Closes#15017 (Deprecate the bytes!() macro.)
Replace its usage with byte string literals, except in `bytes!()` tests.
Also add a new snapshot, to be able to use the new b"foo" syntax.
The src/etc/2014-06-rewrite-bytes-macros.py script automatically
rewrites `bytes!()` invocations into byte string literals.
Pass it filenames as arguments to generate a diff that you can inspect,
or `--apply` followed by filenames to apply the changes in place.
Diffs can be piped into `tip` or `pygmentize -l diff` for coloring.
Fixes a codegen bug which generates illegal non-terminated LLVM block
when there are wildcard pattern with guard and enum patterns in a match
expression. Also refactors the code a little.
Closes#14865
This patch consolidates and cleans up the task spawning APIs:
* Removes the problematic `future_result` method from `std::task::TaskBuilder`,
and adds a `try_future` that both spawns the task and returns a future
representing its eventual result (or failure).
* Removes the public `opts` field from `TaskBuilder`, instead adding appropriate
builder methods to configure the task.
* Adds extension traits to libgreen and libnative that add methods to
`TaskBuilder` for spawning the task as a green or native thread.
Previously, there was no way to benefit from the `TaskBuilder` functionality and
also set the scheduler to spawn within.
With this change, all task spawning scenarios are supported through the
`TaskBuilder` interface.
Closes#3725.
[breaking-change]
Define a command :Run to compile and run the current file. This supports
unnamed buffers (by writing to a temporary file). See the comment above
the command definition for notes on usage.
Define <D-r> and <D-R> mappings for :Run to make it easier to invoke in
MacVim.
Define a command :Expand to display the --pretty expanded output for the
current file. This can be configured to use different pretty types. See
the comment above the command definition for notes on usage.
Create an autoload file and put function definitions there to speed up
load time.
The nightly builds on linux have been failing over the past few days due to a
malformed LD_LIBRARY_PATH. It appears that the underlying cause is that one of
the tests, dep-info-custom, recursively invokes make but the RUSTC variable
passed down has the string "$LD_LIBRARY_PATH". This is intended to read the
host's original LD_LIBRARY_PATH, but it appears that the makefile is eagerly
expanding the "$L" to nothing, causing the original host's LD_LIBRARY_PATH to be
ignored.
This fix removes passing the string "$LD_LIBRARY_PATH" and rather expands it
eagerly to ensure that escaping doesn't happen at a later stage. I'm still not
entirely sure why the makefile is interpreting the dollar as a variable, but
this seems to fix the issue.

Teach StringReader how to emit errors for arbitrary spans, so we don't
need to modify peek_span. This allows for emitting errors without having
a &mut borrow of the StringReader.
This test was added long time ago and marked as ignored.
The same test was added later in #8485 as run-fail/issue-3907.rs,
but the old one was not deleted.
Fix#6298. Fix #13767.
This also includes some drive by fixes for some other issues, noted in the commits.
I still need to integrate regression tests for some cases that I noticed were missing from our unit test suite (i.e. things that compiling rustc exposes that should have been exposed when doing `make check-stage1`). So do not land this yet, until I get the chance to add those tests.
I just wanted to get the review process started soon, since this has been long in the coming.
thereof.)
PR 14739 injected the new message that this removes from one test
case: borrowck-vec-pattern-loan-from-mut.rs
When reviewing the test case, I was not able to convince myself that
the error message was a legitimate thing to start emitting. Niko did
not see an obvious reason for it either, so I am going to remove it
and wait for someone (maybe Cameron Zwarich) to explain to me why we
should be emitting it.
Details: in a program like:
```
type T = proc(int) -> int; /* 4 */
pub fn outer(captured /* pat 16 */: T) -> T {
(proc(x /* pat 23 */) {
((captured /* 29 */).foo((x /* 30 */)) /* 28 */)
} /* block 27 */ /* 20 */)
} /* block 19 */ /* 12 */
```
the `captured` arg is moved from the outer fn into the inner proc (id=20).
The old dataflow analysis for flowed_move_data_moves, when looking at
the inner proc, would attempt to add a kill bit for `captured` at the
end of its scope; the problem is that it thought the end of the
`captured` arg's scope was the outer fn (id=12), even though at that
point in the analysis, the `captured` arg's scope should now be
restricted to the proc itself (id=20).
This patch fixes handling of upvars so that dataflow of a fn/proc
should never attempts to add a gen or kill bit to any NodeId outside
of the current fn/proc. It accomplishes this by adding an `LpUpvar`
variant to `borrowck::LoanPath`, so for cases like `captured` above
will carry both their original `var_id`, as before, as well as the
`NodeId` for the closure that is capturing them.
As a drive-by fix to another occurrence of a similar bug that
nikomatsakis pointed out to me earlier, this also fixes
`gather_loans::compute_kill_scope` so that it computes the kill scope
of the `captured` arg to be block 27; that is, the block for the proc
itself (id=20).
(This is an updated version that generalizes the new loan path variant
to cover all upvars, and thus renamed the variant from `LpCopiedUpvar`
to just `LpUpvar`.)
Fix#6298.
This is instead of the prior approach of emulating cfg traversal
privately by traversing AST in same way).
Of special note, this removes a special case handling of `ExprParen`
that was actually injecting a bug (since it was acting like an
expression like `(*func)()` was consuming `*func` *twice*: once from
`(*func)` and again from `*func`). nikomatsakis was the first one to
point out that it might suffice to simply have the outer `ExprParen`
do the consumption of the contents (alone).
(This version has been updated to incorporate feedback from Niko's
review of PR 14873.)
1. After recursively processing an ExprWhile, need to pop loop_scopes
the same way we do for ExprLoop.
2. Proposed fix for flowgraph handling of ExprInlineAsm: we need to
represent the flow into the subexpressions of an `asm!` block.
This addresses the font lock regression introduced by the earlier pull
request #14818 - attributes are no longer be highligted inside of comments
and strings.
Also add some font lock test infrastructure and some tests for attribute
font locking and fix some minor nits.
