Now rustdoc_ng will be built as both a binary and a library (using the same
rules as all the other binaries that rust has). Furthermore, this will also
start building rustdoc_ng unit tests (and running them).
also removes the unused `FastInvoke` wrapper, as it's never actually
going to be used (we can't *partially* switch to `fastcc`, and this is
only used for Rust functions)
Closes#9221.
"rustpkg test" isn't implemented yet, so it shouldn't be in the manpage. Referring interested parties to the manual is probably
the right thing for now; eventually, these documents should merge.
This module was removed a while ago, but the tasks tutorial wasn't
updated, and the old docs page for pipes was never deleted so the link
confusingly still worked!
The `noalias` attributes were being set only on function definitions,
not on all declarations. This is harmless for `noalias`, but prevented
some optimization opportunities and is *not* harmless for other
attributes like `sret` with ABI implications.
Closes#9104
`push_bytes` is implemented with `ptr::copy_memory` here since this
function is intended to be used to implement `.push_str()` for str, so
we want to avoid the overhead.
Issue #8742
Add the method `.reserve_additional(n: uint)`: Check for overflow in
self.len() + n, and reserve that many elements (rounded up to next power
of two). Does nothing if self.len() + n < self.capacity() already.
It now uses `{"type": VariantName, "fields": [...]}`, which, according to
@Seldaek, since all enums will have the same "shape" rather than being a weird
ad-hoc array, will optimize better in javascript JITs. It also looks prettier,
and makes more sense.
A SendStr is a string that can hold either a ~str or a &'static str.
This can be useful as an optimization when an allocation is sometimes needed but the common case is statically known.
Possible use cases include Maps with both static and owned keys, or propagating error messages across task boundaries.
SendStr implements most basic traits in a way that hides the fact that it is an enum; in particular things like order and equality are only determined by the content of the wrapped strings.
This basically reimplements #7599 and has a use case for replacing an similar type in `std::rt::logging` ( Added in #9180).

Replaced std::rt:logging::SendableString with SendStr
Added tests for using an SendStr as key in Hash- and Treemaps
In #8185 cross-crate condition handlers were fixed by ensuring that globals
didn't start appearing in different crates with different addressed. An
unfortunate side effect of that pull request is that constants weren't inlined
across crates (uint::bits is unknown to everything but libstd).
This commit fixes this inlining by using the `available_eternally` linkage
provided by LLVM. It partially reverts #8185, and then adds support for this
linkage type. The main caveat is that not all statics could be inlined into
other crates. Before this patch, all statics were considered "inlineable items",
but an unfortunate side effect of how we deal with `&static` and `&[static]`
means that these two cases cannot be inlined across crates. The translation of
constants was modified to propogate this condition of whether a constant
should be considered inlineable into other crates.
Closes#9036
This doesn't enable it by default yet, or include the frontend. But the tool
is pretty much done, and it'd be nice to stave off bitrot.
I couldn't get it to actually build with the Makefile though. I don't really
understand what is going on in that makefile at all. Could @graydon or
@pnkfelix lend a hand?
While they may have the same name within various scopes, this changes static
names to use path_pretty_name to append some hash information at the end of the
symbol. We're then guaranteed that each static has a unique NodeId, so this
NodeId is as the "hash" of the pretty name.
Closes#9188
Beforehand it was assumed that the standard cdecl abi was used for all extern
fns of extern crates, but this reads the abi of the extern fn type and declares
the function in the local crate with the appropriate type.
I was trying to think of how to write a test for this, but I was just drawing up blanks :(. Are there standard functions in libc which are not of the cdecl abi? If so we could try linking to them and make sure that the cal completes successfully.
Otherwise, I manually verified that the function was declared correctly by looking at the llvm assembly.
