...MainClass's array after the transfer, and print it out, then it does so successfully, then continues to segfault. So it looks like it's copied the memory okay, but I've corrupted something in the process.. -- View this message in context: http://old.nabble.com/Size-of-structs---arrays-tp33341964p33381946.html Sent from the LLVM - Dev mailing list archive at Nabble.com.

I'm trying to work out the size of a struct so that I can pass this to the 'llvm.memcpy' intrinsic. It's easy to find out how I'm supposed to do this, as I keep seeing the following: %Size = getelementptr %T* null, int 1 %SizeI = cast %T* %Size to uint But I'm unsure how I actually do this in the C++ API. Is the 'null' here a llvm::ConstantPointerNull? Any help
