X-Git-Url: http://wien.tomnetworks.com/gitweb/?a=commitdiff_plain;h=ddc2a6234f9c2a8e0f199db3a10837c317ca3de5;p=mono.git

Change the linkage of the type_info symbols generated by the LLVM backend, since using LLVMPrivateLinkage causes LLVM to generate assembly which is not allowed by clang. Fixes #10811.
