AsmJit is a JIT and AOT assembler library for generating x86/x64 machine code at runtime in C++. You build code by calling C++ methods that correspond to assembly instructions, load it into executable memory, and call it through a function pointer; it also provides a Compiler layer that allocates virtual registers. It has no external dependencies, has added an AArch64 backend, and is used in the JIT pipeline of the Blend2D renderer.
