Enable -Zshare-generics for inline(never) functions This avoids inlining cross-crate generic items when possible that are already marked inline(never), implying that the author is not intending for the function to be inlined by callers. As such, having a local copy may make it easier for LLVM to optimize but mostly just adds to binary bloat and codegen time. In practice our benchmarks indicate this is indeed a win for larger compilations, where the extra cost in dynamic linking to these symbols is diminished compared to the advantages in fewer copies that need optimizing in each binary. It might also make sense it expand this with other heuristics (e.g., `#[cold]`) in the future, but this seems like a good starting point. FWIW, I expect that doing cleanup in where we make the decision what should/shouldn't be shared is also a good idea. Way too much code needed to be tweaked to check this. But I'm hoping to leave that for a follow-up PR rather than blocking this on it. |
