1b06375034 Auto merge of #39176 - CartesianDaemon:master, r=frewsxcv
Use fs::symlink_metadata in doc for is_symlink

fs::metadata() follows symlinks so is_symlink() will always return
false. Use symlink_metadata instead in the example in the
documentation.

See issue #39088.

syntax: remove abi::Os and abi::Architecture

They're long dead since the switch to flexible targets, but was not removed like their consumers were. Interesting they even got maintained by various porters out there!

Technically [syntax-breaking] as they're public API, but since they're unused in the compiler, the potential breakage IMO should be minimal.

Document that `Metadata` can be obtained from `symlink_metadata`

When retrieving the information about a syslink (specifically, when invoking `Metadata::is_symlink`) you generally want the `syslink_metadata`. It would be natural to point at both options to retrieve a `Metadata` value, as they are both appropriate (for different use cases).

Fix rustbuild to work with --libdir.

Similar to the makefiles, pass CFG_LIBDIR_RELATIVE to cargo when building
rustc in stages > 0.  This tells rustc to check the different directory.

I'm not sure how you want this handled in the toml system (my distribution, Gentoo, uses configure still).  I have a feeling the system needs a rework anyways for rustbuild.  If there is some discussion that needs to happen, could you merge this in the mean time?  I'd be happy to help transition this to a better method.

633f38ae99 Auto merge of #39086 - aidanhs:aphs-local-rebuild-no-jemalloc, r=alexcrichton
Make rustbuild force_alloc_system rather than relying on stage0

This 'fixes' jemalloc-less local rebuilds, where we tell cargo that we're actually stage1 (this only fixes the rustbuild path, since I wasn't enthusiastic to dive into the makefiles).

There should be one effect from this PR: `--enable-local-rebuild --disable-jemalloc` will successfully build a stage0 std (rather than erroring). Ideally I think it'd be nice to specify an allocator preference in Cargo.toml/cargo command line (used when an allocator must be picked i.e. dylibs, not rlibs), but since that's not possible we can make do with a force_alloc_system feature. Sadly this locks you into a single allocator in the build libstd, making any eventual implementation of #38575 not quite right in this edge case, but clearly not many people exercise the combination of these two flags.

This PR is also a substitute for #37975 I think. The crucial difference is that the feature name here is distinct from the jemalloc feature (reused in the previous PR) - we don't want someone to be forced into alloc_system just for disabling jemalloc!

Fixes #39054

travis: Get an emscripten builder online

This commit adds a new entry to the Travis matrix which will execute emscripten

passing on emscripten, such as:

* Ignoring i128/u128 tests as they're presumably just not working (didn't
  investigate as to why)
* Disabling a few process tests (not working on emscripten)
* Ignore some num tests in libstd (#39119)
* Fix some warnings when compiling

This is groundwork for efficiently parsing attribute proc macro invocations, bang macro invocations, and `TokenStream`-based attributes and fragment matchers.

configuration for a newer OSX image was lost as LLDB has reverted itself back to
350. This fix appeared to work for the libc crate so let's see if we can

This is a target that we're shipping today, so this commit adds this matrix

travis: Expand the `cross` linux image

This expands the `cross` travis matrix entry with a few more targets that our

* arm-unknown-linux-musleabi
* arm-unknown-linux-musleabihf
* armv7-unknown-linux-musleabihf
* mips-unknown-linux-musl
* mipsel-unknown-linux-musl

This commit doesn't compile custom toolchains like our current cross-image does,
but instead compiles musl manually and then compiles libunwind manually (like
x86_64) for use for the ARM targets and just uses openwrt toolchains for the
mips targets.

Implement `#[proc_macro_attribute]`

This implements `#[proc_macro_attribute]` as described in https://github.com/rust-lang/rfcs/pull/1566

The following major (hopefully non-breaking) changes are included:

* Refactor `proc_macro::TokenStream` to use `syntax::tokenstream::TokenStream`.
    * `proc_macro::tokenstream::TokenStream` no longer emits newlines between items, this can be trivially restored if desired
    * `proc_macro::TokenStream::from_str` does not try to parse an item anymore, moved to `impl MultiItemModifier for CustomDerive` with more informative error message

* Implement `#[proc_macro_attribute]`, which expects functions of the kind `fn(TokenStream, TokenStream) -> TokenStream`
    * Reactivated `#![feature(proc_macro)]` and gated `#[proc_macro_attribute]` under it
    * `#![feature(proc_macro)]` and `#![feature(custom_attribute)]` are mutually exclusive
    * adding `#![feature(proc_macro)]` makes the expansion pass assume that any attributes that are not built-in, or introduced by existing syntax extensions, are proc-macro attributes

* Fix `feature_gate::find_lang_feature_issue()` to not use `unwrap()`

    * This change wasn't necessary for this PR, but it helped debugging a problem where I was using the wrong feature string.

* Move "completed feature gate checking" pass to after "name resolution" pass

    * This was necessary for proper feature-gating of `#[proc_macro_attribute]` invocations when the `proc_macro` feature flag isn't set.
