Author: mamai Date: Wed May 4 10:26:28 2016 New Revision: 268509 URL: http://llvm.org/viewvc/llvm-project?rev=268509&view=rev Log: Do not disable completely loop unroll when optimizing for size.
Let the loop unroll pass handle /Os. It already checks that option and adjust its thresholds accordingly. Also, will allow the #pragma unroll to have an effect in /Os.
