[LLVMdev] LoadedObjectInfo::getSectionLoadAddress
Hi Lang,
LoadedObjectInfo::getSectionLoadAddress takes StringRef as an arg. That breaks if the object file has multiple sections with the same name. I made a change to add an overload that takes a SectionRef&. Can you please take a look?

[LLVMdev] ORC and relocations
Hello,
I'm working on LLILC (a jit for the CoreCLR built on ORC), in particular, on using LLILC as an ngen jit. I would like to have an ability to be notified of relocations that ObjectLinkingLayer is applying and to be able to tell the linking layer not to resolve certain relocations for external symbols (so that the client can do some custom resolutions later). The only way I found of
