rtl.h (struct rtx_def): Add comment for field jump.
2013-04-26 Vladimir Makarov <vmakarov@redhat.com>
* 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.
