[Question][Hw3] Function definition position

[cskwak99]

Hello,

I have a question about function location in Llvm IR.
Is always callee function definition located above caller function definition? It seems natural, but I saw function declarations are located at the bottom, although some caller function exists above.
How can I understand it?

Can we see an example?

I think this is common for languages that are compiled (like c++ & ocaml). You don't need to delare a function before use (like in python)

Can we see an example?

I mean, when we declare function dbs_sanitizer or coverage, its declaration goes below main function definition. Although we use it it above.

That does not matter.
If you are not sure, you can compile the LL files and execute the program.

I checked it execute well but just confused. I think my thought was buried in C language style. Thanks for answers
