The name is not currently used, but when it is it makes sense for it to
be in the base class. Also the name cannot be deleted after compiling
since it may be used later.
This patch adds -Wextra to the compilation flags for C++ files in
the vvp and vpi subdirectories. It also fixes all the problems
found while adding -Wextra. This mostly entailed removing some of
the unused arguments, removing the name for others and using the
correct number of initializers.
This patch adds a few missing initializations to various constructors
in the vvp directory. It also enhances the array alias code to copy
more values from the aliased array.
This patch adds support for a UDP with variable delays. In the process the
intrinsic support for delays was removed from the UDP functor and replaced
with a call to the .delay functor. Both a normal gate and a UDP now use the
same code to generate the delay.
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.
This patch adds code to free most of the memory when vvp
finishes. It also adds valgrind hooks to manage the various
memory pools. The functionality is enabled by passing
--with-valgrind to configure. It requires that the
valgrind/memcheck.h header from a recent version of
valgrind be available. It check for the existence of this
file, but not that it is new enough (version 3.1.3 is known
to not work and version 3.4.0 is known to work).
You can still use valgrind when this option is not given,
but you will have memory that is not released and the
memory pools show as a single block.
With this vvp is 100% clean for many of the tests in the
test suite. There are still a few things that need to be
cleaned up, but it should be much easier to find any real
leaks now.
Enabling this causes a negligible increase in run time and
memory. The memory could be a problem for very large
simulations. The increase in run time is only noticeable on
very short simulations where it should not matter.
Remove the #ident and $Log$ strings from all the header files and
almost all of the C/C++ source files. I think it is better to get
this done all at once, then to wait for each of the files to be
touched and edited in unrelated patches.
