Hi, I am working on the COFF backend and am wondering where llvm.memcpy gets lowered to memcpy ? It seems to be done by the assembler backends and would have thought it would either be done by a lowering pass or done by the mangler but it does not seem to be either. Many thanks in advance, Aaron -------------- next part -------------- An HTML attachment was scrubbed... URL:

In LLVM IR metadata is used to attach auxiliary information with various IR constructs. Currently metadata information is represented using MDNode and MDString. The metadata can refer to LLVM values but these references are not counted as regular "uses" of these values because metadata is maintained 'on the side'. This ensures that the optimizer is not influenced by auxiliary

The code generator does not generate any code for these NamedMetadata so we can just use vanilla default values here without any harm. - Devang
