md.texi: Document "preferred_for_size" and "preferred_for_speed" attributes.
gcc/
* doc/md.texi: Document "preferred_for_size" and "preferred_for_speed"
attributes.
* genattr.c (main): Handle "preferred_for_size" and
"preferred_for_speed" in the same way as "enabled".
* recog.h (bool_attr): New enum.
(target_recog): Replace x_enabled_alternatives with x_bool_attr_masks.
(get_preferred_alternatives, check_bool_attrs): Declare.
* recog.c (have_bool_attr, get_bool_attr, get_bool_attr_mask_uncached)
(get_bool_attr_mask, get_preferred_alternatives, check_bool_attrs):
New functions.
(get_enabled_alternatives): Use get_bool_attr_mask.
* ira-costs.c (record_reg_classes): Use get_preferred_alternatives
instead of recog_data.enabled_alternatives.
* ira.c (ira_setup_alts): Likewise.
* postreload.c (reload_cse_simplify_operands): Likewise.
* config/i386/i386.c (ix86_legitimate_combined_insn): Likewise.
* ira-lives.c (preferred_alternatives): New variable.
(process_bb_node_lives): Set it.
(check_and_make_def_conflict, make_early_clobber_and_input_conflicts)
(single_reg_class, ira_implicitly_set_insn_hard_regs): Use it instead
of recog_data.enabled_alternatives.
* lra-int.h (lra_insn_recog_data): Replace enabled_alternatives
to preferred_alternatives.
* lra-constraints.c (process_alt_operands): Update accordingly.
* lra.c (lra_set_insn_recog_data): Likewise.
(lra_update_insn_recog_data): Assert check_bool_attrs.
