Not all C language features are supported when -mabi=ti option is used for PRU target. gcc/testsuite/ChangeLog: 2018-07-27 Dimitar Dimitrov <dimitar@dinux.eu> * lib/gcc-dg.exp: Filter unsupported features in PRU's TI ABI mode. * lib/target-utils.exp: Ditto. * lib/target-supports.exp (check_effective_target_function_pointers, check_effective_target_large_return_values): New.
