Eclipse OMR is a set of open source C and C++ components for building robust, high-performance language runtimes across many hardware and OS platforms. It provides reusable building blocks including a garbage collector, JIT compiler technology, threading library, platform porting layer, and test framework, derived from IBM's J9 Java virtual machine.

Use cases

• build a garbage collector for my language runtime
• add a JIT compiler to my interpreter
• cross-platform threading library for a VM
• reuse runtime components instead of writing my own GC
• port my language runtime to multiple operating systems
• build a custom virtual machine in C++

When to choose

• you are building a language runtime or VM and want proven GC, JIT, and threading components
• you need enterprise-grade runtime technology with cross-platform support
• you want to avoid reimplementing OS interfaces, signal handling, and diagnostics for your language

When to avoid

• you need a complete ready-to-use language runtime rather than components
• your project is not written in C or C++
• you only need a simple scripting language without managed memory or JIT
