Bug 21940 – Compiler flags -check=on/off not recognized

The help page for the -check=... flag lists on/off as a convenient shortcut to enable/disable all checks: dmd -check=? Enable or disable specific checks: =[h|help|?] List information on all available choices =assert[=[on|off]] Assertion checking =bounds[=[on|off]] Array bounds checking =in[=[on|off]] Generate In contracts =invariant[=[on|off]] Class/struct invariants =out[=[on|off]] Out contracts =switch[=[on|off]] Final switch failure checking =on Enable all assertion checking (default for non-release builds) =off Disable all assertion checking But those options are not recognized: dmd -check=on Error: Switch `-check=on` is invalid dmd -check=off Error: Switch `-check=off` is invalid
