| Summary | 0000578: Switch detection regression | ||||
| Description | After commit c9e549996 ("Let switch detection handle deeper disjunctions."), the compiler no longer accepts the given test case. % mmc -e switch_detection_regression.m switch_detection_regression.m:017: Error: the determinism declaration for switch_detection_regression.m:017: predicate `halign'/5 is not satisfied. switch_detection_regression.m:017: Declared `det', inferred `nondet'. switch_detection_regression.m:017: The reasons for the difference are the switch_detection_regression.m:017: following. switch_detection_regression.m:029: switch_detection_regression.m:029: Unification of `Dir' and switch_detection_regression.m:029: `switch_detection_regression.ltr' can switch_detection_regression.m:029: fail. switch_detection_regression.m:031: switch_detection_regression.m:031: Unification of `Dir' and switch_detection_regression.m:031: `switch_detection_regression.rtl' can switch_detection_regression.m:031: fail. switch_detection_regression.m:032: switch_detection_regression.m:032: Inside the case end/0 of the switch on switch_detection_regression.m:032: TextAlign: switch_detection_regression.m:032: disjunction has more than one disjunct switch_detection_regression.m:032: with solutions. switch_detection_regression.m:041: switch_detection_regression.m:041: This later disjunct may have a solution. switch_detection_regression.m:032: switch_detection_regression.m:032: Inside the case start/0 of the switch on switch_detection_regression.m:032: TextAlign: switch_detection_regression.m:032: disjunction has more than one disjunct switch_detection_regression.m:032: with solutions. switch_detection_regression.m:041: switch_detection_regression.m:041: This later disjunct may have a solution. switch_detection_regression.m:038: switch_detection_regression.m:038: Unification of `Dir' and switch_detection_regression.m:038: `switch_detection_regression.ltr' can switch_detection_regression.m:038: fail. switch_detection_regression.m:040: switch_detection_regression.m:040: Unification of `Dir' and switch_detection_regression.m:040: `switch_detection_regression.rtl' can switch_detection_regression.m:040: fail. | ||||
