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.
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.)

(One of the new comments mentions breakpoint always-inserted mode.
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.)

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.
This patch makes the tests handle this scenario.

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.
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.)

"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.
