...them. The performance is obviously terrible, but this punts all the ObjC/Swift metadata parsing to ld64 and dyld (and you get debug info for free!) so it is handy for prototyping. Let me know if you would like me to share the code for that. Cheers, Lang.

Hello, It is likely that I missing something however I have to ask. We are working on Mull project https://github.com/mull-project which deals with LLVM IR in the first place so it is often that we encounter errors like the following one when we do things like parseAssemblyString(IR, Err, GlobalCtx);`: ``` test: <string>:7237:187: error: invalid field 'variable' !1526 = distinct

Hi all, I am having hard time figuring out how I should use the API for JIT in LLVM 6. In LLVM 3.9 I am used to adding all objects at once and emitAndFinalizing them all: handle = objectLayer.addObjectSet(objectFiles, memoryManager, resolver); objectLayer.emitAndFinalize(handle); In LLVM 6.0 the objects are added one by one: auto handle = objectLayer.addObject(objectFile, resolver).get();

Hi all, > I actually looked into this recently. It is possible, but takes some non-trivial effort right now: You have to hook into the JIT memory allocator, parse the objective C metadata sections in the object file, then call the objective C runtime to register any newly added classes, protocols and selectors. > I can't release my code as-is: I built it against a hacked up copy of the
