* expr.c (convert_move): When a partial_int requires multiple
conversion steps, make sure successive steps convert the intermediate value, not the original value. * expmed.c (expand_mult): Convert partial_int multiplies to shift/add combinations too. * genmodes.c (mode_data): Add wider_2x. (calc_wider_mode): Calculate twice-wider mode too. (emit_mode_wider): Emit twice-wider mode too. * machmode.h (mode_2xwider, GET_MODE_2XWIDER_MODE): New. * expr.c (expand_expr_real_1): Use it for expanding multiplies. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@100414 138bc75d-0d04-0410-961f-82ee72b054a4
