I'm writing a compiler using LLVM, and suddenly today I started to get this error, when emitting to a .s file. Assertion failed: (I != M+Size && I->FromReg == RegNum && "Invalid RegNum"), function getLLVMRegNum, file MCRegisterInfo.cpp, line 78. I'm emitting using x86_64-apple-darwin. Any thoughts about what could be causing this? LLVM validation does not report any errors.

Hi I come across the following exception when I use the llvm-dwarfdump -debug-info target_binary: llvm-dwarfdump: /home/linux/llvm-7/llvm/lib/MC/MCRegisterInfo.cpp:87: int llvm::MCRegisterInfo::getLLVMRegNum(unsigned int, bool) const: Assertion `I != M+Size && I->FromReg == RegNum && "Invalid RegNum"' failed.

...I just want to have it output the same register number as before (the same output the false path would produce). void MCAsmStreamer::EmitRegisterName(int64_t Register) { if (InstPrinter) { const TargetAsmInfo &asmInfo = getContext().getTargetAsmInfo(); unsigned LLVMRegister = asmInfo.getLLVMRegNum(Register, true); InstPrinter->printRegName(OS, LLVMRegister); } else { OS << Register; } } My current implementation of printRegName which I copied from other backends (X86, ARM and PowerPC) looks like this: void MipsInstPrinter::printRegName(raw_ostream &OS, unsigned Reg...
