ca94c75c52 Auto merge of #44220 - kennytm:fix-44216-instance-plus-max-duration-should-panic, r=alexcrichton
Properly detect overflow in Instance ± Duration.

Fix #44216.
Fix #42622

The computation `Instant::now() + Duration::from_secs(u64::max_value())` now panics. The call `receiver.recv_timeout(Duration::from_secs(u64::max_value()))`, which involves such time addition, will also panic.

The reason #44216 arises is because of an unchecked cast from `u64` to `i64`, making the duration equivalent to -1 second.

Note that the current implementation is over-conservative, since e.g. (-2⁶²) + (2⁶³) is perfectly fine for an `i64`, yet this is rejected because (2⁶³) overflows the `i64`.

Use memalign instead of posix_memalign for Solaris

As pointed out in https://github.com/rust-lang/libc/commit/deb61c8,
Solaris 10 does not support posix_memalign.
Use memalign for all Solaris versions instead.
With this change applied I am able to cross-build rustc for Solaris 10.

Expect pipe symbol after closure parameter list

Fixes #44021.

---

Originally, the parser just called `bump` to discard following token after parsing closure parameter list, because it assumes `|` is following. However, the following code breaks the assumption:

```rust
struct MyStruct;
impl MyStruct {
   fn f() {|x, y}
}
```

Here, the parameter list is `x, y` and the following token is `}`. The parser discards `}`, and then we have a curly bracket mismatch.

Indeed, this code has a syntax error. On current nightly, the compiler emits an syntax error, but with incorrect message and span, followed by an ICE.

```
error: expected expression, found `}`
 --> 44021.rs:4:1
  |
4 | }
  | ^

error: internal compiler error: unexpected panic
```

Even worse, on current stable(1.20.0), the compiler falls into an infinite loop.

This pull request fixes this problem. Now the compiler emits correct error message and span, and does not ICE.

```
error: expected one of `:`, `@`, or `|`, found `}`
 --> 44021.rs:3:20
  |
3 |     fn foo() {|x, y}
  |                    ^ expected one of `:`, `@`, or `|` here
```

Use rvalue promotion to 'static instead of static items.

Fixes #44240. Among other things, in crates that do a lot of formatting, this could reduce the number of items, although I haven't measured the performance benefits. If there's a codegen slowdown, that should IMO be solved by caching the output of miri, *not* by using `static`.

rustbuild: Switch back to using hard links

The `copy` function historically in rustbuild used hard links to speed up the
copy operations that it does. This logic was backed out, however, in #39518 due
to a bug that only showed up on Windows, described in #39504. The cause
described in #39504 happened because Cargo, on a fresh build, would overwrite
the previous artifacts with new hard links that Cargo itself manages.

This behavior in Cargo was fixed in rust-lang/cargo#4390 where it no longer
should overwrite files on fresh builds, opportunistically leaving the filesystem
intact and not touching it.

Hopefully this can help speed up local builds by doing fewer copies all over the
place!

Add libbacktrace support for Apple platforms (resubmitted)

Resubmitting #43422 rebased on the current master (cc @JohnColanduoni).

I have added an additional commit to fallback to `dladdr`-based `resolve_symbol` if `libbacktrace` returns `None`, otherwise the stack trace will be full of `<unknown>` when you forget to pass the `-g` flag (actually it seems — at least on macOS — the `dladdr` symbol is more accurate than the `libbacktrace` one).

dee6d0f62e Auto merge of #44269 - nikomatsakis:issue-43613-limit-cache-obligations, r=arielb1
limit and clear cache obligations opportunistically

Keeping **all** the obligations for every projection is wasteful of
memory and compilation time. We only really care about those
subobligations that may inform the result of the projection (i.e., may
help to resolve any inference variables that appear within).
Therefore, we can clear the subobligations from the cache that don't
potentially affect the result of the projection. On every cache hit,
we also take the opportunity to check if the type variables have been
resolved *yet* and, if so, clear out the pending obligations.

Fixes #43613.

r? @arielb1

NB -- not sure how to test for this. Probably we should add the #43613 test case to perf.
