When a go program is called from C, is it compiled or interpreted?

I made a C program. And I made a go file with go functions defined.
In the C program, I called go functions. Is go called from C compiled or interpretted?

it is always compiled. C will never run function without compilation.

You made a Go program which calls C functions (the other way around is not yet possible.) Then you're apparently calling Go functions from C again which is a bit weird and doesn't make much sense most of the time. See https://stackoverflow.com/a/6147097/532430.

I'm going to assume you used gccgo to compile your program. Because if you used Go's gc then there wouldn't be any confusion about what language your program is written in.

It's compiled. gccgo is a Go front-end for GCC. And GCC stands for GNU Compiler Collection.

In your program when you first call the go function,the compiler will generate the necessary codes for function call,space for function arguments,store details about function arguments type etc.
If everything is correct as per the compiler standard,object file is created and further there are other processes like linking and all.
So basically you cannot say it as " Is go called from C compiled or interpretted?",it's a series of processes which works together to make your program run.
