No.  But there is a reason.

The existing h/w breakpoint macros should be moved to the target vector 
and not the architecture vector.  This is because the target, and not 
the architecture, determines the presence of a breakpoint mechanism.

Unfortunatly, so far, no one has made this change, sigh!

Interested?

e.g., a sim target might support h/w breakpoints when the architecture 
doesn't have the, a native target may not support h/w breakpoints even 
when the architecture does have them.
