[mat-dev] Dominator tree/retained size computation

[Himanshu Vashishtha <himanshuv@xxxxxxxxxxxxxxx>]

Hello Devs,

Is it possible to have some info on how MAT computes the dominator tree and subsequently the retained size of objects. I do see it does multi pass on the dump and creates multiple index files — but couldn’t find any doc/info as to how it computes the tree/retained size. 

(In case if reading code is the only way, a high level info will be helpful :))

Thanks,

Himanshu
