uwe	f482b86d5d	gcc4 generated extremely unoptimal code for shifts of 64-bit ints on SuperH. ... Pull over a fix from gcc 4.1 branch. ok mrg@ Author: sayle Date: Fri Jul 21 13:22:31 2006 New Revision: 115644 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=115644 Log: PR middle-end/28283 * expmed.c (expand_shift): Additionally check that the shift_cost is not MAX_COST and that INTVAL(op1) is less than MAX_BITS_PER_WORD before implementing a LSHIFT_EXPR as a sequence of additions. * config/sh/sh.c (shift_costs): Return MAX_COST to inform the middle-end that DImode shifts need to be synthesized by expand.
