[PR libgomp/64625] Remove __OFFLOAD_TABLE__ variable/formal parameter.
gcc/ * omp-low.c (offload_symbol_decl): Remove variable. (get_offload_symbol_decl): Remove function. (expand_omp_target): For BUILT_IN_GOMP_TARGET, BUILT_IN_GOMP_TARGET_DATA, BUILT_IN_GOMP_TARGET_UPDATE pass NULL instead of &__OFFLOAD_TABLE__, for BUILT_IN_GOACC_DATA_START, BUILT_IN_GOACC_ENTER_EXIT_DATA, BUILT_IN_GOACC_PARALLEL, BUILT_IN_GOACC_UPDATE don't pass it at all. libgomp/ * libgomp_g.h (GOACC_data_start, GOACC_enter_exit_data) (GOACC_parallel, GOACC_update): Remove const_void *offload_table formal parameter. Update all users. * target.c (GOMP_target, GOMP_target_data, GOMP_target_update): Document unused formal parameter. From-SVN: r219836
