25 | /* |
26 | * A note on nomenclature of linking: "extern", "foreign", and "upcall". | |
27 | * | |
28 | * An "extern" is an LLVM symbol we wind up emitting an undefined external | |
29 | * reference to. This means "we don't have the thing in this compilation unit, | |
30 | * please make sure you link it in at runtime". This could be a reference to | |
31 | * C code found in a C library, or rust code found in a rust crate. | |
32 | * | |
33 | * Most "externs" are implicitly declared (automatically) as a result of a | |
34 | * user declaring an extern _module_ dependency; this causes the rust driver | |
35 | * to locate an extern crate, scan its compilation metadata, and emit extern | |
36 | * declarations for any symbols used by the declaring crate. | |
37 | * | |
38 | * A "foreign" is an extern that references C (or other non-rust ABI) code. | |
39 | * There is no metadata to scan for extern references so in these cases either | |
40 | * a header-digester like bindgen, or manual function prototypes, have to | |
41 | * serve as declarators. So these are usually given explicitly as prototype | |
42 | * declarations, in rust code, with ABI attributes on them noting which ABI to | |
43 | * link via. | |
44 | * | |
45 | * An "upcall" is a foreign call generated by the compiler (not corresponding | |
46 | * to any user-written call in the code) into the runtime library, to perform | |
47 | * some helper task such as bringing a task to life, allocating memory, etc. | |
48 | * | |
