cl_platform.h vendor dependency?

e.g. cl_float4.f32[] vs. cl_float4[]

Hello everybody,

I'd like to ask if anyone else has tried to run his/her host code on another platform besides AMD/ATI-Stream. It seems typedefing cl_float4 to the union containing f32[] is not done by other vendor's cl_platform.h (namely: NVIDIA), so I had a look at the "official" Khronos cl_platform.h -- it's not in there, either!

Take for example AMD's cl_platform.h, line 244:

 

typedef union cl_float4   { cl_float  f32[4]; }  cl_float4;


and compare with Khronos' cl_platform.h, line 117:

 

typedef float           cl_float4[4];


Ergo: Host code will not compile on platforms other than ATI-Stream. Which is regrettable, to say the least.

So:

 

  • if you encountered this, did you find a workaround (maybe some #defines here and there..., I tried #define .f32  but that didn't work) ? 
  • Will AMD change this in future releases?


Disclaimer: I'm using the C++ bindings provided by Khronos, and I'm astounded by the significant speed ups of even the CPU implementation! Thumbs up for that, AMD/ATI!
