Compiling non-native constants

Techniques for compiling non-native constants are disclosed. While compiling source code instructions, a compiler determines that a particular source code expression is associated with a command to the compiler to resolve the particular source code expression as a constant during compilation. The compiler is not configured to recognize the particular source code expression as constant without the command signaling to the compiler that the particular source code expression is constant. Based on the command, the compiler executes the particular source code expression to obtain a constant value. The compiler generates compiled instructions based on the source code instructions, in which the constant value is substituted for at least one reference to the particular source code expression.
