bt-load.c: New file.
2003-06-18 Stephen Clarke <stephen.clarke@superh.com> J"orn Rennecke <joern.rennecke@superh.com> * bt-load.c: New file. * Makefile.in (OBJS): Include bt-load.o (bt-load.o): Add dependencies. * flags.h (flag_branch_target_load_optimize): Declare. (flag_branch_target_load_optimize2): Likewise. * hooks.c (hook_reg_class_void_no_regs): New function. (hook_bool_bool_false): Likewise. * hooks.h (hook_reg_class_void_no_regs, hook_bool_bool_false): Declare. * rtl.h (branch_target_load_optimize): Declare. * target-def.h (TARGET_BRANCH_TARGET_REGISTER_CLASS): Define. (TARGET_BRANCH_TARGET_REGISTER_CALLEE_SAVED): Likewise. (TARGET_INITIALIZER): Include these. * target.h (struct gcc_target): Add branch_target_register_class and branch_target_register_callee_saved members. * toplev.c (enum dump_file_index): Add DFI_branch_target_load (dump_file) Add "tars" entry. (flag_branch_target_load_optimize): New variable. (flag_branch_target_load_optimize2): Likewise. (lang_independent_options): Add entries for new options. (rest_of_compilation): Call branch_target_load_optimize. * doc/tm.texi (TARGET_BRANCH_TARGET_REGISTER_CLASS): Document. (TARGET_BRANCH_TARGET_REGISTER_CALLEE_SAVED): Likewise. * doc/invoke.texi: Document -fbranch-target-load-optimize and -fbranch-target-load-optimize2. * rtl.h (epilogue_completed): Declare. * recog.c (epilogue_completed): New variable. * toplev.c (rest_of_compilation): Set it. * flow.c (mark_regs_live_at_end): Use it. * config/ia64/ia64.c (ia64_output_mi_thunk): Set it. * config/rs6000/rs6000.c (rs6000_output_mi_thunk): Likewise. * config/sh/sh.c (sh_output_mi_thunk): Likewise. * config/sparc/sparc.c (sparc_output_mi_thunk): Likewise. * sh.c (shmedia_space_reserved_for_target_registers): New variable. (sh_target_reg_class): New function. (sh_optimize_target_register_callee_saved): Likwise. (shmedia_target_regs_stack_space): Likewise. (shmedia_reserve_space_for_target_registers_p): Likewise. (shmedia_target_regs_stack_adjust): Likewise. (TARGET_BRANCH_TARGET_REGISTER_CLASS): Override. (TARGET_BRANCH_TARGET_REGISTER_CALLEE_SAVED): Likewise. (calc_live_regs): If flag_branch_target_load_optimize2 and TARGET_SAVE_ALL_TARGET_REGS is enabled, and we have space reserved for target registers, make sure that we save all target registers. (sh_expand_prologue, sh_expand_epilogue): Take target register optimizations into account. Collapse stack adjustments if that is beneficial. (initial_elimination_offset): Reserve space for target registers if necessary. * sh.h (SAVE_ALL_TR_BIT, TARGET_SAVE_ALL_TARGET_REGS): Define. (OPTIMIZATION_OPTIONS): Enable flag_branch_target_load_optimize. Co-Authored-By: J"orn Rennecke <joern.rennecke@superh.com> From-SVN: r68165
