Use the same style, and reuse the bulk of astgen to generate DfgVertex
related code. In particular allow for easier definition of custom
DfgVertex sub-types that do not directly correspond to an AstNode
sub-type. Also introduces specific names for the fixed arity vertices.
No functional change intended.
Use astgen to generate a more thorough version of AstNode::checkTree,
which checks that operands are or consistent structure and type, as
described in the @astgen op directives. Also change checkTree to always
run when --debug-check is given.
Fix discovered fallout.
Introduce the @astgen directives parsed by astgen, currently used for
the generation child node (operand) accessors. Please see the updated
internal documentation for details.
- Move DType representations into V3AstNodeDType.h
- Move AstNodeMath and subclasses into V3AstNodeMath.h
- Move any other AstNode subtypes into V3AstNodeOther.h
- Fix up out-of-order definitions via inline methods and implementations
in V3Inlines.h and V3AstNodes.cpp
- Enforce declaration order of AstNode subtypes via astgen,
which will now fail when definitions are mis-ordered.
