Update to v098r19 release. byuu says: Changelog: - added nall/bit-field.hpp - updated all CPU cores (sans LR35902 due to some complexities) to use BitFields instead of bools - updated as many CPU cores as I could to use BitFields instead of union { struct { uint8_t ... }; }; pairs The speed changes are mostly a wash for this. In some instances, I noticed a ~2-3% speedup (eg SNES emulation), and in others a 2-3% slowdown (eg Famicom emulation.) It's within the margin of error, so it's safe to say it has no impact. This does give us a lot of new useful things, however: - no more manual reconstruction of flag values from lots of left shifts and ORs - no more manual deconstruction of flag values from lots of ANDs - ability to get completely free aliases to flag groups (eg GSU can provide alt2, alt1 and also alt (which is alt2,alt1 combined) - removes the need for the nasty order_lsbN macro hack (eventually will make higan 100% endian independent) - saves us from insane compilers that try and do nasty things with alignment on union-structs - saves us from insane compilers that try to store bit-field bits in reverse order - will allow some really novel new use cases (I'm planning an instant-decode ARM opcode function, for instance.) - reduces code size (we can serialize flag registers in one line instead of one for each flag) However, I probably won't use it for super critical code that's constantly reading out register values (eg PPU MMIO registers.) I think there we would end up with a performance penalty.
