| 4 | Subject: [PATCH] avoid neon for targets which don't support it |
| 5 | |
| 6 | The sh-mem-random.c test app tries to use neon loads and stores to |
| 7 | test 64-bit float copies when building for ARM. Allow it to do so if |
| 8 | possible, but fallback to C when building for ARM targets which don't |
| 9 | support neon. |
