Hi, can you please share steps for us to repro the issue? What’s the program you’re running perf2bolt on, the OS, which compiler is used with which options.

self develop program

@zpget Hello.
Will the -fno-reorder-blocks-and-partition flag make any difference?

add -fno-reorder-blocks-and-partition remian the same core
bolt:llvm/tools/llvm-bolt/src/BinaryContext.cpp:577: bool llvm::bolt::BinaryContext::analyzeJumpTable(uint64_t, llvm::bolt::JumpTable::JumpTableType, llvm::bolt::BinaryFunction&, uint64_t, llvm::bolt::JumpTable::OffsetsType*): Assertion `JumpTableBD->getEndAddress() <= UpperBound && "data object cannot cross a section boundary"' failed.

Thank you for more details! Thank you @yota9 for on-spot suggestion.
One thing I've noticed is that you don't have options to preserve relocations in the resulting binary.
Can you please add -Wl,--emit-relocs -znow to you compilation flags and verify if the issue persists?
