Hi,
Please see the following tool chain
CPP=arm-none-linux-gnueabi-gcc
SWS=-march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -flax-vector-conversions
Target is beegle board
How can i disable the vectorization.
If i give the above tool chain, it will create a default vectorized code for the given C source
if i write the NEON C intrinsics then will the compiler overrides its optimization and use the programmer neon direction.
Please help me to solve the doubts
