# FLIRT

FLIRT stands for [Fast Library Identification and Recognition Technology](https://hex-rays.com/products/ida/tech/flirt/in_depth). This technology allows IDA to recognize standard library functions generated by [supported compilers](https://hex-rays.com/products/ida/tech/flirt/compilers) and greatly improves the usability and readability of generated disassemblies. Of course, FLIRT can be combined with IDA’s usual interactivity to further improve the analysis. See this [Pascal](https://github.com/HexRaysSA/docs/blob/IDA-8.4/user-guide/signatures/supported-compilers/turbo-pascal.md) and this [Delphi](https://github.com/HexRaysSA/docs/blob/IDA-8.4/user-guide/signatures/supported-compilers/delphi.md) example as well.
