https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234987 --- Comment #2 from commit-hook@freebsd.org --- A commit references this bug: Author: dim Date: Wed Jan 16 20:38:18 UTC 2019 New revision: 343102 URL: https://svnweb.freebsd.org/changeset/base/343102 Log: Pull in r337861 from upstream llvm trunk (by Hideki Saito): [LV] Fix for PR38110, LV encountered llvm_unreachable() Summary: truncateToMinimalBitWidths() doesn't handle all Instructions and the worst case is compiler crash via llvm_unreachable(). Fix is to add a case to handle PHINode and changed the worst case to NO-OP (from compiler crash). Reviewers: sbaranga, mssimpso, hsaito Reviewed By: hsaito Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D49461 This should fix "Unhandled instruction type!" (if assertions are enabled) or segmentation faults (if assertions are disabled) when compiling certain versions of the net-p2p/gtk-gnutella port. Direct commit to stable/11 and stable/12, since head already has this fix.
