To use GNU lightning, you should include the `lightning.h' file that is put in your include directory by the `make install' command. That include files defines about four hundred public macros (plus others that are private to GNU lightning), one for each opcode listed above.
Each of the instructions above translates to a macro. All you have to
do is prepend
jit_ (lowercase) to opcode names and
(uppercase) to register names. Of course, parameters are to be put
between parentheses, just like with every other CPP macro.
This small tutorial presents three examples:
|2.3.1 A function which increments a number by one|
|2.3.2 A simple function call to ||A simple function call to printf|
|2.3.3 A more complex example, an RPN calculator|
|2.3.4 Fibonacci numbers||Calculating Fibonacci numbers|
