Compilation output including backtrace
The following assertion failure has been seen with llvm-7.0.0:
clang-7:
/home/phargrov/llvm-7.0.0.src/lib/CodeGen/AsmPrinter/AsmPrinter.cpp:1759: void
llvm::AsmPrinter::EmitJumpTableEntry(const llvm::MachineJumpTableInfo*, const
llvm::MachineBasicBlock*, unsigned int) const: Assertion `MBB &&
MBB->getNumber() >= 0 && "Invalid basic block"' failed.
However, 4.0, 5.0 and 6.0 show the same, while 3.7 and 3.8 do not.
The same code does not generate any such failure on (at least) x86, x86-64,
arm, aarch64, sparc64 (for various 4.0, 5.0 or 6.0 versions).</pre>
