I personally hope to see more 64-bit only processors without the burden of AArch32 support.

- floatboth 6y agoMost server chips with custom cores are like that. Cavium-Marvell ThunderX 1/2 don't support aarch32 at all. Qualcomm Falkor didn't either (RIP).
- repiret 6y agoYou see that in, say, Cortex-A76, which only supports AArch32 at EL0. Supporting AArch32 at EL0 is quite cheap compared to also supporting it at the higher exception levels - EL0 can be done entirely in the instruction decoder.
