Thanks! I'll create a wrapper for WriteBitcodePass. Do I still need the PrepareForThinTLO pass or is the writeBitCodePass enough?

You need to make sure that your bitcode file has a module summary index. You can do that either by creating a WriteBitcodePass with EmitSummaryIndex set to true or by calling WriteBitcodeToFile with a module summary index that you created yourself. It doesn't look like either of those options are hooked up to the c API, though. Peter On Fri, Mar 30, 2018, 00:50 Carlo Kok via llvm-dev <llvm-dev at lists.llvm.org&gt...

I'm using llvm-c (but if needed can call c++ stuff too if nedeed); what's the proper way to emit bitcode with thinlto info so the linker can parallelize ?I'm currently using: unwrap(PMB)->PrepareForThinLTO = b; on the pass manager builder, but that doesn't seem to be enough? -------------- next part -------------- An HTML attachment was scrubbed...
