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. From-SVN: r198344 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
