These are no longer split out and shared in the root build/ directory. This does result in a small amount of overhead from building redundant copies of these files, although the overhead is not significant. When building 7 different variants of gem5, all the ISAs and NULL, the difference on my machine was: Before: real 41m25.372s user 914m22.266s sys 41m51.816s After: real 42m38.074s user 921m36.852s sys 43m2.949s This is about a 2-3% difference, which is a worse than typical case, since the overhead scales with the number of variants being built. The benefit of pulling ext/ into the variant directory is that there can now be a single config which applies to all files used to build gem5, and that config is represented by the variant of gem5 being built.
