Being sick sucks.

So if you’re wondering about Saturday’s missing post, that’s why.

I’ve been sick the past few days (and I basically hibernate when sick), and the kids have been varying degrees of sick as well - which isn’t fun either.

This is a companion discussion topic for the original entry at

Hope you are feeling better. As to 64 bit, in most (all?) cases more registers are available,
the compiler will use them automatically. For aarch64 IIRR it is only 2 extra, for x86 maybe 4
So, if the job is cpu limited and the extra registers will make a difference…?
And, of course, with more than 4G mem, flat is easier than paged, this does not seem common

ARMv8 doubles the registers vs ARMv7 - 32 vs 16. x86-64 similarly adds another 8 registers and a few nice addressing modes.
