Two fixes needed:
- when searching for a base class, we need to look in the root scope
if the base class isn't found in the scope hierarchy
- the classes in the root scope need to be stored in an ordered
list, not a map, to ensure they are elaborated in the order they
were declared. Without this, the compiler may try elaborating an
extended class before its base class is known about.
(cherry picked from commit 87cddf33dc)
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 support for the `resetall directive.
It also changes `celldefine, `endcelldefine and `resetall
to no longer grab text following them. These directives do
not take an argument so they should not be grabbing any
text and silently discarding it.
The `timescale processing was reworked to handle being
reset and hooks were added to easily change the default
time units and precision when we add that feature request.
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.
