llvm dev - Aug 2010 - [LLVMdev] llvm-link and ld option --whole-archive

Hello list,

On linux, ld has the following option:

       --whole-archive
           For each archive mentioned on the command line after the
           --whole-archive option, include every object file in the archive
in
           the link, rather than searching the archive for the required
object
           files.  This is normally used to turn an archive file into a
shared
           library, forcing every object to be included in the resulting
           shared library.  This option may be used more than once.

It would be convenient for similar functionality to exist in llvm-link for
handling archive files being transformed into shared libraries.  The
equivalent functionality can be achieved in a straightforward manner by
exploding the archive files first, but this makes integration into existing
build systems difficult and/or tedious.

Generally speaking, is the goal of llvm-link to be full featured, or just to
fill in as a bitcode linker for the time being?

I think the idea is for llvm-link to be a very simple linker and
llvm-ld the one that looks a bit more like a system linker. You can
also try using the gold linker. It *is* a system linker, so all
options you expect will be there and it can handle LLVM bitcode via a
plugin.
