LLVM 10 includes a009a60 which will print value numbers for unnamed func args. Update these tests to be in line with the referenced clang tests.
It isn't clear to me if this is a bug or not, hence the FIXME
de-promote Duration::from_secs In rust-lang#67531, we removed the `rustc_promotable` attribute from a bunch of `Duration` methods, but not from `Duration::from_secs`. This makes the current list of promotable functions the following (courtesy of @ecstatic-morse): * `INT::min_value`, `INT::max_value` * `std::mem::size_of`, `std::mem::align_of` * `RangeInclusive::new` (backing `x..=y`) * `std::ptr::null`, `std::ptr::null_mut` * `RawWaker::new`, `RawWakerVTable::new` ??? * `Duration::from_secs` I feel like the last one stands out a bit here -- the rest are all very core language primitives, and `RawWaker` has a strong motivation for getting a `'static` vtable. But a `&'static Duration`? That seems unlikely. So I propose we no longer promote calls to `Duration::from_secs`, which is what this PR does. rust-lang#67531 saw zero regressions and I am not aware of anyone complaining that this broke their (non-cratered) code, so I consider it likely the same will be true here, but of course we'd do a crater run. See [this document](https://github.com/rust-lang/const-eval/blob/master/promotion.md) for some more background on promotion and rust-lang/const-eval#19 for some of the concerns around promoting function calls.
linker: Add a linker rerun hack for gcc versions not supporting -static-pie Which mirrors the existing `-no-pie` linker rerun hack, but the logic is a bit more elaborated in this case. If the linker (gcc or clang) errors on `-static-pie` we rerun in with `-static` instead. We must also replace CRT objects corresponding to `-static-pie` with ones corresponding to `-static` in this case. (One sanity check for CRT objects in target specs is also added as a drive-by fix.) To do in the future: refactor all linker rerun hacks into separate functions and share more code with `add_(pre,post)_link_objects`. This PR accompanies rust-lang#71804 and unblocks rust-lang#70740.

…70924, r=nikomatsakis run-make regression test for issue rust-lang#70924. Sometime after my PR rust-lang#72767 (to fix issue rust-lang#70924) landed, I realized that I *could* make a local regression test, thanks to `rustc --print sysroot`: I can make a fresh "copy" (really mostly symlinks) of the sysroot, and then modify it to recreate the terms of this bug.
…atsakis Fix codegen tests for RISC-V Some codegen tests didn't seem relevant (e.g. unsupported annotations). The RISC-V abi tests were broken by LLVM 10, c872dcf fixes that (cc: @msizanoen1) I'm not sure about skipping catch-unwind.rs and included that change here mostly as a request for comment - I can't tell if that's a bug.
…u16, r=sfackler
impl ToSocketAddrs for (String, u16)
This adds a convenience impl of `ToSocketAddrs for (String, u16)`. When authoring HTTP services it's common to take command line options for `host` and `port` and parse them into `String` and `u16` respectively. Consider the following program:
```rust
#[derive(Debug, StructOpt)]
struct Config {
host: String,
port: u16,
}
async fn main() -> io::Result<()> {
let config = Config::from_args();
let stream = TcpStream::connect((&*config.host, config.port))?; // &* is not ideal
// ...
}
```
Networking is a pretty common starting point for people new to Rust, and seeing `&*` in basic examples can be confusing. Even as someone that has experience with networking in Rust I tend to forget that `String` can't be passed directly there. Instead with this patch we can omit the `&*` conversion and pass `host` directly:
```rust
#[derive(Debug, StructOpt)]
struct Config {
host: String,
port: u16,
}
async fn main() -> io::Result<()> {
let config = Config::from_args();
let stream = TcpStream::connect((config.host, config.port))?; // no more conversions!
// ...
}
```
I think should be an easy and small ergonomics improvement for networking. Thanks!… r=Xanewok save_analysis: fix some ICEs Fixesrust-lang#73020Fixesrust-lang#73022Fixesrust-lang#73041

It's probably #73046, which I didn't see was also in the overlap. |
