atlas: add gcc6 variant.

Port: atlas


atlas currently does not have a gcc6 variant.

As I was rebuilding my MacPorts under Sierra, I wanted to build octave with the atlas variant, using the same gcc6 compiler for atlas as for octave.

Version: 2.3.4

Can this port be switched to use the compilers portgroup?

Atlas needs a complete overhaul. The 3.10.3 version is out.

But the major problem is this: ‘atlas’ requires the CPU to run at full speed to properly measure performance. But MacOS 10.11+ apparently won’t let it do that: it automatically inserts idle cycles to keep the CPU cool when it detects the temperature rises too fast. That will thwart any attempt to derive meaningful measures.

I'll have first to figure out a way to de-activate that behaviour. I think I’ve stumbled on something trawling through the Internet, but it’ll take a bit of time to figure out how to piece everything together.

Any news?

Never mind that lapack is now at version 3.7.0.
