Subject: [PATCH 3/4] Expand watchpoint lengths to LONGEST

--MP_/6HRlH6vpyqtSy4CYyMrX6b2

Content-Type: text/plain; charset=US-ASCII

Content-Transfer-Encoding: 7bit

Content-Disposition: inline

Hi,

This is part three of the bitpos expansion change.  Some architectures

allow arbitrary length watchpoints and combined with the fact that type

lengths could be large enough, we need LONGEST for watchpoint lengths.

It is architecture dependent however, whether the LONGEST is needed or

not.  This patch updates the signatures of watchpoint insertion and

removal functions of all architectures (to comply with the function

signatures in the callback struct), but expands types only in

architectures that need it.  Tested on Fedora 16 x86_64.

Regards,

Siddhesh
