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.

...an pass this information through DILineInfoSpecifier. In fact, probably it makes sense to change the layout of this structure: there would be 3 types of file/line info (None, Regular, AbsoluteFilePath). (though, probably we may make latter the default) and 3 types of function name info (None, Name, LinkageName). > > > On Wed, May 7, 2014 at 2:36 PM, Alexey Samsonov <samsonov at google.com>wrote: > >> >> On Wed, May 7, 2014 at 11:33 AM, Eric Christopher <echristo at gmail.com>wrote: >> >>> Have you checked out llvm-symbolize?
