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 https://www.sevarg.net/2019/12/10/being-sick-sucks/

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.
