In PL/I compilation, what is “resolving symbolic address and generating machine language” associated with________________?
Show answer Hide answer
Answer: D. Assembly and output
Explanation
The assembly and output phase of compilation resolves symbolic addresses into absolute machine locations. It generates the final machine language object code that the computer hardware can execute directly. This phase completes the translation pipeline by finalizing instruction opcodes and memory references. Compiler design involves multiple sequential phases including lexical, syntactic, and semantic analysis. Symbolic addresses used during programming must be mapped to physical memory addresses before execution. Object code generation transforms intermediate representations into binary machine instructions.
Compiler engineers study these translation phases to optimize code generation and reduce binary sizes. Understanding compilation stages helps developers diagnose linking errors and address resolution failures. Code generation bridges high-level abstractions with underlying hardware execution mechanisms. Syntax analysis focuses on checking grammar rules and building parse trees from source code tokens. Code generation translates intermediate representations but address resolution belongs to the final phase. Storage assignment allocates memory segments for variables but does not generate the final machine language.
