<pre>Hi,
NEON is indeed optional for ARMv7-A cores, however it is on by default. It is
possible to disable NEON by specifying the -mfpu option to a VFP unit (not
"neon"):
./bin/clang --target=arm-linux-unknown-gnueabihf -march=armv7-a -mcpu=generic
-O2 x.c -o - -S -mfpu=vfpv3
... snip ...
vldr d0, .LCPI0_0
... snip ...</pre>
