* loop.h (express_from): Declare. (struct induction): Replace derived flag with derived_from pointer. * loop.c (strength_reduce, record_giv, recombine_givs): Likewise. (express_from): No longer static. * unroll.c (find_splittable_givs): Replace derived with derived_from. When processing an address giv with which another giv has been combined that has also been derived from a third giv, handle like having combined with the third giv. Set splittable_regs_updates appropriately for derived givs. From-SVN: r25007
