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