question about testing arrays

[Venkatachalam, Vasanth]

Hi Thomas,

I tried running the following similar test case inside BasicPTXTest:

@SuppressWarnings("all")
     public static int arraysquares(int array1[]) {

     return array1[0];

 }
When I run this in PTX mode, I get the error below. Can you explain how to get past this in PTX?
I was initially seeing the same error in HSAIL until I implemented the Guard instruction, at which point I got the "ICMP receiving a constant" error alluded to earlier.

No, the issue is caused by the operand to the compare instruction not expecting a constant but a register. This is why I was asking you if an operand to an HSAIL compare instruction may also be a constant directly? Or does HSAIL require the constant be loaded into a register first?
