Hi, I would like to send a gcc-frontend tracer and a perlscript called htmltags.pl that takes the trace and creates a nice dhtml page. The source is here: http://cfw.sourceforge.net/htmltags.html an example of the output is here: http://cfw.sourceforge.net/htmltag/init_32.c.pinfo.html There is a helptext on the left side pannel. Maybe somebody want to rewrite it so that such a feature appears sometimes in a future gcc... The principle is like http://lxr.linux.no however htmltags.pl offers total visibility of the preprocessor domain (try expand macros in init_32.c.pinfo.html like descrbed in the left help-panel). htmltags.pl is little bit of a brute forcer, generating init_32.c.pinfo.html takes aroung 2 min and it generates 50mb html... -- Greetings Konrad
