Date: Thu, 11 Jun 2015 10:33:00 -0000 [thread overview] Message-ID: <bug-56766-4-3voZa4E5ef@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-56766-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=56766 --- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> --- So it works with (define_insn "sse3_addsubv2df3" [(set (match_operand:V2DF 0 "register_operand" "=x,x") (vec_select:V2DF (vec_concat:V4DF (plus:V2DF (match_operand:V2DF 1 "register_operand" "0,x") (match_operand:V2DF 2 "nonimmediate_operand" "xm,xm")) (minus:V2DF (match_dup 2) (match_dup 1))) (parallel [(const_int 0) (const_int 3)])))] but not with (define_insn "sse3_addsubv2df3" [(set (match_operand:V2DF 0 "register_operand" "=x,x") (vec_select:V2DF (vec_concat:V4DF (plus:V2DF (match_operand:V2DF 1 "register_operand" "0,x") (match_operand:V2DF 2 "nonimmediate_operand" "xm,xm")) (minus:V2DF (match_dup 1) (match_dup 2))) (parallel [(const_int 0) (const_int 3)])))]
