Failed to build

Hi All!

I get the following error while compiling my CL file:

ERROR: Error: Cannot yet select: 0x858aae0: i64,flag = adde 0x858a8e0, 0x8581eb0, 0x858a9e0:1 [ID=53]

Any idea whats causing this?

Here is my code:

thanks in advance,

‘k’ is never set to anything in prog1. The compiler error is probably because of that.

But I gotta say, your iszero() function is awesome in it’s badness :slight_smile:

… try (all(u == 0)) instead. See section 6.12.6 of the specification for other possible functions.

You can also do ulong16 fpres = 0 to set every element to 0, you don’t need to set them individually.

The code itself is questionable anyway - e.g. every work item is working on the same global index. The point of global indices is that they should identify unique data so the work items do not conflict.
