* read-rtl.c (map_value, mapping, macro_group): New structures.
(BELLWETHER_CODE): New macro.
(modes, codes, bellwether_codes): New variables.
(find_mode, uses_mode_macro_p, apply_mode_macro, find_code)
(uses_code_macro_p, apply_code_macro, apply_macro_to_string)
(apply_macro_to_rtx, uses_macro_p, add_condition_to_string)
(add_condition_to_rtx, apply_macro_traverse, add_mapping)
(add_map_value, initialize_macros): New functions.
(def_hash, def_hash_eq_p): Generalize to anything that points to,
or starts with, a char * field.
(find_macro, read_mapping, check_code_macro): New functions.
(read_rtx_1): New, split out from read_rtx. Handle the new
define_{mode,code}_{macro,attr} constructs. Use find_macro
to parse the name of a code or mode. Use BELLWETHER_CODE to
extract the format and to choose a suitable code for rtx_alloc.
Modify recursive invocations to use read_rtx_1.
(read_rtx): Call initialize_macros. Apply code and mode macros
to the rtx returned by read_rtx_1. Cache everything after the
first macro expansion for subsequent read_rtx calls.
* doc/md.texi: Document new .md constructs.
* config/mips/mips.md (GPR): New mode macro.
(d, si8_di5): New mode attributes.
(any_cond): New code macro.
(add[sd]i3): Redefine using :GPR.
(*add[sd]i3): Likewise, renaming from add[sd]i3_internal.
(*add[sd]i3_sp[12], *add<mode>3_mips16): Redefine using :GPR, naming
previously unnamed MIPS16 patterns.
(*addsi3_extended): Renamed from addsi3_internal_2. Fix overly long
lines. Don't match (plus (const_int 0) ...).
(*addsi3_extended_mips16): Name previously unnamed MIPS16 pattern.
Use a define_split to generate the addition.
(sub[sd]i3): Redefine using :GPR. Turn subsi3 into a define_insn.
(subsi3_internal): Delete.
(*subsi3_extended): Renamed from subsi3_internal_2.
(bunordered, bordered, bunlt, bunge, buneq, bltgt, bunle, bungt)
(beq, bne, bgt, bge, blt, ble, bgtu, bgeu, bltu, bleu): Redefine
using an any_cond template.
