In my remote cross testing (x86_64 host and aarch64 target), the test gdb.base/sizeof.exp is skipped because gdb,noinferiorio is defined in my gdbserver board file. Tests are skipped because the test checks the expected value from the program's output, but I don't see why must do it this way. With my patch applied, we can save the result in variable in the program, and check the variable then. Then, the test doesn't rely on inferiorio. gdb/testsuite: 2015-12-03 Yao Qi <yao.qi@linaro.org> * gdb.base/sizeof.c: Don't include stdio.h and ../lib/unbuffer_output.c. (main): New variable 'size' and 'value'. Remove printf and gdb_unbuffer_output. Assign return value to size and value. * gdb.base/sizeof.exp: Remove the checking to gdb,noinferiorio at the beginning. (check_sizeof): Check the result by printing variable 'size'. (check_valueof): Check the result by printing variable 'value'.
