update to verilog-current-20010113
bug fixes and signed support (yay!).
detailed changes since last packaged snapshot from the
authors announcements:
Icarus Verilog snapshot 20010113
--------------------------------
We're getting close to release candidates. Maybe another snapshot, then
I start with making 0.4 release candidates. So lets get this tested so
that I can move forward!
This snapshot largely fixes a whole bunch of bugs. I'm working feverishly
to catch up to the reported bugs, but they are coming in about as fast
as I can resolve them. (Not that I'm complaining, mind you. These PRs
are really helping me make it better.) But that means I'm going to just
concentrate on getting as many PRs done as I can before the release.
The syntax of functions and tasks has been expanded to allow parameters.
This is not a common thing to do, but someone puts parameters if functions
The syntax of functions and tasks has been expanded to allow parameters.
This is not a common thing to do, but someone puts parameters if functions
so I had a PR to fix:-) Also I caught a problem with executing functions
that take no input parameters. In fact, a bunch of function related bugs
were fixed. I lost track of em all.
Ports of tasks weren't elaborated properly. I fixed this and a few related
problems so most legal l-values should work as task port expressions now.
Memories within tasks should also work properly now.
Speaking of ports, I now report errors when there is a port direction
for module ports that don't exist. In fact, there are a whole bunch of
cases where I've added required error messages.
The %d format of display strings now displays signed negative values as
negative values instead of the unsigned equivalent. This goes along with
the other signed arithmetic features from the -2000 standard that are now
supported.
I fixed up the Makefiles (thanks to a contribution) to support build using
the VPATH capabilities of the makefile. You should be able to compile for
multiple targets now from a shared source directory.
Icarus Verilog snapshot 20010106
--------------------------------
I'm just managing to barely keep up with the bug reports arriving in
the bug tracking system. I'm pleased with the success of the ivl-bugs
robot. These bug reports have allowed me to better manage and record
progress. Keep those bug reports coming!
I've added support for arrays of integer and time variables, as well
as the Verilog 2000 initialization syntax for these types. I have also
made some internal changes to integer support. Integers are now just
a shorthand for ``reg signed [31:0]'' and signed variable support has
made some internal changes to integer support. Integers are now just
a shorthand for ``reg signed [31:0]'' and signed variable support has
been generalized. This makes it easier on the code generators, as they
do not need to know that a variable was a integer, a time, a foo or a bar.
I few constant propagation errors have been fixed. Continuous assignments
of constants to nets should behave correctly now.
Many people noticed lack of expression support for parameters. In fact,
the problem was a lack of support for a bunch of specific operators. I've
added many operators. This has the side effect of improving constant
propagation as well, in some cases finding more dead code to eliminate.
This also affected expressions that were index expressions of memories
and vector declarations.
The / operator in continuous assignment expressions is fixed. There were
a few size related issue here that are now fixed.
I've added to the i3331364-notes.txt file a clarification of my position
on parse of repeat statements. This position is compatible with XL behavior.
Passing parameters to user defined functions in behavioral code was pretty
darn broken. I managed to fix this. You can tell that not many people use
user defined functions:-) (It doesn't help that Icarus Verilog is picky
about them.)
For vvm, I've put some effort into optimizing the compile time of programs
by reducing the size of the output code. I've reduced redundancies some,
and used loops to handle vectors where possible.
A few bugs related to $dumpvars were cleaned up. Function scopes work.
