llvm dev - Sep 2017 - LLD: Calling from within LLVM

Hello everyone

I was wondering if there was a way to call LLD from code within LLVM. More
concrete: I am working in Polly, and I am trying to link an ELF relocatable
object file into an ELF shared object file. Is there a way to  run an LLD
pass from within the code?

Thank you in advance for any pointers!
Best,
Philipp Schaad

There currently isn't any way - the layering isn't really setup that way
for one thing (lld depends on llvm, not the other way around). But it might
be nice to sink some.of lld's libraries into llvm(they'd need a bunch of
refactoring to become reusable libraries) for use in the jit or other
places.

I see, too bad! Indeed, I agree that this would be a very useful thing to
do at some point.
Thank you a lot for pointing this out!
