Can you provide an example of how this can be done? The whole point of this report is to show that what you claim isn't actually possible. If it is possible, then that'd be a great thing -- but someone shoould update the docs to show that it is possible. Here's a wacky idea -- update the constraints system for the x86_64 target to allow any available (and specific) register to be constrained. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38925
