Vectorizing Compiler

Note: This was originally posted on 29th June 2010 at http://forums.arm.com

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

Dear scott,

the tool chain version is given below

I have one doubt will my code can enter the cache memory..?

The OS critical module can use the cache all the time.?
