- Successful merges: Correct a few stability attributes #47030, Disable printing of error message on file descriptor 2 on CloudABI. #47033, Use the right TLS model for CloudABI. #47110, This isn't in Rust 1.23 #47160, Remove some outdated LLVM-related code #47173, Equivalent example for ? operator #47182
- Failed merges:
As CloudABI is a capability-based runtime environment, file descriptors are the mechanism that grants rights to a process. These file descriptors may be passed into processes on startup using a utility called cloudabi-run. Unlike the POSIX shell, cloudabi-run does not follow the UNIX model where file descriptors 0, 1 and 2 represent stdin, stdout and stderr. There can be arbitrary many (or few) file descriptors that can be provided. For this reason, CloudABI's C library also doesn't define STD*_FILENO. liblibc should also not declare these. Disable the code in liballoc_system that tries to print error messages over file descriptor 2. For now, let's keep this function quiet. We'll see if we can think of some other way to log this in the future.
After rust-lang#47089 lands, CloudABI will no longer be considered UNIX. We need to pick the right allocator flavour now.
CloudABI doesn't do dynamic linking. For this reason, there is no need to handle any other TLS model than local-exec. CloudABI's C library doesn't provide a __tls_get_addr() function to do Dynamic TLS. By forcing local-exec to be used here, we ensure that we don't generate function calls to __tls_get_addr().
The function was added as a wrapper to handle compatibility with older LLVM versions that we no longer support, so it can be removed. Refs rust-lang#46437
The example with the ? operator was missing file.write_all
Correct a few stability attributes * The extra impls for `ManuallyDrop` were added in rust-lang#44310 which was only stabilised in 1.22.0. * The impls for `SliceIndex` were stabilised in rust-lang#43373 but as `RangeInclusive` and `RangeToInclusive` are still unstable the impls should remain unstable. * The `From` impls for atomic integers were added in rust-lang#45610 but most atomic integers are still unstable. * The `shared_from_slice2` impls were added in rust-lang#45990 but they won't be stable until 1.24.0. * The `Mutex` and `RwLock` impls were added in rust-lang#46082 but won't be stable until 1.24.0.

Use the right TLS model for CloudABI. CloudABI doesn't do dynamic linking. For this reason, there is no need to handle any other TLS model than local-exec.

…lexcrichton This isn't in Rust 1.23 r? @alexcrichton
Remove some outdated LLVM-related code Ticks two boxes on rust-lang#46437
Equivalent example for ? operator The example with the ? operator in the documentation for try! macro was missing file.write_all. Now all three examples are consistent.
