          Issue ID: 14767
           Summary: BigInt compile time errors
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: paul.d.anderson at comcast.net

The following code fails to compile and responds with the given error message.
Varying the "plusTwo" function doesn't work; as long as there is an arithmetic
operation the error occurs.

It seems to mean that there is no way to modify a BigInt at compile time. This
seriously limits the usability of the type.

enum BigInt test1 = BigInt(123);
enum BigInt test2 = plusTwo(test1);

public static BigInt plusTwo(in BigInt n)
{
    return n + 2;
}

void main()
{
}

Error message:

C:\D\dmd2\windows\bin\..\..\src\phobos\std\internal\math\biguintx86.d(226):
Error: asm statements cannot be interpreted at compile time

Error occurs with dmd 2.067.1 for 32-bit Windows. Does not occur with Windows
64-bit version
