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. :-)
The functions (malloc, free, etc.) that used to be provided in
malloc.h are now provided in cstdlib for C++ files and stdlib.h for
C files. Since we require a C99 compliant compiler it makes sense
that malloc.h is no longer needed.
This patch also modifies all the C++ files to use the <c...>
version of the standard C header files (e.g. <cstdlib> vs
<stdlib.h>). Some of the files used the C++ version and others did
not. There are still a few other header changes that could be done,
but this takes care of much of it.
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 is a major rework on the sys_fileio routines. They now have
improved compiletf routines and the calltf routines are now
standardized. Along the way a few bug were fixed as well. Some
updates to other vpi files as well.
I changed the order of the $fputc() arguments to match C and the
rest of the system functions like it ($fungetc, etc.). I recently
fixed $fungetc() so I'm assuming the $fputc() needs the same fix.
It's an Icarus specific function.
This patch cleans up some of the code to use common compiletf
routines where appropriate. It also adds code to print the
number of extra arguments and cleans up the messages a bit.
This patch cleans up the dump routines and adds file and
line number information for errors. It also adds some of
the missing MemoryWord properties so they can now be
dumped and monitored correctly.
This patch fixes a number of problems associated with the various dumpers.
1. It catches the problem uncovered in pr1809904 and prevents the core
dumps from happening. It prints a warning message if you try to change
the file after the program has started dumping data to the file.
2. It makes all the dumpers work in the same manner. Before the VCD
$dumpfile was processed at compile time, but the LXT/LXT2 versions
did this at run time. The correct place for this is the run time so
that you can pass the task a calculated name.
3. All the dumpers use common compiletf routines located in vcd_priv.c
4. Make the LXT/LXT2 $dumpfile commands only get the file name and
let $dumpvars actually open the file. This matches the VCD code.
5. Fix the $dumpfile code to allow calculated file names.
6. Make dumpvars without a scope/variable match all toplevel modules
not just the toplevel module the $dumpvars was located in. This
now matches the standard (2001).
7. Simplify the no dumper code (vcdoff.c) and add missing functions.
8. Cleanup the code and messages.
9. vvp can take -none for no dumper.
