gdb_test_no_output "set dprintf-style call" "set dprintf style to call"
Fix PR breakpoints/16101: gdb.base/dprintf.exp agent-printf failures with non-Z0-supporting gdbservers After a previous patch that was committed by Pedro (0000e5cc), trying to set a dprintf with with a GDBserver that doesn't support agent commands at all now throws an error. 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.

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.

gdb_test "set dprintf-style foobar" "Undefined item: \"foobar\"." \
"Set dprintf style to an unrecognized type"
Fix several "set remote foo-packet on/off" commands. For several RSP packets, there's a corresponding "set remote foo-packet on/off/auto" command that one can use do bypass auto-detection of support for the packet or feature. However, I noticed that setting several of these commands to 'on' or 'off' doesn't actually have any effect. These are, at least: set remote breakpoint-commands-packet set remote conditional-breakpoints-packet set remote fast-tracepoints-packet set remote static-tracepoints-packet set remote install-in-trace-packet These are commands that control a remote protocol feature that doesn't have a corresponding regular packet, and because of that we cache the knowledge of the remote side support as returned by the qSupported packet in the remote_state object. E.g., in the case of the 'set remote breakpoint-commands-packet' command, whether the feature is supported is recorded in the 'breakpoint_commands' field of the remote_state object. Whether to bypass packet support auto-detection or not is controlled by the 'detect' field of the corresponding packet's packet_config structure. That field is the variable associated directly with the "set remote foo-packet" command. Actual remote stub support for the packet (or feature) is recorded in the 'support' field of the same structure. However, when the user toggles the command, the 'support' field is also correspondingly updated to PACKET_ENABLE/DISABLE/SUPPORT_UNKNOWN, discarding the knowledge of whether the target actually supports the feature. If one toggles back to 'auto', it's no big issue for real packets, as they'll just end up re-probed the next time they might be necessary. But features whose support is only reported through qSupported don't get their corresponding (manually added/maintained) fields in remote_state objected updated. As we lost the actual status of the target support for the feature, GDB would need to probe the qSupported features again, which GDB doesn't do. But we can avoid that extra traffic, and clean things up, IMO. Instead of going in that direction, this patch completely decouples struct packet_config's 'detect' and 'support' fields. E.g., when the user does "set remote foo-packet off", instead of setting the packet config's 'support' field to PACKET_DISABLE, the 'support' field is not touched at all anymore. That is, we end up respecting this simple table: | packet_config->detect | packet_config->support | should use packet/feature? | |-----------------------+------------------------+----------------------------| | auto | PACKET_ENABLE | PACKET_ENABLE | | auto | PACKET_DISABLE | PACKET_DISABLE | | auto | PACKET_UNKNOWN | PACKET_UNKNOWN | | yes | don't care | PACKET_ENABLE | | no | don't care | PACKET_DISABLE | This is implemented by the new packet_support function. With that, we need to update this pattern throughout: if (remote_protocol_packets[PACKET_foo].support == PACKET_DISABLE) to do this instead: if (packet_support (PACKET_qAttached) == PACKET_DISABLE) where as mentioned, the packet_support function takes struct packet_config's 'detect' field into account, like in the table above. As when the packet is force-disabled or force-enabled, the 'support' field is just ignored, if the command is set back to auto, we'll resume respecting whatever the target said it supports. IOW, the end result is that the 'support' field always represents whether the target actually supports the packet or not. After all that, the manually maintained breakpoint_commands and equivalent fields of struct remote_state can then be eliminated, with references replaced by checking the result of calling the packet_support function on the corresponding packet or feature. This required adding new PACKET_foo enum values for several features that didn't have it yet. (The patch does not add corresponding "set remote foo-packet" style commands though, focusing only on bug fixing and laying the groundwork). Tested on x86_64 Fedora 17, native GDBserver. The new tests all fail without this patch. gdb/ 2014-04-25 Pedro Alves <palves@redhat.com> * remote.c (struct remote_state): Remove multi_process_aware, non_stop_aware, cond_tracepoints, cond_breakpoints, breakpoint_commands, fast_tracepoints, static_tracepoints, install_in_trace, disconnected_tracing, enable_disable_tracepoints, string_tracing, and augmented_libraries_svr4_read fields.
