The code here should not type check, because we're adding a requirement to
an outer archetype.

I'm working on some changes to ArchetypeBuilder that will make this kind
of thing easier to catch.

dc7d433a40 Remove an overzealous assert. 
When we are able to type check an expression this assert is fine,
although of little value. In the context of failed type checks, though,
it can be actively harmful.

The issue is that we can attempt to solve smaller parts of the
constraint system and assign contextual types (e.g. for the arguments of
a function) despite not being able to drill into members.

Some of the diagnostics we emit in these cases are not terribly useful,
and I've opened rdar://problem/27982012 with one example.

[swiftc (38 vs. 5154)] Add crasher in swift::ArchetypeBuilder::mapTypeOutOfContext(...)
 2016-08-04 10:21:57 +02:00

75bd88968b SILGen: Allow extensions to define designated initializers of generic types 
Previously, if a generic type had a stored property with
a generic type and an initializer expression, we would
emit the expression directly in the body of each designated
initializer.

This is a problem if the designated initializer is defined
within an extension (even in the same source file), because
extensions have a different set of generic parameters and
archetypes.

Also, we've had bugs in the past where emitting an
expression multiple times didn't work properly. While these
might currently all be fixed, this is a tricky case to test
and it would be best to avoid it.

Fix both problems by emitting the initializer expression
inside its own function at the SIL level, and call the
initializer function from each designated initializer.

I'm using the existing 'variable initializer' mangling for this;
it doesn't seem to be used for anything else right now.

Currently, the default memberwise initializer does not use
this, because the machinery for emitting it is somewhat
duplicated and separate from the initializer expressions in
user-defined constructors. I'll clean this up in an upcoming
patch.

Fixes <https://bugs.swift.org/browse/SR-488>.

5cce5c4d1d [Parser] Refactor parsing of calls and call-like expressions. 
Rather than parsing the call arguments (or similar, e.g., subscript)
as a parenthesized expression or tuple, then later reworking that
ParenExpr/TupleExpr if a trailing closure comes along, then digging
through that ParenExpr/TupleExpr to pull out the arguments and
trailing closure... just parse the expression list and trailing
closure together, then directly form the appropriate AST node with
arguments/labels/label locations/trailing closure.

Fixes rdar://problem/19804707, which is an issue where trailing
closures weren't working with unresolved member expressions (e.g.,
".foo {... }"), and is a stepping-stone to SE-0111.

7bfaeb57f1 [SE-0081] Warn on deprecated where clause inside angle brackets 
and provide a fix-it to move it to the new location as referenced
in SE-0081.

Fix up a few stray places in the standard library that is still using
the old syntax.

Update any ./test files that aren't expecting the new warning/fix-it
in -verify mode.

While investigating what I thought was a new crash due to this new
diagnostic, I discovered two sources of quite a few compiler crashers
related to unterminated generic parameter lists, where the right
angle bracket source location was getting unconditionally set to
the current token, even though it wasn't actually a '>'.

1ae8e37058 Remove -enable-protocol-typealiases staging flag 
It looks like migration fixits are done, and this doesn't
expose any new bugs that were not possible before, because
you could already define typealiases inside protocol
extensions.

To prevent some compiler_crasher regressions, add a simple
circularity-breaking hack. I'll need to do a sweep to clean
these up some day soon.

d06d4e5ad7 [AST][Sema] Fixes the IterativeTypeChecker and better manages circular protocol inheritance 
The IterativeTypeChecker now use loops instead of recursion to help keep the stack size low
We diagnose circular dependencies for protocols in a more efficient manner and also prevent the possibility of infinite loops
