This applies the same fix as added in 595d5b2f which is to just compile all
valgrind tests statically instead of dynamically. It looks like this is a
resurgence of either #30383 or #31328 in some weird fashion.
I'm not actually sure what's going on with the bots, and it's unclear whether
this is a valgrind bug or a libstd bug, but for now let's just get things
landing again.
Closes#30383
It's unclear to me whether this test failing under valgrind is actually legit.
The test only fails in valgrind when everything is dynamically linked, and it
appears to work when statically linked.
For now just add the `// no-prefer-dynamic` directive and let's just chalk it up
to a weird valgrind issue.
Closes#31328
I think I didn't run tests properly - my second call to
select_all_obligations_or_error has made 3 tests fail. However, this is
just an error message change - integer fallback never worked with casts.
Many of the modifications putting in `Box::new` calls also include a
pointer to Issue 22405, which tracks going back to `box <expr>` if
possible in the future.
(Still tried to use `Box<_>` where it sufficed; thus some tests still
have `box_syntax` enabled, as they use a mix of `box` and `Box::new`.)
Precursor for overloaded-`box` and placement-`in`; see Issue 22181.
This is an implementation of RFC 899 and adds stdio functionality to the new
`std::io` module. Details of the API can be found on the RFC, but from a high
level:
* `io::{stdin, stdout, stderr}` constructors are now available. There are also
`*_raw` variants for unbuffered and unlocked access.
* All handles are globally shared (excluding raw variants).
* The stderr handle is no longer buffered.
* All handles can be explicitly locked (excluding the raw variants).
The `print!` and `println!` machinery has not yet been hooked up to these
streams just yet. The `std::fmt::output` module has also not yet been
implemented as part of this commit.
