Without `_blackHole`, the optimizer may remove or make assumptions about values, which are not intended by the test.
This fixes the tests when running them in optimize mode and when OSSA modules are enabled.
This is part of rdar://140229560.
Those tests rely on lexical object lifetimes. But lifetimes are only guaranteed for "variables" but not for temporary objects.
Storing those objects in variables fixes the issue.
This fixes the tests when running them in optimize mode and when OSSA modules are enabled.
This is part of rdar://140229560.
The _StringProcessing module provides a generic, collection-based
`contains` method that performs poorly for ranges and closed ranges.
This addresses the primary issue by providing concrete overloads
for Range and ClosedRange which match the expected performance for
these operations.
This change also fixes an issue with the existing range overlap tests.
The generated `(Closed)Range.overlap` tests are ignoring the "other"
range type when generating ranges for testing, so all overlap tests
are only being run against ranges of the same type. This fixes things
so that heterogeneous testing is included.
Some editors use diagnostics from SourceKit to replace build issues. This causes issues if the diagnostics from SourceKit are formatted differently than the build issues. Make sure they are rendered the same way, removing most uses of `DiagnosticsEditorMode`.
To do so, always emit the `add stubs for conformance` note (which previously was only emitted in editor mode) and remove all `; add <something>` suffixes from notes that state which requirements are missing.

When initializing a range set with a group of overlapping, identical,
or empty ranges, the initializer can exhibit poor performance due
to removing the unneeded ranges during processing. This change uses
a partitioning scheme instead, only removing the unnecessary ranges
at the end of initialization.
Using inconsistent attributes between stdlib and tests causes
compilation errors. There are still several misuses of @_silgen_name in
tests, but leaving them as is for now to incrementally fix them.
This change introduces a new compilation target platform to the Swift compiler - visionOS.
- Changes to the compiler build infrastrucuture to support building compiler-adjacent artifacts and test suites for the new target.
- Addition of the new platform kind definition.
- Support for the new platform in language constructs such as compile-time availability annotations or runtime OS version queries.
- Utilities to read out Darwin platform SDK info containing platform mapping data.
- Utilities to support re-mapping availability annotations from iOS to visionOS (e.g. 'updateIntroducedPlatformForFallback', 'updateDeprecatedPlatformForFallback', 'updateObsoletedPlatformForFallback').
- Additional tests exercising platform-specific availability handling and availability re-mapping fallback code-path.
- Changes to existing test suite to accomodate the new platform.
* Revert "Revert count(where:)"
This reverts commit 779ea19a6a.
Now that SE-0220 has been re-accepted, this adds the `count(where:)`
Sequence method to the standard library.
These are provided for FixedWidthInteger & UnsignedInteger (the base implementation, following Knuth's Algorithm D) and SignedInteger (converting to magnitudes and calling the former). Previously no default implementations were available, requiring every type to implement these operations.
These defaults will not be optimal for large fixed-width integers, so types vending Int512 or similar integers should still provide their own implementations, but they are unconditionally available as a fallback, which simplifies the process of writing such types, and work well enough as a fallback for modest fixed-width integer types like Int64 or 32b or smaller platforms or Int128 on 64b platforms.
Additionally rework the concrete implementations to guarantee that we always trap when the quotient is not representable, and to improve performance for 64b integers on arm64_32, and added some new test coverage for these operations.

This precondition checks to make sure that the content-providing
collection isn't larger than the allocated buffer, but was preventing
using a buffer that is the exact same size as the collection.
watchOS devices can have different allocation characteristics
from other devices. This modifies the string capacity growth
tests to be more flexible about measuring the growth in
capacity, specifically when more is allocated than requested.
When called on a string that is not uniquely referenced,
`String.reserveCapacity(_:)` ignores the current capacity, using
the passed-in capacity for the size of its new storage. This can
result in an underallocation and write past the end of the new
buffer.
This fix changes the new size calculation to use the current UTF-8
count as the minimum. Non-native or non-unique strings
now allocate the requested capacity (or space enough for the
current contents, if that's larger than what's requested).

Fixes#53483
It shares many of the same values as OpenBSD (which both inherited from 4.4BSD),
and we wouldn't expect those to diverge due to the respective platforms'
bincompat goals.
