Well, maybe it's not always true, lldb searches suitable place in memory for mapping as you've said, but according to logs, usually stack memory is used (please, take a look https://github.com/llvm/llvm-project/pull/99336#discussion_r1692134445, https://github.com/llvm/llvm-project/pull/99336#issuecomment-2242837459) > Maybe you're referring to jumps from that JIT'd code back to code in the > binary, that those jumps may be too large? Yep. Even if lldb hasn't used stack memory exactly, we can't guarantee that selected region will be close enough to code in the binary to make a jump. https://github.com/llvm/llvm-project/pull/99336 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
