(gdb) show remote traceframe-info-packet
Support for the `qXfer:trace-frame-info:read' packet is auto-detected, currently unknown.
^^^^^^^^^^^
The packet is actually qXfer:traceframe-info:read.

* remote.c (_initialize_remote): Fix spelling of
qXfer:traceframe-info:read packet in packet config command.
In the function remote_trace_set_readonly_regions in gdb/remote.c, the
local variable 'offset' does not account for "QTro" at the start of
the packet with the result that if there are any read-only regions,
the packet is sent -- but without the "QTro" -- causing the remote
stub to report that the packet is unsupported:
Sending packet: $:0000000000400200,(...),00000000004560a4#ab...Packet received:
vs the expected:
Sending packet: $QTro:0000000000400200,(...),00000000004560a4#31...Packet received: OK
We don't see the problem when testing with GDBserver, as that supports
qXfer:trace-frame-info:read, meaning GDBserver never needs to read
from the read-only sections directly itself. This commit adds a test
that explicitly disables qXfer:trace-frame-info:read.

This issue should now be fixed thanks to a change in bfd removing
the SEC_ALLOC flag from all sections that do not get mapped to
memory.

Remove FIXME comment.
The routines in sparc-sol-thread used to be SPARC-specific (and
documented as such in the ptrace man page), and therefore hosting them
in a sparc-specific file made sense. However, newer versions of
Solaris now use those callbacks (Solaris 10 Update 10, apparently),
and thus the note about these callbacks being specific to SPARC
was removed.
So this patch deletes sparc-sol-thread.c and moves the code back
inside sol-thread.c.

This is a minor cleanup that helps avoiding duplicating the output
of a command when handling alternative situations.
gdb/ChangeLog:
* sol-thread.c (info_cb): Factorize the code a little.
This patch does the following:
- Puts the startfunc and "Sleep func" info on the same line;
- Renames "Sleep func" into "sleepfunc" to be consistent with
"startfunc"
- Avoids the use of a '-' as a separate before the "sleepfunc"
output, because the '-' looks odd and out of place when the
"startfunc" field is not printed (ti.ti_startfunc is nul).
- Use a '=' instead of ':' and avoids the space between
the name of the value and its value, mostly to help group
the value with its name.
For the record, this is how the new outout now looks like:
(gdb) maintenance info sol-threads
user thread #1, lwp 1, (active)
system thread #2, lwp 2, (active)
system thread #3, lwp 0, (asleep) sleepfunc=0xff32d9e0

This patch avoids a warning when resuming the execution of a program
that we attached to. For instance:
(gdb) attach 29989
(gdb) continue
Continuing.
warning: Mach error at "/[...]/darwin-nat.c:738" in function
"darwin_resume_thread": (os/kern) failure (0x5)
The warning is relatively harmless, but worrisome for the average
user. The warning comes from the fact that darwin_wait recorded
that the fake stop event corresponding to the suspend action was
caused by the main thread being suspended on a SIGTRAP. As a result
of this, when resuming the program's execution, we try to resume
the thread's execution as well. This is where the issue occurs,
as the thread was not in fact suspended, thus triggering the warning.
