Add
target modules dump separate-debug-info
(llvm#66035)
Add a new command ``` target modules dump separate-debug-info [-j] [<filename> [<filename> [...]]] ``` or ``` image dump separate-debug-info [-j] [<filename> [<filename> [...]]] ``` (since `image` is an alias for `target modules`). This lists the separate debug info files and their current status (loaded or not loaded) for the specified modules. This diff implements this command for mach-O files with OSO and ELF files with dwo. Example dwo: ``` (lldb) image dump separate-debug-info Symbol file: /home/toyang/workspace/dwo-scratch/a.out Type: "dwo" Dwo ID Err Dwo Path ------------------ --- ----------------------------------------- 0x9a429da5abb6faae /home/toyang/workspace/scratch-dwo/a-main.dwo 0xbcc129959e76ff33 /home/toyang/workspace/scratch-dwo/a-foo.dwo (lldb) image dump separate-debug-info -j [ { "separate-debug-info-files": [ { "comp_dir": "/home/toyang/workspace/dwo-scratch", "dwo_id": 11115620165179865774, "dwo_name": "a-main.dwo", "loaded": true, "resolved_dwo_path": "/home/toyang/workspace/dwo-scratch/a-main.dwo" }, { "comp_dir": "/home/toyang/workspace/dwo-scratch", "dwo_id": 13601198072221073203, "dwo_name": "a-foo.dwo", "loaded": true, "resolved_dwo_path": "/home/toyang/workspace/dwo-scratch/a-foo.dwo" } ], "symfile": "/home/toyang/workspace/dwo-scratch/a.out", "type": "dwo" } ] ``` Example dwo with missing dwo: ``` (lldb) image dump separate-debug-info Symbol file: /home/toyang/workspace/dwo-scratch/a.out Type: "dwo" Dwo ID Err Dwo Path ------------------ --- ----------------------------------------- 0x9a429da5abb6faae E unable to locate .dwo debug file "/home/toyang/workspace/scratch-dwo/b.out-main.dwo" for skeleton DIE 0x0000000000000014 0xbcc129959e76ff33 E unable to locate .dwo debug file "/home/toyang/workspace/scratch-dwo/b.out-foo.dwo" for skeleton DIE 0x000000000000003c (lldb) image dump separate-debug-info -j [ { "separate-debug-info-files": [ { "comp_dir": "/home/toyang/workspace/dwo-scratch", "dwo_id": 11115620165179865774, "dwo_name": "a-main.dwo", "error": "unable to locate .dwo debug file \"/home/toyang/workspace/dwo-scratch/a-main.dwo\" for skeleton DIE 0x0000000000000014", "loaded": false }, { "comp_dir": "/home/toyang/workspace/dwo-scratch", "dwo_id": 13601198072221073203, "dwo_name": "a-foo.dwo", "error": "unable to locate .dwo debug file \"/home/toyang/workspace/dwo-scratch/a-foo.dwo\" for skeleton DIE 0x000000000000003c", "loaded": false } ], "symfile": "/home/toyang/workspace/dwo-scratch/a.out", "type": "dwo" } ] ``` Example output with dwp: ``` (lldb) image dump separate-debug-info Symbol file: /home/toyang/workspace/dwo-scratch/a.out Type: "dwo" Dwo ID Err Dwo Path ------------------ --- ----------------------------------------- 0x9a429da5abb6faae /home/toyang/workspace/dwo-scratch/a.out.dwp(a-main.dwo) 0xbcc129959e76ff33 /home/toyang/workspace/dwo-scratch/a.out.dwp(a-foo.dwo) (lldb) image dump separate-debug-info -j [ { "separate-debug-info-files": [ { "comp_dir": "/home/toyang/workspace/dwo-scratch", "dwo_id": 11115620165179865774, "dwo_name": "a-main.dwo", "loaded": true, "resolved_dwo_path": "/home/toyang/workspace/dwo-scratch/a.out.dwp" }, { "comp_dir": "/home/toyang/workspace/dwo-scratch", "dwo_id": 13601198072221073203, "dwo_name": "a-foo.dwo", "loaded": true, "resolved_dwo_path": "/home/toyang/workspace/dwo-scratch/a.out.dwp" } ], "symfile": "/home/toyang/workspace/dwo-scratch/a.out", "type": "dwo" } ] ``` Example oso on my Mac: ``` (lldb) image dump separate-debug-info Symbol file: /Users/toyang/workspace/scratch/a.out Type: "oso" Mod Time Err Oso Path ------------------ --- --------------------- 0x0000000064e64868 /Users/toyang/workspace/scratch/foo.a(foo.o) 0x0000000064e64868 /Users/toyang/workspace/scratch/foo.a(main.o) (lldb) image dump separate-debug-info -j [ { "separate-debug-info-files": [ { "loaded": true, "oso_mod_time": 1692813416, "oso_path": "/Users/toyang/workspace/scratch/foo.a(foo.o)", "so_file": "/Users/toyang/workspace/scratch/foo.cpp" }, { "loaded": true, "oso_mod_time": 1692813416, "oso_path": "/Users/toyang/workspace/scratch/foo.a(main.o)", "so_file": "/Users/toyang/workspace/scratch/main.cpp" } ], "symfile": "/Users/toyang/workspace/scratch/a.out", "type": "oso" } ] ``` Test Plan: Tested on Mac OS and Linux. ``` lldb-dotest -p TestDumpDwo lldb-dotest -p TestDumpOso ``` --------- Co-authored-by: Tom Yang <[email protected]>
