           Summary: Optimize IL code emitted on binary `|' operator
           Product: Mono: Compilers
           Version: unspecified
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: C#
        AssignedTo: mono-bugs at lists.ximian.com
        ReportedBy: msafar at novell.com

          Found By: ---

We emit pretty bad code for `x | (true|false)' binary boolean operations. This
is more visible when used together with nullable types.

public static class D {

        static bool? debugging = null;

        public static void Main () {
            debugging |= true;


The fix is to extend binary optimizations currently done in Binary::DoResolve.
