Jesus. I built a new test system for the CPU core of my iOS emulator and out of 180 instruction classes, only 10 of them are passing all their tests. How the hell does this emulator WORK AT ALL?!
Is this 32-bit ARM or AArch64? Or both? I would think AArch64, being more RISC-ish, has fewer weird quirks (like no conditional prefixes, etc.) but that may be totally wrong…

Just AArch64, and there are definitely *far* fewer weird quirks than <=ARMv7, but especially with the vector instructions there are still a ton of quirks. Thankfully, I can ignore a great many of them just due to what I'm using it for.
