qnx 7.1 compiler supports arm neon for a78 architecture?

Hello,

I am building and running arm neon code which is generated from matlab. Target device is a78 and it is running on qnx.

I checked the generated code contains arm neon intrinsica and header file. -mcpu option does support a78 exactly so I selected a little lower architecture. Builing is successful but the performance improvement was not observed.

I am wondering that arm neon for a78 in qnx 7.1 is supported or not. How do I check?

Regards,
