How to execute machine code programatically in golang?

[kant kodali]

Hi All,

I was trying to see how I can execute machine code programmatically in golang. Here is an example I have so far https://go.dev/play/p/5HL1ydr5IUy but this results in a segfault when I finally call the function in the end. Any idea how to fix this? 

Thanks,

Kant

Do you mean inline assembly like behavior?

A func value is a pointer to a word containing the address of the
code; in other words, it's doubly indirect. (The code generated for
f() is a load from f followed by an indirect CALL.) So, you need to
introduce another level of indirection. Also, the logic for the unsafe
coercion is wrong: it lacks an & operator, so you need a second level
of indirection.
