/* This file tests the GAS's ability in assembling the alias mnemonics
   of sbfm, bfm and ubfm.  Disassembler should prefer to use alias
   mnemonics to display {[u|s]}bfm instructions.
   bitfield-bfm.s and bitfield-alias.s will be assembled into idential
   binary, which is why the two tests share the same dump match
   file 'bitfield-dump'.
   This assembly file is also used for the bitfield-no-aliases test.  */
