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
Some of the SDF warnings were mixing some of the scope path with the
instance name. These are now separated into just scope and instance name.
There was also a place where vpi_get_str() was being called twice in a
single print statement. This is illegal since vpi_get_str() uses a single
buffer and multiple calls will overwrite the buffer.
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. :-)
A real delay must be scaled and rounded using the local precision
before it is finally scaled to the simulation time units. This
patch fixes the compiler to do this correctly or generate the
correct code for run time calculated delays. Delays in a CA
already worked correctly. The run time was also fixed to scale
modpath (SDF back annotation) delays correctly.
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 adds compilef routines for the readmemb/h and
writememb/h system tasks. It also fixes some errors related
to arrays with negative range values. You can not specify a
negative address in the file, but arrays with negative range
values or negative start/finish argument to the tasks are
supported. It also generates an error when reading invalid
character from the input file.
A significant amount of the code is common between the two
styles of tasks so this has been grouped into common
routines.
It also adds a common routine for getting a string that will
be used as a file name. This routine is used by any task
that requires a file name value. If a filename has a
non-printable character it will be displayed as a \octal
constant to show what the character is.
Updates the dumping routines to match each other better,
improves some error messages and fixes a bug in the LXT2
dumper when dumping greater than 32 bit delays.
This patch adds support for the other edges 01, 10, etc. These still
need to be verified in the context of IOPATHs, but they are ignored
in the timing checks and that's what was needed.
This patch updates the compiletf for $sdf_annotate() to better
check the arguments and to display the file and line location
when an error/warning does occur. It does the same for the
calltf messages. It also fixes a couple of subtle bugs.
First we need to look for a NULL string not a NULL value. The
result buffer should always be defined so will never be NULL.
Next if a scope has no modules we should return like the module
was not found (return 0) vs asserting.
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.
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.

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.

Implement extended vvp command line options to control the amount
of detail that the sdf annotator emits while parsing the source
file.
