Re: [Patch Ping] [RFC] Alias export patch

Can you add base numbers here, i.e. how many disambiguations are
there in total for a and x?
I do have the numbers on how many disambiguations (not necessarily new ones) the patch creates, if that's what you mean (see below). I don't have the numbers on how many disambiguations do the {true,write}_dependence in total, counting all the heuristics inside of those functions.

For the extended alias sets, the numbers of total and new disambiguations are always pretty close, for example (for SPEC) 11691 new out of 11801 total, or 10557 new out of 10775 total for bootstrap.

For the saved points-to sets, the new ones are only 1-3% of the total ones, for example for bootstrap 1948 new out of 70083 total, and for SPEC 1035 new out of 162099 total.
