  12 # This test aims to check what the default rounding mode is for a given
  13 # instruction if it's not specified, and ensures that it isn't printed when
  14 # aliases are enabled but is printed otherwise. Instructions aren't listed
  15 # exhaustively, but special attention is given to the fcvt instructions given
  16 # that those that never round often default to frm=0b000 for historical
  17 # reasons.
