<pre>
    External profilers might want to do DWARF based unwinding if the JIT code was built with frame-pointer-optimization.

This was introduced in 2016 for V8 https://groups.google.com/g/linux.kernel/c/sq5WbV7xaec?pli=1 and so far LLVM politely ignores it https://github.com/llvm/llvm-project/blob/ee9a0f30ca8a3582d0738f7499ea902e1f713b39/llvm/lib/ExecutionEngine/PerfJITEvents/PerfJITEventListener.cpp#L113

I won't have time to work on this, but wanted to leave some breadcrumbs around why we disabled FPO in Julia https://github.com/JuliaLang/julia/pull/48660
