Building with `--target=mipsel-unknown-linux-gnu` currently results in the following errors, fixed by this PR:

These constants were added in 6f54ce9aa5 and
e8fbd1ce04 to a consts module that is behind a
gate.
I have not confirmed that these constants do indeed work on either OSX or iOS.
It appears that some of the constants may actually belong in a POSIX module,
but I didn't make these changes here because I don't have access to the POSIX
standard.
PR #24611 added these for other architectures, but missed
the `#[cfg(any(target_arch = "mips", target_arch = "mipsel"))]`
version of the module. The values are the same.
This commit modifies the standard library and its dependencies to link correctly
when built against MUSL. This primarily ensures that the right libraries are
linked against and when they're linked against they're linked against
statically.
This patch adds a `Debug` impl for `std::fs::File`.
On all platforms (Unix and Windows) it shows the file descriptor.
On Linux, it displays the path and access mode as well.
Ideally we should show the path/mode for all platforms, not just Linux,
but this will do for now.
cc #24570
This is probably more broadly applicable than these two platforms
(since it's part of the bsd4.4 standard) but that's outside my problem domain today.
If this goes well, I may submit Linux/64 support in a separate PR.
Reviewers should take a look at http://www.opensource.apple.com/source/xnu/xnu-792.17.14/bsd/sys/socket.h?txt
which defines constants for OSX. iOS uses the same header.
I release this patch under the MIT license.
Hopefully didn’t miss or mess up anything.
~~EDIT: ah, as usual, just didn’t bother running build before pushing a submit request button. Build pending.~~
The alignment field is actually a "pointer sized" type instead of always i64,
requiring that the size of the padding field is also calculated slightly
differently.
Closes#23425
To the correct MAP_NORESERVE. Every other thing is known as MAP_NORESERVE, so this is just a basic typo.
I really doubt this will break anybody's but my own code.
This separates definitions of struct stat and other typedefs between Android and Linux on ARM (Android has a non-standard one). This makes functions such as `File::metadata()` work correctly and makes one able to check file's size. All tests from std (and also run-pass: stat.rs) now pass on ARM Linux. Fixes#20007.
According to Apple's [arm64 calling convention](https://developer.apple.com/library/ios/documentation/Xcode/Conceptual/iPhoneOSABIReference/Articles/ARM64FunctionCallingConventions.html#//apple_ref/doc/uid/TP40013702-SW1) varargs always are passed
through stack. Since `open` is actually a vararg function on Darwin,
it means that older declaration caused permissions to be taken from
stack, while passed through register => it set file permissions
to garbage and it was simply impossible to read/delete files after they
were created.
They way this commit handles it is to preserve compatibility with
existing code - it simply creates a shim unsafe function so all existing
callers continue work as nothing happened.

Automatic has-same-types testing methodology can be found in #22501.
Because most of them don't work with `--pretty=typed`, compile-fail tests were manually audited.

This same source is being built in the Cargo ecosystem and hence needs to build
on stable Rust as well. This commit places the `no_std` attribute along with the
`no_std` feature behind a `cfg_attr` flag so they are not processed when
compiled on crates.io
