create_breapoint / explicit mode: Error out if there's garbage after the breakpoint location.
If !PARSE_CONDITION_AND_THREAD, then ARG is just the location, nothing
else. The fact that the describing comment of create_breakpoint
doesn't mention this just looks like an oversight of when extra_string
was added. "parse_condition_and_thread" has been a misnomer ever
since extra_string was added -- better rename it avoid more confusion.
This makes it "parse_arg", as that'll remain stable even if/when more

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.
* sparc-dis.c (compare_opcodes): When encountering multiple aliases

as aliases. Add "fp" prefix to VIS compare instructions, mark

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

(gdb) maint info breakpoints 6

step_count=0
^^^^^^^^^^^^
while-stepping 5
end
not installed on target
(gdb)
that tracepoint 6 doesn't end up with the correct step_count.
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

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:
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.
