[Eli Friedman via Phabricator via llvm-commits]

> It's struck me as a bit of a hack; targets are free to change the names of libcalls in TLI or to include additional target-specific ones, and neither would end up in this list. LTO also depends on the accuracy of this list for correctness, since the symbol table of the link must be finalized before LTO codegen begins.

Right.

> It seems like it might be advantageous to provide a more direct way for the linker to query the code generator for this list via the LTO API; the code generator should be able to produce an accurate list from the configuration its provided by LLD.

This makes sense; I'm not sure how hard it would be to implement, though.
