Binary Analysis: Decompilation Fidelity

When to use

• Decompiling a function (Ghidra/IDA/objdump) and writing the "equivalent" C.
• Reviewing decompiled output before trusting it or patching from it.
• Deciding whether a round-trip succeeded: disassembly → code → binary → behavior.
• Reasoning about why a model's "clean-looking" reconstruction diverges at runtime.

When not to use

• Reading disassembly purely to understand register/addressing mechanics — use asm-x86-64-registers-and-addressing.
• Recovering types from instruction-width patterns — use binary-analysis-type-recovery.
• Reading compiler-optimizer artifacts (-O2 shapes, tail calls) — use asm-optimizer-artifacts.
• Analyzing shellcode bytes — use reverse-engineering-shellcode-analysis.
