https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227698 --- Comment #10 from commit-hook@freebsd.org --- A commit references this bug: Author: dim Date: Mon Apr 23 23:07:58 UTC 2018 New revision: 332898 URL: https://svnweb.freebsd.org/changeset/base/332898 Log: Pull in r329771 from upstream llvm trunk (by Craig Topper): [X86] In X86FlagsCopyLowering, when rewriting a memory setcc we need to emit an explicit MOV8mr instruction. Previously the code only knew how to handle setcc to a register. This should fix a crash in the chromium build. This fixes various assertion failures while building ports targeting i386: * www/firefox: isReg() && "This is not a register operand!" * www/iridium, www/qt5-webengine: (I.atEnd() || std::next(I) =3D=3D def_instr_end()) && "getVRegDef assumes a single definition or no definition" * devel/powerpc64-gcc: FromReg !=3D ToReg && "Cannot replace a reg with itself" Reported by: jbeich PR: 225330, 227686, 227698, 227699 MFC after: 1 week X-MFC-With: r332833 Changes: head/contrib/llvm/lib/Target/X86/X86FlagsCopyLowering.cpp --=20 You are receiving this mail because: You are on the CC list for the bug.=
