Linker errors while using C6000 Intrinsics

Hi,

While trying to optimise my work, I was trying to add some intrinsics to my code that runs on C6713 platform. The particular one I tried to use was _cmpeq4 however I got linker errors (i.e. symbol referencing errors) that I was not expecting. According to spru198.pdf, the intrinsics are recognised by the compiler and therefore should not cause any issues. I am not sure if I forgot to include/link to a particular library. I am sure I am missing something here but I just can't see it !

If any fellow members can provide me with some pointers, that would be very helpful.

Thank you in advance for your time and effort.

 

Regards...

    Hello again :)

    I think I spotted the problem !

    The intrinsics are defined in c6x.h file. When I checked this file, I realised that the _cmpeq4 intrinsic is within the _TMS320C6400 compiler switch and therefore it cannot be used on my platform. I randomly picked an intrinsic witihin the _TMS320C6700 switch (namely, _fabs() ) and my code compiled and linked as expected.

    I hope this note helps a few other members as well.
