Added a new DiagnosticOptions class to swiftBasic, and added a DiagnosticOptions member to CompilerInvocation.
Added a static ParseDiagnosticArgs function to parse diagnostic-related arguments.
Added -verify to FrontendOptions.td, and added support for parsing -verify in ParseDiagnosticArgs.
Updated frontend_main() to enable and trigger the DiagnosticVerifier when -verify is passed.
Swift SVN r11318
Removed CompilerInvocation::TargetTriple and replaced it with CompilerInvocation::TargetOpts, a TargetOptions object.
Added a static ParseTargetArgs function to set up TargetOptions, and moved handling of -target into that function.
Swift SVN r11288
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
Added a new ClangImporterOptions class which wraps the ModuleCachePath and ExtraArgs for the Clang importer.
Added a new ParseClangImporterArgs static function which fills in the passed-in ClangImporterOptions.
Updated CompilerInvocation and CompilerInvocation::parseArgs() to use ClangImporterOptions and ParseClangImporterArgs, respectively.
Swift SVN r11180
Added a new FrontendOptions class, which will eventually contain the options for controlling the behavior of the frontend. (This is similar to Clang’s FrontendOptions class.)
Moved InputFilenames, OutputFilename, ModuleName, and SerializedDiagnosticsPath from CompilerInvocation into FrontendOptions.
Split out argument parsing for options in FrontendOptions into a separate ParseFrontendArgs static function.
Swift SVN r11155
'doIt' is semantically meaningless, and doesn't mention the fact that nothing
has actually been compiled yet (to SIL, to IR, or to machine code).
'performParse' matches the compiler flag -parse, which stops after
type-checking.
No functionality change.
Swift SVN r10951
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
New rules for the driver (first match):
1. -repl: no input files allowed
2. -parse-sil: one input file allowed
3. -parse-as-library: any number of input files, all treated as Library
4. one input, extension is .sil: treated as SIL
5. one input: treated as Main
6. many inputs: treated as Library by default; "main.swift" is treated as Main
If we want more control here we can also add a -main-file option to explicitly
call out the main source file, but this at least unblocks building an entire
app target (like ListMaker) with a single Swift invocation.
Swift SVN r9890
This is useful in -i and REPL modes, which do not have a separate linking
step. This version of the -l flag doesn't rely on TranslationUnit. I also
cleaned up the library-loading diagnostics.
Swift SVN r9488
Being able to pass -l to the driver isn't so interesting, and it's an
extra field that lives on TranslationUnit for no reason. Just remove it.
This doesn't interfere with autolinking, i.e. inferring -l flags based on
imported modules.
Swift SVN r9241
Once we have multiple SourceFiles in a TranslationUnit, it no longer makes
sense to say "only SILGen decls starting from element N" without specifying
which source file you mean.
Also, clarify ownership by having performSILGeneration return a unique_ptr
instead of just a bare pointer.
Swift SVN r9112
...unless the functions are declared [transparent], or if we're in an
immediate mode (in which case we won't get a separate chance to link
against the imported TUs).
This is an optimization that will matter more when we start dealing with
Xcode projects with many cross-file dependencies, especially if we have
some kind of implicit import of the other source files in the project.
In the future, we may want to parse more function bodies for the purpose
of inlining, not just the transparent ones, but we weren't taking
advantage of that now, so it's not a regression. (We're still not taking
advantage of it even for [transparent] functions.)
Swift SVN r7698
ClangImporter::create had a 'weak' attribute but it did not actually have the desired effect,
static libraries still want to link to ClangImporter::create if it is used.
Avoiding linking ClangImporter kinda "worked" because CompilerInvocation::setSDKPath was inline,
so if you didn't call it then you didn't need to link to Clang importer, but that is avoiding
ClangImporter statically, not dynamically.
You could see this by moving CompilerInvocation::setSDKPath out-of-line and then sil-opt would fail to link.
In order to have clients avoiding linking Clang, introduce NullClangImporter which just returns null for the
ClangImporter constructor function.
Swift SVN r7465
Also have CompilerInvocation store the RuntimeIncludePath and calculate it via the MainExecutablePath
instead of the other way around (store MainExecutablePath and calculate RuntimeIncludePath when requested)
Swift SVN r7170
around everywhere
Fixes:
rdar://14585108 Code completion does not work at the beginning of the file
rdar://14592634 Code completion returns zero results at EOF in a function
without a closing brace
Swift SVN r6820
-Introduce PersistentParserState to represent state persistent among multiple parsing passes.
The advantage is that PersistentParserState is independent of a particular Parser or Lexer object.
-Use PersistentParserState to keep information about delayed function body parsing and eliminate parser-specific
state from the AST (ParserTokenRange).
-Introduce DelayedParsingCallbacks to abstract out of the parser the logic about which functions should be delayed
or skipped.
Many thanks to Dmitri for his valuable feedback!
Swift SVN r6580
This mainly removes the extraneous DiagnosticEngine and SourceMgr from CompilerInvocation.
Instances of these can be found via the CompilerInstance object.
Swift SVN r6496
Add a little dance in the setup of the Clang importer. Now, clients that don't care
about the clang importer don't have to link it in, just don't call setSDKPath()
Swift SVN r6462
* Added a mode in swift-ide-test to test code completion. Unlike c-index-test,
the code completion token in tests is a real token -- we don't need to
count lines and columns anymore.
* Added support in lexer to produce a code completion token.
* Added a parser interface to code completion. It is passed down from the
libFrontend to the parser, but its functions are not called yet.
* Added a sketch of the interface of code completion consumer and code
completion results.
Note: all this is not doing anything useful yet.
