The title is wrong. This is not a C++ to x86 JIT (which would be really cool), this is a JIT library for C++ (of which there are a number). It has it's own doma

The title is wrong. This is not a C++ to x86 JIT (which would be really cool), this is a JIT library for C++ (of which there are a number). It has it's own domain specific language for expressions. It doesn't take arbitrary C++. No std C++ syntax, no classes, etc. Ex: // nativeJIT DSL auto & area = expression.Mul(rsquared, expression.Immediate(PI)); auto function = expression.Compile(area); // C++ auto area = rsquared * PI;
