Duncan Sands	5a896a9858	Add test for improvement of readonly to readnone, ... and non-demotion of readnone to readonly. llvm-svn: 56344	2008-09-19 09:20:05 +00:00
Duncan Sands	af25ee7ffc	Add a new pass AddReadAttrs which works out which functions ... can get the readnone/readonly attributes, and gives them it. The plan is to remove markmodref (which did the same thing by querying GlobalsModRef) and delete the analogous functionality from GlobalsModRef. llvm-svn: 56341	2008-09-19 08:17:05 +00:00
