69/// @brief Visitor object which will generate llvm IR for a syntax tree. This
70/// provides the majority of the code generation functionality except for
71/// attribute access. This design allows for custom geometry to define their
72/// IR implementations for these accesses by deriving and extending this
73/// generator with ast::Attribute handling (see PointComputeGenerator.h and
74/// VolumeComputeGenerator.h for examples).
75/// @note The visit/traverse methods work slightly differently to the normal
76/// Visitor to allow proper handling of errors and visitation history. Nodes
77/// that inherit from ast::Expression can return false from visit() (and so
78/// traverse()), but this will not necessarily stop traversal altogether.
79/// Instead, any ast::Statements that are not also ast::Expressions i.e.
80/// Block, ConditionalStatement, Loop, DeclareLocal, etc override their visit
81/// and traverse methods to handle custom traversal order, and the catching
82/// of failed child Expression visit/traverse calls. This allows errors in
83/// independent Statements to not halt traversal for future Statements and so
84/// allow capturing of multiple errors in an ast::Tree in a single call to
85/// ComputeGenerator::generate().
