Decompile Assembly to Readable C

Converting Assembly to C transforms low-level machine instructions into human-readable high-level code. Our AI converter analyzes assembly patterns to reconstruct C-like code, translating instructions to operations, registers to variables, and jumps to control flow. Perfect for reverse engineering compiled binaries, understanding compiler output, modernizing hand-written assembly in legacy codebases, or learning how C constructs compile to assembly. Note that decompilation is inherently imperfect - variable names are lost, types must be inferred, and complex optimizations can produce unusual C patterns. The converted code is functionally equivalent but may require manual cleanup for optimal readability.

Conversion Features

Instructions to Operations

Converts assembly instructions to C operations. MOV becomes assignment, ADD/SUB/MUL become arithmetic operators, CMP/TEST become conditions, and bitwise instructions (AND/OR/XOR/SHL/SHR) map to C bitwise operators.

Control Flow Recovery

Reconstructs control flow from jumps and branches. JMP/JZ/JNZ become if/else/while/for statements, function calls (CALL/RET) convert to C functions, and labels become structured control flow.

Registers to Variables

Maps assembly registers to C variables. Register usage patterns determine variable scope and lifetime. EAX/RAX often become return values, function parameters map to calling conventions, and local variables come from stack usage.

Type Inference

Infers C types from assembly operations. Integer operations suggest int/long types, floating-point instructions indicate float/double, pointer arithmetic identifies pointer types, and structure access patterns reveal struct layouts.

FAQs

How accurate is Assembly to C conversion?

Assembly-to-C conversion is an approximation - assembly maps to multiple possible C implementations. The converter produces functionally equivalent C code that mirrors assembly logic, but variable names, types, and high-level constructs are inferred and may differ from original source.

Can it handle different assembly dialects?

Yes! The converter supports x86/x64, ARM, MIPS, and other architectures. Instruction sets convert to equivalent C operations - MOV becomes assignments, ADD/SUB become arithmetic, JMP/JZ become control flow, and registers become variables.

What about assembly optimizations?

Assembly-level optimizations (register allocation, instruction scheduling) convert to equivalent C logic. The resulting C code may not be optimally written but preserves functional behavior. Manual cleanup improves readability after conversion.
