Please give details of what the entries would be for <https://sourceware.org/glibc/wiki/ABIList> and <https://sourceware.org/glibc/wiki/PortStatus> for this port that you intend to add once the port is in.

Last time I checked, static-pie doesn't work for ARC either ATM. There's nothing else ARC specific, which needs calling out there.

Are you waiting for me to fold the 64-bit time stuff and a respin for a more in depth review of the patchset. I appreciate you have a zillion other things backed up on your todo list :-) Let me know how to proceed. Thx, -Vineet

I've addressed all the review comments on v3 and posted a v4 [1]. Can you please take a look when you get chance.

Hi, This patchset implements glibc port to ARC HS48x processor from Synopsys. It is based on 64-time time and offset work by Alistair and others. Thank you guys for all the hard-work.
