Subj : Question on js_LookupPropertyWithFlags

I feel confused about the flag of JSCLASS_NEW_RESOLVE_GETS_START.
In file "jspubtd.h", there is a comment for JSNewResolveOp which is:
"Setting JSCLASS_NEW_RESOLVE and JSCLASS_NEW_RESOLVE_GETS_START further
extends this hook by passing in the starting object on the prototype
chain via *objp." So when there is a call to lookupproperty and the
flag of JSCLASS_NEW_RESOLVE_GETS_START has been set, the lookup
operation should start from *objp. But when I turned to the function
js_LookupPropertyWithFlags in "jsobj.c", it seems that the parameter
*objp isn't used for that purpose.
Maybe I don't fully understand the code. Or maybe you can give me some
help.

Thanks.

Alfred
