With the second patch + valley I get - valley_x64: LiveVariables.cpp:114: void llvm::LiveVariables::MarkVirtRegAliveInBlock(llvm::LiveVariables::VarInfo &, llvm::MachineBasicBlock *, llvm::MachineBasicBlock *, std::vector<MachineBasicBlock *> &): Assertion `MBB != &MF->front() && "Can't find reaching def for virtreg"' failed.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
