INTERNAL ERROR: Number of virtual registers beyond limit. Reduce function size

Hi Guys,

I try to compile the attached file with the compiler TI v6.4.11.
I'm getting the error message:

INTERNAL ERROR: Number of virtual registers beyond limit. Reduce function size

I see someone posted the same error before. But my problem is different from his.

In my code, I need to do a lot of matrix calculation. The memcpy method does not work here.

Looking for reply.

Thank you

Best Regards,

Bruce

Unfortunately, your example does not build. Types are missing, variables are missing definitions, etc. Please preprocess the source file which contains this function, and submit that. Also show the build options exactly as the compiler sees them.

Thanks and regards,

This message indicates that the compiler is unable to handle a very large function. To work around this problem, you will need to reduce the complexity of the function, perhaps by breaking it up into smaller functions. Please note that this limit has been raised for the very latest compiler releases. In particular, C2000 release 16.9.0.LTS shouldn't have this problem.

Hi Archaeologist,
I updated to the latest compiler version and solved the problem. Thank you!
