| 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]. |
