sccp

Overview ¶

Package sccp implements sparse conditional constant propagation for golang.org/x/tools/go/ssa. It is a faithful adaptation of the Go compiler's implementation in cmd/compile/internal/ssa/sccp.go; the algorithm, structure and comments follow the original closely, with only the necessary changes to map the compiler's value-based IR (Op/AuxInt) onto go/ssa's instruction-based IR (token.Token/constant.Value).
