Hi - attached is a patch to enable building DragonEgg (x86_64) for LLVM3.3 and LLVM3.4. That is, add these changes to the 3.3 release, and it becomes possible to build DragonEgg against a llvm3.4 compiler.

If so, can you point me to a description of how I should change our code? Should I bug someone else about this problem? Should this API change be documented in

Hello Adrian, sorry for the delay with the response. Somehow I missed your message..

Hello, I'm using DIBuilder to create debugging information, I'm not clear about two things: [1] Could you help explain the meaning and the difference between"alignment" and "offset" of a type ? e.g class Actor{ int age; const char* name; } Besides, I found the denotation of createMemberType and createStructType both have "Member

Hi list, Is there a standards based reason why the DIFlags enum is set to uint32_t[1]? I am sure my DWARF-std-reading-fu is not up to snuff and so I cannot seem to find it. The reason I ask is that we are running out of space for our own DIFlags and would like to nail this down before deciding on an approach. Thanks! Sohail [1] The code in question:
