..., the linkonce variable 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...

Hi John, > The -internalize pass changes globals to have internal linkage. Does this > not suffice for your needs? To my understanding, it does not. The -internalize pass performs: I->setLinkage(GlobalValue::InternalLinkage); which means it only changes the linkage mode, while global variables remain in place. And we need to *replace* globals with local variables in main and arguments - in other functions. - D. 2012/4/8 John Criswell <criswell at illinois.edu>: > On 4/7/12 7:28 PM, Dmitry N.
