[lldb-dev] lldb warning or developer options
Hi Folks, Is their a developer switch or diagnostic switch, that we can set in lldb, to show warnings and other useful stuff when lldb process the binary, building table and utilizing DWARF. I stumble upon, a rather trivial test case. where I deleted the *.dwo file. and loaded primary binary in lldb. lldb loaded it silently without any error or diagnostic reports for not found *.dwo file. Obviously, debug data wasn't loaded, as I entered list command, nothing happened. Why need this, as new dwarf-5 features are in development, if lldb can report some diagnostics like section not found or ill-formed section, this would be immensely useful .

[lldb-dev] How/where to add test cases in LLDB.
Hello Everyone, I've wrote a patch for extending support for new forms[DWARFv5] in macro section. Planning to file a review soon. But I'm stuck with writing test case for this. My feature works well when using LLDB in interactively, but I need to write a test case to accompany my patch. To put things in perspective: here' s how I tested it interactively: $lldb a.out $display MACRO1 -- macro defined in source/a.out $ b main $ run LLDB output - Hook 1 (expr -- MACRO1) (int) $0 = 4 Process 18381 stopped * thread #1, name = 'a.out', stop reason = breakpoint 1.1 Need to write/add test case for this so that it will be run by "make check-lldb", any ideas/pointers how to proceed forward from here. Thanks in anticipation! Sourabh Singh Tomar ___ lldb-dev mailing list lldb-dev@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev
