...n outstanding issue with using the Alias Set Tracker due to its expensive construction time (quadratic). We've had test cases take forever to compile, where the largest time was spent constructing the AST in LICM. We've also had to degrade the AST results as a temporary fix to resolve this (D23432). The hope is that by using MemorySSA instead, which has linear construction time, we can avoid this issues and decrease compile times. Some initial discussion points: 1. As a first step, I'm looking at having MemorySSA as a dependency only for LICM, in the old pass manager. 2. In the future,...
