…=gnzlbg libtest: add --show-output flag to print stdout of successful tests This pull request adds a new flag `--show-output` for tests to show the output of successful tests. For most formatters this was already supported just not exposed via the CLI (apparently only used by `librustdoc`). I've also added support for this option in the JSON formatter. This kind of fixes rust-lang#54669 which wants `--format json` to work with `--nocapture`, which is... well, impossible. What this issue really calls for is `--show-output` as implemented here.
Fixed floating point issue with asinh function This should fixes rust-lang#63271 , in which `asinh(-0.0)` returns `0.0` instead of `-0.0`. according to @nagisa > > > IEEE-754 (2008), section 9.2.1: > > > For the functions expm1, exp2m1, exp10m1, logp1, log2p1, log10p1, sin, tan, sinPi, atanPi, asin, atan, sinh, tanh, asinh, and atanh, f(+0) is +0 and f(−0) is −0 with no exception. > > and > > > sinh(±∞) and asinh(±∞) are ±∞ with no exception. After ensuring that the function `asinh` is the only function affected (functions like `sin`, `sinh` are all based on `cmath` library or `llvm` intrinsics), and that `atanh` always gives the correct result. The only function to modify is `asinh`.
Propagate spans and attributes from proc macro definitions Thanks to rust-lang#63269 we now have spans and attributes from proc macro definitions available in metadata. However, that PR didn't actually put them into use! This PR finishes that work. Attributes `rustc_macro_transparency`, `allow_internal_unstable`, `allow_internal_unsafe`, `local_inner_macros`, `rustc_builtin_macro`, `stable`, `unstable`, `rustc_deprecated`, `deprecated` now have effect when applied to proc macro definition functions. From those attributes only `deprecated` is both stable and supposed to be used in new code. (`#![staged_api]` still cannot be used in proc macro crates for unrelated reasons though.) `Span::def_site` from the proc macro API now returns the correct location of the proc macro definition. Also, I made a mistake in rust-lang#63269 (comment), loaded proc macros didn't actually use the resolver cache. This PR fixes the caching issue, now proc macros go through the `Resolver::macro_map` cache as well. (Also, the first commit turns `proc_macro::quote` into a regular built-in macro to reduce the number of places where `SyntaxExtension`s need to be manually created.)

Pkgsrc changes:
* Remove patch which no longer applies (but what about RPATH?)
* Adapt a few patches to changed files upstream.
Upstream changes:
Version 1.39.0 (2019-11-07)
===========================
Language
--------
- [You can now create `async` functions and blocks with `async fn`,
`async move {}`, and `async {}` respectively, and you can now call
`.await` on async expressions.][63209]
- [You can now use certain attributes on function, closure, and function
pointer parameters.][64010] These attributes include `cfg`, `cfg_attr`,
`allow`, `warn`, `deny`, `forbid` as well as inert helper attributes used
by procedural macro attributes applied to items. e.g.
```rust
fn len(
#[cfg(windows)] slice: &[u16],
#[cfg(not(windows))] slice: &[u8],
) -> usize {
slice.len()
}
```
- [You can now take shared references to bind-by-move patterns in the
`if` guards of `match` arms.][63118] e.g.
```rust
fn main() {
let array: Box<[u8; 4]> = Box::new([1, 2, 3, 4]);
match array {
nums
// ---- `nums` is bound by move.
if nums.iter().sum::<u8>() == 10
// ^------ `.iter()` implicitly takes a reference to `nums`.
=> {
drop(nums);
// ----------- Legal as `nums` was bound by move and so we have ownership.
}
_ => unreachable!(),
}
}
```
Compiler
--------
- [Added tier 3\* support for the `i686-unknown-uefi` target.][64334]
- [Added tier 3 support for the `sparc64-unknown-openbsd` target.][63595]
- [rustc will now trim code snippets in diagnostics to fit in your terminal.]
[63402] **Note** Cargo currently doesn't use this feature. Refer to
[cargo#7315][cargo/7315] to track this feature's progress.
- [You can now pass `--show-output` argument to test binaries to print the
output of successful tests.][62600]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [`Vec::new` and `String::new` are now `const` functions.][64028]
- [`LinkedList::new` is now a `const` function.][63684]
- [`str::len`, `[T]::len` and `str::as_bytes` are now `const` functions.][63770]
- [The `abs`, `wrapping_abs`, and `overflowing_abs` numeric functions are
now `const`.][63786]
Stabilized APIs
---------------
- [`Pin::into_inner`]
- [`Instant::checked_duration_since`]
- [`Instant::saturating_duration_since`]
Cargo
-----
- [You can now publish git dependencies if supplied with a `version`.]
[cargo/7237]
- [The `--all` flag has been renamed to `--workspace`.][cargo/7241] Using
`--all` is now deprecated.
Misc
----
- [You can now pass `-Clinker` to rustdoc to control the linker used
for compiling doctests.][63834]
Compatibility Notes
-------------------
- [Code that was previously accepted by the old borrow checker, but rejected by
the NLL borrow checker is now a hard error in Rust 2018.][63565] This was
previously a warning, and will also become a hard error in the Rust 2015
edition in the 1.40.0 release.
- [`rustdoc` now requires `rustc` to be installed and in the same directory to
run tests.][63827] This should improve performance when running a large
amount of doctests.
- [The `try!` macro will now issue a deprecation warning.][62672] It is
recommended to use the `?` operator instead.
- [`asinh(-0.0)` now correctly returns `-0.0`.][63698] Previously this
returned `0.0`.
