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
- Now "make check-stage2-T-aarch64-linux-android-H-x86_64-unknown-linux-gnu" works (#21773)
- Fix & enable debuginfo tests for android (#10381)
- Fix & enable more tests for android (both for arm/aarch64)
- Enable many already-pass tests on android (both for arm/aarch64)
