# DynaMIR

> A modern dynamic binary instrumentation engine for x86-64, ARM64, and RISC-V64, built around a custom MLIR-based IR.

DynaMIR is a dynamic binary instrumentation engine for x86-64, ARM64, and
RISC-V64. It lifts machine code into a custom MLIR-based intermediate
representation, applies instrumentation, and lowers the result back into
executable instructions.

Conceptually similar to QBDI, DynaMIR is designed around a modern, composable IR
and integrates directly with MCStone and LIEF. It provides the execution layer
for tracing, program analysis, and trace-based workflows.
