60299d75e2 rollup merge of #19282: steveklabnik/remove_grammar
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.

985acfdb67 Merge libsync into libstd
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:

[breaking-change]

However, all uses of `libsync` should be able to reroute through
`std::sync` and `std::comm` instead.

f90471e4e3 rollup merge of #19161: jmesmon/mk-fixes
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.

12749fc8ec mk/rt: use CFG_LLVM_TARGET instead of plain target when calling llc
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

f71b852d38 rollup merge of #19103: huonw/literal-suffixes
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.

cbdaf2ebc7 rollup merge of #18903: steveklabnik/error_handling_guide
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.

600cec1cd8 mk/rt/jemalloc: pass CFG_GCCISH_CFLAGS inside CC instead of passing CFG_CFLAGS in EXTRA_CFLAGS
- 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.

7c36336c6f mk: Fix configuration of version commit information
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.

b39f1dcba0 Remove rlibc from the distribution
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.

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

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.

6b130e3dd9 Implement flexible target specification
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
x86_64-pc-windows-gnu.

The iOS target has been renamed from arm-apple-ios to arm-apple-darwin.

A complete list of the targets we accept now:

arm-apple-darwin
arm-linux-androideabi
arm-unknown-linux-gnueabi
arm-unknown-linux-gnueabihf

i686-apple-darwin
i686-pc-windows-gnu
i686-unknown-freebsd

b8e7c4fcb9 mk: Clean just one llvm build at a time. Closes #17852
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.

c245c5bbad enable parallel codegen by default
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.
