Instead of joining on the scheduler threads, instead keep a count of active
schedulers. When there are no more schedulers raise a signal for the main
thread to continue.
This will be required once schedulers can be added and removed from the
running kernel.
* Renamed str::split -> str::split_byte
* Renamed str::splitn -> str::splitn_byte
* Renamed str::split_func -> str::split
* Renamed str::split_char -> str::split_char
* Renamed str::split_chars_iter -> str::split_char_iter
* Added u8::is_ascii
* Fixed the behavior of str::split_str, so that it matches split_chars
and split (i.e. ["", "XXX", "YYY", ""] == split_str(".XXX.YYY.", "."))
* Fixed str::split_byte and str::splitn_byte so that they handle
splitting UTF-8 strings on a given UTF-8/ASCII byte and also handle ""
as the others do
Closes #1728
Comments out a section of debuginfo.rs. This code was already broken
(only being called when --xg was passed, and only working on trivial
programs).
It is now no longer needed to have a ty::ctxt to get at the contents
of a ty::t. The straight-forward approach of doing this, simply making
ty::t a box type, unfortunately killed our compiler performance (~15%
slower) through refcounting cost. Thus, this patch now represents
ty::t as an unsafe pointer, assuming that the ty::ctxt, which holds
these boxes alive, outlives any uses of the ty::t values. In the
current compiler this trivially holds, but it is does of course add a
new potential pitfall.
ty::get takes a ty::t and returns a boxed representation of the type.
I've changed calls to ty::struct(X) to do ty::get(X).struct. Type
structs are full of vectors, and copying them every time we wanted to
access them was a bit of a cost.
This allows a 'Name:' to appear in front of an iface declaration's
name, which will cause 'Name' to refer to the self type (with the same
number of type parameters as the iface has) in the method signatures
of the iface. For example:
iface F: functor<A> {
fn fmap<B>(f: fn(A) -> B) -> F<B>;
}
