A common tool is reflection: the ability of a process to examine, introspect, and modify its own structure and behavior.

When you compile code for the runtime, it is converted into common intermediate language (CIL) and placed inside a portable executable (PE) file along with metadata generated by the compiler. Attributes allow you to place extra descriptive information into metadata that can be extracted using runtime reflection services. |

Clang, LLVM, GCC, and MSVCLLVM is an umbrella project, with several sub-projects, e.g. LLVM Core and Clang. LLVM Core libraries provide an optimizer and code generator for different CPUs. Clang is an “LLVM native” C/C++/Objective-C compiler which aims for fast compilation, useful error and warning messages, and a platform for building source-level tools. The Clang Static Analyzer and clang-tidy are examples of such tools. So if I were to create a programming language, I can define a transformation into LLVM intermediate representation (LLVM IR), and that will make use of LLVM core to optimize it? Sweet! ... |
Example of reflection in C#: All types descended from the
...System.Objectbase class (the root of the type hierarchy in .NET) inherit theGetType()method.
