opts.c (decode_options): Do not handle flag_strength_reduce.
* opts.c (decode_options): Do not handle flag_strength_reduce.
(common_handle_option): Handle OPT_floop_optimize, OPT_frerun_loop_opt
and OPT_fstrength_reduce.
* tree-ssa-loop.c (tree_ssa_loop_prefetch): Only test
flag_prefetch_loop_arrays for being nonzero.
* common.opt (floop-optimize, frerun-loop-opt): Resurrected as
no-ops.
(fprefetch-loop-arrays-rtl): Removed.
(flag_prefetch_loop_arrays): Do not specify the value.
* doc/passes.texi: Update documentation of loop optimizer
passes.
* doc/invoke.texi (-fstrength-reduce, -fprefetch-loop-arrays-rtl,
-frerun-loop-opt): Remove.
* gcc.target/i386/20000614-2.c: Do not use -fno-strength-reduce.
* gcc.dg/20030324-1.c: Do not use -fstrength-reduce.
