Committed, along with new testcases vect-[62-69].c that were left out of the patch, and a fix to vect-13.c that caused a failure on ix86 (attached).

Have you done that? + #define VECT_SMODULO(x,y) ((x) % (y) < 0 ? ((x) % (y) + (y)) : (x) % (y)) This needs a comment. ! if (!evolution_function_is_constant_p (access_fn)) ! { ! if (!vect_is_simple_iv_evolution (loop_containing_stmt (DR_STMT (dr))->num, ! access_fn, &init, &step, true)) ! { ! if (vect_debug_details (NULL)) That should be: if (!e_f_i_c_p (access_fn) && !v_i_s_i_e (...) && vec_debug_details (NULL)) not three nested ifs. And vec_debug_details should probaby go at the outside since it will usually be false, avoiding computations implied by the other functions. Patch OK with those changes. -- Mark Mitchell CodeSourcery, LLC (916) 791-8304 mark@codesourcery.com
