling consumeClock callback
  • Z80_CALLBACK_PER_INSTRUCTION ... Calls consumeClock callback on an instruction-by-instruction basis (NOTE: two or more instructions when interrupting)
  • Z80_UNSUPPORT_16BIT_PORT ... Reduces extra branches by always assuming the port number to be 8 bits
• optimize checkConditionFlag (do not use branch)
• optimize rotate instructions
• optimize flag set/reset
