Hello
When trying to compile a very simple OpenCL kernel.cl on a MIC device, I get the following error: LLVM ERROR: Non implemented constant type
Apparently, the source of the problem is the static array:
__constant _Complex double lookupTable_ipow_pos[4] = { 1, I, -1,-I };
The compilation of the same kernel and the execution on a CPU Xeon device works perfectly.
If I use double or int instead of _Complex double, it also compiles and runs fine, so this LLVM error is triggered exclusively by the _Complex double and the MIC device.
This is the kernel.cl:
#include <complex.h>
#include "ipown.h"
void kernel simple_add(global const _Complex double * A, global const _Complex double* B, global _Complex double* C){
C[get_global_id(0)]=A[get_global_id(0)]+B[get_global_id(0)] + ipown(get_global_id(0));
}
And this is ipown.h:
__constant _Complex double lookupTable_ipow_pos[4] = { 1, I, -1,-I };
inline _Complex double ipown( int n )
{
return lookupTable_ipow_pos[ n % 4 ];
}
Anyone is familiar with this issue?
Thanks in advance.
