Prevent an overflow of command line flags if the -Wall argument
is used multiple times, and fix processing of individual flags
that may be in the beginning of the warnings flag buffer.
When user defined function calls are withing a $signed, the result
needs to be properly padded. To make this work, handle padding of
a function result exactly type the padding of a signal vector. this
is natural in that the function return value *is* in a signal vector.
This fixes pr1841300.
This patch fixes the calculation of the scope type in draw_scope.
This code is really only used in the VCD dumper so I commented it
out in the other two. The problem was that the lower scope was
used to calculate the scope type. It is also now an error to try
to draw an invalid scope type.
This patch fixes a number of problems associated with the various dumpers.
1. It catches the problem uncovered in pr1809904 and prevents the core
dumps from happening. It prints a warning message if you try to change
the file after the program has started dumping data to the file.
2. It makes all the dumpers work in the same manner. Before the VCD
$dumpfile was processed at compile time, but the LXT/LXT2 versions
did this at run time. The correct place for this is the run time so
that you can pass the task a calculated name.
3. All the dumpers use common compiletf routines located in vcd_priv.c
4. Make the LXT/LXT2 $dumpfile commands only get the file name and
let $dumpvars actually open the file. This matches the VCD code.
5. Fix the $dumpfile code to allow calculated file names.
6. Make dumpvars without a scope/variable match all toplevel modules
not just the toplevel module the $dumpvars was located in. This
now matches the standard (2001).
7. Simplify the no dumper code (vcdoff.c) and add missing functions.
8. Cleanup the code and messages.
9. vvp can take -none for no dumper.
This patch fixes another minor problem introduced by the process
end of simulation events. Specifically if the compilation has
indicated we should not run do not even start the main event loop.
Parse SDF file annotations of edge sensitive delay paths.
Add vpi support for getting the specified edge sensitivity of
an edge sensitive path, and annotate paths with proper attention
to the edge that is specified for the path.
When loading a part select from the least significant bits, it is
OK to use the %load/v instruction to strip the high bits off. This
allows the zero-based part select to work in one step, without
loading excess bits.
Some patch caused a variable that held the constant base of a part
select to become unassigned. This led to unexplained failures to part
select a signal. Fix by properly detecting the case of a constant base
of 0 for the part select.
The %ix/getv instruction loads an integer register directly from
a signal vector. This is an optimization that an index register
is loaded from an expression is only a signal. It avoids the thread
vector space.
Using the parser supplied error token to get file and line number
information appears to give incorrect results at best and core dump
at worst. This patch uses the closest real token that makes sense
to alleviate this problem.
Use the new array VPI functionality (vpiIndex, vpiParent, vpiArray)
to dynamically generate array word names. The old patch to implement
was mostly reverted.
Add the array related VPI calls. These will be used to generate
the array word name only as needed to conserve space. This patch
also makes scanmem3 from the vpi test work correctly after a
slight gold file update.
Where and expression is an immediate value added to a signal value,
it is possible to optimize them to a single instruction that combines
the load with an add at the same time.
The patch for adding support for macros with arguments contained
a leftover debugging aid. This patch corrects the code. It also
should eliminate some compilation warnings.
The functor counters were left over from the v0.8 release. Rework
the counters to be relevent to the current state of vvp.

This patch modifies the preprocessor to handle text macros with
arguments. It also fixes a bug that prevented a `line directive
being issued after a multi-line text macro had been instantiated.
The second argument of $sdf_annotate is the scope that is to be
annotated. The argument is optional, and the default is to annotate
the current scope, where the $sdf_annotate is invoked.

This patch adds a -D option to iverilog-vpi and updates the manual

Handle the special case that the SDF CELL instance is empty. In this
case, the SDF file is requesting the current scope instead of an
instance within the scope.

This patch adds the ability to dump array words. The words are only
dumped if they appear in a $dumpvars() statement (they are not dumped
by default). The name used for the word is <array_name>[<index>], so
you can get unexpected name conflicts.
There is also a slight increase in the memory requirements since each
array word now keeps its own name information. In the future we would
like to change this, but that is a much larger rewrite of the array
code in vvp.
This patch also needs the "Prefix escaped identifier ..." patch to
work correctly (the array word name is an escaped identifier).
Comparison operands are signed only of both operands are signed.
If one is unsigned, then they both are unsigned. This does not
affect the signedness of the comparison itself, which is unsigned.

The LXT and LXT2 formats ignore/work with duplicate variables in
$dumpvars() commands, but VCD output includes extra definitions that
may cause some confusion. This patch checks for duplicates and prints
a warning when they are being suppressed.
It also corrects some error messages in the LXT and LXT2 files to not
reference VCD and some other message cleanup.
The min/typ/max default warning was not being produced in all
locations a min/typ/max expression could be used. This patch
adds the default warning code to all locations. It also
modifies the manual page to explicitly state that only the
first ten warnings are printed.
