示例1: addPotentialUndefinedSymbol
void LTOModule::addPotentialUndefinedSymbol(GlobalValue* decl, Mangler &mangler)
{
const char* name = mangler.getValueName(decl).c_str();
// ignore all llvm.* symbols
if ( strncmp(name, "llvm.", 5) != 0 ) {
_undefines[name] = 1;
}
}示例2: addDefinedSymbol
void LTOModule::addDefinedSymbol(GlobalValue* def, Mangler &mangler,
bool isFunction)
{
// string is owned by _defines
const char* symbolName = ::strdup(mangler.getValueName(def).c_str());

// set definition part

// and tentative definitions!
// HACK HACK HACK

// are tentative definitions

}示例3: getLTOLinkageType
// Find exeternal symbols referenced by VALUE. This is a recursive function.
static void

}

// ExternalLinkage type. Do not ignore these operands.
if (Constant *c = dyn_cast<Constant>(value))
// Handle ConstantExpr, ConstantStruct, ConstantArry etc..
