[PATCH 0/3] coccinelle: add parallel execution

From: Greg Dietsche
Date: Tue Jul 12 2011 - 21:25:34 EST


This patch series adds a new flag PARALLEL= to the coccicheck build target and documents the new feature.
It works a lot like make's -j flag. I looked for a way to have make pass on the value of -j, but
didn't find one - if anyone knows how to do that, I'd love to hear about it!

I suppose an alternate approach would be to accomplish this via make itself, but the approach in this patch series seemed simpler to implement...

Performance is quite a bit better than single threaded. On my 6 core box, the checks generally run around 3x faster.

Feedback welcome!! :)
