It's a little hard to know the best approach with no idea of what kinds of rules you are talking about. However, given that.... Using -W options is the right approach. I don't see any reason why -Wno-analyze-Rule=<rule number> wouldn't work. Probably better would be -Wanalyze-all and -Wanalyze=RULE,RULE,RULE and -Wno-analyze=RULE,RULE,RULE where the rules have names. While I don't speak for all the gcc maintainers, I think it's very unlikely that we would a -Wanalyze option which took rule numbers, unless the numbers refer to a standard reference work along the lines of the -Weffc++ option. > 1.

You would need to make a very strong argument for adding a new kind of option to gcc. Perhaps the nature of the rules you are talking about makes this the right approach. However, based on what you've said so far, these sorts of option names would be inappropriate. Ian
