@Archeologist,
Matt mentioned compiler versions 5.1 and 6.0.8.
@George,
Should the _mpyidll intrinsic show up for -mv6700 also? Or is there a different intrinsic for the C6713 that Matt is using? The MPYID instruction looks to be valid for the C6713 according to the C67x/C67x+ CPU & Instruction Set document. Could this be a problem with long long not being defined for the C6713, or something like that?
@Matt,
Can you try a newer version than 6.0.8, like the latest 6.1.x?
Regards,
RandyP
