Seems to be something wrong with the buildbot - I can't see why it's complaining. Garth On 04/09/10 11:56, Anders Logg wrote: -O2 also makes more sense.

All of the problems seem to come from the Python tests and demos with std::bad_cast. Perhaps something with the SWIG layer? -- Anders On Sat, Sep 04, 2010 at 12:02:19PM +0100, Garth N.

I changed to -O2 for the same reason in the Dorsal PETSc package file. I think -O3 is ok for PETSc but I think of -O2 as optimize and -O3 as try even harder. -- Anders ___ Mailing list: https://launchpad.net/~ffc Post to : ffc@lists.launchpad.net Unsubscribe : https://launchpad.net/~ffc More help : https://help.launchpad.net/ListHelp

It might be that the dolfin wrapper file it too large. But I have tried compiling the a much smaller wrapper code and it also bailed out for -O3.

It might be that the dolfin wrapper file it too large. But I have tried compiling the a much smaller wrapper code and it also bailed out for -O3. I've never had a problem with -O3 when using the quadrature representation. It can be a problem for the tensor contraction, but by the time you run into this limitation the quadrature code is much faster anyway. Why I am seeing now for a particular problem is that Kristian's FFC optimisations so good that -O3 and -O0 make no difference because insertion is dominating. The tensor contraction would be more compiler friendly (and most likely efficient) if it didn't unroll loops, but used fixed size loops and let the compiler do tricks on those. Garth Johan I changed to -O2 for the same reason in the Dorsal PETSc package file.
