These changes caused a number of issues:
1. No debug info is emitted when a release-debug info compiler is built.
2. OS X deployment target specification is broken.
3. Swift options were broken without any attempt any recreating that
functionality. The specific option in question is --force-optimized-typechecker.
Such refactorings should be done in a fashion that does not break existing
users and use cases.

This patch splits add_swift_library into two functions one which handles
the simple case of adding a library that is part of the compiler being
built and the second handling the more complicated case of "target"
libraries, which may need to build for one or more targets.
The new add_swift_library is built using llvm_add_library, which re-uses
LLVM's CMake modules. In adapting to use LLVM's modules some of
add_swift_library's named parameters have been removed and
LINK_LIBRARIES has changed to LINK_LIBS, and LLVM_LINK_COMPONENTS
changed to LINK_COMPONENTS.
This patch also cleans up libswiftBasic's handling of UUID library and
headers, and how it interfaces with gyb sources.
add_swift_library also no longer has the FILE_DEPENDS parameter, which
doesn't matter because llvm_add_library's DEPENDS parameter has the same
behavior.
Until now, only indirect fields that didn't belong to a C union (somewhere
between the field declaration and the type in which it is indirectly
exposed) were imported in swift. This patch tries to provide an approach
that allows all those fields to be exposed in swift. However, the downside
is that we introduce new intermediate fields and types, some of the fields
may already have been manually defined in type extension (as seen with the
GLKit overlay).
The main idea here is that we can simply expose the anonymous
struct/unions from which the indirect types are taken and then use swift
computed properties to access the content of those anonymous
struct/unions. As a consequence, each time we encounter an anonymous
struct or union, we actually expose it at __Anonymous_field<id> (where id
is the index of the field in the structure). At this point, we use the
existing mechanism to expose the type as
__Unnamed_<struct|union>_<fieldname>. Then, each indirect field is exposed
as a computed property.
The C object:
typedef union foo_t {
struct {
int a;
int b;
};
int c;
} foo_t;
Is imported as
struct foo_t {
struct __Unnamed_struct___Anonymous_field1 {
var a : Int32
var b : Int32
}
var __Anonymous_field1 : foo_t.__Unnamed_struct___Anonymous_field1
var a : Int32 {
get {
return __Anonymous_field1.a
}
set(newValue) {
__Anonymous_field1.a = newValue
}
}
var b : Int32 {
get {
return __Anonymous_field1.b
}
set(newValue) {
__Anonymous_field1.b = newValue
}
}
var c : Int32
}
This has the advantage to work for both struct and union, even in case we
have several nested anonymous struct/unions. This does not require to know
the size and/or the offset of the fields in the structures and thus can be
properly implemented using front-end data.

...to remove the temptation to put everything in one file with the same
name as the module. This doesn't do anything for overlays that /already/
have everything in one file with the same name as the module, except for
a few easy cases; we can unpack the rest later.
os/activity.h or os/log.h. Update cmake files again, hardcoding a Darwin
dependency. The script does not notice that Foundation depends on
CoreGraphics, so add that manually.
Also found that MapKit is supported on WATCHOS but we didn't have dependencies
for that.
Favor one line per supported SDK instead of catch-all dependency lines.
Distinguish from SDKs which have no dependencies vs SDKs which are
unsupported on a particular platform by printing `unsupported` to the
console and remove the line in the cmake file because it should
not exist anyway.
This full cleanup was not done before because of circularity detected by the
util, which has since been fixed.
Support directories with spaces.
added the build breaks. There's already a tool to get proper
dependencies, `utils/find-overlay-dependencies.sh`, so this patch
allows that tool to update the `CMakeLists.txt` files in-place.
Also it adds a line to the `CMakeLists.txt` files for each SDK so that the tool works.
As of now:
* old APIs are just marked as `deprecated` not `unavaiable`. To make it
easier to co-operate with other toolchain repos.
* Value variant of API is implemented as public @private
`_ofInstance(_:)`.
This is another necessary step in introducing changes
for SE-0107: UnsafeRawPointer.
UnsafeRawPointer is great for bytewise pointer operations.
OpaquePointer goes away.
The _RawByte type goes away.
StringBuffer always binds memory to the correct CodeUnit
when allocating memory.
Before accessing the string, a dynamic element width check
allows us to assume the bound memory type.
Generic entry points like atomicCompareExchange no longer handle
both kinds of pointers. Normally that's good because you
should not be using generics in that case, just upcast
to raw pointer. However, with pointers-to-pointers
you can't do that.
As a first step to allowing the build script to build *only*
static library versions of the stdlib, change `add_swift_library`
such that callers must pass in `SHARED`, `STATIC`, or `OBJECT_LIBRARY`.
Ideally, only these flags would be used to determine whether to
build shared, static, or object libraries, but that is not currently
the case -- `add_swift_library` also checks whether the library
`IS_STDLIB` before performing certain additional actions. This will be
cleaned up in a future commit.
At some point I want to propose a revised model for exports, but for now
just mark that support for '@exported' is still experimental and subject
to change. (Thanks, Max.)
The rule changes are as follows:
* All functions (introduced with the 'func' keyword) have argument
labels for arguments beyond the first, by default. Methods are no
longer special in this regard.
* The presence of a default argument no longer implies an argument
label.
The actual changes to the parser and printer are fairly simple; the
rest of the noise is updating the standard library, overlays, tests,
etc.
With the standard library, this change is intended to be API neutral:
I've added/removed #'s and _'s as appropriate to keep the user
interface the same. If we want to separately consider using argument
labels for more free functions now that the defaults in the language
have shifted, we can tackle that separately.

The standard library has grown significantly, and we need a new
directory structure that clearly reflects the role of the APIs, and
allows future growth.
See stdlib/{public,internal,private}/README.txt for more information.
