We present a polynomial-time algorithm which at the extra cost of a factor O(k) (k the number of variables) generalizes inter-procedural copy constant propagation. Our algorithm infers variable-variable equalities in addition to equalities between variables and constants. Like copy constant propagation, it tracks constant and copying assignments but abstracts more complex assignments and guards...

Ubiquitous mobile phones have transformed not just our modes of communication but self-perception. In facilitating a direct personal connection, be it via call, text message, or social media, they present the unprecedented challenge synchronicity, in which users must simultaneously navigate different contexts and plural identities. area Gilgit, northern Pakistan, young women particular struggle...
