city

city is a JIT compiler infrastructure written in C++.

It provides a simple llvm-like builder API that is used to generate city-ir. This IR can then be compiled to any of the supported architectures.

Supported Platforms

city is tested and developed for support on the following platforms and compiler versions:

OS	Architecture	Compilers
Windows 10/11	Amd64/x86_64	MSVC 2022, GCC 14, Clang 19
MacOS 15	AArch64	Apple Clang 15
MacOS 15	Amd64/x86_64	Apple Clang 15

Linux support is planned for GCC 14 and Clang 19.

Goals

city aims to:

• Support aarch64 and amd64 on Windows, MacOS, and Linux.
• Be free of any third-party dependencies.
• Provide a simple API.
• Prioritize compilation speed over runtime speed in order to excel at compiling and running small, short-lived functions.
