If both the async. clr and set pins clear a flip-flop then we need to
create an OR gate to combine the two signals to connect to the single
DFF clr pin. This patch fixes the tgt-vvp code generator to implement
this functionality.
This patch removes #ident since it is deprecated in recent gcc
versions. It also removes all the CVS comments and fixes a few
other compilation warnings. There are still a few compilation
warnings, but this takes care of most of them. Fixing the rest
will require a bit more thought.
System tasks and functions can be defined to have NULL arguments.
This patch makes the @* sensitivity list calculation skip these
NULL (constant) arguments.
This check could be useful, but it was making make check fail
since it was before base was redefined by -B. This check is
not in V0.9, so it was easier to just remove it from V0.8. This
would only happen if <path>/lib/ivl-0.8/ivl did not already
exist (on a pristine system).
Using auto_ptr in elab_net.cc (added in commit 15702f1, "Fix bad
memory reference." on 2008-11-28) requires #include <memory> when
compiling with gcc-4.3.
This is a back port from development of the code to put and check
that the vvp input file is the right version. It also adds the -V
flag to vvp. It does not add the VERSION_TAG information so will
only produce the single string ivl_version tag. The runtime will
read both forms since if it is feed a V0.9 file we want it to
complain nicely (no syntax error). To change the displayed version
for the various programs and checks change version.h.
This is a back port from development of the code to resize an
unsized constant value to 32 bits. Development used integer_width,
but that is not supported in V0.8. Development also supports using
the expression width which V0.8 does not.
This patch mirrors what was done in development to fail for zero
width repeats. Actually development supports them in some contexts,
this is allowed in 1364-2005, but V0.8 doesn't support them at all.
Users expect that vpi_put_value() will keep a copy of the string
that is passed to it. This patch implements this buy copying the
string and then freeing it after the actual put_value call.
This configure option causes the installed commands to have
a suffix string that makes them distinct from other versions
that also have a suffix string. This allows for multiple
installed versions of Icarus Verilog.
Also, move installed C/C++ header files into a subdirectory of
their own under the target include directory, to make clearer
the purpose and source of those files.
(cherry picked from commit 4bc90f7cfd)
There was an error when calculating the negative of a value that
was the same width as the native machine word. This patch is similar
to what was done in 0.9 to fix the problem there.
This patch fixes the verinum < and <= operators to directly
compare the long result not the difference. Because of overflow
the difference can give an incorrect value. Using a long value
is technically wrong, but that will need to be a different
patch. It also fixes the eval_leeq_() routine to correctly build
the largest value in a signed comparison.
