how to run compile code for NEON

Note: This was originally posted on 18th December 2009 at http://forums.arm.com

Hello everyone,
I'm trying RVDS4.0 evaluation copy and i'm not able to get any option in RVDS that can compile my code in NEON instruction set.As a starting point,I've written simple addition C file with following option.:
--cpu=Cortex-A8 --fpu=VFPv2 -O3 -Otime --vectorize

The error i'm getting is:
armlink: Object main.o attributes are not compatible with provided cpu and fpu attributes.

I searched on internet and i found most people are using this option:
-mpfu=neon -ftree-vectorize -mfloat-abi=softfp
"i don't know how to set my fpu to neon"

Please reply ASAP
Regards
S

Hello Marcus,
First,thanks for the early reply.
It seems to me ,i need to have some support code in order to use VFPv3 in my code.(I'm basically trying a code for NEON on CORTEX A8).
I even found a application note for this(http://infocenter.arm.com/help/topic/com.arm.doc.dai0133c/DAI0133C_Using_VFP_with_RVDS.pdf).

Thanks for the info.
