There are also some duplication on getting HW watchpoint/breakpoint
registers info between GDB and GDBserver. This patch moves them
to nat/aarch64-linux-hw-point.c.
Note that ENABLE_NLS is not defined in GDBserver, so it should be OK

Since multi_line was moved to gdb.exp in a slightly stricter form,
The gdb.ada/info_exc.exp:info exceptions test has been failing.
This is because it now expects a new-line sequence at the end of
each argument given to multi_line, including ".*". But the intent
when writing the test was to signify "could-be-nothing-at-all".
As a result, the test fails on x86_64-linux with a runtime built as
recommended, because of that
extra new-line sequence.

When I look at test fails related to watchpoint on aarch64-linux,
I find there are some code duplicates between GDB and GDBserver.
This patch is to move some of them to a nat/aarch64-linux-hw-point.{h,c}.
The only change I do is about the dr_changed_t typedef, which was
ULONGEST in GDB and 'unsigned long long' in GDBserver. Each bit
of dr_changed_t represents a status of each HW breakpoint or
watchpoint register, and the max number of HW breakpoint or watchpoint
registers is 16, so the width of 'unsigned long long' is sufficient.

Some functions on handling HW watchpoint in GDB and GDBserver looks the
same except the code getting debug register state from current inferior.
In GDB, we get debug register state like this:
state = aarch64_get_debug_reg_state (ptid_get_pid (inferior_ptid));
while in GDBserver, we get debug register state like this:
state = aarch64_get_debug_reg_state ();
This patch is to move two lines above out of some functions, and pass
aarch64_debug_reg_state to these functions, in this way, these functions
are the same, and can be moved to a common place.

target_post_startup_inferior (pid_to_ptid (pid));

(gdb) FAIL: gdb.arch/i386-biarch-core.exp: core-file
There are two problems:
(1) The testcase did not really test if elf64-i386 is supported by GDB (BFD).
That was OK for a Fedora testcase but I forgot about it when submitting it
upstream.
I haven't really verified if the GNU target is elf64-little but it seems so,
no other one seems suitable from:
elf32-x86-64
elf64-big
elf64-k1om
elf64-l1om
elf64-little
elf64-x86-64
pei-x86-64
(2) The output of the "core-file" command itself can be arbitrary as the
elf64-i386 file with x86_64 registers is really broken; but that does not
matter much, important is the following test whether core file memory is
readable.
./configure --enable-64-bit-bfd

I do not know much dejagnu but I expect 'istarget' tests against the site.exp
'target_triplet' content which is set to the primary GDB target
(--target=...).
GDB is normally never configured for primary target elf64-i386, I think BFD
does not know such explicit target, it gets recognized as elf64-little.
In fact many testfiles of the GDB testsuite are wrong as they require
'istarget' (therefore primary GDB target) even for just loading arch specific
files which would be sufficient with secondary target (--enable-targets=...)
support.
This my new patch removes this 'istarget' check as it is IMO unrelated to what
we need to test. Although you are right we do 'x/i' and test for 'hlt' so
I think we should test also for available 'set architecture i386'.
We could also test by 'x/bx' instead of 'x/i' to avoid such additional
test/requirement.
This testcase comes from a different bug from 2009:
https://bugzilla.redhat.com/show_bug.cgi?id=457187http://pkgs.fedoraproject.org/cgit/gdb.git/commit/?id=94cd124608bf0dd359cb48a710800d72c21b30c3
That bug has been fixed in the meantime but the same testcase was reproducing
this new different bug - internal error regression - so I submitted it.
We can remove the "x/bx $address" test but it was useful for the previous bug
from 2009 as that time the internal error regression did not happen, just the
core file was not recognized (which would not be detected by the proposed
ignoring of the "core-file" command output) and so the core file was not
available. That can be tested by the "x/bx $address" test.

I noticed two failure in gdb.trace/mi-trace-frame-collected.exp:
FAIL: gdb.trace/mi-trace-frame-collected.exp: live:
-trace-frame-collected (register)
FAIL: gdb.trace/mi-trace-frame-collected.exp: tfile:

In these cases, we are not collecting registers so the MI command
-trace-frame-collected should only give us the value of the PC.
However, it also gives us all of the single precision pseudo registers,
initialized with 0x0.
We can reproduce this error by simply issuing the
'maint print cooked-register' when no inferior is connected:
