*
* TODO:
* - If LD A,I or LD A,R is interrupted, P/V flag gets reset, even if IFF2
* was set before this instruction
* - Ideally, the tiny differences between Z80 types should be supported,
* currently known differences:
* - LD A,I/R P/V flag reset glitch is fixed on CMOS Z80
* - OUT (C),0 outputs 0 on NMOS Z80, $FF on CMOS Z80
* - SCF/CCF X/Y flags is ((flags | A) & 0x28) on SGS/SHARP/ZiLOG NMOS Z80,
* (flags & A & 0x28) on NEC NMOS Z80, other models unknown.
* However, people from the Speccy scene mention that SCF/CCF X/Y results
* are inconsistant and may be influenced by I and R registers.
* This Z80 emulator assumes a ZiLOG NMOS model.
*
* Additional changes [Eke-Eke]:
* - Removed z80_burn function (unused)
* - Discarded multi-chip support (unused)
* - Fixed cycle counting for FD and DD prefixed instructions
* - Fixed behavior of chained FD and DD prefixes (R register should be only incremented by one
* - Implemented cycle-accurate INI/IND (needed by SMS emulation)
* - Fixed Z80 reset
* - Made SZHVC_add & SZHVC_sub tables statically allocated
* - Fixed compiler warning when BIG_SWITCH is defined
* Changes in 3.9:
* - Fixed cycle counts for LD IYL/IXL/IYH/IXH,n [Marshmellow]
* - Fixed X/Y flags in CCF/SCF/BIT, ZEXALL is happy now [hap]
* - Simplified DAA, renamed MEMPTR (3.8) to WZ, added TODO [hap]
* - Fixed IM2 interrupt cycles [eke]
* Changes in 3.8 [Miodrag Milanovic]:
* - Added MEMPTR register (according to informations provided
* by Vladimir Kladov
* - BIT n,(HL) now return valid values due to use of MEMPTR
* - Fixed BIT 6,(XY+o) undocumented instructions
* Changes in 3.7 [Aaron Giles]:
* - Changed NMI handling. NMIs are now latched in set_irq_state
* but are not taken there. Instead they are taken at the start of the
* execute loop.
* - Changed IRQ handling. IRQ state is set in set_irq_state but not taken
* except during the inner execute loop.
* - Removed x86 assembly hacks and obsolete timing loop catchers.
* Changes in 3.6:
* - Got rid of the code that would inexactly emulate a Z80, i.e. removed
* all the #if Z80_EXACT #else branches.
* - Removed leading underscores from local register name shortcuts as
* this violates the C99 standard.
* - Renamed the registers inside the Z80 context to lower case to avoid
* ambiguities (shortcuts would have had the same names as the fields
* of the structure).
* Changes in 3.5:
* - Implemented OTIR, INIR, etc. without look-up table for PF flag.
* [Ramsoft, Sean Young]
* Changes in 3.4:
* - Removed Z80-MSX specific code as it's not needed any more.
* - Implemented DAA without look-up table [Ramsoft, Sean Young]
* Changes in 3.3:
* - Fixed undocumented flags XF & YF in the non-asm versions of CP,
* and all the 16 bit arithmetic instructions. [Sean Young]
* Changes in 3.2:
* - Fixed undocumented flags XF & YF of RRCA, and CF and HF of
* INI/IND/OUTI/OUTD/INIR/INDR/OTIR/OTDR [Sean Young]
* Changes in 3.1:
* - removed the REPEAT_AT_ONCE execution of LDIR/CPIR etc. opcodes
* for readabilities sake and because the implementation was buggy
* (and I was not able to find the difference)
* Changes in 3.0:
* - 'finished' switch to dynamically overrideable cycle count tables
* Changes in 2.9:
* - added methods to access and override the cycle count tables
* - fixed handling and timing of multiple DD/FD prefixed opcodes
* Changes in 2.8:
* - OUTI/OUTD/OTIR/OTDR also pre-decrement the B register now.
* This was wrong because of a bug fix on the wrong side
* (astrocade sound driver).
* Changes in 2.7:
* - removed z80_vm specific code, it's not needed (and never was).
* Changes in 2.6:
* - BUSY_LOOP_HACKS needed to call change_pc() earlier, before
* checking the opcodes at the new address, because otherwise they
* might access the old (wrong or even NULL) banked memory region.
* Thanks to Sean Young for finding this nasty bug.
* Changes in 2.5:
* - Burning cycles always adjusts the ICount by a multiple of 4.
* - In REPEAT_AT_ONCE cases the R register wasn't incremented twice
* per repetition as it should have been. Those repeated opcodes
* could also underflow the ICount.
* - Simplified TIME_LOOP_HACKS for BC and added two more for DE + HL
* timing loops. I think those hacks weren't endian safe before too.
* Changes in 2.4:
* - z80_reset zaps the entire context, sets IX and IY to 0xffff(!) and
* sets the Z flag. With these changes the Tehkan World Cup driver
* _seems_ to work again.
* Changes in 2.3:
* - External termination of the execution loop calls z80_burn() and
* z80_vm_burn() to burn an amount of cycles (R adjustment)
* - Shortcuts which burn CPU cycles (BUSY_LOOP_HACKS and TIME_LOOP_HACKS)
* now also adjust the R register depending on the skipped opcodes.
* Changes in 2.2:
* - Fixed bugs in CPL, SCF and CCF instructions flag handling.
* - Changed variable EA and ARG16() function to UINT32; this
* produces slightly more efficient code.
* - The DD/FD XY CB opcodes where XY is 40-7F and Y is not 6/E
* are changed to calls to the X6/XE opcodes to reduce object size.
* They're hardly ever used so this should not yield a speed penalty.
* New in 2.0:
* - Optional more exact Z80 emulation (#define Z80_EXACT 1) according
* to a detailed description by Sean Young which can be found at:
* http://www.msxnet.org/tech/z80-documented.pdf
