Implementation

Implement symbol table parser and display.

Requirements:

Parse symbol table section from ELF file
Extract symbol information (name, value, size, type, binding)
Display symbols in human-readable format
Filter by symbol type (functions, objects, undefined)
Handle both local and global symbols
Show symbol visibility and section
Test with files containing various symbol types

Why This Matters

Object-file symbol tables are how nm, ld, and dynamic loaders resolve names across compilation units; undefined-symbol link errors and C++ name mangling both live here. This machinery is also security-relevant: symbol interposition via LD_PRELOAD is used both for legitimate profiling (jemalloc) and for rootkits.
