I have not tried this, but a linkage type of PrivateLinkage would not add to the symbol table according to the doc.

Sorry to keep this thread alive, but I'm learning so ... There is more. The doc for GlobalValue::LinkageTypes or the C API LLVMLinkage is not as clear as the lang ref manual. See: http://llvm.org/docs/LangRef.html#linkage. I'm pointing this out because something like LinkerPrivateLinkage (LLVMLinkerPrivateLinkage), or another one, might be more appropriate to your throw away use case (if I understand your use correctly). One should test this of course, and/or one of the experts could chime in hint hint. :-) Anyway thought this info. might be useful, however rehashed. Garrison...

Hi, I have migrated an LLVM front-end from LLVM 3.5 to 3.8 and now to 3.9 and ORC, and there is a concept which I could not transfer. Consider: extern "C" { void somefunc() {} } … auto llvmfunc = llvm::Function::Create(type, llvmFunction::PrivateLinkage, "bla", module)); executionengine.addGlobalMapping(llvmfunc, &somefunc); // now I have llvmfunc to work with and don't need to consider anything else The GlobalMappingLayer class seems to provide the functionality I want. I oriented myself on the example from https://github.com/...

Let me clarify my question. I have a struct array h1 as follows: dhash h1[10]; I want to get a Constant* to variable h1. It looks like I can use ConstantStruct::get(StructType*, ArrayRef<Constant *>) to do this. My question is how to get the second argument of type ArrayRef<Constant *> from the above variable h1.

I've built chromium with " -fprofile-instr-generate -fsanitize=address" -- the performance looks good! The file format from r198638 is indeed rudimentary. Do you already know how the real output format will look like? Just to summarize what I think is important: - minimal size on disk, minimal amount of files - minimal i/o while writing to disk, no lockf or some such -

...ble definitions are therefore imported and available. 4 Static Values File static functions and variables have local linkage types (i.e. internal or private), and are discardable. These values need special handling during importing as described below. The local linkage types InternalLinkage and PrivateLinkage (private is the same as internal but is omitted from the symbol table) are handled the same for ThinLTO. 4.1 Static Variables Read-write or address taken static variables must always be promoted to global scope (i.e. non-discardable, non-local linkage) if they are imported to another module.
