In other cases where only one argument out of many changed between versions, we put that argument on a separate line so we can version-gate it without copying the rest of the call. I'd like to see this happen here too, see LLVMRustDIBuilderCreatePointerType for an example.

#else
llvm::DIGlobalVariableExpression *VarExpr = Builder->createGlobalVariableExpression(
unwrapDI<DIDescriptor>(Context), Name, LinkageName,
unwrapDI<DIFile>(File), LineNo, unwrapDI<DIType>(Ty), IsLocalToUnit,
InitExpr, unwrapDIPtr<MDNode>(Decl), AlignInBits);
#endif

InitVal->setMetadata("dbg", VarExpr);
