Hi Petr!
Long time, no see :-) Looks like you just can't stop from doing amazing
stuff, do you? :-D It will be great to have the arm64 port upstreamed!
When you do that, I have an additional request: You know all the AArch64
documents, can you add links, or at least names to http://www.helenos.org/
wiki/DeveloperDocs/CPUArch ? I managed to identify one, the A64 instruction
set.
Do you know the name/link especially for the System V ABI processor
supplement for AArch64? Do you know if there is a document describing TLS
support for AArch64 so we can implement Dynamic linking+TLS support? (or is
that part of the ABI CPU supplement?)
Cheers,
Jiri

This is simply amazing! I briefly glanced through your changes, built
the toolchain and ran HelenOS/arm64. Truly a wonderful achievement!
Indeed, we would be interested in having this upstreamed to HelenOS. I'd
suggest rebasing to the current master and then submitting a PR.
Thanks!
Jakub
