This adds a -u option to the driver to allow the user to specify that
they want each source file to be treated as a separate compilation
unit, and modifies the compiler to accept a list of files (either on
the command line or via a file specified by a new -F option). This
list of files is then preprocessed and parsed separately, causing all
compiler directives (including macro definitions) to only apply to the
file containing them, as required by the SystemVerilog standard.
In ivl_alloc.h we redefine malloc(), realloc() and calloc() to have
standard error checking. We don't want to do this for anything that
comes from the standard headers. This specifically doesn't work if
a C++ header files does std::malloc, etc.
Also change to -W instead of -Wextra since that is more portable. I
plan to add a check from -Wextra and use it when available since it
is more descriptive.
This patch changes all the iterator code to use a prefix ++ instead
of postfix since it is more efficient (no need for a temporary). It
is likely that the compiler could optimize this away, but lets make
it efficient from the start.
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 spaces in the path to the temporary files.
Adds support for spaces in output files and in library paths.
A space in the installation path is only supported under MinGW
(windows) at this time.
This patch modifies the iverilog -M command line option to allow
the user to specify an optional output mode that controls which
files get added to the dependency list. This allows the user to
either get a list of all files that contribute to the design,
or a list of the include files, or a list of the module files.
The dependency file may be written by ivlpp as it loads its own
dependencies. Make sure this doesn't mess up the dependencies that
are already written by the main program. This requires that ivl,
ivlpp and iverilog (driver) cooperate on the opening of the
dependency file.
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.
