Hi, all I would like to add a new pass into gcc (cc1 in my case particularly) and want to add a new command line option to turn it on/off. After looked couples of examples from previous patches, I tried to add new options in "common.opt". It added new option for me but every time I make a change to "common.opt", it will cause the whole gcc recompiled and thus, takes a very long time. Is there any other way I can add a new option but without going through the recompilation? Thanks Haifeng
