------- Comment #7 from bschindler at inf dot ethz dot ch 2010-02-23 16:24 ------- Okay, the need is simply this:
I have an octree implemented using eigen. With gcc -g, it takes roughly 3 minutes to build the tree With gcc -O1 -g, it takes about 1-2 seconds for the same The problem is Eigen as it has tons and tons of small microfunctions which are needed as it's a very generic C++ math library. If I could do this: gcc -g -foptimizenamespace=Eigen it would reduce the time may be to 5 seconds, or even 10. In any case, that leads to a lot better productivity when developing. The same issue can happen with boost, or even std. See this blog post to a very impressive example: http://cplusplus.co.il/2010/01/15/tuples/ I don't really care if I cannot step into these std/boost/Eigen functions. As long I can step through my own code and look at variables I'm fine -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43149
