The SDK directory is now confusing as the Windows target also has a SDK
overlay. In order to make this more uniform, move the SDK directory to
Darwin which covers the fact that this covers the XNU family of OSes.
The Windows directory contains the SDK overlay for the Windows target.
_modify mustn’t leave Collection storage in an inconsistent state when the code to which we’re yielding happens to throw. In practice this means that any cleanup code must happen in defer blocks before the yield.
Fix Dictionary to do just that and add tests to cover this functionality (as well as some other aspects of _modify).
In a previous commit, I banned in the verifier any SILValue from producing
ValueOwnershipKind::Any in preparation for this.
This change arises out of discussions in between John, Andy, and I around
ValueOwnershipKind::Trivial. The specific realization was that this ownership
kind was an unnecessary conflation of the a type system idea (triviality) with
an ownership idea (@any, an ownership kind that is compatible with any other
ownership kind at value merge points and can only create). This caused the
ownership model to have to contort to handle the non-payloaded or trivial cases
of non-trivial enums. This is unnecessary if we just eliminate the any case and
in the verifier separately verify that trivial => @any (notice that we do not
verify that @any => trivial).
NOTE: This is technically an NFC intended change since I am just replacing
Trivial with Any. That is why if you look at the tests you will see that I
actually did not need to update anything except removing some @trivial ownership
since @any ownership is represented without writing @any in the parsed sil.

Include some tuning and tweaking to reduce the constant factors
involved in string comparison. This yields considerable improvement on
our micro-benchmarks, and allows us to make less inlinable code and
have a smaller ABI surface area.
Adds more extensive testing of corner cases in our existing
fast-paths.
When in a post-binary-prefix-scan fast-path, we need to make sure we
are comparing a full-segment scalar, otherwise we miss situations
where a combining end-of-segment scalar would be reordered with a
prior combining scalar in the same segment under normalization in one
string but not the other.
This was hidden by the fact that many combining scalars are not
NFC_QC=maybe, but those which are not present in any precomposed form
have NFC_QC=yes. Added tests.
* Move most of the simd operators into an optional module
Adding simd to the stdlib caused some typechecker regressions. We can resolve them in the near-term by making the types universally available, but moving the arithmetic operators into a separate module that must be explicitly imported.
* Move two fuzzing tests back to fixed.
* Add SIMDOperators as a dependency for MediaPlayer.
* Move the .-prefixed operator declarations back into the stdlib.
@_fixed_layout classes have resilient vtables now, so we can add and
re-order methods.
Removing overrides is not legal though because they are subject to
devirtualization.
- We don't want to support changing a root class of a class, so don't
pretend that works. Some of these tests got removed recently in
d8104e7e43 but one still remained.
- For the tests that insert a non-root superclass in the inheritance
hierarchy, also test calling a method of the derived class. This
works now that we no longer hardcode vtable offsets and instead use
dispatch thunks.
Implements SE-0229.
Also updates simd module types in the Apple SDKs to use the new types, and updates a couple tests to work with the new types and protocols.
Adds a stat to SILInstruction's transferNodesFromList to record the
number of times an instruction is transfered to another block. This is
the only way I can think of to detect quadratic behavior of passes
that split basic blocks.
The remangler for the Objective-C runtime was dropping generic arguments
of extension contents, leading to collisions with @objc class names.
Include the generic arguments of extensions.
Fixes rdar://problem/45956357.
This is in preparation to make the code here more target agnostic for
porting to the Windows threading primitives. This is used pretty
extensively in the tests, so disabling tests would lose a chunk of
coverage.
