[llvm-dev] LTO on libraries

[David Callahan via llvm-dev]

Hello,

Is there a combination of the current tools would would allow me to apply LTO to a set of object files where are less than an entire application? Similar to “ld –r”  for doing a partial link.
I assume it would start with “clang –flto –c {a,b,c}.c” but the a subsequent link step fails  do to unresolved references of course.
Using llvm-link will linke the bitcode files but does not trigger compilation.

Thanks
david
