Re: [atlas-devel] gcc 4.7.2 is bad

[M. E. (E. B. <zn...@zn...>]

I just compiled Atlas 3.10.1 with GCC 4.9.2 on my AMD FX(tm)-8350
Eight-Core Processor two days ago. It took about six hours and it had
trouble figuring out the L1 cache size reliably. I'm planning to try
again with the upstream source in a few days; this was recompiling the
source RPM from Fedora 21.
