This patch moves core implementation of llvm-objcopy into Object library (http://lists.llvm.org/pipermail/llvm-dev/2020-September/145075.html). The functionality for parsing input options is left inside tools/llvm-objcopy. The interface of ObjCopy library: ObjCopy/ELF/ELFObjcopy.h ``` Error executeObjcopyOnIHex(const CopyConfig &Config, MemoryBuffer &In, Buffer &Out); Error executeObjcopyOnRawBinary(const CopyConfig &Config, MemoryBuffer &In, Buffer &Out); Error executeObjcopyOnBinary(const CopyConfig &Config, object::ELFObjectFileBase &In, Buffer &Out); ``` ObjCopy/COFF/COFFObjcopy.h ``` Error executeObjcopyOnBinary(const CopyConfig &Config, object::COFFObjectFile &In, Buffer &Out); ``` ObjCopy/MachO/MachOObjcopy.h ``` Error executeObjcopyOnBinary(const CopyConfig &Config, object::MachOObjectFile &In, Buffer &Out); ``` ObjCopy/wasm/WasmObjcopy.h ``` Error executeObjcopyOnBinary(const CopyConfig &Config, object::WasmObjectFile &In, Buffer &Out); ``` Differential Revision: https://reviews.llvm.org/D88827
