Do I understand correctly, that you propose to do so:
extern void *_omp_host_func_table[];
extern void *_omp_host_var_table[];
extern void *_omp_host_funcs_end[];
extern void *_omp_host_vars_end[];
void *__OPENMP_TARGET_HOST__[]
__attribute__ ((visibility ("protected"))) =
{
&_omp_host_func_table, &_omp_host_funcs_end,
&_omp_host_var_table, &_omp_host_vars_end
};
extern void *__OPENMP_TARGET_MIC__[];
extern void *__OPENMP_TARGET_PTX__[];
extern void GOMP_offload_register_host (const void *);
extern void GOMP_offload_register_target (const void *);
__attribute__ ((constructor))
static void
init (void)
{
GOMP_offload_register_host (__OPENMP_TARGET_HOST__);
GOMP_offload_register_target (__OPENMP_TARGET_MIC__);
GOMP_offload_register_target (__OPENMP_TARGET_PTX__);
}
Where __OPENMP_TARGET_MIC__ and __OPENMP_TARGET_PTX__ descriptors
should be generated in the corresponding mkoffload tools.
