Hi Ed,

Are you talking about FP registers being allocated for integer values
such that you dont know if FP registers are used in integer application
and you have to b
Why don't you just have Boost.Context be a wrapper around
getcontext/setcontext/swapcontext and ignore the save_fp argument? Then you
don't need to write anything special for AARCH64 or any new target?
Thanks,
