| 4 | Subject: [PATCH] lmw, lswi and related PowerPC insns aren't allowed on ppc64le |
| 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]. |
