with LTO enabled results in:
ld:
/home/bero/abf/llvm/BUILD/llvm-project-release-12.x/llvm/lib/Analysis/InstructionPrecedenceTracking.cpp:87:
void llvm::InstructionPrecedenceTracking::validate(const llvm::BasicBlock *)
const: Assertion `It->second == &Insn && "Cached first special instruction is
wrong!"' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace.

clang-12: error: unable to execute command: Aborted (core dumped)
clang-12: error: linker command failed due to signal (use -v to see invocation)
Without LTO, it compiles and works fine.
