Subject: [PATCH 055/157] [Backport][SME] recog: Support space in "[ cons"
Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=9d31045b21324166c3997d603961d99e3c4c357d
Hi all,
this is to allow for spaces before "cons:" in the definitions of
patterns using the new compact syntax, ex:
(define_insn "aarch64_simd_dup<mode>"
[(set (match_operand:VDQ_I 0 "register_operand")
(vec_duplicate:VDQ_I
(match_operand:<VEL> 1 "register_operand")))]
"TARGET_SIMD"
{@ [ cons: =0 , 1 ; attrs: type ]
[ w , w ; neon_dup<q> ] dup\t%0.<Vtype>, %1.<Vetype>[0]
[ w , ?r ; neon_from_gp<q> ] dup\t%0.<Vtype>, %<vwcore>1
}
)

in new compact pattern syntax.
