# This test aims to check what the default rounding mode is for a given
# instruction if it's not specified, and ensures that it isn't printed when
# aliases are enabled but is printed otherwise. Instructions aren't listed
# exhaustively, but special attention is given to the fcvt instructions given
# that those that never round often default to frm=0b000 for historical
# reasons.
#
# These test cases are copied from fp-default-round-mode.s, but changed to use
# GPRs.
