restore-function-signatures

Restore missing parameter types by inferring correct return types, parameter names, and calling conventions from call-site and body evidence. This process repairs degraded decompiled C/C++ pseudocode, replacing generic placeholders with meaningful, compilable function signatures.

Fix CWE-457 style issues by detecting parameters dropped by signature-degrading casts and reintroducing the missing arguments. This restores the original memory semantics and data-flow edges compromised during decompilation.

Yes, you can recover function signatures from IDA Pro or Ghidra decompiled code. The process targets degraded C/C++ pseudocode where signatures are generic, restoring them while preserving dereference depth and data-flow paths.

Ensure restored decompiled function signatures compile correctly by performing strict GCC compilation verification after applying signature edits. Changes are gated by cross-validation confidence to guarantee memory semantics are preserved.

Decompiled code shows generic __int64 types because decompilers replace real function signatures with generic types and placeholder names to match undefined behavior. This makes recovered C/C++ code hard to compile and understand without signature restoration.
