This is needed for unit tests to import app modules, but could also be used
to get rid of the "/32" used for the standard libraries.
This is the rest of <rdar://problem/16776466>
Swift SVN r17177
...due to a code signing issue. See <rdar://problem/16328065> for details.
Also, fix an error where the wrong file name was being used for framework
docs.
No release note because no one is using Swift frameworks yet (besides LLDB).
Swift SVN r15074
The driver infers the filename from the module file by replacing the extension,
and passes the explicit path to the swiftdoc file to the frontend. But there
is no option in the driver to control emission of swiftdoc (it is always
emitted, and name is always inferred from the swiftmodule name).
The swiftdoc file consists of a single table that maps USRs to {brief comment,
raw comment}. In order to look up a comment for decl we generate the USR
first. We hope that the performance hit will not be that bad, because most
declarations come from Clang. The advantage of this design is that the
swiftdoc file is not locked to the swiftmodule file, and can be updated,
replaced, and even localized.
Swift SVN r14914
This won't ever happen naturally, but by either messing with the module file
or asking the compiler to load something that isn't a module at all we could
end up hitting the assert.
<rdar://problem/16274875>
Swift SVN r14902
Make the name lookup interfaces all take DeclNames instead of identifiers, and update the lookup caches of the various file units to index their members by both compound name and simple name. Serialized modules are keyed by identifiers, so as a transitional hack, do simple name lookup then filter the results by compound name.
Swift SVN r14768
Swift can now find modules inside framework bundles matching this layout:
Foo.framework/
Foo.swiftmodule/
ARCH.swiftmodule
Currently, ARCH is the architecture name used by build configurations (#if),
but this was more done out of convenience than anything else (there's
currently no access to the current target from the ASTContext). We'll need
to revisit this if/when we decide to support architecture subtypes (armv7s
vs. armv7 vs. arm), at which point we'll also have to deal with fallback
architectures.
Framework search paths are specified using -F. Like bare import paths, there
are currently no "built-in framework search paths".
The master plan for Swift frameworks is in <rdar://problem/16062602>.
<rdar://problem/16155907>
Swift SVN r14363
This is more in line with all other modules currently on our system.
If/when we get our final name for the language, we're at least now set
up to rename the library without /too/ much trouble. (This is mostly just
a lot of searching for "import swift", "swift.", "'swift'", and '"swift"'.
The compiler itself is pretty much just using STDLIB_NAME consistently now,
per r13758.)
<rdar://problem/15972383>
Swift SVN r14001
From now on, /any/ changes to SIL or AST serialization must increment
VERSION_MINOR in ModuleFormat.h.
The original intent of VERSION_MAJOR/VERSION_MINOR was that VERSION_MAJOR
would only increment when backwards-incompatible changes are introduced,
and VERSION_MINOR merely indicates whether to expect additional information.
However, the module infrastructure currently isn't forgiving enough to accept
even backwards-compatible changes to the record schemas, and the SIL
serialization design might not be compatible with that at all.
So for now, treat any version number 0.x as incompatible with any other 0.y.
We can bump to 1 when we hit stability.
<rdar://problem/15494343>
Swift SVN r13841
This is mostly useful for the standard library, whose name is going to
change to "Swift" soon. (See <rdar://problem/15972383>.) But it's good DRY.
Swift SVN r13758
Also, disallow creating Modules and FileUnits on the stack. They must always
live as long as the ASTContext.
<rdar://problem/15596964>
Swift SVN r13671
Also, don't allow file-relative imports (i.e. don't consider a /source file's/
location as an include path). Both of these should be requested by the user,
at least at this point.
Swift SVN r13249
This keeps us from having to deal with fat swiftmodules for now.
In the long run we're hoping to solve this problem with build configurations,
so that a single module file can support multiple architectures.
(See <rdar://problem/15056323>)
<rdar://problem/15204953>
Swift SVN r13135
This necessitated adding a new function to validate a serialized AST, so
that we can get the same information that used to be extracted from the
section header.
For now, we'll continue accepting the wrapped ASTs as well, since we
haven't changed the existing debug info generator.
Swift SVN r12922
Thanks to the way we've set up our diagnostics engine, there's not actually
a reason for /everything/ to get rebuilt when /one/ diagnostic changes.
I've split them up into five categories for now: Parse, Sema, SIL, IRGen,
and Frontend, plus a set of "Common" diagnostics that are used in multiple
areas of the compiler. We can massage this later.
No functionality change, but should speed up compile times!
Swift SVN r12438
Also updated findModule() in SourceLoader.cpp and SerializedModuleLoader.cpp to get the ImportSearchPaths from the ASTContext’s SearchPathOpts, instead of directly from the ASTContext.
