OPCODE_MEMSET with zva
* Add unit tests * Use `dc zva` to zero out entire cache-lines worth of data, when possible * Special instruction that zaps an entire cache-line into being zero-values, typically 64-bytes at a time * Statically read and initialize the `DCZID_EL0` register value since reading registers with `mrs` can be kinda slow and isn't worth doing redundantly at JIT-time when it never changes. * Update store-instructions to use inline post-increments to avoid an additional `add` instruction and keep encoded instruction immediates small Pretty much every arm processor has a cache line size of 64 bytes, so a typical `dcbz128` to clear 128-bytes of data now results in: ``` dc zva, x0 add x0, x0, 64 dc zva, x0 ``` rather than a sequence of 8 `stp xzr, xzr, ...` instructions
Xenia Canary - Xbox 360 Emulator
Xenia Canary is an experimental fork of the Xenia emulator. For more information, see the Xenia Canary wiki.
Come chat with us about emulator-related topics on Discord.
For developer chat join #dev but stay on topic. Lurking is not only fine, but encouraged!

Contributors Wanted!
Have some spare time, know advanced C++, and want to write an emulator? Contribute! There's a ton of work that needs to be done, a lot of which is wide open greenfield fun.
For general rules and guidelines please see CONTRIBUTING.md.
Fixes and optimizations are always welcome (please!), but in addition to that there are some major work areas still untouched:
- Help work through missing functionality/bugs in games
- Reduce the size of Xenia's huge log files
- Skilled with Linux? A strong contributor is needed to help with porting
See more projects good for contributors. It's a good idea to ask on Discord and check the issues page before beginning work on something.
