Makes a couple changes that support the implementation of a REPL:
* Implementation of wrapper code for LLVM ExecutionEngine API
* Fixing a change I made earlier to reset compiler state in `phase_1_[...]`
instead of `compile_input` as the latter is not used in a REPL
- Support gcc-less installation on Windows. To do so in unattended mode run:`<intaller>.exe /TYPE=compact /SILENT`.
- Do not require admin privileges to install.

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:
[breaking-change]
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.
Thanks to Jan Niklas Hasse for solution and to Alex Crichton for improvements.
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.
