--- Comment #22 from Jan Hubicka <hubicka at gcc dot gnu.org> 2010-12-19 11:53:32 UTC --- freq: 8000 size: 2 time: 2 D.13088_5480 = VIEW_CONVERT_EXPR<vector int>(D.8004_729); freq: 8000 size: 2 time: 2 D.13087_5481 = VIEW_CONVERT_EXPR<vector int>(a_5271); freq: 8000 size: 7 time: 16 D.13086_5482 = __builtin_ia32_paddd128 (D.13087_5481, D.13088_5480); obviously we also should count V_C_E as free like other conversions. Will test patch for that.
