Though I don't see a way around this > split in GDB. Those 5 patches combined should make it possible to read pseudo-registers from the regcache we save for the record target. I say should because I'm still getting some oddities when rebasing my series on top of them and testing the changes, though, so I might be missing something. I also don't really know anything about XSTATE, so if that's also a problem, do let me know! We could also just save xmm and ymmh registers, but I think using ymm is more readable, so I'd prefer to use that if possible. -- Cheers, Guinevere Larsen She/Her/Hers > > Felix > Intel Deutschland GmbH > Registered Address: Am Campeon 10, 85579 Neubiberg, Germany > Tel: +49 89 99 8853-0, www.intel.de > Managing Directors: Sean Fennelly, Jeffrey Schneiderman, Tiffany Doon Silva > Chairperson of the Supervisory Board: Nicole Lau > Registered Office: Munich > Commercial Register: Amtsgericht Muenchen HRB 186928
