Re: [PATCH] Print vector registers in natural format, not hex

Thanks, this is approved.

Do we have facilities for printing vector registers?  If so, we should
probably add a cross-reference to their description here.  The
intersted reader will most probably wonder what can she do to print
vector registers when she reads these passages.
The closest facility is the 'info vector' command, which by default prints the contents of all vector registers, but is documented simply as "Print the status of the vector unit.", which I take to mean that it can be overridden to have arch-specific output, much like 'info float'. An 'info vector-registers' and 'info fp-registers' command might not be such a bad idea, but none exists at the moment that I know of.

We'll also probably need to look at the following chunk of documentation if/when this patch is accepted:

@value{GDBN} always considers the contents of an ordinary register as an
integer when the register is examined in this way. Some machines have
special registers which can hold nothing but floating point; these
registers are considered to have floating point values. There is no way
to refer to the contents of an ordinary register as floating point value
(although you can @emph{print} it as a floating point value with
@samp{print/f $@var{regname}}).
Maybe something along the lines of:

@value{GDBN} always considers the contents of an ordinary register as an
integer when the register is examined in this way. Some machines have
special registers that are predefined to have specific types (typically floating
point or vector registers); these registers are printed according to their
system-defined type. There is no way to refer to the contents of an ordinary
register as a floating point value or vector type (although you can @emph{print}
it as a floating point value with @samp{print/f $@var{regname}}).
