* Revert "[strip -ST] Disable runtime stack trace dumping on Darwin when asserts are disabled."
This reverts commit 6bc28ff1c9.
* Bring back important fixes from the revert of 6bc28ff1c9.
* Change swift::swift_reportError to only print the backtrace in assert builds (swift::warning prints backtrace always).
The compiler pre-canonicalizes protocol composition types by minimizing constraints and sorting the remaining protocols by module + name, which ought to be globally stable within a program (assuming there aren't multiple modules with the same name, in which case we'll have bigger problems…). The compiler also statically lays out existential types according to its conception of the canonical composition ordering, so the runtime's own attempts to form a stable ordering lead to layout inconsistencies between runtime and compile-time layout, leading to crashes like SR-4477.
Register class names for NSKeyedArchiver and NSKeyedUnarchiver based on the @NSKeyedArchiveLegacy and @_staticInitializeObjCMetadata class attributes.
@NSKeyedArchiveLegacy registers a class name translation.
@_staticInitializeObjCMetadata just makes sure that the metadata of a class is instantiated.
This registration code is executed as a static initializer, like a C++ global constructor.
This commit disables runtime stack trace dumping via dladdr on Darwin when
asserts are disabled.
This stack trace dumping was added as a way to improve the ability to debug the
compiler for compiler developers. This is all well and good but having such a
feature always enabled prevents us from reducing the size of the swift standard
library by eliminating the swift nlist.

This reverts commit 25985cb764. For now,
we're trying to avoid spurious non-structural changes to the mangling,
so that the /old/ mangling doesn't appear to change. That doesn't mean
no changes at all, but we can save this one for later.
The COW existential implementation sets the existential box's
new value but fails to set the box's new type. Hijinks ensue
when the new value is later used as if it were of the old type.

Some places in this header were following the LLVM convention of:
namespace ... {
struct Foo {
};
}
and one-two places had extra indentation. I standardized the code on the LLVM
convention.
* [runtime] Fix some casts of _SwiftValue.
* Allow _SwiftValue to be cast to NSObject by yielding the box object itself.
* Failed casts from NSDictionary containing _SwiftValue should not crash.

Introduce a new runtime entry point,
`swift_objc_swift3ImplicitObjCEntrypoint`, which is called from any
Objective-C method that was generated due to `@objc` inference rules
that were removed by SE-0160. Aside from being a central place where
users can set a breakpoint to catch when this occurs, this operation
provides logging capabilities that can be enabled by setting the
environment variable SWIFT_DEBUG_IMPLICIT_OBJC_ENTRYPOINT:
SWIFT_DEBUG_IMPLICIT_OBJC_ENTRYPOINT=0 (default): do not log
SWIFT_DEBUG_IMPLICIT_OBJC_ENTRYPOINT=1: log failed messages
SWIFT_DEBUG_IMPLICIT_OBJC_ENTRYPOINT=2: log failed messages with
backtrace
SWIFT_DEBUG_IMPLICIT_OBJC_ENTRYPOINT=3: log failed messages with
backtrace and abort the process.
The log messages look something like:
***Swift runtime: entrypoint -[t.MyClass foo] generated by
implicit @objc inference is deprecated and will be removed in
Swift 4
* IRGen: Change c-o-w existential implementation functions
* initialzeBufferWith(Copy|Take)OfBuffer value witness implementation for cow existentials
Implement and use initialzeBufferWith(Copy|Take)OfBuffer value witnesses for
copy-on-write existentials.
Before we used a free standing function but the overhead of doing so was
noticable (~20-30%) on micro benchmarks.
* IRGen: Use common getCopyOutOfLineBoxPointerFunction
* Add a runtime function to conditionally make a box unique
* Fix compilation of HeapObject.cpp on i386
* Fix IRGen test case
* Fix test case for i386
Replace VariadicTuple and NonVariadicTuple with a single Tuple node.
The variadic property is now part of the tuple element and not of the whole tuple.
Adds the runtime implementation for copy-on-write existentials. This support is
enabled if SWIFT_RUNTIME_ENABLE_COW_EXISTENTIALS is defined. Focus is on
correctness -- not performance yet.
Don't use allocate/deallocate/projectBuffer witnesses for globals in cow
existential mode.
Use SWIFT_RUNTIME_ENABLE_COW_EXISTENTIALS configuration to set the default for
SILOptions.
This includes an IRGen fix to use the right projection in
emitMetatypeOfOpaqueExistential if SWIFT_RUNTIME_ENABLE_COW_EXISTENTIALS is set.
Use unknownRetain instead of native retain in dynamicCastToExistential.
