But the dprintf tests still fail with some GDBserver targets because they doesn't try to handle the case of the server reporting support for breakpoint commands, but not be able to use those in combination with Z0 (because Z0 isn't actually supported, for example): FAIL: gdb.base/dprintf.exp: 1st dprintf, agent FAIL: gdb.base/dprintf.exp: 2nd dprintf, agent FAIL: gdb.base/dprintf.exp: dprintf info 2 (pattern 4) Similarly for the MI test. This patch makes the tests handle this scenario. Tested with native, and native gdbserver on x86_64 Fedora 17. Also tested with the native-gdbserver.exp board hacked with: set GDBFLAGS "${GDBFLAGS} -ex \"set remote breakpoint-commands off\"" (actually, "set remote breakpoint-commands off" is presently broken, so this was on top of a fix for that command.) which results in: (gdb) PASS: gdb.base/dprintf.exp: 2nd dprintf, gdb set dprintf-style agent warning: Target cannot run dprintf commands, falling back to GDB printf warning: Target cannot run dprintf commands, falling back to GDB printf (gdb) UNSUPPORTED: gdb.base/dprintf.exp: set dprintf style to agent gdb.sum: Running target native-gdbserver Running ../../../src/gdb/testsuite/gdb.base/dprintf.exp ...

Actually testing with breakpoint always-inserted mode fails these dprintf tests, due to the way they are written. But that'll take a more substancial rewrite of the tests, so I'm leaving that for another day.) gdb/testsuite/ 2014-03-24 Hui Zhu Pedro Alves PR breakpoints/16101 * gdb.base/dprintf.exp: Use unsupported rather than changing the test pass/fail messages.
