Hello, All
I have a simple kernel which makes open cl api to crash on
clBuildProgram();
i call it lioke this:
clBuildProgram(program, 1, device, 0, NULL, NULL); // <- crash occures inside this call. somewhere inside aticaldd.dll
This crash happens only if i build my program in Release mode.
However KernelAnalyzer2 also can't build this kernel. It just can't finish to build it.
I suppose that crash occures somewhere at the code generation stage, because if i make mistake in the kernel - there is no crash.
I have Catalyst 12.8
Here is the kernel itself:
#pragma OPENCL EXTENSION cl_khr_byte_addressable_store : enable
#define pixel uchar
struct _OCL_BUF_INFO {
int i_mb_width;
int i_mb_height;
int i_stride;
float qp;
} ;
typedef struct _OCL_BUF_INFO OCL_BUF_INFO;
__kernel
//__attribute((reqd_work_group_size(64,1,1)))
void testKernel(
__global const pixel* fenc_plane,
OCL_BUF_INFO h,
__global uchar* dbgout)
{
const size_t li = get_local_id(0);
const int xy = li % 16;
//uchar fenc[16] = {0};
uchar16 fenc;
fenc = vload16(0, fenc_plane );
for(int i=0;i<16;++i)
dbgout[i + 16*xy] = ((uchar*)&fenc); // this line causes issue, if i'll change fenc type to: uchar fenc[16] everything is ok.
return;
}
