Author: dim Date: Thu Jan 18 21:44:07 2018 New Revision: 328145 URL: https://svnweb.freebsd.org/changeset/base/328145 Log: Pull in r322016 from upstream llvm trunk (by Sanjay Patel): [ValueTracking] remove overzealous assert The test is derived from a failing fuzz test: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=5008 Credit to @rksimon for pointing out the problem. This should fix "Bad flavor while matching min/max" errors when building the graphics/libsixel and science/kst2 ports.
