Remove unused methods on the private Wtf8 type

The type and its direct parent module are `pub`, but they’re not reachable outside of std

std: Minimize size of panicking on wasm

2018-04-13T14:03:00+00:00

This commit applies a few code size optimizations for the wasm target to the standard library, namely around panics. We notably know that in most configurations it's impossible for us to print anything in wasm32-unknown-unknown so we can skip larger portions of panicking that are otherwise simply informative. This allows us to get quite a nice size reduction. Finally we can also tweak where the allocation happens for the `Box` that we panic with. By only allocating once unwinding starts we can reduce the size of a panicking wasm module from 44k to 350 bytes.

Import the `alloc` crate as `alloc_crate` in std

Auto merge of #48575 - ishitatsuyuki:unix-no-thread, r=alexcrichton

2018-04-04T06:19:40+00:00

rustc_driver: get rid of the extra thread **Do not rollup** We can alter the stack size afterwards on Unix. Having a separate thread causes poor debugging experience when interrupting with signals. I have to get the backtrace of the all thread, as the main thread is waiting to join doing nothing else. This patch allows me to just run `bt` to get the desired backtrace.

Implement `shrink_to` method on collections

Command: Support posix_spawn() on FreeBSD/OSX/GNU Linux

Deprecate the AsciiExt trait in favor of inherent methods

2018-03-21T16:54:33+00:00

The trait and some of its methods are stable and will remain. Some of the newer methods are unstable and can be removed later. Fixes https://github.com/rust-lang/rust/issues/39658

Simplify PATH key comparison

2018-03-19T23:15:26+00:00

Don't use posix_spawn() if PATH was modified in the environment.

2018-03-19T22:40:09+00:00

The expected behavior is that the environment's PATH should be used to find the process. posix_spawn() could be used if we iterated PATH to search for the binary to execute. For now just skip posix_spawn() if PATH is modified.
