This is probably completely and utterly wrong as it's just a guess, but potentially the Thumb [1] instructions (small, limited subset of shorter instructions in ARM) might allow for a wider setup. Thumb instructions make a bunch of simplifying assumptions that might remove some of the issues with going wider. Not that I have any idea if Cyclone even supports them in the first place.

- wtallis 13y agoThe biggest wart on the ARM instruction set was the predicate attached to basically every instruction. That's gone in the 64-bit ARM ISA, so there's no need for a 64-bit Thumb (and there isn't one).
