- add unified frontend configuration record to make adding future
options easier
- use ExceptT throughout, rather than using runExceptT at internal
boundaries
- support ports with sizes which depend on constant functions
- restore package item injection utility to package conversion module
- additional unbased unsized conversion test coverage
- references to other instances are no longer flagged
- special handling for genvars to avoid flagging and modport scoping
- interface inlining visits expressions in declarations
- Scoper has interface for removing entries
The interface conversion no longer substitutes parameters immediately,
instead fully scoping modports and allowing hierarchical constants to be
resolved separately. This fixes an issue where struct parameters could
lose their type information during substitution. The conversion also now
handles renaming references to the module or interface top-level scope.
- scoper item injection can no longer affect generate scoping
- cast conversion injects functions into the top level when possible
- cast conversion considers loop variables to be local
- `else if` generate blocks are still scopes at the current level
- moved 4 phases to initial set and 3 to final set
- fix synthetic unnamed genblocks preventing name resolution
- asgnop conversion folds in unisub when possible
- convert loops with no or many incrementations
- restrict AST node to only contain traditional initializations
- parser elaborates for loop decls into a synthetic block
- decl list codegen is now specific to parameter decl lists
- update jump conversion special cases for new representation
- first experiments with bimapM
- don't evaluate AST after procedural assignment collection
- don't use State monad during rewrite
- use Writer rather than State for procedural assignment collection
- use Scoper access generation shortcut utility
- cleanup as-patterns and legacy logic
- don't evaluate AST after depth collection
- don't use State monad during rewrite
- add Scoper utility for generating accesses without inserting element
- cleanup as-patterns and unnecessary verbosity
Disabling the package item injection routine used in the enum conversion
when there were no items to inject exposed cases where conversions would
generate duplicate declarations. The hierarchical constant and param
type conversions were trivially affected. The package conversion could
inject class items within a generate region and then re-inject them
outside of that generate region. The package conversions now uses an
upgraded generate region flattening utility to ensure injected class
items are seen. This also includes coverage for a conflict which
occurred even without the enum conversion change.
- remove needless comments generated during interface conversion
- filter null statements even in verbose mode
- hoist trace comment statements if doing so would prevent the need to
wrap a task or function body in a block
- add traces for global declarations
- add traces for parameter declaration lists
- add traces for module items within generate blocks
- avoid generating duplicate traces before declarations
- fix int type conversion not visiting function return type expressions
- add node-based traversal for decls visiting top level types and exprs
- explicit expr and type recursion in package ident resolution
- expose mapBothM traversal helper
- avoid double-visiting of decl types in certain conversions
- general refactoring in decl parsing
- restrict charge strength to trireg
- require const vars to be initialized
- forbid const net declarations
- disallow run-on declarations in packages and classes
