...Basically any function that was still to be materialized wasn't getting its body copied over during linking. The only line of code that differs when you set LinkOnlyNeeded is in LinkModules.cpp -> ModuleLinker::linkIfNeeded: if (shouldLinkOnlyNeeded() && !(DGV && DGV->isDeclaration())) return false; The isDeclaration() for functions has a call to isMaterializable(). Things I've tried: * If I don't pass LinkOnlyNeeded but still link from the lazily loaded runtime module into the user module, it works (albeit it is orders of magnitude slower like...

Hello, I found a function call Function::isDeclaration() in llvm 2.5 (I know that's ancient...), which is useful to me, but I can't find it in the later version 3.3, nor the latest 3.7.....Therefore, is there an alternative way to check whether the function is just a declaration or a definition ? PS: I read the source code of llvm 2.5,...

...OnFunction(), you should check to see if the function F is a declaration before calling getAnalysis(F). Calling getAnalysis<FunctionPass>() on a function that is a declaration will trigger an assertion if the function is just a declaration.

Hi, I have a llvm pass in hand written by other people.

John, This did not work. It compiles (isDeclaration was the name of the function) and I passed a reference (&F) (F is a function pointer).

Hi, GlobalsAA, during propagation of mod-ref behavior in the call graph, looks at library functions (in GlobalsAAResult::AnalyzeCallGraph: F->isDeclaration() check), for attributes, and if the function does not have the onlyReadsMemory attribute set, forgets it. I noticed that library functions such as malloc/realloc do not have the attributes doesNotAccessMemory or onlyReadsMemory respectively set (FunctionAttrs.cpp). This leads to a loss of Gl...
