- all inputs are now decoded as UTF-8, regardless of the platform
- decoding failures are now tolerated via transliteration given errant
characters are generally expected to appear in comments
This adds support for typed valued parameters declared in parameter port
lists without explicitly providing a leading `parameter` or `localparam`
marker.
- use iverilog's -gstrict-expr-width throughout test suite
- add warnings for excess bits or padding zeroes in number literals
- add new --oversized-numbers parameter to retain support for unsized
numbers wider than 32 bits
- localized use of oversized numbers to new truncate test suite which
verifies the behavior of both modes, and compares against the known
behavior of iverilog
- detect and forbid non-positive size casts
- detect and forbid negative struct pattern literal indices
- avoid invalid constant folding of negative based literals
- 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
- 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
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.
- 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
