rr is basically black magic

It's a real shame that it can't be made to work on arm systems

[natrys]

Readme and latest release note says it now supports Neoverse N1 (ampere altra, graviton2 and maybe some cortex ones) as well as Apple M1.

Wow! That's amazing, i thought there were architectural issues that prevented it (something about interrupt timings sometimes increasing the number of instructions non-deterministically iirc).

Will have to check that out!

[mijoharas]

There it is!

AFAIK it works on AWS graviton.

[guipsp]

It does seem to work on Apple ARM

Does it? Or is it running in Rosetta?

[hobofan]

AFAIK it only works on Linux on bare metal M1 (so not on virtualized Linux in macOS).
