Of course we should do this only if switch statements are expanded in an (almost?) optimal way. -- Summary: [tree-ssa] convert a sequence of "if"s to a "switch" statement Product: gcc Version: tree-ssa Status: UNCONFIRMED Keywords: pessimizes-code Severity: enhancement Priority: P2 Component: optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: kazu at cs dot umass dot edu CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14799
