...'. 'struct_ptr' is a pointer to the struct I'm trying to size. I've also tried using getNullValue on the struct's own type. Sorry to ask so directly, but I'd quite like to get this sorted. -- View this message in context: http://old.nabble.com/Size-of-structs---arrays-tp33341964p33374459.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
