TBH, I have yet to see one which lacks CF.

Out of the top of my head, mips, Alpha, AM29000. There are plenty more.

Head? you mean wikipedia? :)
From https://en.wikipedia.org/wiki/Status_register#CPU_architectu... those architectures put the carry result in a general-purpose register, but you still can't access the result in C.

They were the three architectures that immediately sprung to mind when I though of cpus without carry bits. I have only programmed in assembly for two of them -- I might well have read that wiki page before.
