If you can provide -mlra vs. -mno-lra testsuite results as well that would be interesting. Does "just work" mean you can build the compiler and its target libraries? In this case I would suggest to go further and pull the trigger now, defaulting to LRA but allowing to switch back to reload for testing. This is so the few people testing alpha at all can increase testing coverage - I don't think anybody runs older than EV5 HW. Is VMS on alpha still a thing btw? I still see it mentioned in config.gcc Richard. > Adrian > > -- > .''`.
