After 8b3c67690c the `make install`
command fails if docs are not disabled through CFG_DISABLE_DOCS,
because now the `install` target uses
../../tmp/dist/$(DOC_PKG_NAME)-$(CFG_BUILD)/install.sh
In 714a2c678c the `prepare_install`
target wwas changed to conditionally depend also on the doc archive,
but did not modify `prepare_uninstall`.
Instead of explicitly depending on
dist/$(PKG_NAME)-$(CFG_BUILD).tar.gz, the `prepare_[un]install`
targets now depend on `dist-tar-bins`, which packages the appropriate
dist archives depending on the configuration.
Adds a new 'beta cycle' variable that can be appended to the '-beta' version label, e.g. '-beta1'. Changes the version label for the beta channel temporarily to 'alpha'. Changes the artifact name of the beta channel to contain the version number instead of just being called 'beta'. The beta cycle number is currently set to 1.
The impact of this is that the first alphas will be called '1.0.0-alpha1' and the artifacts will also be called '1.0.0-alpha1-*.tar.gz'. We could alternately leave out the cycle number if we are confident there will be only one alpha cycle.

This distributes docs in a separate package called rust-docs. The rust-packaging
project will combine it with Rust and Cargo into a single installer in a variety of formats.
I would like to look into some issues related to the model lexer #15883.
I stumbled upon 2 minor problems when I tried running the lexer tests:
* antlr did not put the generated files in the correct directory
* grammer/verify.rs did not work with the most recent version of rust
With these changes (and setting CLASSPATH=/usr/share/java/antlr-4.4-complete.jar:$CLASSPATH) I was able to execute the tests.
Note that I just fixed the syntax errors and added `None` as 2. argument of `Literal`. I am not sure if this is correct however. I still have to take a closer look at what verify.rs actually does. Are there any helpful pointers?
These crates are all deprecated for their rust-lang/$crate equivalents and by
generating docs we're generating broken links. The documentation for these
crates are generated out-of-tree and are managed separately, so we're not losing
the documentation altogether, just the links from the main distribution's docs.

It's quite possible that small programs don't use all of jemalloc, and building
with -ffunction-sections and -fdata-sections allows the linker (via
--gc-sections) to strip out all unused code at link time. This decreases the
size of a "hello world" executable for me from 716K to 482K with no measurable
impact on link time. After this patch jemalloc is still the largest portion of
our hello world executables, but this helps cut down on the size at least
somewhat!

In the HTML version of the documentation, it isn't rendered so might as well use the unicode representation.
Part of the problem was that putting a math unicode character wasn't

This commit merges the `rustrt` crate into `std`, undoing part of the
facade. This merger continues the paring down of the runtime system.
Code relying on the public API of `rustrt` will break; some of this API
is now available through `std::rt`, but is likely to change and/or be
removed very soon.

This is a work in progress, but this should get *extensive* review, so I'm putting it up early and often.
This is the start of a draft of the new 'ownership guide,' which explains ownership, borrowing, etc. I'm feeling better about this framing than last time's, but we'll see.
I stumbled across this today, and it's not really working. It's been around for a very, very long time, and seems to be based on stuff we don't even have anymore.
I asked in `#rust-internals`, and @cmr said we should just kill it, so here I am. :) I don't think that anything else uses Java, but maybe I missed something.
And if this _isn't_ what we want, I'm fine with closing too. Just some housekeeping.
This patch merges the `libsync` crate into `libstd`, undoing part of the
facade. This is in preparation for ultimately merging `librustrt`, as
well as the upcoming rewrite of `sync`.
Because this removes the `libsync` crate, it is a:

However, all uses of `libsync` should be able to reroute through
`std::sync` and `std::comm` instead.
This is a collection of misc issues I've run into while adding bindir & libdir support that aren't really bindir & libdir specific.
While I continue to fiddle with bindir and libdir bugs, I figured these might be useful for others to have merged.
Right now we'll end up globbing them into the accepted targets and (ever worse) they will override the make variables of real target files because we `include`d everything in that directory.
As a side effect, editors get a better hint on file types.
Fixies #11671
This commit changes default relative libdir 'lib' to a relative libdir calculated using LIBDIR provided by --libdir configuration option. In case if no option was provided behavior does not change.
We add CFG_LLVM_TARGET_$(target) (which can be defined in any of the
mk/cfg/* files) and supply a default to the plain target name
CFG_LLVM_TARGET mirrors the value of llvm_target (aka llvm-target) in
the librustc_back runtime target specification.
Without this, if we we're using a non-standard host libdir, the target
bindir would not exist (and rustc would fail to write to the
non-existent directory).
If the expected rustc snapshot is not where we expect it to be,
complain and fail at that point rather than creating a empty rustc file
and continuing until we try to run it.
Futureproof Rust for fancier suffixed literals. The Rust compiler tokenises a literal followed immediately (no whitespace) by an identifier as a single token: (for example) the text sequences `"foo"bar`, `1baz` and `1u1024` are now a single token rather than the pairs `"foo"` `bar`, `1` `baz` and `1u` `1024` respectively.
The compiler rejects all such suffixes in the parser, except for the 12 numeric suffixes we have now.
I'm fairly sure this will affect very few programs, since it's not currently legal to have `<literal><identifier>` in a Rust program, except in a macro invocation. Any macro invocation relying on this behaviour can simply separate the two tokens with whitespace: `foo!("bar"baz)` becomes `foo!("bar" baz)`.
This implements [RFC 463](https://github.com/rust-lang/rfcs/blob/master/text/0463-future-proof-literal-suffixes.md), and so closes https://github.com/rust-lang/rust/issues/19088.
Now that we've done `fail` -> `panic`, I feel bringing back the error handling guide is a good idea. We had one long ago, but it was removed when conditions were removed.
This doesn't cover the new FromError stuff, but I feel like it's already useful in this state, so I'm sending this PR now.
- CFG_CFLAGS is gone (it was previously only used by jemalloc anyhow).
- CFG_JEMALLOC_CFLAGS may contain flags needed for the compiler to
function (produce a binary output).
- jemalloc's configure runs $(CC) without EXTRA_CFLAGS, and (without
this change) will fail if any flags are required for CC to work.
not in hardcoded libdir path. If there was no LIBDIR provided
during configuration fallback to hardcoded paths.

