fix(sys/hermit): remove obsolete network initialization This function does not exist as of hermit-sys 0.4.1 ([`e38f246`]). Once std does not call this function, we can remove it entirely. CC: `@stlankes` [`e38f246`]: https://github.com/hermitcore/hermit-rs/commit/e38f246e046c3ad50bd2f5e33d8d810d33891cbd#diff-a9b7fa816defab285f0d4fe69d4df4a0cbbcf1c89913000df3273aded949f257R10

Add ability to spawn Windows process with Proc Thread Attributes | Take 2 This is the second attempt to merge pull request #88193 into the standard library. This PR implements the ability to add arbitrary attributes to a command on Windows targets using a new `raw_attribute` method on the [`CommandExt`](https://doc.rust-lang.org/stable/std/os/windows/process/trait.CommandExt.html) trait. `@TyPR124` and my main motivation behind adding this feature is to enable the support of pseudo terminals in the std library, but there are many more applications. A good starting point to get into this topic is to head over to the [`Win32 API documentation`](https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-updateprocthreadattribute).

2023-08-26wasi: round up the size for `aligned_alloc`Josh Stone-1/+5
C11 `aligned_alloc` requires that the size be a multiple of the alignment. This is enforced in the wasi-libc emmalloc implementation, which always returns NULL if the size is not a multiple. (The default `MALLOC_IMPL=dlmalloc` does not currently check this.)
2023-08-26Auto merge of #115228 - saethlin:is-interrupted, r=thomccbors-0/+46
Add a new helper to avoid calling io::Error::kind On `cfg(unix)`, `Error::kind` emits an enormous jump table that LLVM seems unable to optimize out. I don't really understand why, but see for yourself: https://godbolt.org/z/17hY496KG This change lets us check for `ErrorKind::Interrupted` without going through a big match. I've checked the codegen locally, and it has the desired effect on the codegen for `BufReader::read_exact`.

2023-08-25Added option to set ProcThreadAttributes for Windows processesMichael van Straten-2/+152
This implements the ability to add arbitrary attributes to a command on Windows targets using a new `raw_attribute` method on the [`CommandExt`](https://doc.rust-lang.org/stable/std/os/windows/process/trait.CommandExt.html) trait. Setting these attributes provides extended configuration options for Windows processes. Co-authored-by: Tyler Ruckinger <t.ruckinger@gmail.com>

2023-08-22std: xous: add support for locksSean Cross-1/+306
Add support for Condvar, Mutex, and RWLock. These are all backed by the ticktimer server. Signed-off-by: Sean Cross <sean@xobs.io>
2023-08-22std: xous: add thread_local_keySean Cross-1/+190
Add an implementation of thread local storage. This uses a container that is pointed to by the otherwise-unsed `$tp` register. This container is allocated on-demand, so threads that use no TLS will not allocate this extra memory. Signed-off-by: Sean Cross <sean@xobs.io>
2023-08-22std: xous: add thread supportSean Cross-1/+144
Add initial support for threads on Xous. This includes thread creation and joining. Signed-off-by: Sean Cross <sean@xobs.io>
2023-08-22std: xous: add support for timeSean Cross-1/+57
Add support for determining the current time. This connects to the ticktimer server in order to get the system uptime. Signed-off-by: Sean Cross <sean@xobs.io>
2023-08-22std: xous: add output support for stdioSean Cross-1/+131
Add support for stdout. This enables basic console printing via `println!()`. Output is written to the log server. Signed-off-by: Sean Cross <sean@xobs.io>
2023-08-22std: xous: add alloc supportSean Cross-1/+62
Basic alloc support on Xous is supported by the `dlmalloc` crate. This necessitates bumping the dlmalloc version to 0.2.4. Signed-off-by: Sean Cross <sean@xobs.io>
2023-08-22std: xous: the basics of `os`Sean Cross-1/+147
Add the basics to get the operating system running, including how to exit the operating system. Since Xous has no libc, there is no default entrypoint. Add a `_start` entrypoint to the system-specific os module. Signed-off-by: Sean Cross <sean@xobs.io>
2023-08-22libstd: add xous to libstdSean Cross-0/+47
Add the `xous` target to libstd. Currently this defers everything to the `unsupported` target. Signed-off-by: Sean Cross <sean@xobs.io>

2023-08-10Rollup merge of #114194 - thomcc:flushinline, r=cuviperMichael Goulet-0/+4
Inline trivial (noop) flush calls At work I noticed that `writer.flush()?` didn't get optimized away in cases where the flush is obviously a no-op, which I had expected (well, desired). I went through and added `#[inline]` to a bunch of cases that were obviously noops, or delegated to ones that were obviously noops. I omitted platforms I don't have access to (some tier3). I didn't do this very scientifically, in cases where it was non-obvious I left `#[inline]` off.

2023-08-09Rollup merge of #113939 - the8472:pidfd-from-child, r=Mark-SimulacrumMatthias Krüger-90/+156
open pidfd in child process and send to the parent via SOCK_SEQPACKET+CMSG This avoids using `clone3` when a pidfd is requested while still getting it in a 100% race-free manner by passing it up from the child process. This should solve most concerns in #82971
2023-08-09Auto merge of #99747 - ankane:float_gamma, r=workingjubileebors-1/+9
Add gamma function to f32 and f64 Adds the [gamma function](https://en.wikipedia.org/wiki/Gamma_function) to `f32` and `f64` (`tgamma` and `tgammaf` from C). Refs: - https://github.com/rust-lang/rfcs/issues/864 - https://github.com/rust-lang/rust/issues/18271
2023-08-08open pidfd in child process and send to the parent via SOCK_SEQPACKET+CMSGThe 8472-90/+156
This is a 100% race-free way to obtain a child's pidfd while avoiding `clone3`.
2023-08-08Rollup merge of #106425 - ijackson:exit-status-default, r=dtolnayMatthias Krüger-23/+24
Make ExitStatus implement Default And, necessarily, make it inhabited even on platforms without processes. I noticed while preparing https://github.com/rust-lang/rfcs/pull/3362 that there was no way for anyone to construct an `ExitStatus`. This would be insta-stable so needs an FCP.
