Subject: Finally ... type mungers now remember where they came from in their attributes. ... 
X-Git-Tag: Root_AspectJ5_Development~194
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=cf858230583bd35bc49534c894930bd547682965;p=aspectj.git

Finally ... type mungers now remember where they came from in their attributes.  So during binary weaving we can determine the source of the declarations.  We will still understand the old form of attribute that is missing the source location.
(This means incremental compilation of ITDs will work properly for the IDE.)
