Description Teresa Thomas 2008-06-11 15:30:02 UTC 
(fhpd) print array      
{0,0,0,0}
(fhpd) print array[ 0:1] 
{0,0}
(fhpd) watch array[ 0:1]
Watchpoint set: array[ 0:1] (Uses 0 debug register(s))
Comment 1 Teresa Thomas 2008-06-11 18:56:33 UTC 
The watch installer was getting the size of the expression from the type parser.
But the type parser has no information on the size of a sliced array. Get size
from Location instead.

Commit:
    Fixes bug# 6623. Use Location.length() for getting expression size.

    	* WatchObserverInstaller.java (install): Use Location.length()
    	instead of Type.getSize().

Demo (IA32):

(fhpd) watch array[ 0:1]
(fhpd) Watchpoint set: array[ 0:1] (Uses 2 debug register(s))
