Increase the accuracy of sparc instruction aliases.
Make current with UA2011 specification.
Add an F_PREFERRED opcode flag that indicates a preferred alias
when multiple aliases for the same opcode exists.
For 'lzd':
Add 'lzcnt' as primary instruction, and make 'lzd' an alias.
Add 'ldtw', 'ldtwa', 'sttw', 'sttwa':
The modern opcode for for 'ldd', 'ldda', 'std', and 'stda' on
integer registers. Mark the latter now as aliases.
For 'flush':
Support "[address]" syntax as well as plain "address".
Rework 'mov' aliases for 'wr':
Eliminate bogus three operand moves, and encode the
instructions properly for the "mov REG, %ASR" cases,
specifically we should encode the register in rs2 not rs1 as
per The SPARC V8 Architecture Manual.
Add missing cbcond aliases:
c{w,x}bz, c{w,x}blu, c{w,x}bnz, c{w,x}bgeu
Add 'd' suffix VIS logical ops:
The primary opcode for 'fzero' is now 'fzerod' (compare with
'fzeros'), for example. And thus 'fzero' is now an alias.
Add modern opcodes for condition code setting edge instructions:
They are now edgeN{,l}cc instead of plain edgeN{,l}.
Add modern opcodes for VIS comparisons:
All VIS comparisons now start with prefix "fp", retain the
older variants as aliases.
The signed variants for equal and not-equal have "u" aliases
to show that these comparisons are equally suited for unsigned
compares.
Update existing test cases as needed, and add several new ones.

A related issue is that the "commands" command actually supports
setting commands to a range of breakpoints/tracepoints at once. But,
hacking "maint info breakpoints" to print t->step_count, reveals:
(gdb) trace main
Tracepoint 5 at 0x45a2ab: file ../../src/gdb/gdb.c, line 29.
(gdb) trace main
Note: breakpoint 5 also set at pc 0x45a2ab.
Tracepoint 6 at 0x45a2ab: file ../../src/gdb/gdb.c, line 29.
(gdb) commands 5-6
Type commands for breakpoint(s) 5-6, one per line.
End with a line saying just "end".
> while-stepping 5
>end
> end
(gdb) maint info breakpoints 5
Num Type Disp Enb Address What
5 tracepoint keep y 0x000000000045a2ab in main at ../../src/gdb/gdb.c:29 inf 1
step_count=5
^^^^^^^^^^^^
while-stepping 5
end
not installed on target
(gdb) maint info breakpoints 6
Num Type Disp Enb Address What
6 tracepoint keep y 0x000000000045a2ab in main at ../../src/gdb/gdb.c:29 inf 1
step_count=0
^^^^^^^^^^^^
while-stepping 5
end
not installed on target
(gdb)
that tracepoint 6 doesn't end up with the correct step_count.
The issue is that here:
static void
do_map_commands_command (struct breakpoint *b, void *data)
{
struct commands_info *info = data;
if (info->cmd == NULL)
{
struct command_line *l;
if (info->control != NULL)
l = copy_command_lines (info->control->body_list[0]);
else
{
struct cleanup *old_chain;
char *str;
str = xstrprintf (_("Type commands for breakpoint(s) "
"%s, one per line."),
info->arg);
old_chain = make_cleanup (xfree, str);
l = read_command_lines (str,
info->from_tty, 1,
(is_tracepoint (b)
? check_tracepoint_command : 0),
b);
do_cleanups (old_chain);
}
info->cmd = alloc_counted_command_line (l);
}
validate_actionline is never called for tracepoints other than the
first (the copy_command_lines path). Right below, we have:
/* If a breakpoint was on the list more than once, we don't need to
do anything. */
if (b->commands != info->cmd)
{
validate_commands_for_breakpoint (b, info->cmd->commands);
incref_counted_command_line (info->cmd);
decref_counted_command_line (&b->commands);
b->commands = info->cmd;
observer_notify_breakpoint_modified (b);
}
And validate_commands_for_breakpoint looks like the right place to put
a call; if we reset step_count there too, we have a nice central fix
for the first issue as well, because trace_actions_command calls
breakpoint_set_commands that also calls
validate_commands_for_breakpoint.
We end up calling validate_actionline twice for the first tracepoint,
since read_command_lines calls it too, through
check_tracepoint_command, but that should be harmless.

I hacked "apropos" to dump the whole set of commands (just make it
accept the entry string as regex), and then diffed the output of 7.5
vs 7.6, --enable-targets=all builds. That allowed then checking
whether some commands had not been mentioned in NEWS or the manual.

unpush the remote target if serial_write fails.
PR gdb/15275 notes that when debugging with a remote connection over a
serial link and the link is disconnected, say by disconnecting USB
serial port, the GDB quit command no longer works:
(gdb)
tar ext /dev/ttyACM0
&"tar ext /dev/ttyACM0\n"
~"Remote debugging using /dev/ttyACM0\n"
^done
(gdb)
set debug remote 1
&"set debug remote 1\n"
^done
(gdb)
quit

quit
&"quit\n"
&"Sending packet: $qTStatus#49..."
&"putpkt: write failed: Input/output error.\n"
^error,msg="putpkt: write failed: Input/output error."
This is not reproducible with TCP connections, as with that, sending
doesn't error out, but instead the error is detected on the subsequent
readchar. When that read fails, we unpush the remote target, and
throw TARGET_CLOSE_ERROR. To address PR gdb/15275, instead of
catching the error in remote_get_trace_status as presently done (which
leaves this same issue latent for another packet to trip on), or of
making ser-unix.c fake success too on failed writes, so we'd get to
readchar detecting the error on serial ports too, better let the error
propagate out of serial_write, and catch it at the remote.c level,
throwing away the target if writing fails too, instead of delaying
that until the next read.

Stop sending qTStatus if the target doesn't recognize it; add packet configuration command.
GDB currently sends a qTStatus even if the target previously replied
an empty packet to a previous qTStatus. If the target doesn't
recognize the packet, there's no point in trying again.
The machinery we have in place is packet_ok, which has the nice side
effect of forcing one to install a configuration command/knob for the
packet in question, which is often handy when you need to debug
things, and/or emulate a target that doesn't support the packet, or even,
it can be used as workaround for the old broken kgdb's that return error

was applied, the "set listsize" command was a var_integer command, and
"unlimited" was set with 0. Internally, var_integer maps 0 to INT_MAX
case var_integer:
{
...
if (val == 0 && c->var_type == var_integer)
val = INT_MAX;
The change in that patch to zuinteger_unlimited command, meant that -1
is left as -1 in the command's control variable (lines_to_list), and
the code in source.c isn't expecting that -- it only expects positive
numbers.
I previously suggested fixing the code and keeping the new behavior,
but I found that "set listsize 0" is currently used in the wild, and
we do have a bunch of other commands where "0" means unlimited, so I'm
thinking that changing this command alone in isolation is not a good
idea.
So I now strongly prefer reverting back the behavior in 7.6 to the
same behavior the command has had since 2006 (0==unlimited, -1=error).
Before that, set listsize -1 would be accepted as unlimited as well.
After 7.6 is out, in mainline, we can get back to reconsidering
changing this command's behavior, if there's a real need for being
able to suppress output. For now, let's play it safe.
The "list line 1 with unlimited listsize" test in list.exp was
originally written years and years ago expecting 0 to mean "no
output", but GDB never actually worked that way, even when the tests
were written, so the tests had been xfailed then. This patch now
adjusts the test to the new behavior, so that the test actually
passes, and the xfail is removed.
