invokeO0EPCallbacks? I saw there is `PassBuilder::invokePeepholeEPCallbacks`.
================
Comment at: llvm/lib/Passes/PassBuilder.cpp:1659
+ bool DebugLogging) {
+ for (auto &C : PipelineStartEPCallbacks)
+ C(MPM);
----------------
What I have in mind is a newly added `O0EPCallbacks` field in PassBuilder
class. Then we can keep existing EPCallbacks (including
PipelineStartEPCallbacks) for >O0 optimization pipeline. Yeah, then you need to
add related passes to O0EPCallbacks (for BPF in this case).
