Desugaring of method calls into indirect calls through virtual tables +//! +//! This module is responsible for desugaring / transforming method calls into method calls through the +//! virtual table (for information regarding virtual tables refer to [`crate::lowering::vtable`]). In a +//! nutshell it will transform a method call such as `ptr^.foo()` into `__vtable_Fb#(ptr^.__vtable^).foo^(ptr^)`. +//! +//! However, not all method calls must be desugared but rather the following cases: +//! +//! # 1. Method calls within methods (and function block bodies) +//! The reason we want to desugar all method calls within (other) methods is for the fact that a non +//! overridden method may make use of an overridden method. For example consider +//! ```text +//! FUNCTION_BLOCK A +//! METHOD getName: STRING +//! getName := 'A'; +//! END_METHOD +//! +//! METHOD printName +//! printf('name = %s$N', ADR(getName())); +//! END_METHOD +//! END_FUNCTION_BLOCK +//! +//! FUNCTION_BLOCK B EXTENDS A +//! METHOD getName: STRING +//! getName := 'B'; +//! END_METHOD +//! +//! METHOD persistName +//! // Persist name to some file +//! END_METHOD +//! END_FUNCTION_BLOCK +//! +//! FUNCTION main +//! VAR +//! instanceA: A; +//! instanceB: B; +//! +//! refInstanceA: POINTER TO A; +//! END_VAR +//! +//! refInstanceA := ADR(instanceA); +//! refInstanceA^.printName(); // Calls `A::printName` which calls `A::getName` yielding "name = A" +//! +//! refInstanceA := ADR(instanceB); +//! refInstanceA^.printName(); // Calls `A::printName` which calls `B::getName` yielding "name = B" +//! END_FUNCTION +//! ``` +//! +//! As described in the main function, the calls to `printName` must happen at runtime. Were that not the case +//! then `printName` in A would resolve to `A::getName` at compile time, yielding an incorrect result for the +//! second `refInstanceA^.printName()` call. Desugaring the call to `printName` would result in +//! `printf('name = %s$N', ADR(__vtable_A#(THIS^.__vtable^).getName^(THIS^))`. +//! +//! # 2. Method calls through a pointer variable pointing to a class or function block +//! Essentially what is illustrated in 1. within the main function, consider: +//! +//! ```text +//! FUNCTION main +//! VAR +//! name: STRING; +//! instanceA: A; +//! instanceB: B; +//! +//! refInstanceA: POINTER TO A; +//! END_VAR +//! +//! refInstanceA := ADR(instanceA); +//! name := refInstanceA^.getName(); // Calls `A::getName` yielding "name = A" +//! +//! refInstanceA := ADR(instanceB); +//! name := refInstanceA^.getName(); // Calls `B::getName` yielding "name = B" +//! END_FUNCTION +//! ``` +//! +//! While this is a simple example, and in theory compilers would be able to derive the correct method calls +//! at compile time with some statical analysis, our compiler today is not able to do that. Specifically it +//! does not know that the second `refInstanceA` variable is pointing at `B` and the pointer call could be +//! simplified into a direct call to `B::getName()`. Instead, it relies on dynamic dispatch for a correct code +//! execution. Again, this is done by accessing the virtual table and calling the function pointer behind it. +//! In terms of ST code we would transform the calls into `__vtable_A#(refInstanceA^.__vtable^).getName^(refInstanceA^)`. +//! +//! +//! One final thing to note, while the casting of the virtual tables into concrete types is not really +//! interesting per-se, the upcasting from a child to its parent virtual table should at least be mentioned. +//! That is, as long as the virtual table definitions are compatible, upcasting can be performed without any +//! issues. Compatible here refers to the fact that the order of the member fields must be constant. More +//! specifically, the methods must be defined in "ancestral hierarchical order". To illustrate with the +//! previous examples, assume we have +//! ```text +//! TYPE __vtable_A: +//! STRUCT +//! getName: __FPOINTER TO A.getName := ADR(A.getName); +//! printName: __FPOINTER TO A.printName := ADR(A.printName); +//! END_STRUCT +//! END_TYPE +//! +//! TYPE __vtable_B: +//! STRUCT +//! getName: __FPOINTER TO B.getName := ADR(B.getName); // Overridden +//! printName: __FPOINTER TO A.printName := ADR(A.printName); // Inherited +//! persistName: __FPOINTER TO B.persistName := ADR(B.persistName); // New +//! END_STRUCT +//! ``` +//! +//! We can safely cast from B to A's virtual table because the layout is compatible and it would result in +//! `persistName` to be cut off in the