We tested different cap values with a recent commit of Chromium. Our results show that the 32-byte cap yields the smallest binary and all the caps yield similar performance. Based on the results, we propose to change the cap value to 32-byte. Patch by Zhaomo Yang! Differential Revision: https://reviews.llvm.org/D49405 llvm-svn: 337622
