* Enable prefetching at -O3 for AMD cpus.spop2010-06-251-1/+1
| | | | | | | | | | | | | | | | | | 2010-06-25 Changpeng Fang <changpeng.fang@amd.com> * common.opt (fprefetch-loop-arrays): Re-define -fprefetch-loop-arrays as a tri-state option with the initial value of -1. * tree-ssa-loop.c (gate_tree_ssa_loop_prefetch): Invoke prefetch pass only when flag_prefetch_loop_arrays > 0. * toplev.c (process_options): Note that, with tri-states, flag_prefetch_loop_arrays>0 means prefetching is enabled. * config/i386/i386.c (override_options): Enable prefetching at -O3 for a set of CPUs that sw prefetching is helpful. (software_prefetching_beneficial_p): New. Return TRUE if software prefetching is beneficial for the given CPU. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@161391 138bc75d-0d04-0410-961f-82ee72b054a4
