I've been trying to profile jitted code with Perf with no success.
I've tried with LLVM 13.1, LLVM 14 and LLVM 15, all compiled with `LLVM_USE_PERF=1`
I've tried to simulate the following steps:
`perf record -k 1 -g lli --jit-kind=mcjit expensive_loop.ll`
`perf inject --jit -i perf.data -o perf.data.jitted`
`perf report -i perf.data.jitted`
lli is generating the .dump file and injecting them is creating the shared objects as expected, but when I use `report` the symbols are not resolved to their expected functions, all I can see are the addresses.
I'm honestly at a loss of what to do. I've tried [this fix ](https://discourse.llvm.org/t/how-to-correctly-use-perfjiteventlistener/50849/2), and still got nothing.
Any help would be appreciated
