This patch fixes a few compilation warnings introduced by the
enumeration code. It also updates the ivl.def file so that the
proper routines get exported under windows.
Using reg real [1:0] var you can define a real variable with a
range. This was crashing the run time. This patch catches this
in the compiler and prints an appropriate message.
This gets the enumeration type through to the ivl_target API so
that code generators can do something with it. Generate stub
output with tgt-stub, and generate the proper vvp run time to
make simple enumerations work from end to end.
With warnings turned sufficiently high in gcc, I get:
.../vpi_user.h:568: warning: function declaration isn't a prototype
when building VPI modules. Patch is trivial.
At the moment we only support one real driver. This patch adds a
combined error routine for a uwire or a real net with multiple
drivers. We display the top level net in the hierarchy. It also
reworks the nexus data_type calculation.
System tasks and functions can be defined to have NULL arguments.
This patch makes the @* sensitivity list calculation skip these
NULL (constant) arguments.
This patch adds asserts after new to verify that memory was allocated
correctly and adds a warning if some of the routines are called with
an invalid function name.
Create the v2009.vpi module to include SystemVerilog core
functions, and start out with some of the enum methods.
Add to vvp support for creating enum types, including some
vpi access methods.
The pform propagates the parsed enum base type information
to the elaborator so that the base type can be fully elaborated.
This is necessary to get the types of the enumeration literals
correct.
This patch covers more than it should. It removes many of the -Wextra
warnings in the main ivl directory. It also makes some minor code
improvements, adds support for constant logicals in eval_tree (&&/||),
adds support for correctly sign extending === and !==, it starts to
standardize the eval_tree debug messages and fixes a strength bug
in the target interface (found with -Wextra). The rest of the warnings
and eval_tree() rework will need to come as a second patch.
The files we get from GTKWave are not under our control so we need to
ignore the cppcheck style warnings for them. The random routines are
from the standard so they should not be changed to fix style warnings
either. We also have some weird, but correct pointer subtraction that
cppcheck warns about. This patch adds suppression files for all these
warnings. You must have the latest cppcheck from git since I submitted
a patch that adds the ability to place comments in the suppression file.
In ivl_alloc.h we redefine malloc(), realloc() and calloc() to have
standard error checking. We don't want to do this for anything that
comes from the standard headers. This specifically doesn't work if
a C++ header files does std::malloc, etc.
Also change to -W instead of -Wextra since that is more portable. I
plan to add a check from -Wextra and use it when available since it
is more descriptive.
This patch changes all the iterator code to use a prefix ++ instead
of postfix since it is more efficient (no need for a temporary). It
is likely that the compiler could optimize this away, but lets make
it efficient from the start.
When enum names are used as r-values in expressions, use their
values. Treat the enum names similar to (but not exactly as)
localparams so that they fit into the rest of the elaboration
flow naturally.
