Windows Vista, ATI SKD2.2, Driver 10.7b, Vis Studio 2008
all with current updates
I have Vis Studio set up to run the OpenCL compiler as part of the build process and I get a clean compile. When I call clBuildProgram, however, I get an error -
"atomic_xchg" declared implicitly.
The program contains
int4 link;
int4 src = ....;
int foo = ...;
atomic_xchg(&q[src.x], foo);
and q is an input parameter __global int * q
Why does it compile outside my program, but not called from within? Could I somehow be calling the OpenCL 1.0 rather than 1.1 compiler somehow? I uninstalled everything along the way to installing 2.2, so I don't see where the old compiler would come from.
I've searched my hard disk and have only one file named clc.exe, dated 8/9/2010, 12:34PM. Is this what gets called by clBuildProgram?
Also, I notice that the openclsdk_.vsprops files have changes the paths where to look for the various .lib files. I can replace my old copies of this file with the new, but the change doesn't seem to impact the project settings.
drstrip,
are you able to run the samples.If yes plz send the Output of clInfo sample.

I ran clInfo and I immediately saw what you were driving at. For the target device I get -
Version: OpenCL 1.0 ATI-Stream-v2.2 (302)
ie, OpenCL 1.1 is apparently not supported on this device (a Firestream 9270), nor is it supported on my other device, a FirePro 3750.
So the next question is - will these devices ever be supported at the 1.1 level, or does the hardware not permit it?
This page - http://developer.amd.com/gpu/ATIStreamSDK/Pages/default.aspx - lists both of my devices as being supported by SDK 2.2 and makes no mention that any devices are not supported at the OpenCL 1.1 level.
Presumably that means there is no way to do any sort of atomic operation on these devices. Right?