Swift SVN r11214
Added a new SearchPathOptions class to swiftAST, which will contain options like import search paths and the SDK path.
Moved the RuntimeIncludePath from CompilerInvocation into SearchPathOptions. For now, at least, the RuntimeIncludePath is handled separately from other ImportSearchPaths, since we can’t yet guarantee that RuntimeIncludePath is set up before we parse the ImportSearchPaths.
Added a SearchPathOptions member to ASTContext.
Updated findModule() in SourceLoader.cpp and SerializedModuleLoader.cpp to check RuntimeIncludePath after everything else if no module was found. (This matches existing behavior, which had RuntimeIncludedPath at the end of ImportSearchPaths.)
Swift SVN r11213
Each loaded file gets added to the main module, rather than being a standalone
separate module. In theory, this will be used to assemble several partial
ASTs into a complete module. In practice, there's still a ways to go...but
this can already round-trip a single module file.
This also factors out the FileUnit-creating part of SerializedModuleLoader,
which should help clients like SourceKit that don't need to search for a
swiftmodule file associated with a particular import.
Swift SVN r10952
This completes the FileUnit refactoring. A module consists of multiple
FileUnits, which provide decls from various file-like sources. I say
"file-like" because the Builtin module is implemented with a single
BuiltinUnit, and imported Clang modules are just a single FileUnit source
within a module.
Most modules, therefore, contain a single file unit; only the main module
will contain multiple source files (and eventually partial AST files).
The term "translation unit" has been scrubbed from the project. To refer
to the context of declarations outside of any other declarations, use
"top-level" or "module scope". To refer to a .swift file or its DeclContext,
use "source file". To refer to a single unit of compilation, use "module",
since the model is that an entire module will be compiled with a single
driver call. (It will still be possible to compile a single source file
through the direct-to-frontend interface, but only in the context of the
whole module.)
Swift SVN r10837
Part of the FileUnit restructuring. A serialized module is now represented as
a TranslationUnit containing a single SerializedASTFile.
As part of this change, the FileUnit interface has been made virtual, rather
than switching on the Kind in every accessor. We think the operations
performed on files are sufficiently high-level that this shouldn't affect us.
A nice side effect of all this is that we now properly model the visibility
of modules imported into source files. Previously, we would always consider
the top-level imports of all files within a target, whether re-exported or
not.
We may still end up wanting to distinguish properties of a complete Swift
module file from a partial AST file, but we can do that within
SerializedModuleLoader.
Swift SVN r10832
The goal of this series of commits is to allow the main module to consist
of both source files and AST files, where the AST files represent files
that were already built and don't need to be rebuilt, or of Swift source
files and imported Clang headers that share a module (because they are in
the same target).
Currently modules are divided into different kinds, and that defines how
decls are looked up, how imports are managed, etc. In order to achieve the
goal above, that polymorphism should be pushed down to the individual units
within a module, so that instead of TranslationUnit, BuiltinModule,
SerializedModule, and ClangModule, we have SourceFile, BuiltinUnit,
SerializedFile, and ClangUnit. (Better names welcome.) At that point we can
hopefully collapse TranslationUnit into Module and make Module non-polymorphic.
This commit makes SourceFile the subclass of an abstract FileUnit, and
makes TranslationUnit hold an array of FileUnits instead of SourceFiles.
To demonstrate that this is actually working, the Builtin module has also
been converted to FileUnit: it is now a TranslationUnit containing a single
BuiltinUnit.
Swift SVN r10830
Each one has a different kind of lookup cache anyway, and there's no real
reason to have them share storage at the cost of type-safety.
Swift SVN r9242
docs/Resilience.rst describes the notion of a resilience component:
if the current source file is in the same component as a module being
used, it can use fragile access for everything in the other module,
with the assumption that everything in a component will always be
recompiled together.
However, nothing is actually using this today, and the interface we
have is probably not what we'll want in 2.0, when we actually implement
resilience.
Swift SVN r9174
getDisplayDecls() was introduced for ":print_module" and works slightly differently, e.g.
it will return the decls from a shadowed clang module, since we want to display them.
Swift SVN r7909
As a bring-up hack, the module serializer would write a special record,
FALL_BACK_TO_TRANSLATION_UNIT, if it encountered something it didn't know
how to serialize. This then directed the deserializer to ignore the
contents of the module file and instead reload the original source file.
Now that we can serialize pretty much everything*, though, we don't need
this, and instead we'd rather know where the serialization coverage has
gaps (by asserting).
Swift SVN r7752
Add tools/lldb-moduleimport-test, which simulates LLDB importing modules
from the __apple_ast section in Mach-O files and use it to regression-test
the new API.
