Webb8 juli 2024 · SimplifyCFG does some common code hoisting, which is limited to hoisting a sequence of identical instruction in identical order and stops at the first non-identical instruction. This patch allows hoisting instruction pairs over same-length sequences of non-matching instructions. Webb// cared about the global view once simplifycfg (and instcombine) have: 1858 // completed - it takes into account PHIs that become trivially: 1859 // simplifiable.
