- detect and forbid non-positive size casts
- detect and forbid negative struct pattern literal indices
- avoid invalid constant folding of negative based literals
- new net decl to replace net pseudo-type
- support nets with complex base types, including typenames
- support var declaration type prefix for all data types
- support var as lone type shorthand
- refactor AST representation of strengths
- traversal helpers for treating nets as variables
- use decl traversals where appropriate
- delegate cast type and sign resolution to TypeOf conversion
- internal support for injecting data declarations into statements
- fix size and sign of unbased unsized literals used in casts
- avoid generating many unnecessary explicit casts
- support casts which depend on localparams within procedures
- expression traversal correctly visits types within type casts
- fix typeof on expressions of net types
- handle additional edge cases for unsized integer array patterns
- preserve signedness of implicitly flattened unpacked integer arrays
- number literals are parsed rather than stored as strings
- fix array query functions used on non-trivial number literals
- more efficient expression simplification recursion
- expanded constant folding scenarios
- significant refactor of struct conversion
- significant refactor of typedef conversion
- scoping support in multipack conversion
- scoping support in typeof conversion
- interface conversion only waits for type resolution of modports
- typeof conversion resolves struct field accesses
- logic conversion only converts logic data declarations
- struct conversion only converts within modules
- fix nested type traversal order causing premature struct conversion
- explicit enum casts in source are converted to size casts
- conversion for basic pattern array literals of unsized numbers
- unsized number array literals preserve signing
- more aggressive ternary simplification
- the ternary expressions were previously used to decide the direction
of generated part selects
- this fixes an issue where ternaries were generated for LHSs
- struct conversion handles directionality of fields
- struct conversion supports minus part selects
- fixed incorrect handling of directional part selects in multi-packed
conversion
- multi-packed conversion defines standard ranges in terms of
directional part selects for clarity
- fixed potential loop due to overeager untagging in multi-packed
conversion
- param type conversion properly supports deferred param type resolution
- fixed struct conversion incomplete Subroutine traversal
- struct conversion excludes param types from conversion
- parameters are defaulted to have integer type
- Trace comments cover module items, decls, and stmts
- Added pseudo-lexer to Alex parser for monadic Position production
- Added Position to every DeclToken
- Removed Comment PackageItem
- Added CommentStmt and CommentDecl
- Fixed traversal skipping outer MIAttr ModuleItems
- Generally cleaned up Parser modules
