119 formal void parameters added to keep -Wstrict-prototypes happy.
Process found one real missing prototype in vpi/vcd_priv.h:
EXTERN void vcd_names_delete(struct vcd_names_list_s*tab);
8 such warnings left, all in Tony's code
Presumably, the user will want the ability to explicitly set the
working library location, so create a +vhdl-work+ plusarg setting
for exactly that purpose.
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.
In the past we automatically added the local directory to
the beginning of the include search path. This was found to
conflict with what other tools do so this functionality is
now only available when the -grelative-include option is
given to iverilog.
This patch fixes a minor memory leak in ivlpp and releases all
dynamically allocated memory before the program exits. Other than
the dynamically allocated push state buffer in flex, ivlpp has no
valgrind memory errors or warnings.
The verilog preprocessing language is sufficiently simple
that the parser may be implemented by hand on top of the
lexical analyzer.
In fact, ivlpp was already implemented in this way; relevant
[bison] parser files specified no grammar, and the parser
entry-point (yyparse) was simply an indirect use of the lexical
analyzer (yylex).
Therefore, parse.y has been removed, invocations of yyparse()
have been replaced by yylex(), references to bison generated
files have been removed, and Makefile.in has been updated
accordingly.

Core preprocessor support for writing out and reading precompiled
defines. The preprocessor can read initial precompiled defines from
any number of specified source files, and can write all the defines
into a specified output file.
This patch modifies the preprocessor to handle text macros with
arguments. It also fixes a bug that prevented a `line directive
being issued after a multi-line text macro had been instantiated.
