import "cmd/internal/obj" p := &obj.Prog{ As: obj.AADD, // set the opcode to ADD From: obj.Addr{Type: obj.TYPE_REG, Reg: obj.RAX}, // set the source operand to RAX To: obj.Addr{Type: obj.TYPE_REG, Reg: obj.RBX}, // set the destination operand to RBX }
import "cmd/internal/obj" m := &obj.Mark{Type: obj.PCDATA, Pos: 123, Sym: someSym} // create a Mark object with a specific position and symbol p.Mark = append(p.Mark, m) // add the mark to the Prog's list of metadataThis adds a new Mark to the Prog's metadata list, indicating that at position 123 in the assembly code, someSym is the active symbol. Overall, the cmd/internal/obj package is a low-level library that is primarily used by the Go toolchain itself. Developers working on compilers, assemblers, or other tools that need to manipulate Go object files may find it useful.
