Unless explicitly declared a wire an enum output port is of variable type
and should be marked as IMPLICT_REG.
Currently this is only done when the base type of the enum is `logic`. But
it should be done for all enums regardless of their base type.
Without this change for example the following snippet
```
typedef enum {
A,
B
} E;
module M (
input E ei,
output E eo
);
always_comb eo = ei;
endmodule
```
fails with the following error message
test_enum.sv:11: error: eo is not a valid l-value in M.
test_enum.sv:8: : eo is declared here as wire.

Since commit 62fce50f8c ("Remove dead code for allocate_vec handling.")
vector.c only contains the license header and some include directives
but no actual code.
Remove the file.

Since commit 15cda5fe, forked threads are never embedded in the parent
thread, so we no longer need the special case code that ensured that
task/function calls were reaped before a join.
This also fixes GitHub issue #368.
Given a macro definition like this:
`define name `macro``text
the preprocessor should expand `macro, not `macrotext, when it expands
`name. This also ensures that
`define name(p,s) p``_``s
`define PREFIX my_prefix
`define SUFFIX my_suffix
`name(`PREFIX, `SUFFIX)
expands to
my_prefix_my_suffix
as the user would expect.
When -pfileline=1 is used the queue procedural warnings have file
and line information added to the messages. Also switch the trace
debugging to be off by default.
Also, Add some preliminary missing darray functionality.
When connecting module inout ports, an island is created. If there
is no other driver on one of the island ports, a tie-off is added.
In the case of a tri0 or tri1 net, this must have the correct (pull)
drive strength.
With a pattern rule, the recipe will only be executed once, even when
the rule has multiple targets. Using this to handle the output from
bison is included as an example in the GNU make manual.
This fixes the makefiles so that bison-generated header files will be
regenerated if they are deleted.
The current bison (3.7) generates a *.cc file that includes the header
it generated. For parse.cc this would be parse.hh. Right now, we rename
this header to have a common name used in other files, but this results
in a compile error for the parse.cc file:
parse.cc:462:10: fatal error: parse.hh: No such file or directory
462 | #include "parse.hh"
| ^~~~~~~~~~
Fix this by telling bison to output the header file to the correct
filename in the first place so that we don't have to rename it.
(using the --defines instead of -d option).
This looks like a bison specific option not available in Posix yacc;
but looks like we're requiring bison anyway.
