Hi Geoff, We use LLJIT. Do addObjectFile() and StaticLibraryDefinitionGenerator work > for ELF objects? They do. :) I've not tested StaticLibraryDefinitionGenerator extensively on Linux. but we have a regression test checking basic usage. If you run into any trouble at all please file a bug and assign it to me. -- Lang. On Mon, Sep 28, 2020 at 2:05 PM Geoff Levne...

...ctLinkingLayer and use the 'add' method. - For an LLJIT instance you can just call the 'addObjectFile' method. - For the OrcV2 C API you can call the 'LLVMOrcLLJITAddObjectFile' function. For static libraries: - For raw OrcV2 components or an LLJIT instance you can attach a StaticLibraryDefinitionGenerator [1] to the JITDylib that you would like to load the library into. See [2] for an example. - For the OrcV2 C API we will just need to add a method to wrap the operation above. We already have 'LLVMOrcCreateDynamicLibrarySearchGeneratorForProcess'. We should add counterparts to that to load d...

...rror reporting. A few people in the community are working on an ELF/x86-64 implementation of JITLink at the moment -- Once we have that you should get small code model support and better error handling. -- Lang.

Hi Andres, A topic that I'd find interesting is what it'd take to make it easier to > use profile guided optimization in the context of JIT.

We couldn't go into detail, but we could kick off a discussion and
