Re: Question about i386.md and 32-bit and 64-bit split and peephole rules

Hello! As I noticed are some parts in i386.md existing for just for 32-bit, but will be used in 64-bit, too. For example: (define_split [(set (match_operand:XF 0 "push_operand" "") (float_extend:XF (match_operand:SF 1 "fp_register_operand" "")))] "" [(set (reg:SI SP_REG) (plus:SI
