Hi, Having just found an ABI conformance bug in a compiler front-end, I am curious: is the state of target-independent argument lowering in LLVM still the same as when this thread was taking place?: http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-February/thread.html#59387 Vadim -------------- next part -------------- An HTML attachment was scrubbed...

There's one small difference between the two: with the 64 bit ELFv1/ SVR4 ABI, tail padding for structs passed by value is only performed in case the struct is larger than 8 bytes, while for AIX 64 bit it's always done. As an aside, on Darwin/ppc64 it's done if the

Hi Jonas. I'm very interested in an llvm backend for freepascal. Could you give some more details? Is there already something to try and test? Will the code be avaiable on svn?
