These are no longer required for correct scheduling. They are still
accepted for backward compatibility, but have no effect on simulation
and are dropped in the front-end. Also removed the then redundant
AstAlwaysPublic class.
Fixes#6442
There were a couple corner case bugs in V3Inline, and one in Dfg when
dealing with inlining of modules/variables.
V3Inline:
- Invalid code generated when inlining an input that also had an
assignment to it (Throws an ASSIGNIN, but this is sometimes reasonable
to do, e.g. hiererchical reference to an unonnected input port)
- Inlining (aliasing) publicly writeable input port.
- Inlining forcable port connected to constant.
Dfg:
- Inining publicly writeable variables
The tests that cover these are the same and fixing one will trigger the
other bug, so fixing them all in one go. Also cleanup V3Inline to be less
out of order and rely less on unique APIs only used by V3Inine (will
remove those in follow up patch).
Small step towards #6280.
* Add more directives to configuration files
Allow to set the same directives in configuration files that can also
be set by comment attributes (such as /* verilator public */ etc).
* Add support for lint messsage waivers
Add configuration file switch '-match' for lint_off. It takes a string
with wildcards allowed and warnings will be matched against it (if
rule and file also match). If it matches, the warning is waived.
