User [EMAIL PROTECTED] added comment https://bugzilla.novell.com/show_bug.cgi?id=400014#c324675 Summary: Intrins Math.Max and Math.Min incorrect for uint Product: Mono: Runtime Version: 1.9.0 Platform: x86 OS/Version: Windows XP Status: NEW Severity: Major Priority: P5 - None Component: JIT AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] QAContact: [email protected] Found By: Third Party Developer/Partner Created an attachment (id=222024) --> (https://bugzilla.novell.com/attachment.cgi?id=222024) Test exposing incorrect uint Math.Min and Math.Max intrinsic (I'm actually testing in the 1.9.1 release, which appears to not be in the list of versions. This is very similar to bug #324675, but this is for uints and bug #324675 isn't present in my version.) Given the following code (also attached): uint a = (uint)int.MaxValue + 10; for (uint b = 7; b <= 10; ++b) { Console.WriteLine("Max(" + a + "," + b + ") = " + Math.Max(a, b)); Console.WriteLine("Max(" + b + "," + a + ") = " + Math.Max(b, a)); Console.WriteLine("Min(" + a + "," + b + ") = " + Math.Min(a, b)); Console.WriteLine("Min(" + b + "," + a + ") = " + Math.Min(b, a)); Console.WriteLine(); } Incorrect output from mono baduintminmax.exe: Max(2147483657,7) = 7 Max(7,2147483657) = 7 Min(2147483657,7) = 2147483657 Min(7,2147483657) = 2147483657 Max(2147483657,8) = 8 Max(8,2147483657) = 8 Min(2147483657,8) = 2147483657 Min(8,2147483657) = 2147483657 Max(2147483657,9) = 9 Max(9,2147483657) = 2147483657 Min(2147483657,9) = 2147483657 Min(9,2147483657) = 9 Max(2147483657,10) = 2147483657 Max(10,2147483657) = 2147483657 Min(2147483657,10) = 10 Min(10,2147483657) = 10 Correct output from mono --optimize=-intrins baduintminmax.exe Max(2147483657,7) = 2147483657 Max(7,2147483657) = 2147483657 Min(2147483657,7) = 7 Min(7,2147483657) = 7 Max(2147483657,8) = 2147483657 Max(8,2147483657) = 2147483657 Min(2147483657,8) = 8 Min(8,2147483657) = 8 Max(2147483657,9) = 2147483657 Max(9,2147483657) = 2147483657 Min(2147483657,9) = 9 Min(9,2147483657) = 9 Max(2147483657,10) = 2147483657 Max(10,2147483657) = 2147483657 Min(2147483657,10) = 10 Min(10,2147483657) = 10 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
