Dear all,
I wrote a new pass for gcc. Actually the pass is always executed, but
I'd like to execute it only if I specify an option from shell (ex. gcc
--mypass pippo.c). How can I do?
Create a new flag in common.opt and read its value in the gate function
of your pass. I *believe* this is documented somewher in the internals
manual, but I'm not sure.
You can check how other passes do it. See, for instance,
flag_tree_vectorize in common.opt and in the vectorizer's gating predicate.
