* added escriptgrammar as external lib where it belongs. Silenced warnings.
* bscript compiler warning fixes
* special include file to get rid of gcc warnings about antlr4
* misc windows warnings
* time specifc warnings
* buildfix + apple warnings
* never trust apple
* windows debug build warnings
* some windows clang warnings
* last warning fix
* Move more specialized expression types from optimizer to AST builder
VarStatement now handles its own value consumption
* Move assign-multisubscript-consume logic to the instruction generator
Renamed:
- GetMember to MemberAccess
- SetMember to MemberAssignment
- SetMemberByOperator to MemberAssignmentByOperator
- AssignVariableConsume to VariableAssignmentStatement
Adds:
- ast/ElementAccess: AST node for x[a] or x[a,b,...] (may be get or set)
- ast/ElementAssignment: AST node for x[a] := b;
- ast/ElementIndexes: AST node to hold all indexes for element lookup
- optimizer/AssignmentOptimizer: optimizes := in different circumstances
Adds:
- ast/DictionaryEntry: AST node for a key -> value pair in a dictionary initializdr
- ast/DictionaryInitializer: AST node for creating a new dictionary
- ast/UninitializedValue: AST node for an uninit object
Adds:
- UnaryOperator: AST node for unary operators -, ++, --, and so forth
- UnaryOperatorOptimizer: optimizes a unary operator with its operand
- now integer and float negation, and integer inversion
- later x[y]++ to a single instruction
Also:
- automatically include basic.em, which includes some parameter defaults like -1.
This allows the compiler to generate output for a hello, world script with the exact same .ecl output as the legacy compiler.
Adds support for var statements at the global level.
Adds:
- analyzer/Variables: keeps track of the variables in scope (either local or global).
- ast/Identifier: AST node for an identifier.
- The optimizer will replace constant identifiers with their constant value (in a later commit).
- The semantic analyzer will set the variable field for local or global variable identifiers.
- ast/VarStatement: AST node for a var statement.
- A single var statement will generate one VarStatement per variable declared.
- model/Variable: Describes a variable, including its index within its scope.
Adds:
- ast/Argument: AST node for an argument passed to a function.
- ast/FunctionCall: AST node for a function call.
- codegen/ModuleDeclarationRegistrar: The code generator registers module function declarations with this in order to determine module indexes and function indexes for instructions.
- model/FunctionLink: this is a reference either:
- from: a FunctionCall or a FunctionReference
- to: a ModuleFunctionDeclaration or a UserFunction
- optimizer/ReferencedFunctionGatherer: a visitor that determines which module functions and user functions are referenced, by looking at function calls and function references.
Also:
- CodeGenerator registers module functions
- InstructionGenerator generates code for function calls
- InstructionEmitter generates TOK_FUNC instructions
- StoredTokenDecoder decodes TOK_FUNC instructions
After all of this, the compiler can compile print("hello, world");
