Reading Disassembly in Ghidra and GDB

Ghidra

• Free, NSA-built; Listing view (asm) + Decompiler (C-like) side by side.
• Right-click to rename variables/functions as you understand them.
• Function graph view shows basic blocks and control flow.

GDB

• set disassembly-flavor intel — use Intel syntax.
• disassemble main — dump a function's asm.
• info registers — view RAX, RIP, RFLAGS, etc.
• x/16xb $rsp — examine 16 bytes at the stack pointer.
• layout asm / layout regs — live TUI views.
