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 nullptr) 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_t; 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 *****************************************************************************/ #include "z80.h" #include "../util.h" #include <string.h> #include <stdlib.h> #include <limits.h> #define VERBOSE 0 /* On an NMOS Z80, if LD A,I or LD A,R is interrupted, P/V flag gets reset, even if IFF2 was set before this instruction.
