* rtl.h (struct rtx_def): Add comment for field jump. (LRA_SUBREG_P): New macro. * recog.c (register_operand): Check LRA_SUBREG_P. * lra.c (lra): Add note at the end of RTL code. Align non-empty stack frame. * lra-spills.c (lra_spill): Align stack after spilling pseudos. (lra_final_code_change): Skip subreg change for operators. * lra-eliminations.c (eliminate_regs_in_insn): Make return earlier if there are no operand changes. * lra-constraints.c (curr_insn_set): New. (match_reload): Set LRA_SUBREG_P. (emit_spill_move): Ditto. (check_and_process_move): Use curr_insn_set. Process only single set insns. Don't initialize sec_mem_p and change_p. (simplify_operand_subreg): Use LRA_SUBREG_P. (reg_in_class_p): New function. (process_alt_operands): Use it. Use #if HAVE_ATTR_enabled instead of #ifdef. Add code to remove cycling. (process_address): Check EXTRA_CONSTRAINT_STR. Process even if non-null disp. Reload inner instead of disp when base and index are null. Try to put lo_sum into register. (EBB_PROBABILITY_CUTOFF): Redefine probability in percents. (check_and_process_move): Move code for move cost check to simple_move_p. Remove equiv_substitution. (simple_move_p): New function. (curr_insn_transform): Initialize sec_mem_p and change_p. Set up curr_insn_set. Call check_and_process_move only for single set insns. Use the new function. Move call of check_and_process_move after operand equiv substitution and address process. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@198344 138bc75d-0d04-0410-961f-82ee72b054a4
