The clang compiler does not like using struct to reference a class object.
This patch removes all the struct keywords for __vpiNamedEvent objects
since they are now a class and can be called without a struct/class
qualifier.
This patch also removes all the extra class qualifiers from the rest of
the source code.
Add a new IVL_PR_FINAL process type.
Add a flag to NetScope in_final_ which is set when elaborating the
statement of a final procedure.
Add checks during statement elaboration for invalid statements in a
final procedure, similar to checks for statements in functions.
Do a final check to make sure no final blocks have delays.
In the vvp runtime, use "$final" as the flag for the thread created by
the final procedure. During compilation, instead of adding such a
thread to the sched_list, add it to a new schedule_final_list that
mirrors the schedule_init_list, but is run at the end of simulation.
Functions that appear in continuous assignment expressions and that
have hidden dependencies or side effects need to be re-evaluated
whenever any input to the expression changes. This patch adds support
in the compiler and vvp runtime to enable this. This is currently
activated for any system function call that has no arguments. The
user may also force it to be used for any user function by passing
the option -gstrict-ca-eval to the compiler driver.
This patch also removes the -dautomatic option which was used for
gaining confidence in the code that supports automatic tasks and
functions. It is believed that the testsuite provides reasonable
fault coverage, and further tests can be added if bugs are found.
Put together the infrastructure for elaborating analog statements,
including create the NetAnalogTop objects that hold analog statements
and are in turn held by the design.
While doing this, clean up the various unique initial/always enumerations
to use the ivl_process_type_t type.
In preparation for using the synthesize method to replace the
elaborate_net method of PExpr, rework the interface to the
synthesize() method. This changes no fnctionality, but does set
up the infrastructure for the next step.
