Run the following code on x86 Mono, e.g. on Android:
float resultF = Add(1.0f, 2.0f);
double resultD = Add(1.0, 2.0);
Console.WriteLine(resultF);
Console.WriteLine(resultD);
static T Add<T>(T left, T right) where T : struct
{
unchecked
{
if (left is short) return (T)(ValueType)(short) ( (short) (ValueType)left + (short) (ValueType)right );
else if (left is int) return (T)(ValueType)(int) ( (int) (ValueType)left + (int) (ValueType)right );
else if (left is long) return (T)(ValueType)(long) ( (long) (ValueType)left + (long) (ValueType)right );
else if (left is ushort) return (T)(ValueType)(ushort) ( (ushort)(ValueType)left + (ushort)(ValueType)right );
else if (left is uint) return (T)(ValueType)(uint) ( (uint) (ValueType)left + (uint) (ValueType)right );
else if (left is ulong) return (T)(ValueType)(ulong) ( (ulong) (ValueType)left + (ulong) (ValueType)right );
else if (left is byte) return (T)(ValueType)(byte) ( (byte) (ValueType)left + (byte) (ValueType)right );
else if (left is sbyte) return (T)(ValueType)(sbyte) ( (sbyte) (ValueType)left + (sbyte) (ValueType)right );
else if (left is float) return (T)(ValueType)(float) ( (float) (ValueType)left + (float) (ValueType)right );
else if (left is double) return (T)(ValueType)(double) ( (double)(ValueType)left + (double)(ValueType)right );
else throw new NotImplementedException();
}
}It crashes with this runtime assert:

I saw that x86 is the only platform where we define MONO_ARCH_USE_FPSTACK to true, that's why we only see it there.
