Alan Donovan 8f1fdf33de go.tools/ssa: opt: improve the "unused φ-node" check to eliminate self-refs, debug-refs. ... This removes about 5% of φ-nodes in one large program and eliminates many zero-value constants. (This does cause some Idents to no longer map to an ssa.Value. This is observable in the oracle, whose tests are here updated.) R=gri, gri CC=golang-dev https://golang.org/cl/26980043		2013-11-21 14:19:38 -05:00
