119 formal void parameters added to keep -Wstrict-prototypes happy.
Process found one real missing prototype in vpi/vcd_priv.h:
EXTERN void vcd_names_delete(struct vcd_names_list_s*tab);
8 such warnings left, all in Tony's code
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.
Follow-up to "Brainless start to const-correct changes"
Still actually does nothing, but now if the #define ICARUS_VPI_CONST
in vpi_user.h is changed to const, Icarus is almost const-correct,
as checked with gcc flags -Wcast-qual -Wwrite-strings.
Choosing when to #define ICARUS_VPI_CONST const is left as an
exercise for the reader.
With these two patches applied, and the const define, there are
still about a dozen const problems left.
Results of running
cd vpi
for f in *.c *.h; do sed -i \
-e "s/_calltf(PLI_BYTE8/_calltf(ICARUS_VPI_CONST PLI_BYTE8/" \
-e "s/_compiletf(PLI_BYTE8/_compiletf(ICARUS_VPI_CONST PLI_BYTE8/" $f; done
and a trivial patch to vpi_user.h to, among other things, make
ICARUS_VPI_CONST blank.
Thus, this patch does absolutely nothing. Will be followed by a
(much shorter) patch that makes it do something. :-)
vpi_config.h defines _FILE_OFFSET_BITS. This must be defined before
any system includes files are processed, so vpi_config.h must be
called first. This patch puts vpi_config.h first. It also removes
direct calls for both vpi_config.h and vpi_user.h when sys_priv.h
is included since it already includes these two files.
It also updates the code to always include vpi_user.h using double
quotes.
This patch adds support for iterating over the list of vpiUserSystf
tasks/functions that have vpiUserDefn set. The vpiUserDefn property
is true by default, but you can call vpip_make_systf_system_defined()
to set this property false (will hide the vpiUserSystf object). All
the normal system tasks/functions have been modified to call this
procedure to remove them from the list of vpiUserSystf objects. Only
user defined system tasks or functions should appear in the list.
vpi_compare_objects() is just a simple are the two pointers the
same. This works correctly for the vpiUserSystf objects, but the
other handle objects have not been checked.
This patch cleans up the V-2005 and V-analog math functions to
free their allocated memory at the end of simulation. It also
modifies the veriusertfs code to do the same thing.
It also closes the VCD file at EOS.
This patch adds the constant system functions for Verilog-2005
and Verilog-AMS. These are evaluated at compile time. $abs(),
$min() and $max() support their polymorphic behavior in the
compiler where it really matters. They are always evaluated
as reals in the run time and the result/argument(s) will be
converted as needed.
The Verilog-2005 functions are available if using the 2005
generation (default) and if either the icarus-misc (also on
by default) or verilog-ams flags are set.
The Verilog-AMS functions are available if either the
icarus-misc or verilog-ams flags are set.
