llvm dev - Nov 2012 - [LLVMdev] Automating Analysis Pass at linktime question [liblto] [safecode]

Hello all,

I'm a research assistant at the University of Wisconsin and we're trying
to
come up with a general way to run our whole program analysis over programs
that may use different methods to perform the build.  I saw some discussion
that liblto could be used for this (and safecode successfully did it) for
llvm 2.6 - 3.0, but that doesn't seem to be working the same way with llvm
3.1+.  Is it still possible to install our pass into liblto directly
anymore?  Is there perhaps a better way to have the linker intercept and
run our analysis not using liblto?

Thanks,
--Henry Abbey

We're successfully using libLTO with SAFECode mainline which is now 
tracking LLVM mainline.  What platform are you on, and what problems are 
you having?  Is the issue that the linker isn't running libLTO at all, 
or is the problem that the linker is not loading your modified version 
of libLTO?

I don't know of anything better than libLTO.
