------- Comment #3 from rguenth at gcc dot gnu dot org 2009-01-16 09:23 ------- I think you should simply do the check for an indirect base only if the folding of the view-convert-expr ended up in a view-convert-expr. Playing with alias-sets here will still cause these nested v-c-es with -fno-strict-aliasing and loads of unwanted (and likely unprofitable) v-c-es. Your testcase should be still optimized then.
