示例1: symbol
explicit symbol(const SymbolRef& sym) {
StringRef name;
if(error_code err = sym.getName(name))
llvm_binary_fail(err);
this->name_ = name.str();
if (error_code err = sym.getType(this->kind_))
llvm_binary_fail(err);
if (error_code err = sym.getAddress(this->addr_))
llvm_binary_fail(err);
if (error_code err = sym.getSize(this->size_))
llvm_binary_fail(err);
uint32_t flags;
if (error_code err = sym.getFlags(flags))
llvm_binary_fail(err);
if (flags & SymbolRef::SF_Undefined) {
uint64_t addr;
if (error_code err = sym.getValue(addr))
llvm_binary_fail(err);
// This will not work for x86-64, since they usually zero
// the value. BFD library uses index correspondence
// between plt entry and relocation, to name the plt
// entry. We can't afford this.
if (addr) {
addr_ = addr;
size_ = 8;
}
}

}示例3: getSymbolOffset
uint64_t RuntimeDyldCOFF::getSymbolOffset(const SymbolRef &Sym) {
// The value in a relocatable COFF object is the offset.
return Sym.getValue();
