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