...s fed, Module by Module, into the ORC JIT? I'd like to add a Module compiled from C++ code into the JIT and then as I add later modules, functions from the first module are inlined in the later ones. I already do this for file compilation/linking in my Common Lisp compiler “Clasp” (github.com/drmeister/clasp <https://urldefense.proofpoint.com/v2/url?u=http-3A__github.com_drmeister_clasp&d=DwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=Mfk2qtn1LTDThVkh6-oGglNfMADXfJdty4_bhmuhMHA&m=sSykZW5nIEBIoQEQoyEQF3iTvIwIffdEAf9FkbyVYz0&s=ao0EQZ_k7esDdMap8YjoO52BiKyMRHBv7PG4XJdrBOc&e=>).

This is the only thing that I’ve found that works in terms of getting the exception to propagate out of the JITted function - change the “call” to an “invoke” and hook in the do-nothing landing-pad. https://gist.github.com/drmeister/7a35046f666826206973 Compare line 646 of the file above to the one that I just posted. > https://gist.github.com/drmeister/b97dec956c6ee9ffeb75 The first one propagates the exception and the second one fails.

Hello everyone, Is fully relocatable/position-independent JITted code on the horizon or currently possible with LLVM? I’ve written a Common Lisp compiler (currently called Clasp: https://github.com/drmeister/clasp) in C++ that uses LLVM as the backend and interoperates with C++. It uses copying garbage collection via the Memory Pool System (MPS) garbage collector by Ravenbrook. This garbage collector is precise on the heap and conservative on the stack. Currently I JIT code to wherever LLVM drops th...

...d pass it on to anyone else you think may be interested. Please send any tips or feedback to <asb at asbradbury.org>, or @llvmweekly or @asbradbury on Twitter. ## News and articles from around the web An implementation of Common Lisp with an LLVM backend, Clasp, [has been announced](http://drmeister.wordpress.com/2014/09/18/announcing-clasp/). There's a lot of work to be done on performance, but development is [very active on Github](https://github.com/drmeister/clasp). A backend for the educational 'y86' instruction set architecture has [been started](http://article.gmane.org/gma...

...replace the runConstructors/runDestructors API in LLJIT (providing equivalent functionality: initializers will be discovered by scanning llvm.global_ctors/llvm.global_dtors), and will enable the development of platform specific initializer-support implementations. -- There’s a long-ish chat with @drmeister on the discord #llvm channel about RuntimeDyld vs JITLink, and large vs small code model. -- I have added a new LLJIT example program that demonstrates how to use lazy-reexports in ORCv2 to add lazy compilation: llvm/examples/LLJITExamples/LLJITWithLazyReexports. -- COFF support in the JIT still...

I’m developing a Common Lisp compiler for OS X and Linux that uses LLVM as its backend and interoperates with C++. It’s at: github.com/drmeister/clang I need to compile one C++ source file containing small, intrinsic functions into an LLVM-IR bitcode file and link it with bitcode generated by my compiler running LLVM3.6.1. I have been unable to do this for more than a year and I was hoping that Apple would catch up. If anyone has sugges...

Hi Christian, Thanks for your explanation. I know your situation now. I would suggest you to check the optimization pass used by the JIT compiler, especially IPO/PruneEH.cpp. It will try to add nounwind attribute to functions which will result in the problem you have mentioned earlier. Alternatively, as a workaround, try to add uwtable (function attribute) to the functions that are generated
