on every call. This ensures that implies bounds are reasonable
(the older code only checked that the values provided had WF types, but
we also must know that the formal types of the arguments are WF.)
warnings. It also checks more conditions than the old code. Keep the
old wf code around unchanged so that we can continue to issue errors for
the cases where we used to report errors.
As part of this, remove the where-clauses-must-reference-parameter rule,
which is easily circumvented.
`implicator`. These definitions are also in accordance with RFC 1214 (or
more so), and hence somewhat different from the implicator. This commit
also modifies the implicator to remove the older rules for projections,
which can easily trigger infinite loops.
after we check casts, because sometimes casts can influence inference,
unfortunately. We do re-run `select_all_trait_obligations` during
regionck anyhow.
This commit removes all unstable and deprecated functions in the standard
library. A release was recently cut (1.3) which makes this a good time for some
spring cleaning of the deprecated functions.
Implemented count, nth, and last in constant time for Windows, Chunks,
and ChunksMut created from a slice.
Included checks for overflow in the implementation of nth().
Also added a test for each implemented method to libcoretest.
Addresses #24214
Initial version of PR had an DerefMut implementation, which was later removed
because it may cause mutable reference aliasing.
Suggest how to implement mutability with reentrant mutex and remove the claim we
implement DerefMut.
This commit leverages the runtime support for DWARF exception info added
in #27210 to enable unwinding by default on 64-bit MSVC. This also additionally
adds a few minor fixes here and there in the test harness and such to get
`make check` entirely passing on 64-bit MSVC:
* The invocation of `maketest.py` now works with spaces/quotes in CC
* debuginfo tests are disabled on MSVC
* A link error for librustc was hacked around (see #27438)
I was not able to come up with tests that would expose this bug, as, apparently, Rust types of the args are not used for anything but debug logging.
Thanks to @luqmana for pointing this out!
LLVM might perform tail merging on the calls that initiate the unwinding
process which breaks debuginfo and therefore this test. Since tail
merging is guaranteed to break debuginfo, it should be disabled for this
test.
This allows us to restore a testcase that I had to remove earlier
because of the same problem, because back then I didn't realize that
disabling tail merging was an option.

As title :-)
Part of #24407.
r? @Manishearth
This will need merging with E0193, so probably want to delay any r+ until that goes in and I can merge myself.
See line 181: The lookup should start with the random index and iterate from there.
Also locked stdout (which makes it a bit faster on my machine). And the `make_lookup` function now uses `map` (as the TODO asked for).
Perhaps the multi-thread output from the fasta benchmark could be used to speed it up even more.
