Setting a conditional breakpoint

Is there any way to set a conditional breakpoint in the NIOS IDE tool. I would like to set a breakpoint during a condition within an if statement. For example for(i = 0; i < 0x1ffffff; i++)...

I have never tried setting a true conditional break point in Nios II IDE. However, a technique I have used before with many architectures is to simply add a NOP to your code with an IF statement on your condition. Then you can set a regular break point on the NOP.

So for your example, you could do something like:
for(i = 0; i < 0x1ffffff; i++)
{
    .
    .
    .
    if(i == 0x1000000)
        __asm__ volatile("nop");    <-- set break point here
    .
    .
    .
}
