These forward declarations are a GNU extension, and they trigger
a build warning when the compiler does not support it.
gdb/ChangeLog:
* utils.h: #include "exceptions.h".
(enum errors): Remove partial declaration.
The current code attempts to provide relocation support when debugging
core files via the rs6000_xfer_partial method of the rs6000-nat
target_ops vector. However, this target_ops vector does not get pushed
on the target stack at all when debugging core files, thus bypassing
completely that part of the code.
This patch fixes the problem by extending corelow's core_xfer_partial
into handling the TARGET_OBJECT_LIBRARIES_AIX object.

Given the following code:
float global_float = 0.0;
void
set_float (float f)
{
global_float = f;
}
GDB incorrectly calls set_float if the set_float function is marked
as prototyped:
(gdb) call set_float (5.0)
(gdb) print global_float
$1 = 2048
What happens, when the function is marked as prototyped, is that
GDB finds that the argument is a float, casts the value given in
the expression to a float, and then gives that float to ppc-aix/
ppc-lynx178's push_dummy_call gdbarch routine. The latter then blindly
copies it as is in the first floating-point register, instead of
making sure that it has the proper format first.
gdb/ChangeLog:
* rs6000-aix-tdep.c (rs6000_push_dummy_call): Convert
floating point registers to register type before storing
value.
* rs6000-lynx178-tdep.c (rs6000_lynx178_push_dummy_call):
Likewise.
I saw some test cases in gdb.base/default.exp and gdb.base/setshow.exp
are enabling the history saving.
Hence .gdb_history file is modified with history information even
though, by default, we have History saving disabled.
So we should modify GDB test cases so that history saving should stay
off for all test cases.

(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.
gdb/

* 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.

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.

calculate the size of trace buffer. Use 'tfind pc func9'
instead of 'tfind 9'. Use 'with_test_prefix'.
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

Support" subsection documenting the XML format used to transfer

The test case gdb.arch/system-gcore.exp is almost an identical copy of
gdb.base/gcore.exp. The only functional change is the additional
comparison of the "info reg system" command output.
It should be safe to perform this comparison on all architectures.
Thus the patch removes the arch-specific version and adds "info reg
system" to the common gcore test case instead.
Tested on i686-linux and s390x-linux.
