Any future plan to support the atomic_* data types and their related API functions?

Hi all,

Despite enabling required extensions on the .cl file (like below lines), I get an error at the run time.

Enabled extensions in .cl file:

#pragma OPENCL EXTENSION cl_khr_int64_base_atomics : enable
#pragma OPENCL EXTENSION cl_khr_int64_extended_atomics : enable

Output from Oclgrind:

OCLGRIND FATAL ERROR (/home/user1/Oclgrind/src/core/WorkItem.cpp:1731)
Undefined external function: atomic_exchange
When creating kernel 'kernel1'

I have enabled -cl-std=2.0 when compiling/building kernels.

Here is the list of supported extensions in my output.

cl_khr_spir
