[Starpu-devel] setting the clBuildProgram() option parameter

[Jonathan Adamczewski <jadamcze@utas.edu.au>]

clBuildProgram() is called within 
starpu_opencl_load_opencl_from_string() with a hard-coded options 
parameter of "-Werror -cl-mad-enable". I would like to be able to 
set different options, such as include paths and macro definitions 
for the opencl kernels I am using with starpu.

If I were to add support for different option strings, what would be 
an appropriate/preferred way to do so? Options I can see are:
 - extra parameter passed to the function (which needs to be added 
to other functions, too)
 - extra const char* field in struct starpu_opencl_program (one 
option for all opencl programs)
 - array of const char* fields in struct starpu_opencl_program, one 
for each program
 - environment variable

Thanks

Jonathan.
