Update header files to use a more standard name to prevent rereading This is from github report #16. There are likely a few more issues that need to be addressed though this takes care of the major ones.

/*
Add option to only warn about macro redefinitions that change the text. A common use case (prior to the introduction of localparam) was to use macros to define constant values, and to put global constant values in an include file that gets included by each source file. This will generate a lot of spurious warnings if we warn about all redefinitions. Make this new option the default for -Wall.

extern void reset_lexor(FILE*out, char*paths[]);
Fuss with C function prototypes 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

extern void destroy_lexor(void);
Supoprt precompiled defines 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.
2007-12-31 03:47:32 +01:00
extern void load_precompiled_defines(FILE*src);
Add support for text macros with arguments. 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.

Add VHDLPP support to ivlpp program The ivlpp program is a good place to detect that the source file is VHDL, and pass the source file to the vhdlpp program. Do so automatically.

/* Program to use for VHDL processing. */
extern char*vhdlpp_path;
Add +vhdl-work+ control to the config file. 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.
2011-07-25 00:24:32 +02:00

extern char*vhdlpp_work;
Add include path and line directives.
1999-07-03 22:03:47 +02:00
Add support for vhdl named libraries. Put libraries in a directory of libraries, support a search path of library directories, and read those libraries as needed.
2011-07-31 03:18:03 +02:00
extern char**vhdlpp_libdir;
extern unsigned vhdlpp_libdir_cnt;
Make the addition of the local directory optional (include path). 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.

Add dependency generation.

extern FILE *depend_file;
Provide different modes for dependency list output. 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.

ivlpp: Removed the unnecessary parser 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.
