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