   5
   6 lmw, lswi and related PowerPC insns aren't allowed on ppc64le
   7
   8 Newer binutils produce an error when the assembly contains lmw, stmw,
   9 lswi, lswx, stswi, or stswx instructions in little-endian mode.
  10
  11 Only build and run the lsw and ldst_multiple testcases on ppc64[be].
