md.texi (Defining Attributes): Document that we are defining HAVE_ATTR_name macors as 1 for defined attributes...
* doc/md.texi (Defining Attributes): Document that we are defining
HAVE_ATTR_name macors as 1 for defined attributes, and as 0
for undefined special attributes.
* final.c (asm_insn_count, align_fuzz): Always define.
(insn_current_reference_address): Likewise.
(init_insn_lengths): Use if (HAVE_ATTR_length) instead of
#ifdef HAVE_ATTR_length.
(get_attr_length_1, shorten_branches, final): Likewise.
(final_scan_insn, output_asm_name): Likewise.
* genattr.c (gen_attr): Define HAVE_ATTR_name macros for
defined attributes as 1.
Remove ancient get_attr_alternative compatibility code.
For special purpose attributes not provided, define HAVE_ATTR_name
as 0.
In case no length attribute is given, provide stub definitions
for insn_*_length* functions, and also include insn-addr.h.
In case no enabled attribute is given, provide stub definition.
* genattrtab.c (write_length_unit_log): Always write a definition.
* hooks.c (hook_int_rtx_1, hook_int_rtx_unreachable): New functions.
* hooks.h (hook_int_rtx_1, hook_int_rtx_unreachable): Declare.
* lra-int.h (struct lra_insn_recog_data): Make member
alternative_enabled_p unconditional.
* lra.c (free_insn_recog_data): Use if (HAVE_ATTR_length) instead of
#ifdef HAVE_ATTR_length.
(lra_set_insn_recog_data): Likewise. Make initialization of
alternative_enabled_p unconditional.
(lra_update_insn_recog_data): Use #if instead of #ifdef for
HAVE_ATTR_enabled.
* recog.c [!HAVE_ATTR_enabled] (get_attr_enabled): Don't define.
(extract_insn): Check HAVE_ATTR_enabled.
(gate_handle_split_before_regstack): Use #if instead of
#if defined for HAVE_ATTR_length.
