I tried to compile NEON assembly with the following example by CCS5.1, but it is fail.

Please refer to the attached file.

And I google the information, it said CCS5 don't support NEON intrinsics, is it really?

If so, have any body tell me which compile you have used and changed CCS5 build tool?

.text

.arm

.global double_elements

double_elements:

vadd.i32 q0,q0,q0

bx lr

.end

What build options are you using? The TI ARM compiler does support NEON instruction with the --neon option enabled. Please refer to the ARM compiler Users Guide for more information on the option.

Thank you for your answer.

Yes, I did it.

Please refer to the following my option.

"C:/ti/ccsv5/tools/compiler/tms470_4.9.5/bin/cl470" -mv7A8 --code_state=32 --abi=eabi -me -O2 --opt_for_speed=2 --include_path="C:/ti/ccsv5/tools/compiler/tms470_4.9.5/include" --define=am3359 --diag_warning=225 --display_error_number --neon --preproc_with_compile

Have any problem?

is the complete assembly file what you had posted in your original post? I did not get any errors compiling that with the options you are using. What errors are you seeing? Please post the complete source file and the otuput/errors you see in the CCS build console.

Hi.

Can ARM NEON instrinsics below link be compiled in CCS?

http://gcc.gnu.org/onlinedocs/gcc/ARM-NEON-Intrinsics.html

Could you kindly let me know how to include and build the intrinsics in CCS?

Thank you.

Regards,

Johnny
