[Llvm-bgq-discuss] november patches

Fri Dec 21 19:31:42 CST 2012

Michael, et al.,

I've updated our local install on vesta to r170456-20121221. I've attached the corresponding patches. This version includes a new loop data prefetching optimization that I've been developing. For our install, I rename the attached wrapper script to bgclang and create a symlink to it called bgclang++ for use with C++ sources. I'll also post these on the web site sometime in the near future.
