restrict qualifier for const arrays/references

Soeren Reitz

hey guys, I have big trouble with the the restrict qualifier in c++ sourcecode. In case I'm optimizing some sourcecode. The sourcecode contains mostly references to arrays. So here my questions.

Does the restrict qualifier the same effect on references like on arrays?

and

May 'const read only arrays' or references generally set to restict for better dsp processing?

big thanks soren

    Hi Soeren,

    yes, to avoid the ovelapping of memory and to guarantee the correct memory access by the pointers or references.

    The detailed information on "restrict" qualifier is given at the "C6000 C/C++ Optimizing Compiler v7.0 User's Guide" http://www.ti.com/lit/ug/spru187q/spru187q.pdf particularly in section, 6.4.5

    You can use the TI compiler forum for this type of queries.

    One good example of how restrict is typically used can be found in this wiki article.
