* 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
Also: OG compiler debug info for foreach iterator changed to match actual variable name
Adds:
- ast/DebugStatementMarker: for "intrusive debug" (ecompile -i) instructions
- codegen/DebugBlockGuard: pushes and pops debug block #
- format/DebugStoreSerializer: writes .dbg and .dbg.txt files
- representation/DebugBlock: holds parent block # and local variable names for each block
- representation/DebugStore: holds all debug information
Adds:
- analyzer/Constants: holds constant name -> value for lookup
- ast/ConstDeclaration: AST node for a const declaration
- optimizer/ConstValidator: validates that an optimized expression is valid to use as a constant.
the Optimizer converts Identifiers that refer to a constant to the optimized constant value.
Add:
- ast/ExitStatement: AST node for the exit statement.
- ast/ReturnStatement: AST node for the return statement.
- only handles top-level returns and returns inside program declarations, which do the same thing: progend.
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.
