Support of pipes

[L30nardoSV]

Hi, I have started using OpenCL2.0, and was hoping to check my application with oclgrind:

Kernel compilation flags:                 -cl-std=CL2.0                          

OCLGRIND FATAL ERROR (/home/jprice/oclgrind-testing/oclgrind/src/core/WorkItem.cpp:1723)
Undefined external function: __write_pipe_2
When creating kernel 'Krnl_GA'
Context callback: 
Oclgrind - OpenCL runtime error detected
	Function: clCreateKernel
	Error:    CL_INVALID_KERNEL_NAME
	Kernel 'Krnl_GA' not found

It seems pipes are not yet support, but I couldn't find this info in the documentation.
Could you please confirm this ? thanks!

That's correct - pipes are not yet supported. Oclgrind only supports a very small number of OpenCL 2.0 features at the moment.

Understood. Thanks!
