------- Comment #2 from rguenth at gcc dot gnu dot org 2010-04-20 12:56 ------- Well. early inlining is then just lucky in 4.3 - the functions are really too big for early inlining to inline fully. Btw, IPA inlining does inline operator= into start_thread. In 4.3 we do not inline a destructor which is why the 4.5 code is bigger.
