Let's try to stick with facts, not speculation. And the test case is not generated, it is the Eigen template library applied to mpfr. I've put a lot of hard work into it to fix almost all scalability problems on this PR for gcc 4.8. LRA undoes all of that work. I understand it is painful for some people to hear, but I remain of opinion that LRA cannot be considered "ready" if it scales so much worse than everything else in the compiler. Ciao! Steven
