Experiment with interpreted glue #527
Comments

That seems like it will trade compile time for run time, which seems like not something we want to do? On the other hand, it might be a win because of cache effects... Hm. |

Yeah, I think it's worth trying. I think this is what OCaml does at least. At the very least it should help -O0. |

I believe this 'experiment' is successful, yes? Closing. |

add tmpnam and pthread_exit
tmpnam and readdir are trivial IMO.
About the `pthread_create` change: It needs `unsafe` for passing `C` functions to pthread_create (with rust functions the omission of `unsafe` is working of course).
`bindgen` produces this function definition:
```
pub fn pthread_create(arg1: *mut pthread_t,
arg2: *const pthread_attr_t,
arg3: Option<unsafe extern "C" fn(arg1: *mut c_void) -> *mut c_void>,
arg4: *mut c_void) -> c_int;
```
So it would add an additional `Option` around the function. But that would break existing code which uses `libc::pthread_create` and what use is it to call pthread_create without any function pointer, so I left `Option` out.
For reference: I also opened a [stackoverflow question](http://stackoverflow.com/questions/42284562) where the answers were also suggesting adding `unsafe` to the function definition.

The `proc_macro` feature has stabilized in the compiler and usage of it largely needs to switch to `use_extern_macros` now.

We spend lots of time generating glue, even for stuff like cmp glue that is cold. We could emit a declarative description of the type and have a generic "cmp" function that uses that description.
