2021-02-05Initial implementation of interface conjunctions (#1691)Tim Foley
The basic feature here is the ability to use the `&` operator to produce the conjunction/intersection of two interfaces. That is, you can have interfaces: interface IFirst { int getFirst(); } interface ISecond { int getSecoond(); } and if you need a generic function where the type parameter `T` must conform to *both* of these interfaces, you express that by constraining the parameter to the intersection of the interfaces: void someFunction<T : IFirst & ISecond>(T value) { ... } Without this feature, the main alternative an application would have is to define an intermediate interface, like: interface IBoth : IFirst, ISecond {} Forcing users to deal with an intermediate interface creates more work for type authors (they need to remember to inherit from the right combined interface(s)), or for `extension` authors (when you add `ISecond` to a type that used to just support `IFirst`, you had better also add `IBoth`). In the worst case, a family of N related "leaf" interfaces would give rise to an exponential number of intermediate interfaces to represnt the possible combinations. A conjunction like `IFirst & ISecond` is officially its own type, and can be used to declare a type alias: typealias IBoth = IFirst & ISecond; This change only includes the first pass of work on this feature, so there are several caveats to be aware of: * Using a conjunction as part of an inheritance clause is not yet supported (e.g., `struct X : IFirst & ISecond`). This is true even if the conjunction was introduced by an intermediate `typealias` * The `&` syntax introduced here is only parsed in places where only a type (not an expression) is possible. This means you cannot do things like cast to a conjunction with `(IFirst & ISecond)(someValue)`. * This work *should* apply to conjunctions of more than two interfaces (like `IA & IB & IC`) but that has not yet been tested * In the long run it may be sensible to allow conjunctions that use concrete types, but we really ought to have the semantic checking logic rule that out for now. * During testing, I encountered compiler crashes when trying to use this feature together with `property` declarations. Further investigation and debugging is called for. * The handling of conjunction types is currently incomplete, in that there are many equivalences the compiler does not yet understand. For example, it is clear that `IA & IB` is equivalent to `IB & IA`, but the compiler currently does not understand this and will treat them as different types. A deeper implementation approach is called for. * Conjunctions are currently only supported for generic type parameter constraints, when performing full specialization. Use of conjunctions for existential-type value parameters or with dynamic dispatch is not yet supported.

Remove unused function from IRSerialReader. * Small fixes around naming. Remove long comment from slang-serialize.h - as covered in serialization.md * Remove long comment in slang-serialize.h as covered in serialization.md * More information about doing replacements on read for AST and problems surrounding. * Typo fix. * Spelling fixes. * Value serialize. * Value types with inheritence. * Use value reflection serial conversion for more AST types * Use automatic serialization on more of AST. * Get the types via decltype, simplifies what the extractor has to do. * Update the serialization.md for the value serialization. * Small doc improvements. * Update project. * Remove ImportExternalDecl type Added addImportSymbol and ImportSymbol type Fixed bug in container which meant it wouldn't read back AST module * Because of change of how imports and handled, store objects as SerialPointers. * First pass symbol lookup from mangled names. * Cache current module looked up from mangled name. * Fix SourceLoc bug. Improve comments. * Added diagnostic on mangled symbol not being found * Fix typo. * WIP serializing stdlib. * WIP serializing stdlib in. * Fix problem serializing arrays that hold data that is already serialized. * Remove clash of names in MagicTypeModifier. * Make conversion from char to String explicit. Fix reference count issue with SerialReader. * Add code to save/load stdlib. * Use return code to avoid warning - SerialContainerUtil::write(module, options, &stream)) * Make all String numeric ctors explicit. Added isChar to UnownedStringSlice. Added operator== for UnownedStringSlice to String to avoid need to convert to String and allocate. * Add error check to readAllText. * tabs -> spaces on String.h * tab -> spaces String.cpp * Remove msg for StringBuilder, just build inplace for exceptions. * Check SerialClasses - for name clashes. Renamed Modifier::name as Modifier::keywordName * Handling of extensions when deserializing AST - updating the moduleDecl->mapTypeToCandidateExtensions Co-authored-by: Tim Foley <tim.foley.is@gmail.com>

2020-06-08Small fixes/improvements based on review. (#1379)jsmall-nvidia
2020-06-05ASTNodes use MemoryArena (#1376)jsmall-nvidia
* Add a ASTBuilder to a Module Only construct on valid ASTBuilder (was being called on nullptr on occassion) * Add nodes to ASTBuilder. * Compiles with RefPtr removed from AST node types. * Initialize all AST node pointer variables in headers to nullptr; * Initialize AST node variables as nullptr. Make ASTBuilder keep a ref on node types. Make SyntaxParseCallback returns a NodeBase * Don't release canonicalType on dtor (managed by ASTBuilder). * Give ASTBuilders a name and id, to help in debugging. For now destroy the session TypeCache, to stop it holding things released when the compile request destroys ASTBuilders. * Moved the TypeCheckingCache over to Linkage from Session. * NodeBase no longer derived from RefObject. * Only add/dtor nodes that need destruction. First pass compile on linux.
