Add a new modifier /c to "disassemble" command to make it output binary code

Add a new modifier /c to "disassemble" command to make it output binary code

[Hui Zhu]

[-- Attachment #1: Type: text/plain, Size: 10117 bytes --]

Hi,

The objdump will output the binary code when it works but gdb not.
I make a patch to add a new modifier /c to "disassemble" command to
make it output binary code.
Please help me review it.

Thanks,
Hui

2009-07-09  Hui Zhu  <teawater@gmail.com>

	* cli/cli-cmds.c (disassemble_command): Add a new modifier /c
	to "disassemble" command to make it output binary code.
	(init_cli_cmds): Ditto.
	(print_disassembly): Add a new argument "code" to make sure
	output binary code or not.
	(disassemble_current_function): Ditto.
	* mi/mi-cmd-disas.c (mi_cmd_disassemble): Ditto.
	* stack.c (gdb_disassembly_stub): Ditto.
	* disasm.h (gdb_disassembly): Ditto.
	* disasm.c (do_mixed_source_and_assembly): Ditto.
	(do_mixed_source_and_assembly): Ditto.
	(do_assembly_only): Ditto.
	(gdb_disassembly): Ditto.
	(dump_insns): Output the binary code if "code" is true.

I think this patch looks good.

I'm slightly more of a fan of the "flags" approach, so that we can
easily add more flags later if we want.  But it isn't a big deal.

>> +With a /c modifier, binary code are included.\n\

I think this would be better as:

With a /c modifier, print the instruction in hex as well as
in symbolic form.

(This is what the objdump documentation says, and I think it is
clearer, by virtue of being more explicit.)

>> +              ui_out_message (uiout, 0, " %02x", (unsigned)data);

I wasn't sure about ui_out_message, and reading the internals docs was
not really enlightening on the subject.  I guess it is probably ok,
but if somebody else knows for sure, I'd like to be better informed.

I think this also needs a change to NEWS.  We mention disassemble/m
there, we ought to mention /c as well.

Please fix the help text; and after a doc review, if nobody has
responded about the ui_out_message thing, I will approve this.

Yes, definitely.

[Hui Zhu]

[-- Attachment #1: Type: text/plain, Size: 12655 bytes --]

Thanks everybody,

1. I added a argument "flags".  It include "DISASSEMBLY_SOURCE" and
"DISASSEMBLY_RAW_INSN".
2. I change the introduce to "With a /r modifier, print the
instruction in hex as well as in symbolic form."  It get from
objdump's man.  Wish you like it.  :)
3. /c changed /r.
4. I have make a patch for testsuite.

Please help me review them.

Thanks,
Hui

 With a /r modifier, raw instructions in hex are included.

(Use "raw" explicitly to help people remember why there's an `r' in
"/r".)

 and print the raw instructions in hex as well as in symbolic form

Again, please use the word "raw" in the text.

Also, what about NEWS? didn't we agree that an entry there would be a
Good Thing?

This is caused by this part of Hui's patch:

--- a/mi/mi-cmd-disas.c
+++ b/mi/mi-cmd-disas.c
@@ -156,6 +156,6 @@ mi_cmd_disassemble (char *command, char

   gdb_disassembly (gdbarch, uiout,
   		   file_string,
-		   mixed_source_and_assembly, how_many, low, high);
+		   DISASSEMBLY_SOURCE, how_many, low, high);

 }

Note how the new code completely ignores the mixed_source_and_assembly
flag (which is set from the mixed_mode MI parameter).

The following patch fixes this.
Tested on powerpc64-linux, committed to mainline.

Re: Add a new modifier /c to "disassemble" command to make it output binary code

I think you mean "hex dump of machine code", not "binary code".  In
any case, "binary code is included", in singular, not plural.

> -@itemx disassemble /m
> +@itemx disassemble /mc

Isn't it better to show that the modifiers are independent?  Like
this:

 @item disassemble
 @itemx disassemble /m
 @itemx disassemble /c


> -the @code{/m} modifier.

Again, I think "machine code in hex dump format" is better.

Okay with these changes.

Re: Add a new modifier /c to "disassemble" command to make it output binary code

[Michael Snyder]

How about test suites?
At a minimum, gdb.base/help.exp probably needs an update.

Re: Add a new modifier /c to "disassemble" command to make it output binary code

I like the idea.
The option to objdump is --[no-]show-raw-insn.
The word "raw" is the mnemonic I use to remember the option name.
Hence I wonder if it would be easier for users to remember
"disassemble /r" than "disassemble /c".

Yes, and perhaps have "show raw instructions" somewhere in the text of
the manual that describes this.

Actually I think you have a point here.  The term "code" is horribly
overloaded, so I felt a bit uncomfortable with the fact that the newly
added argument to print_disassembly carried that name:

>>  static void
>>  print_disassembly (struct gdbarch *gdbarch, const char *name,
>> -		   CORE_ADDR low, CORE_ADDR high, int mixed)
>> +		   CORE_ADDR low, CORE_ADDR high, int mixed, int code)

If people agree with Doug and me that /r is better than /c, can the
code be changed to match this?
