This changes layout of the parameter metadata from single tuple record
(in case of materializable type) to N records each corresponding to
invididual function parameter, where functions with no parameters
`() -> Void` get 0 records allocated.
Except GenericEnvironment.h, because you can't meaningfully use a
GenericEnvironment without its signature. Lots less depends on
GenericSignature.h now. NFC
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.
Add a 'hasExplicitAnyObject()' bit to ProtocolCompositionType
to represent canonical composition types containing '& AnyObject'.
Serialize this bit and take it into account when building
ExistentialLayouts.
Rename ProtocolCompositionType::getProtocols() to getMembers()
since it can contain classes now, and update a few usages that
need further attention with FIXMEs or asserts.
For now, nothing actually constructs these types, and they will
trigger arounds asserts. Upcoming patches will introduce support
for this.
This makes the demangler about 10 times faster.
It also changes the lifetimes of nodes. Previously nodes were reference-counted.
Now the returned demangle node-tree is owned by the Demangler class and it’s lifetime ends with the lifetime of the Demangler.
Therefore the old (and already deprecated) global functions demangleSymbolAsNode and demangleTypeAsNode are no longer available.
Another change is that the demangling for reflection now only supports the new mangling (which should be no problem because
we are generating only new mangled names for reflection).
Changes:
* Terminate all namespaces with the correct closing comment.
* Make sure argument names in comments match the corresponding parameter name.
* Remove redundant get() calls on smart pointers.
* Prefer using "override" or "final" instead of "virtual". Remove "virtual" where appropriate.
When DynamicSelfType occurs outside of a class body (for example,
inside of a SIL function), it is not enough to simply utter 'Self',
because then we lose the underlying type.
Instead, print it out as '@dynamic_self Foo', where 'Foo' is the
underlying class type or archetype, and add parser support for
the same.
Fixes <rdar://problem/27735857>.
The metadata system doesn't actually unique based on labels
correctly, so the test case has to play some games. That's
something that will be easier to fix when there are fewer
clients poking at the internals of the metadata runtime.
just the address. Use this to avoid repeatedly reading metadata so
often (even if it's cached, this is better). Fix some bugs involving
nominal type parents.
