clGetKernelArgInfo functions

[trbauer]

These are OpenCL 1.2. This would entail adding:

clGetKernelArgTypeName :: CLKernel -> Int -> IO String
clGetKernelArgName :: CLKernel -> Int -> IO String
clGetKernelArgAddressQualifier :: CLKernel -> Int -> IO CLKernelArgAddressQualifier
clGetKernelArgAccessQualifier :: CLKernel -> Int -> IO CLKernelArgAccessQualifier
clGetKernelArgTypeQualifier :: CLKernel -> Int -> IO CLKernelArgTypeQualifier
And the enumerations for the latter 3.
data CLKernelArgAddressQualifier =
CL_KERNEL_ARG_ADDRESS_GLOBAL
| ...
... etc

I wouldn't mind implementing this and setting up a pull request (this would be my first).

Hi, I thinked about it some time ago, and maybe the best way its to make a branch for OpenCL 1.2 instead of merge it on the main branch.

So, we can always generate 1.0.X packages for the people doesn't have 1.2 drivers.

Thanks

Why not retain one branch only, but can we include a preprocessor flag (cabal) option to include or omit 1.2 stuff. This would make validation and maintenance more uniform (don't have to keep two branches in sync). In addition, I don't want all of 1.2, just a few functions at the moment. A 1.2 branch or sort of implies that we support and validate everything right?
