- Changed offload entry section name to “omp_offloading_entries”
- Wrapper bit-code now uses __start_ omp_offloading_entries/__stop_ omp_offloading_entries symbols for accessing offload entry table assuming that these symbols are defined by the linker
- Removed omptargetbegin.o/omptargetend.o objects
