The thing that's missing is static link semantics that don't suck.

  So let's fix the problem! How can we get better semantics? Have any hypothetical solutions in mind?

    I've outlined it already, but let me do it again for you: 1) when making a static link archive (a .a file), include a .o with a static symbol(s) whose values(s) records the metadata that ELF would have recorded, which here is: a) dependencies, b) how to find them, c) the mapfile / version-script (at least which symbols are symbolic, protected, or demoted to local, and which, if any, are interposers. 2) on final link-edits only the direct dependency -lfoo arguments should be needed, and then link-editor should find the dependencies' dependencies... by looking at the metadata recorded in the .a files. Really, it's very simple. libstool is a very bad attempt at layering this on top of the linker (recording metadata in .la files), but it doesn't work well. This functionality has to be in the linkers.

      Is it literally called libstool…
