Make tests expect [ \t]+ pattern instead of \t for "info reg" command
Commit Message
This will allow to format output of "info reg" command as we wish,
without breaking the tests. In particular, it'll let us correctly align
raw and natural values of the registers using spaces instead of current
badly-working approach with tabs.
This change is forwards- and backwards-compatible, so that the amended
tests will work in the same way before and after reformatting patches
(unless the tests check formatting, of course, but I've not come across
any such tests).
Some tests already used this expected pattern, so they didn't
even have to be modified. Others are changed by this patch.
I've checked this on a i386 system, with no noticeable differences in
test results, so at least on i386 nothing seems to be broken by this.
gdb/testsuite/ChangeLog:
* gdb.arch/powerpc-d128-regs.exp: Replace expected "\[\t\]*" from
"info reg" with "\[ \t\]*".
* gdb.arch/altivec-regs.exp: Replace expected "\t" from "info reg" with
"\[ \t\]+".
* gdb.arch/s390-multiarch.exp: Ditto.

No objection on my end. I might have used \\s instead of \[ \t\],
but perhaps there was a reason not to; and even if not, no point
in redoing it all now.
Anyone against this change?

This change looks like it's doing more than just allowing spaces
on top of tabs...
For the rest of this (large and mechanical patch), I tried my best
to pay attention to all the details.

\\s would also allow newlines, form feeds etc., which doesn't look
like a good idea here.

Well it allows _multiple_ spaces/tabs instead of exactly one tab —
exactly what we need to be compatible with space-alignment. In other
respects I don't see what else it does.

Hmmm, true. Forgot about newlines in particular.

My mistake. I was seeing 2 new lines, because one of the '+' lined up
exactly at the start of the next line when wraparound gets involved.
Upon re-examination, the change looks fine indeed.

Why alignment with tabs is "badly-working"? Do you have some other
patches to change the output of "info reg"?

For your questions of "what format" and "why current is bad" please
see my previously sent (but not applied) patch:
https://sourceware.org/ml/gdb-patches/2017-07/msg00046.html
(and its follow-up version 2:
https://sourceware.org/ml/gdb-patches/2017-07/msg00406.html ).
In short, "info reg" prints three columns, and the third one is
aligned by a single tab. This works well only in two cases: all
registers have short hex values (i.e. less than 8 chars wide), or all
have long values. Then the tab shifts the third column of values to
the same terminal character column.
Initially (in the patch linked above) I wanted to preserve the tab and
only pad it with subsequent spaces to a fixed column, thus avoiding
breaking the tests, but after the discussion I understood that it's
too hacky to be a solution, and it's better to fix the tests and then
use space-only alignment, similarly to what is done with the second
column.
As for "some other patches", I don't have any particular change in
mind currently.

Thanks for bringing more context, which is helpful to understand
the patch. It is good to me, you can push.