Closes#11671
Commit bec2ee77f7 started quoting paths
discovered as part of the `probe` function, which includes git. The
`make` `wildcard` function appears to be incompatible with quoted
paths so this check in the makefile now fails. Employing `wildcard`
here appears to only re-verify that git actually exists, which the
configure script already did, so I've just removed it.
Additionally, with the quoted paths the `subst` function should no
longer be needed, so I've removed it as well.
Closes#18771
1. Introduce `putpathvar` function that prints variable shell-quoted by using `%q` format specifier. This function is used within `probe` to save the result into `config.tmp`.
2. Removes search-and-replace pattern that transforms `\` into `/` as it messes up shell-quoted strings.
To make progress on #18585 we're paring down the distribution to theoretically
"only libstd", and this commit makes progress on this by removing the rlibc
crate from the distribution.
The crate has now been moved into an external cargo package located in the rust
lang organization [1]. This is a breaking change due to this removal, and
existing crates depending on `rlibc` should use the Cargo crate instead.

Right now the windows nightlies are failing because they're encountering a
linker error when producing stage3 libs. The stage3 libs aren't actually used in
general, and we primarily just want to generate a static stage3 binary, not
static stage3 dylibs.
If a dylib is being produced, the compiler will now first check to see if it can
be created entirely statically before falling back to dynamic dependencies. This
behavior can be overridden with `-C prefer-dynamic`.
Due to the alteration in behavior, this is a breaking change. Any previous users
relying on dylibs implicitly maximizing dynamic dependencies should start
passing `-C prefer-dynamic` to compilations.

Removes all target-specific knowledge from rustc. Some targets have changed
during this, but none of these should be very visible outside of
cross-compilation. The changes make our targets more consistent.
iX86-unknown-linux-gnu is now only available as i686-unknown-linux-gnu. We
used to accept any value of X greater than 1. i686 was released in 1995, and
should encompass the bare minimum of what Rust supports on x86 CPUs.
The only two windows targets are now i686-pc-windows-gnu and

When building for multiple targets, the initial 'make' invocation
always fails. The missing build stamp causes clean-llvm to be
invoked, but clean-llvm cleans *all* llvm builds. So what happens
is that 1) all llvm's are cleaned (a no-op), 2) llvm-${target1}
builds, 3) all llvm's are cleaned (deleting llvm-${target1}),
4) llvm-${target2} is built, 5) the remaining build for ${target1}
fails because llvm does not exist.
This makes the clean operation only clean the correct llvm build.
Should greatly reduce bot failures.
Enable parallel codegen (2 units) by default when --opt-level is 0 or 1. This
gives a minor speedup on large crates (~10%), with only a tiny slowdown (~2%)
for small ones (which usually build in under a second regardless). The current
default (no parallelization) is used when the user requests optimization
(--opt-level 2 or 3), and when the user has enabled LTO (which is incompatible
with parallel codegen).
This commit also changes the rust build system to use parallel codegen
when appropriate. This means codegen-units=4 for stage0 always, and
also for stage1 and stage2 when configured with --disable-optimize.
(Other settings use codegen-units=1 for stage1 and stage2, to get
maximum performance for release binaries.) The build system also sets
codegen-units=1 for compiletest tests (compiletest does its own
parallelization) and uses the same setting as stage2 for crate tests.
All of these crates have been deprecated for some time and properly live in the
rust-lang organization as cargo-based crates.

----
To reproduce issue on commit ba246100ca
it does not suffice to add just `check-build-compiletest` to
`check-secondary`; one must also ensure that `check-build-compiletest`
precedes the satisification of the `check` rule.
Otherwise hidden dependencies of `compiletest` would end up getting
satisfied when make builds `rustc` at each stage in order to
eventually run `check-stage2`.
So to handle that I moved `check-secondary` before `check` in the
`check-all` rule that bors uses, and for good measure, I also put
`check-build-compiltest` at the front of the `check-secondary` rule's
dependencies.
My understanding is that running `check-secondary` should be
relatively cheap, and thus such a reordering will not hurt bors.

Fix#17883.
compiletest needs to link to native crate, or at least the `rt` library.
