This will allow more error checking, resilient slicing, and occasionally
other useful capabilities.
Step 1 of <rdar://problem/11940897>
Swift SVN r20036
This addresses or improves several existing TC perf bugs (rdar://problem/15933674, rdar://problem/17110608, rdar://problem/17240816, rdar://problem/17244974), and seems to speed up our unit test runs by ~5%. (On my MacBook Pro, total average execution time is reduced from 557.28s to 531.89s.)
Swift SVN r19939
modifiers and with the func implementations of the operators. This resolves the rest of:
<rdar://problem/17527000> change operator declarations from "operator prefix" to "prefix operator" & make operator a keyword
Swift SVN r19931
eliminating the @'s from them when used on func's. This is progress towards
<rdar://problem/17527000> change operator declarations from "operator prefix" to "prefix operator" & make operator a keyword
This also consolidates rejection of custom operator definitions into one
place and makes it consistent, and adds postfix "?" to the list of rejected
operators.
This also changes the demangler to demangle weak/inout/postfix and related things
without the @.
Swift SVN r19929
When the Index type of a Range is Comparable, we can reject invalid
ranges at their formation.
It might be worth injecting some checkability concept into ForwardIndex
so that even in generic contexts where Comparability is unknown, we can
do this same check in the Range constructor.
Also, remove pattern matching support for Ranges of RandomAccessIndex,
as that is covered by Interval.
Fixes <rdar://problem/16254937> (#Seed 4: Ranges with negative strides
are broken) to the extent possible (it's still possible to form an
invalid Range of indices that are not Comparable)
Fixes <rdar://problem/17164391> (Swift: Using ranges in for in for
counting down, causes the loop to go inifinely)
Fixes <rdar://problem/17580871> (Swift: Closed range with negative
endpoint excludes that endpoint)
Swift SVN r19903
This allows 0.0..<10.3 and 0.1...4.4 to work properly in pattern
matching.
Fixes <rdar://problem/12016900> (#Seed 4: add a "contains" method to the
range types) by making "contains" available on Interval
Addresses <rdar://problem/16254937> (#Seed 4: Ranges with negative
strides are broken) by making the formation of an invalid Interval a
runtime error.
Fixes <rdar://problem/16304317> (Range<T> has limited awesomeness: it is
restricted to types that conform to ForwardIndex)
Fixes <rdar://problem/16736924> (#Seed 4: Enable range inclusion pattern
matching for all types that conform to Equatable and Comparable)
Addresses <rdar://problem/16846325> (#Seed 4: Introduce index range) by
distinguishing Range (which operates on indices) from Interval
Fixes <rdar://problem/17051263> (Pattern-matching a Double range with an
infinite endpoint triggers an assertion failure)
Fixes <rdar://problem/17051271> (#Seed 4: Pattern-matching Double ranges
excludes fractional values)
Addresses <rdar://problem/17171420> (Separate types for closed and
half-open ranges)
Swift SVN r19900
This only tackles the protocol case (<rdar://problem/17510790>); it
does not yet generalize to an arbitrary "class" requirement on either
existentials or generics.
Swift SVN r19896
Mechanically add "Type" to the end of any protocol names that don't end
in "Type," "ible," or "able." Also, drop "Type" from the end of any
associated type names, except for those of the *LiteralConvertible
protocols.
There are obvious improvements to make in some of these names, which can
be handled with separate commits.
Fixes <rdar://problem/17165920> Protocols `Integer` etc should get
uglier names.
Swift SVN r19883
native Dictionary storage and adopt it if KeyType and ValueType match
exactly
This was the last missing piece to allow Dictionary to round-trip
thorough objc entrypoints of Swift methods in O(1).
Fixes rdar://17556319, partially fixes rdar://17010353
Swift SVN r19873
types to NSDictionary, perform bridging operation in O(1), and defer
bridging of the contents until the NSDictionary is accessed
There is no cache for bridged keys and values; the Swift NSDictionary
will return values with different pointer values when a given key is
repeatedly accessed.
Part of rdar://17556319
Does not fix the O(N) performance of objc thunks, because Dictionary is
not recognizing its own native storage when bridging from Objective-C.
This tracked by rdar://17010353
Swift SVN r19853
1) Add an ObjCObject disposition that tells us this Mirror is reflecting upon an ObjC-imported type
2) Change the default summary of _ClassMirror and _StructMirror to be the mangled typename, with no children count
Swift SVN r19817
ArrayBuffer
ArrayBufferType
ContiguousArrayBuffer
ContiguousArrayStorage
IndirectArrayBuffer
SliceBuffer
Unfortunately, can not remove 'public' from them since they are used by
Foundation overlay in bridging code.
Swift SVN r19810
That functionality is now covered by the stride() functions for
Range<T:RandomAccessIndex>, and probably shouldn't be used for ranges of
lesser Index protocols anyway.
Swift SVN r19803
Sliceable is a totally non-critical protocol and Range slicing wasn't
even being tested. Along with r19771, fixes <rdar://problem/16363898>
Swift SVN r19775
This horrible hack prevents the user from indexing Range<I>, for all
integer types I, outside of a generic context. This seems to be the
best we can do to prevent confusion given the current language.
Addresses <rdar://problem/16363898>
Unfortunately, I can't make this work for slicing ranges yet.
Swift SVN r19771
rely on NSDictionary.allKeys, it leaves the array of keys on the
autorelease pool. Not very bad, but it is better if we can avoid it.
rdar://17604820
Swift SVN r19724
The driver option -i now requires an input file as argument, and any
options after the input file will be treated as arguments to the
interpretted file.
This also renames the frontend option to -interpret, since it is parsed
as a flag, unlike -i. We could support -interpret in the driver if we
wanted, which would allow us to use --, but wouldn't work with shebang
scripts. For now, it's frontend-only.
Swift SVN r19718
Previously, bridged value types and their corresponding Objective-C
classes allow inter-conversion via a number of user-defined conversion
functions in the Foundation module. Instead, make this a general
feature of the type checker so we can reason about it more
directly. Fixes <rdar://problem/16956098> and
<rdar://problem/17134986>, and eliminates 11 (half) of the
__conversion functions from the standard library and overlays.
A few notes:
- The XCTest changes are because a String can no longer directly
conform to CVarArg: this is a Good Thing (TM), because it should be
ambiguous: did you mean to pass it as an NSString or a C string?
- The Objective-C representations for the bridged collections are
hard-coded in the type checker. This is unfortunate and can be
remedied by adding another associated type to the
_BridgedToObjectiveC protocol.
