Reducing VGPRs usage II

Question asked by boxerab on Aug 28, 2015

I have a kernel that gets only 20% occupancy due to VGPRs usage. Currently, I am using 97 VGPRs as reported by CodeXL.

If I can get this down to 84 registers, then CodeXL reports that I get a bump in occupancy.

 

Is it realistic to reduce VGPRs from 97 to 84 ? i.e. around 13% reduction.
