Loop unrolling in Microblaze C programming using EDK

[heshsham]

Hi,

I am a first time user of Microblaze.  

To increase my system performance, I am planning to use loop unrolling.

Do I have this feature available in programming MicroBlaze in C using EDK?

Thanks and regards,

I'd have a look here:

http://gcc.gnu.org/onlinedocs/gcc-3.3.6/gcc/Optimize-Options.html

Particularly, the -funroll-loops section.

The different -O optimization switchs (available directly in the SDK GUI) may do loop unrolling because it enables -floop-optimize which states:

-floop-optimize

Perform loop optimizations: move constant expressions out of loops, simplify exit test conditions and optionally do strength-reduction and loop unrolling as well.

Enabled at levels-O,-O2,-O3,-Os.

Thanks a lot for your reply.  This should help me to a great extent.
