LLVM SEH docs -- enregistration of locals in nonvolatile registers?
...with the nonvolatiles restored. Obviously cumbersome to access, but it lets you enregister them across calls like normal in the "original" function.
I haven't seen Visual C++ to such enregistration (nonvolatiles across calls in functions with EH), but you can do it in assembly.
nvlocala.asm here http://jaykrell2.blogspot.com/2017/10/windows-amd64-abi-nuances-part-1.html
I should change it to print the nonvolatiles from context to demonstrate the point.
