5572 with a false third argument.
5573 * tree-vect-generic.c (lower_vec_perm): Use can_vec_perm_const_p
5574 to test whether the constant selector is valid and can_vec_perm_var_p
5575 to test whether a variable selector is valid.

5607 * config/i386/x86-tune-costs.h: Increase cost of integer load costs

5614 * x86-tune-costs.h (generic_cost): Reduce cost of FDIV 20->17,
5615 cost of sqrt 20->14, DIVSS 18->13, DIVSD 32->17, SQRtSS 30->14
5616 and SQRTsD 58->18, cond_not_taken_branch_cost. 2->1. Increase

5623 TODO_cleanup_cfg if any changes have been made.
5626 * expr.c (store_expr_with_bounds): Use simplify_gen_subreg instead of
5627 convert_modes if target mode has the right side, but different mode
5631 * expr.c (expand_assignment): Fix up a typo in simplify_gen_subreg
5632 last argument when extracting from CONCAT. If either from_real or
5633 from_imag is NULL, use expansion through memory. If result is not
5634 a CONCAT and simplify_gen_subreg fails, try to simplify_gen_subreg
5635 the parts directly to inner mode, if even that fails, use expansion
5639 * expmed.c (expand_shift_1): For 2-byte rotates by BITS_PER_UNIT,
5640 check for bswap in mode rather than HImode and use that in expand_unop
