[RFC] "info powerpc"

[RFC] "info powerpc"

[Paul Gilliam]

The "Info powerpc" command has no subcommands and does nothing.

The testsuit tests "info powerpc altivec"

So, should I depreciate 'info powerpc', just get rid of it, or add the 'altivec' subcommand and just point it to 'info vector'?

Attached are three patches, each a different way to deal with this problem:

The first is 'easy_altivec.patch'.  It adds the "info powerpc altivec" sub-command and has it call the same
routine as "info vector" does.  The only down-side is that the routine 'vector_info' in infcmd.c has to be made global.

The second, 'altivec_alias.patch', functions like the first, except that infcmd.c is not touched.  Instead, an 'info powerpc altivec' command
is added that turns itself into an alias for "info vector" the first time it's called.  This can't be done with add_com_alias because the alias and 
the command being aliased are on different command chains.

The final patch, 'no_more_altivec.patch' depreciates the "info powerpc" command prefix and changes the testsuite to use "info vector".  To make
this work, 'lookup_cmd_composition' in cli/cli-decode.c had to be changed so that a prefix command that has no sub-commands
can be depreciated.

My personel favorite is the first one.  It does the right thing while leaving "info powerpc" useable for other sub-commands.  And it's simple.

My second favorite is the second one.  It's like the first, except only the rs6000-tdep.c file need be changed.  Well, maybe it's not so simple.

My least favorite is the third one.  While it's a clean fix to the problem, it slams the door on any future 'info powerpc' sub-commands.  It also
requires a fix so that prefix commands without any sub-commands can be depreciated.  Of course, we could just get rid of the "info powerpc"
command without depreciating it for a while first....

Let me know what you think.

Please accompany any changes to user-visible behavior (such as new
commands or changes in how existing command behave) with appropriate
changes to the user manual.  Thanks.

The "info powerpc" group of commands (all none of them) are not documented.

If we decide to just get rid of it, then no user manual changes are needed.

If we decide to keep it and make 'info powerpc altivec' an alias for "info vector", then we can use the attached doc patch.

As you point out, "info powerpc" was until now a prefix with no
commands, that's why it is undocumented (or, rather, all zero of these
commands are documented ;-).

> If we decide to just get rid of it, then no user manual changes are needed.

Right; but your favorite alternative was to keep it.

I don't think this is a good place for this section.  There's already
a section on PowerPC-specific features, so we should add this
information there, I think.

I think this text should have a cross-reference to the "Vector Unit"
node, since the new command essentially does the same job, right?

Finally, we need a ChangeLog entry for this change.

Other than that, this patch for the manual is approved, assuming that
the code patches are also approved.  Thanks.

To be honest, from a multi-platform viewpoint, my favourite would be
to get rid of "info powerpc" completely.  But given the fact that we
let the "info powerpc altivec" test slip into the testsuite, and you
seem to like that command, I have no objection to make vector_info()
non-static; your second patch seems too much of a kludge.

Please try to get Andrew's or Kevin's approval though

If you just remove it, you don't slam the door on anything.  We can add
it back the moment we've got a use for it.

We have a common routine for printing vector registers; I would prefer
using "info vector" instead of extending "info powerpc".

How on earth did these tests get added to the FSF sources without the
command they're testing?  Ah-hah, they didn't.  This is why repository
history and ChangeLogs are so useful.

Ok, I agree.

Door 3 it is:  Do I need anymore more approvals to commit?

Well, I think it is silly to deprecate a command *prefix* (of course
it was silly to have that command prefix in the first place).  So I'd
propose simply removing that code instead of adding code to
cli/cli-decode.c to allow such a silly deprecated empty prefix.

If I'm not mistaken, Daniel suggested just removing the "info powerpc"
command.  Your no_more_altivec.patch does a bit more than this in that
it deprecates this command as well.

I'm comfortable with a patch that removes the "info powerpc" command
and updates the testsuite to use "info vector".  Consider such a patch
as preapproved.  (But do post it to the list after committing it.)

Thanks!

[commit] "get rid of info powerpc"

[Paul Gilliam]

[-- Attachment #1: Type: text/plain, Size: 1098 bytes --]

Attached is the patch I committed.  It just gets rid of the 'info powerpc' command prefix and patches the test
to use 'info vector' instead.

One question though:  I made an entry in the src/gdb/ChangeLog for the change to src/rs6000-tdep.c and one
in the src/gdb/testsuite/ChangeLog for for the change to altivec-regs.exp.  Was that the right way to do it?
Should I just have made one ChangeLog entry in src/gdb/ChangeLog?

No, that's correct.

I noticed that you didn't update the copyright dates for the Altivec
tests when you started changing them earlier this year, so I've also
committed the attached.
