Tiger

Tiger is a Delphi-hosted compiler infrastructure that lets you generate native x86-64 binaries for Windows and Linux — executables, shared libraries, static libraries, and object files — entirely from code. There is no source language to parse. Instead, you construct programs using a fluent Delphi API: define types, declare functions.
