I've been asked how LTO in LLVM compares to equivalent capabilities in GCC. How do the two compare in terms of scalability? And robustness for large applications? Also, are there any ongoing efforts or plans to improve LTO in LLVM in the near future? Any information would be much appreciated. Thanks, --Vikram S.

I'm trying to decide whether to use either the MIPS or ARM back ends for course projects in our introductory compiler class. I'd like to use something that has a stable back end, so that the students can use the selector, probably without changes, and do a project on register allocation and stack layout. We don't have MIPS or ARM hardware (other than possibly a few donated Android