cast. Were that not the case, e.g. if `getName` were to be swapped with +//! `persistName` then the call to `getName` would silently result in calling `persistName`. + +use plc_ast::{ + ast::{ + AstFactory, AstNode, AstStatement, CallStatement, CompilationUnit, PouType, ReferenceAccess, + ReferenceExpr, + }, + mut_visitor::{AstVisitorMut, WalkerMut}, + provider::IdProvider, +}; +use plc_source::source_location::SourceLocation; + +use crate::{ + index::Index, + resolver::{AnnotationMap, AnnotationMapImpl, StatementAnnotation}, + typesystem::{DataType, DataTypeInformation}, +}; + +pub struct PolymorphicCallDesugarer { + pub ids: IdProvider, + pub index: Option, + pub annotations: Option, + + pub in_method_or_function_block: Option, +} + +impl AstVisitorMut for PolymorphicCallDesugarer { + fn visit_implementation(&mut self, implementation: &mut plc_ast::ast::Implementation) { + if implementation.location.is_internal() { + return; + } + + self.in_method_or_function_block = match &implementation.pou_type { + PouType::FunctionBlock => Some(implementation.name.clone()), + PouType::Method { parent, .. } => Some(parent.clone()), + _ => None, + }; + + for statement in &mut implementation.statements { + statement.walk(self); + } + + self.in_method_or_function_block = None; + } + + fn visit_call_statement(&mut self, node: &mut plc_ast::ast::AstNode) { + // When dealing with a function call such as `ref^.foo()` we have to perform several steps to desugar + // it into a form that can be executed by the codegen without any intervention from our side, namely: + // 1.

Virtual table generation of classes and function blocks. +//! +//! This module is responsible for creating virtual tables for classes and function blocks, enabling +//! dynamic dispatch for polymorphic use cases. In short, every method call needs to be invoked indirectly +//! through a virtual table at runtime, which essentially is a collection of function pointers pointing to +//! the method implementations of POUs. The process of creating these virtual tables can be broken down into +//! three tasks: +//! +//! # 1. Virtual Table POU Member Field +//! Every root, i.e. non-extended, class or function block will receive a `__vtable: POINTER TO __VOID` member +//! field. For example a function block such as +//! ```text +//! FUNCTION_BLOCK A +//! VAR +//! one: DINT; +//! END_VAR +//! END_FUNCTION_BLOCK +//! ``` +//! will internally expand to +//! ```text +//! FUNCTION_BLOCK A +//! VAR +//! __vtable: POINTER TO __VOID; +//! one: DINT; +//! END_VAR +//! END_FUNCTION_BLOCK +//! ``` +//! Note that we use a `VOID` type here because the actual type assigned to the `__vtable` member differs from +//! POU to POU. +//! +//! # 2. Virtual Table Struct Definition +//! As mentioned, virtual tables are essentially just a collection of function pointers reflecting a POU. +//! Consider a function block A with methods `foo` and `bar` as well as a function block B extending A with +//! methods `foo` (inherited) and `bar` (overridden) as well as `baz` (new). For these two function blocks we +//! would generate the following virtual table structures: +//! +//! ```text +//! TYPE __vtable_A: +//! STRUCT +//! foo: __FPOINTER TO A.foo := ADR(A.foo); +//! bar: __FPOINTER TO A.bar := ADR(A.bar); +//! END_STRUCT +//! END_TYPE +//! +//! TYPE __vtable_B: +//! STRUCT +//! foo: __FPOINTER TO A.foo := ADR(A.foo); // inherited +//! bar: __FPOINTER TO B.bar := ADR(B.bar); // overridden +//! baz: __FPOINTER TO B.baz := ADR(B.baz); // new +//! END_STRUCT +//! END_TYPE +//! ``` +//! +//! # 3. Global Virtual Table Instances +//! The newly created `__vtable` member fields need to point to some instance of the corresponding virtual +//! table. For that we will create one global variable for each virtual table. Deriving from the previous +//! example we would generate the following two variables +//! ```text +//! VAR_GLOBAL +//! __vtable_instance_A: __vtable_A; +//! __vtable_instance_B: __vtable_B; +//! END_VAR +//! ``` +//! These global variables will later be assigned in the [`crate::lowering::initializers`] module. +//! +//! Note that the actual desugaring of method calls to make use of these virtual tables will happen in the +//! [`crate::lowering::polymorphism`] module. + +use plc_ast::{ + ast::{ + AccessModifier, AstFactory, AstNode, CompilationUnit, DataType, DataTypeDeclaration, LinkageType, + Pou, PouType, UserTypeDeclaration, Variable, VariableBlock, VariableBlockType, + }, + provider::IdProvider, +};
