Thanks, I missed that. It's annoying that we'll end up needing /both/ -ffixed-x18 *and* the save/restore around guest transitions, but if we actually want to use SCS for the VHE code then I see that it will be required. Sami -- can you restore -ffixed-x18 and then try the function attribute as suggested by James, please?
Sure. Adding __noscs to __hyp_text and not filtering out any of the flags in the Makefile appears to work. I'll update this in the next version.
