On my system, when the processor is already loaded, and I try to run the test suite, e.g. compile-fail/dep-graph-assoc-type-trans.rs fails because of undecodable JSON. Running the compiler manually, I can see that the dep graph thread panics (and puts non-JSON on stderr) while `send`ing on `swap_out`, presumably because the other end has already quit. I think that in this case, we can just gracefully exit the thread.
Also move the "Thread type" section down a bit, since it is not so important anymore. Fixes: rust-lang#33321
The changed line makes it look like `unsafe` is allowed, but the first statement of `parse_item_foreign_fn` is: `self.expect_keyword(keywords::Fn)?;` So we get the strange "expected one of `fn`, `pub`, `static`, or `unsafe`, found `unsafe`". Fixes: rust-lang#27361
Broke up long lines in E0506 Trimmed E0506 comment to be under max line width Added function example to E0506 Changed example of erroneous code wording on E0506
Removed unnecessary use of threads from E0504 Cleaned up line ending on E0504 Added more examples for E0504 Changed to erroneous code wording Switched Rc example to thread/Arc example Added comments describing why errors no longer occur
We will no longer use `ccache` in the makefiles for our local dependencies like miniz, but they're so small anyway it doesn't really matter. Closes rust-lang#33285
The definition of this value recently changed slightly. It no longer corresponds directly to the target triple. Also shuffled things around to make the order of cfg descriptions more logical and added text related them to the target triple. cc rust-lang#33403
Since these impls can be scattered around quite a bit, it is nice to be able to jump to the location where individual methods and trait impls are defined. Fixes: rust-lang#30416
This should be `have` instead of `has`.

…tsakis dep_graph: avoid panicking in thread when channel closed On my system, when the processor is already loaded, and I try to run the test suite, e.g. compile-fail/dep-graph-assoc-type-trans.rs fails because of undecodable JSON. Running the compiler manually, I can see that the dep graph thread panics (and puts non-JSON on stderr) while `send`ing on `swap_out`, presumably because the other end has already quit. I think that in this case, we can just gracefully exit the thread.
…nkfelix mk: Fix building with --enable-ccache We will no longer use `ccache` in the makefiles for our local dependencies like miniz, but they're so small anyway it doesn't really matter. Closes rust-lang#33285
…Gomez std::thread docs: spawn() does not return a Thread anymore Also move the "Thread type" section down a bit, since it is not so important anymore. Fixes: rust-lang#33321
parser: do not try to continue with `unsafe` on foreign fns The changed line makes it look like `unsafe` is allowed, but the first statement of `parse_item_foreign_fn` is: ``` self.expect_keyword(keywords::Fn)?; ``` So we get the strange "expected one of `fn`, `pub`, `static`, or `unsafe`, found `unsafe`". Fixes: rust-lang#27361
rustdoc: add "src" links to individual impls Since these impls can be scattered around quite a bit, it is nice to be able to jump to the location where individual methods and trait impls are defined. NOTE: this needs an update to the CSS, which I'd like to leave for whoever is the "rustdoc frontend champion". The new [src] links are currently too large and bold. Also, the interaction with the "since version X" annotations is not good. Fixes: rust-lang#30416

…Manishearth Replace copy-pasted variable name with relevant one
errors in the doc
Remove rust flags from doc block Fixes rust-lang#33405 r? @Manishearth
Add detailed error explanation for E0389 Part of rust-lang#32777
…bnik Add an example to Wrapping's documentation. Such an example would have helped me understand `Wrapping` quicker. r? @steveklabnik
[Doc] Default cpu is "generic" (and not "default") See [line 305](/~https://github.com/phil-opp/rust/blob/a22ca2872ef6782306012e6817dc4b8b778c43e9/src/librustc_back/target/mod.rs#L305).
doc: Update reference with better description of target_env The definition of this value recently changed slightly. It no longer corresponds directly to the target triple. Also shuffled things around to make the order of cfg descriptions more logical and added text related them to the target triple. cc rust-lang#33403
Fix some some duplicate words.
doc: make RFC references consistent Always add a space and end sentence with a full stop.
doc: trim some needless code
…eGomez Fix Typo in Barrier::wait documentation This should be `have` instead of `has`.
Indicate struct names are code-like in doc-comment.
