Seems there were a couple of correlated failures that appear to be flakes on this buildbot recently: green: http://lab.llvm.org:8011/builders/clang-ppc64le-linux-multistage/builds/13974 red: http://lab.llvm.org:8011/builders/clang-ppc64le-linux-multistage/builds/13975 (target-override.c during stage 1, seems to be missing the directory/symlink it just created) red:

Hi All, We have recently found some optimization opportunities created by replicating code into branches in order to enable optimization. In general, the optimization opportunity we are pursuing is like the following. Given pseudo-code: // block A if (some condition) // block B // block C If it can be efficiently proven that some portion of block C can be simplified had control flow not
