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.
