Project Summary
AsmJit is a complete JIT and remote assembler for C++ language. It can generate native code for x86 and x64 architectures having support for a full instruction set, from legacy MMX to the newest AVX2. It has a type-safe API that allows C++ compiler to do a semantic checks at compile-time even before the assembled code is used or run.
AsmJit is not a virtual machine. It doesn't have functionality often required and implemented by virtual machines; however, it is designed to be extensible by third-parties and mostly used as a JIT backend. The usage of AsmJit is not limited, it's suitable for multimedia, virtual machines or remote code generation.
