* regstat.c (regstat_bb_compute_ri): Compute FREQ_CALLS_CROSSED. * cfg.c (dump_reg_info): Print it. * regs.h (struct reg_info_t): add freq_calls_crossed. (REG_FREQ_CALLS_CROSSED): New macro. * global.c (global_alloc): Compute freq_calls_crossed for allocno. (find_reg): Update call of CALLER_SAVE_PROFITABLE. * regmove.c (optimize_reg_copy_1, optimize_reg_copy_2, fixup_match_2, regmove_optimize): Update call crossed frequencies. * local-alloc.c (struct qty): Add freq_calls_crossed. (alloc_qty): Copute freq_calls_crossed. (update_equiv_regs, combine_regs): Update REG_FREQ_CALLS_CROSSED. (find_free_reg): Update call of CALLER_SAVE_PROFITABLE. * ra.h (struct allocno): Add freq_calls_crossed. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@131576 138bc75d-0d04-0410-961f-82ee72b054a4
