When checking with valgrind clean up the following:
The arguments for invalid task/function calls.
The simulation callback queues (only needed when the runtime aborts).
Call pthread_exit(NULL) just before exiting to cleanup dynamic loading.
The vvp_darray_real class cal be used for static arrays as well
and this is a more general solution anyhow. Kill the now useless
vvp_realarray_t class.
This provides the ivl_target.h interface for class definitions
and expressions, the vvp code generator support for class objects
and properties, and the vvp run time support. Trivial class objects
now seem to work.
Create stub class objects at the vvp level and generate the code
to invoke that stub. Implement the routines needed to implement
a test for null object references.
This will hopefully improve performance slightly, but also this
intended as a model for what to do when I get around to doing the
same thing to other data types.
Strings, when put into dynamic arrays, are treated as first class
types much line reals. Add the code generator and vvp support for
this situation. Also fix a bug distinguishing between character
selects from strings and select form arrays of strings.
This involves working out the code to get the base type of a select
expression of a darray. Also added the runtime support for darrays
with real value elements.
Clean up the vector4_to_value to use templates and explicit
instantiations. This makes the interface much cleaner for a
wider variety of integral types.
This patch updates the vvp code so it will compile with the valgrind hooks
again. There are still new constructs that need to be cleaned up correctly
and some old constructs were changed enough that the old code no longer
works, but the rest of this can be done as an incremental improvement.
Windows and hence mingw does not follow the standard regarding the return
value of vsnprintf(). The mingw code needs to iteratively search for a
buffer large enough to print the output.
The second call to vsnprintf() needs to have a copy of the argument list
so it can run correctly. On some system vsnprintf() destorys the original
argument list.
When sending a string to a system task/function allocate the space needed
to avoid truncating the string vs using a large fixed buffer.
In vvp allocate and use an exactly sized buffer for the MCD print routine if
the fixed buffer is not large enough. Using a fixed buffer keeps normal
printing fast.
